Hello, friends, and welcome back to another episode of the Juice Box Podcast. On today's episode, Jenny and I are going to try to give names to the shapes that you see on your graph. So when you're looking at your CGM and you start low and it goes up high really quickly and comes back down, what do we call that? Is it a spike? Is it a peak? And what about the graphs that look like roller coaster tracks? Or how about those quick drops that come back up again? We're going to try to define them, to give them names so that we can talk about them on the podcast, so that we can take your graphs and try to figure them out on an audio show in a way that will allow you to follow along. Let's see if we can do it. Please don't forget that nothing you hear on the Juice Box Podcast should be considered advice, medical or otherwise. Always consult a physician before making any changes to your healthcare plan or becoming bold with insulin.

B
Yay.
A
I do not know if we're going to be successful.
B
Okay, this is a new idea.
A
It's a completely new idea.
B
Yay.
A
I don't know how successful we're going to be, but I'd like to try to quantify the different graphs on a CGM with words and give them names so that we can later make episodes where we talk about graphs in a way that people who don't have a visual can follow along with. Okay, so we have to identify the shapes, the pathway of the dots on a cgm and then give them a fun name that people can remember.
B
Oh, okay.
A
All right.
B
Well, I can. I mean, I can think of one, like when you're talking about graphs, and I've used it a million times before. Right. When you're eating real food or a mix of foods that contain carbohydrates. And we've talked about it in terms of insulin timing and what things should look like on a graph. It should look somewhat like a bell Curve, if people are familiar with that term. Your insulin, right? Blood sugar should go up some. You, you might have a target range you want to stick with, but that up should plateau and then it should nicely curve back down so that by the time the bolus is done working and your basal is well set, it lands you and you stay stable. Okay, that's one I can think of.
A
That's awesome. So I'm putting bell curve here on my list. I have an extensive list here. Oh, so there's 20 of them. And I don't think. Oh, sorry, I didn't mute my phone.
B
Okay, somebody's alarming for some reason.
A
Barden's over 130, if that's beeping. Yep. Okay, so bell curve. And we're gonna get, we'll get a little description for it. So we have that on the list. So here's an easy one, like a flat and stable line that's in range, right? So a flat line that's going on forever. We need to know how to talk about it. So I think that one we can just call flatline, right?
B
We could call it the state of Ohio.
A
No, because it's flat. I don't know if people outside of the Midwest are gonna understand that or not.
B
Flat, flat.
A
So steady and in range with no real deviation. We'll call that a flat line.
B
Yes, fair. Okay, fair.
A
So now a post meal spike. A sharp rise after eating that will end with a sharp drop.
B
Okay, so it's almost like a mountain. It would be like a mountain peak almost because some mountain ranges just go up and kind of stay up. This is really a mountain peak.
A
Okay, so so we're going to call a post meal spike that drops back down again a mountain peak. All right, so we have a flat line, we have a bell curve. So we'll call it a bell. Right? We have a mountain peak. Now, a rise that dips down from insulin and then rises back up again from fat and protein.
B
So it rises up first, it comes down, goes back, and then it goes back up.
A
Camelback. Just camel, maybe.
B
Well, that really depends on what kind of camel you're talking about. Did you know that there are two kinds of camels?
A
There's a one hump.
B
There's the one hump, which is a dromedary.
A
Go ahead.
B
And the other hump, I can't remember the name of it, but it looks like if you turn a bee on its side, it's two humped. And there is a name for that type of camel too. So one hump is A dromedary. And the other one is be something or that is at our zoo. I should know this because my boys read it every time that we go to the zoo.
A
Wait, okay, I'm too humped. What's the camel called? Hold on a second.
B
What is a two humped camel called?
A
Yeah, that's what I'm trying to find out.
B
Bactrian. I knew I would remember it. Bactrian. Yeah. B, A, C, T, R, I, A N. Bactrian camel. It's a two humped camel.
A
There you go. Okay, well, we can't call it Bactrian because nobody's gonna know what that means.
B
They just call it the two humped.
A
So we're gonna call it a two hump. You get married and you'll have a two hump year.
B
There you go.
A
Two hump camel. Okay. Roller coaster. Big swings up and down. Like from chasing.
B
Yeah, right. Yeah.
A
But does roller coaster indicate to you sharp ups and downs or up, down, up, down more?
B
It could be. Honestly either. It could be, gosh, I see the mountain peak coming, so I'm going to get ahead of it, staying high. So now I really try to crush it and it's way too much. And now I come way down and oh gosh, I'm going to crash. And now I treat it and it goes way back up. That could be a little bit more pointy. Whereas something that is a little bit of a smoother roller coaster might be a different type of meal or know, whatever. So it could be either.
A
We can use roller coaster as a, as a general, but then when we talk about it, talk about it more like a peak or a gradual roller coaster. Like either like a sharp up, sharp down or gradual up, gradual down one way or the other. Up, down, up down, up, down forever is a roller coaster. I think of it as like you're chasing the blood sugar.
B
It is. And in two situations in the daytime, chasing blood sugar because of variables in the nighttime, if it's up, down, up, down, slow, something's wrong with your settings.
A
Okay, what about the one that kind of goes up? Stops. Goes up again, stops, keeps like it kind of like staircases and that. And you can see them go down too. Like what scenario?
B
It's almost like a pyramid.
A
Yeah, exactly. Like you're building a level on it.
B
Building a level up. Yeah.
A
Is that from. I guess. What could. That could be a lot of things. It could be, could be bad Basil. It could be an infusion site. That's not right. Right. It could be a little bit of a fat. You know, I've seen it sometimes with algorithms, you go up and you hit that kind of like you've missed it, and it boluses a little and you come down a little bit and then it brings you back up again. It's almost like up. Like an up down staircase. So there's a couple. All right, so there's six.
B
It's not a roller coaster. It is a continual climb that might have little plateaus.
A
Yep. As things are happening, it's the algorithm. Like, you go up, the algorithm thinks insulin, but it's never gonna give you enough. And so then you get a little stability for a while. It don't really go down and then it goes up again. So the more like staircasing up. And it can happen in the down, too.
B
And it might be around foods that do have. They might have a fair carb content to them, but they also might have a really good fat content. And so you may not have timed well enough to stop that initial rise up. And then as the insulin does get working along with the food, the fat at times is actually slowing down. What would otherwise be a pretty rapid rise, like the mountain peak effect. Right. Where you're just going to keep going up, whereas with fat included, you're going to get a little bit of an inching, inching. And eventually that might, even if you don't know well enough to cover proteins or fats, you might actually get that inch up and then it just plateaus at the top.
A
Yeah. Have you ever seen somebody do a cat ears on their dexcom?
B
Yeah.
A
They get a meal spike and a quick drop, but it doesn't go all the way back down. Then it sits a little stable higher, and then it happens again, like a quick spike, and then they really crush it the second time and it drop. And then they'll drop like a. They'll draw cat eyes on it or whiskers or something like that.
B
Yeah.
A
So we'll call that one. What do we call that one? Cat eyes. No, Cat head. No, we can't call it cat head.
B
Call it, I don't know, just Cat.
A
Cat. All right, for now, we'll call it cat. You know, it just occurred to me as I thought of that to Google it, and now I'm thinking we should probably just Google that with, like, maybe chat.
B
DPT could come up with a fancy name for all of these.
A
Well, we're going to have to come up with something here. All right. So then there's the dawn phenomenon kind of curve. Right. Like you're super flat overnight. And the morning comes, and then you're just on that, like, slow, steady climb that goes forever. I think of that one as the Price is Right game. The mountain climber game.
B
Oh, gosh. I haven't thought about the Price is Right in forever.
A
Thank you. I'm gonna call that one Climb like. Oh, we already used Mountain Peak. No, no one's gonna. No one's gonna know what that means.
B
No one's gonna know what that means.
A
So it's a slow. It's a slow gr. It's a. It's a. It's a very consistent and steady increase.
B
You call it the rock climber.
A
Yeah, that's more up. That's more straight up, though, right when you're climbing. I'm gonna write prices right here so we can figure out something more.
B
It's too bad we couldn't find a one to call Plinko. That was the one that I always like to watch.
A
There are some that look like that, but maybe we could call it the Bob Barker. Actually, people would.
B
Kind of funny.
A
Who's the other guy? Drew Carey.
B
Drew Carey.
A
Bob Garver's funnier. All right, hold on a second. Maybe we'll call that Bob Barker now.
B
Bob Barker. Oh, my gosh.
A
You don't forget to spay your. Neuter your animals. Remember, he would do that 100%. That little microphone. He lived a long time, by the.
B
Way, and he was on that show for a long time, too.
A
All right, so the next one I have here is like a sharp plunge for hypoglycemia. Like it just drops off a cliff. Right.
B
That's what I call it. Falling off a cliff. You call it cliff diving.
A
Okay, cliff diving. That's good. All right.
B
Because that's what I always. And I. You know, there are some scenarios that definitely go along with that. Right. One of that, I'm frequently use that term kind of for is when a sensor is being compressed, because it looks like the sensor data is just like, diving right off of where it was stable before, and it just takes a. An immediate, like, plunge. So that's one scenario of something like that. But another one would be obviously way too much insulin for a scenario that wasn't planned for. Right.
A
I think of them a little differently because the compression low, which I think is what you're describing, they look a little different to me because they're not a consistent fall. Like sometimes.
B
No, they're not a consistent line of dots.
A
Yeah. And sometimes you get, like, the disappearing. Like the. Like, it almost Goes to. Like it's there and then it's gone. And when it comes back, it's 15 points lower and Right. And then stable again. Like there's something about the compression low. If you're not actually falling during the low, every time it shows back up, it shows back stable. Does that make sense?
B
Yes.
A
Yeah. Yeah. I mean, I think compression low is just what we'll call that one.
B
Yes.
A
So cliff dive, compression low, flat but elevated. So you've woefully missed on a meal, probably. Right. And your basal's holding you steady, but it's holding you steady way too high forever. Like a plateau.
B
That would be a plateau.
A
Okay. All right, good.
B
Is there a name for those, like in the. Out in the, like the west, you know, where all of the.
A
So we're looking for a name for.
B
Those plateaus that are elevated above the actual ground. Almost like a mountain that goes up, but it doesn't have a peak top, it's just flat. I thought there was a name for those.
A
Cross your fingers that it's called. It says it's called a plateau. Oh, I said, what is a raised but flat natural structure called a plateau?
B
Okay.
A
Other natural words sometimes used, depending on nuance. Mesa.
B
Oh, a mesa. That's what I was saying.
A
Is that what you're thinking of? Yeah, Butte and tableland.
B
Oh, a butte. Yeah. There's Crested Butte, there's.
A
Yeah, but plateau is something. I think that's a word people know, right? Yeah. Okay.
B
Yes.
A
Because now we're doing this for the people listening, because we are, at some point Jenny and I are going to record short episodes where we take somebody's graph and talk through what we think happened to it. But it's of course going to be audio only and so you need to be able to visualize what the graph looks like. What the graph looks like. So that's why she and I are doing this now. Hopefully you'll find this interesting and then one day you'll hear a series of like. I don't know, I don't haven't figured out what to call that yet. But yeah, maybe graph breakdowns or something like that. Okay, let's see. So plateau and then meal stacking peaks. Multiple back to back spikes from closely spaced meal snacks. Today's episode is sponsored by Medtronic Diabetes, who is making life with diabetes easier with the MiniMed 780G system. The MiniMed 780G automated insulin delivery system anticipates, adjusts and corrects every five minutes. Real world results show people achieving up to 80% time and range with recommended settings without increasing lows, but of course individual results may vary. The 780G works around the clock so you can focus on what matters. Have you heard about Medtronic's Extended Infusion Set? It's the first and only infusion set labeled for up to a seven day wear. This feature is repeatedly asked for and Medtronic has delivered 97% of people using the 780G reported that they could manage their diabetes without major disruptions of sleep. They felt more free to eat what they wanted to, and they felt less stress with fewer alarms and alerts. You can't beat that. Learn more about how you can spend less time and effort managing your diabetes by visiting medtronicdiabetes.com juicebox the contour next Gen blood glucose meter is sponsoring this episode of the Juice Box podcast, and it's entirely possible that it is less expensive in cash than you're paying right now for your meter through your insurance company. That's right. If you go to my link contour next.com juicebox you're going to find links to Walmart, Amazon, Walgreens, CVS, Rite Aid, Kroger and Meijer.

Contournext.com juicebox and if you already have a contour meter and you're buying test strips, doing so through the Juice Box podcast link will help to support the show. So like, right, like the, like the we call them.
B
It would be almost like a mountain range.
A
Alpine.
B
Yeah, because it would almost be like you've gotten up to the peak of a mountain, but it just stays up there and keeps going up and down.
A
Yeah, it's like a lightning bolt moving up to the right so there's no backdrop. There's like spike little weight, spike little weight, spike little weight. So that happens. Can happen if you get behind one meal and then you start eating more and more meals or another course of something. Or something like that. Okay, so we can call that that. So what are we going to call that? Lightning bolt? What did I just say? Alpha?
B
I think lightning bolt is more of like a. Yeah.
A
Jagged.
B
I'm look, I'm thinking more of it goes up and then it's more of like a plateau with peak, peak, peak, peak, peak. Kind of along the way. So what did you called it?
A
Something Alpine.
B
Alpine.
A
There you go. Gentle rise or gentle fall across an entire day. I call that a drift.
B
Yeah.
A
Yeah. Okay. Is it a basal drift?
B
Depends on what you see in the data.
A
Just drift? Yeah. Okay. I dropped during activity and then a delayed spike hours later. Is that a thing you see a lot?
B
Yes. I mean, there are good reasons for it. I actually just got done talking with somebody about those issues. A name for it, though. I mean, to bring in relevance to description without an actual graph visual for people who are listening, it has to be a name that's centered around exercise. Right.
A
Activity drop.
B
Didn't plan.
A
Well, Jenny's like, I just interviewed a woman earlier today that when she was first diagnosed, somebody told her, when you go to have a baby one day, I need you to plan a year in advance. And then when, years later, when she went to have a baby, she followed those instructions. She started planning a year before she had her baby.
B
Good for her.
A
She said that? A combination of your book and my episodes about pregnancy. She had a very smooth pregnancy.
B
That's awesome. Yay.
A
But she planned ahead. And it made me think of that when you said didn't plan. I don't think we can call an activity drop.
B
No.
A
You up?
B
I was totally kidding.
A
Something about activity, exercise. That's going to take some. You know what we're going to do? We're going to take this list, and I'm going to take it online, and I am going to get people. Yeah. I'm going to get feedback because there's probably a thing people colloquially call this stuff, Right.
B
So that could be.
A
All right, predictable spike linked to menstrual cycle, puberty, stress, or cortisol. So hormonal. I don't know. That's still just a spike, right? Does that look.
B
It is, but if we have some data that we're talking about and we know it's relative to a hormonal change, it may make sense to call it hormones.
A
Okay. All right. Do you think it's a thing we'll see on a graph at some point? I mean, somebody's gonna say to me, this is my period. Right. And we're gonna have to be able to talk about it.
B
Yeah.
A
So, okay. All Right. So. Oh, why don't we call it a hormonal surge?
B
There you go. Great.
A
I like the way. The way surge sounds there. Compression low. We went over already a late night spike. So hours after a meal, a. I mean, you know, we're talking about like, you know, a pizza you ate at 10:30 or something like that. Then you get that kind of like. See, I prefer to call it.
B
Call it restaurant. Restaurant hit.
A
It's a fat rise in my mind.
B
Oftentimes it is. If again, we're basing this on all other things are tested and true. Right. And if they aren't, then go back to the drawing board and don't use this until you have settings that are pretty good. But for something like this. That's why I said restaurant, because it's often a fat hit that's very late.
A
There's another one that. The shape of it looks like a shark fin. So it's sort of like a. Like a quick spike and then a slow drift. Right. So you get the. I'm holding my hands up, no one listening, because this is going to be the problem. So you get that quick spike, but then more of an a frame, like drift away. So that shark fin. That one will be an easy one. Yeah, the zigzag. Have you ever seen a zigzag? Just like sawtooth. It just keeps going like that forever and ever, all day long.
B
Kind of like the roller coaster.
A
Yeah, I guess so. Right. Zigzag, roller coaster. All right.
B
They're kind of similar.
A
All right, I'm deleting that one. Boom. I'm very easy to get along with. That one's gone. Long stretch. A prolonged plateau. Plateau is a plateau. We don't need that listed twice. What about when two of the shapes come together? Because there's going to be repeatable stuff. I'm making this up. But after we do this for a while, what we're gonna see is that people come out of a roller coaster and go into a bell. Or like. Or, you know, people come out of a bell curve and into a. This. Like we need a word for the transition. What is it gonna be called when.
B
Two graphs are on the same day?
A
One turns into the next. Like, there's gonna be. There's a name for that transition there. The coupling of. Mm, that's harder. Maybe we're gonna have to workshop that. Maybe that'll come up naturally while we're having the conversation.
B
Yeah.
A
Okay.
B
I did think of something while you were just talking about that night rise. It could also be Relative to kid growth? Yeah, growth, because it's very common for kiddos who have especially younger kids who have early enough dinners, they're not eating at 8 or 9 o' clock at night. For the most part, they're eating a dinner at six, five, maybe six o' clock and then they end up going to bed and as soon as they fall asleep or their head hits the pillow, up their blood sugar goes. So that's definitely different than restaurant effect, but it's an age specific issue.
A
Growth hormone. It is. Describe it to me though. What's it look like visually?
B
Visually, it looks like they ate something and didn't bolus and literally had no insulin for it at all. They have a really nice smooth post dinner trucking along, really nice and stable into bedtime. And as soon as they fall asleep, up it goes. I see it too. In the afternoon for kiddos who still nap, we often will have some type of a setting that accommodates for an afternoon 2 or 3pm snack. Because if it's not covered up, their blood sugar goes because they fall asleep.
A
Is what usually happens a spike? Is it drastic?
B
Usually it's usually drastic. In fact, it's one of the most frequent things that I hear parents complain about. How do I get over? I can do the day, but this end of night thing that happens, I feel like I give three times the amount of insulin that I would normally give during the day and it still is way too high unchecked.
A
Does it go to a plateau at some point?
B
Very likely it would go to a plateau at some point, yes.
A
Okay.
B
But today's parents, really, they don't want that for their child. Wouldn't want that for myself or my child either. And so the plateau is hard to see unless you really tell somebody, hey, we have to watch for what is the rise? How can we average the rise? See how much you get before it actually stabilizes too high and then we can figure out a strategy for bolusing to prevent it.
A
Okay. I have a real feeling about how this is gonna go because, yeah, this is starting to make a little sense to me because using that was an example. Like somebody's going to show you that graph and the person is showing it to you does not know what's happening. Right. And so a person will come online and go, that looks like growth hormone to me and that'll be the end of it. But as you and I talk through each one of these shapes, because that's going to be the next thing, I'm going to send you all the Shapes. And then we're going to talk through the shapes.
B
Fabulous.
A
Yeah, it'll be fun.
B
Are you going to draw them yourself?
A
Oh, I hadn't thought about that. I'm going to. I'm hoping people will send me real graphs. Yeah. Like, once we get the. My goal here is to get down the naming structure a little bit and then have a good solid description of what that structure the shape is.
B
Sure.
A
And then have somebody say, oh, I have one of those. Here it is. And then now you and I have actual models to work with.
B
Awesome.
A
My idea here is to first talk through each shape individually in short episodes, and then after they're out, take people's graphs that they send in and just try to diagnose them without knowing anything about what they did. Right. Because I think, where did all this come from? This all came from. People send me a lot of graphs, but not usually a lot of context.
B
Right, right. Hey, what do I do here? Look at this graph. You're like, well, tell me what went into this day? Because that would help.
A
And in a perfect scenario, I'd like to know that too. Like, I think that's right. But I think that after years and years of looking at them, you can kind of infer.
B
You can kind of.
A
Yeah. I think what happened here might have been this. Right. We have this great argument online. I used to have this great argument with this woman in the Facebook group where I would always see a rise and then a plateau. And after hours the plateau is not touched by the Basil at all. There's some people. And then it comes down. Eventually there was these two arguments that would happen online. Like one person would be like, that's Basil. And the other person would be like, that's pre Bolas. And it is. If it is and it isn't. Anyway, it's. There's like this nuance there that I think is going to be interesting to talk through on all of these. So anyway, so we're going to. We're going to get the naming together, then we're going to break down what that, you know, what that naming exactly means.
B
Okay.
A
We'll get examples of them. You and I will record a short episode describing each shape and then we'll let people send in graphs that are like 12 hour, 6 hour, 24 hour graphs. And then we can describe to you as we're going, here's a 12 hour graph. It's a plateau that goes into a this, that goes into that. And then we'll talk through how we think it happened.
B
Yeah.
A
All Right.
B
That'd be great.
A
And then we'll start getting people who have the graphs with the information about the food. Then we can blind break them down and then layer over the information they said to see if we were right or wrong about what they did and where things happened. Sure. This is genius, Jenny.
B
Yay.
A
Yes. This is going to be real. Listen to me. This is not like.
B
Do you want to just step in and, like, record all of my conversations with people all day long? Because this is what I do.
A
Yeah, I know. I just. I thought to turn into a podcast.
B
No, it is a fantastic. Well, I think because it'll take very consistent scenarios that people see over and over and apply an idea for how to work it out.
A
I think so, too. I have been blocked, mentally blocked on this for years. This is obviously something that I've been thinking about for a long time. But I kept just saying, well, it's not a video podcast. If you can't see it, then what's the point? You're never gonna know. But I don't think maybe that's true. I think maybe there's a way to talk through it and describe it. Describe it. And then, you know, I have a website. I could say, like, look for this episode, the graphs on the episode. You can listen to it while you're staring at it if you want to. And if you don't want to. You know, again, I think the repetition of us talking about it. What am I talking about here? On a series, I'm talking about maybe by the time it's over. I don't know, 40 short episodes, like, spread out over a year. You listen to those for a year, you're probably. You'll know what you're doing by the time it's over. Yeah, that's all. Damn it. Yay. Yay. Yay. Yay.
B
Good. I. Good idea.
A
Was not all my idea. It's the thing that people have been foisting on me for a long time. I have thought it was a good idea. I did struggle with how it would work. Audio only. And then full respect to Steven, who was on an episode recently and just said, like, why don't you just give all the shapes names? And I was like, oh, well, that makes sense. We're going to have to break down. I assume we're going to be using the same. Probably less than 10 shapes, mostly when we're talking about stuff.
B
Well, I think also a lot of the other episodes that we've done together are a very good starting place for now, understanding how to See the shapes? We have lots about nutrition. We have lots about the effect of different foods and lots about insulin use and how to time things right. So this will now make a lot of sense if you've listened to those episodes as well.
A
Yeah.
B
I think you can kind of bring it all together.
A
This is all gonna culminate in the next couple of years with you, by the way. You have to continue to do this with me or you're stuck. You have to do this.
B
I'm stuck, yeah.
A
To me, this culminates with us re recording a Pro Tip series as if we've never done it before. Because I believe that who I am and who you are has been informed a lot by all the conversations that we've had and all the time and experiences we've had since then. I'm interested to see what another recording of the same topics would sound like. I think it's possible it would. I don't know.
B
Well, and how many years has it been since we did that? Because technology has also changed considerably.
A
I was thinking about this today, actually. Technology's changed. Aid systems are here. But in the end, whether you're on an aid system or you're not, the basis of what that Pro Tip series is about, still maintain it sticks. Correct. It's about timing, it's about amount. It's about using insulin in the right places.
B
It's about knowing your settings.
A
Yeah, it's almost turns the aid system into another variable. Because still in the end, your understanding of how insulin works is.
B
It's the foundation.
A
It's the foundation of the entire thing. Almost said plateau because now I've said it 17 times today, a word I have not said in years. I think that you and I might be able to put together like a pan ultimate kind of conversation that would going to end up encapsulating all the stuff you just talked about. Because nutrition, they might be a little longer. But listen, what are you guys busy with? Just listen to the podcast. It's free. You know what I mean?
B
Weed your garden and put the earbuds in.
A
You know, you're all not going to hire Jenny and I can't come to your house. So like, you have to figure this out on your own. Thank you very much. I appreciate it.
B
Of course. No, it's great. Thank you.
A

Episode #1651: CGM Graph Reading
Date: October 13, 2025
Host: Scott Benner
Guest: Jenny Smith
In this innovative episode, Scott Benner and diabetes educator Jenny Smith take on the creative challenge of giving memorable names to the various shapes and patterns seen on a Continuous Glucose Monitor (CGM) graph. Their goal is to establish a shared vocabulary for discussing these graphs in future audio-only episodes, empowering listeners to more intuitively understand and communicate about their blood sugar trends. Throughout, the conversation is engaging, playful, and deeply practical for people living with diabetes.
Together, Scott and Jenny brainstorm notable CGM data shapes, their typical causes, and what each might be called for clarity and relatability.
Bell Curve: Gentle rise, plateau, and gradual descent, ideally how post-meal blood sugar should look.
"It should look somewhat like a bell curve if people are familiar with that term."
— Jenny (02:24)
Flat Line: Stable, in-range reading with no significant deviation.
"So a flat line that's going on forever... steady and in range with no real deviation. We'll call that a flat line."
— Scott (03:36–03:49)
Mountain Peak: Sharp rise after eating, followed by a sharp drop (post-meal spike and return).
"A post-meal spike that drops back down again—a mountain peak."
— Scott (04:10)
Two Hump Camel: Rise, dip, then another rise (often from mixed macronutrient meals).
"So we're gonna call it a two hump."
— Scott (05:29)
Roller Coaster: Repeated sharp swings up and down, often due to "chasing" highs and lows with insulin/carbs.
"Up, down, up, down forever is a roller coaster. I think of it as like you're chasing the blood sugar."
— Scott (06:30–06:49)
Staircase: Stepwise increases (or decreases), resembling a staircase; may result from slow-acting food or algorithm micro-adjustment.
"More like staircasing up. And it can happen in the down, too."
— Scott (07:15–08:07)
Cat: Two meal spikes close together, with drops that don't return to baseline ("cat ears" or a "cat face" on the graph).
"They'll draw cat eyes on it or whiskers or something like that."
— Scott (08:54)
Price Is Right Climber/Bob Barker: Gradual, steady, slow climb, often overnight due to dawn phenomenon.
"I think of that one as the Price is Right game... the mountain climber game."
— Scott (09:57)
Cliff Dive: Rapid and dramatic drop, typical of sudden hypoglycemia or sensor compression.
"That's what I call it: falling off a cliff. You call it cliff diving."
— Jenny (11:10)
Compression Low: Unusual, abrupt, non-linear drops, often from sensor compression.
"Sometimes you get, like, the disappearing... Like, it's there and then it's gone. And when it comes back, it's 15 points lower and right. And then stable again."
— Scott (11:59–12:19)
Plateau: High but stable line—missed insulin for a meal, basal holds blood sugar at a too-high level.
"So you've woefully missed on a meal, probably. Right. And your basal's holding you steady but it's holding you steady way too high forever."
— Scott (12:25–12:41)
Alpine/Mountain Range: Multiple back-to-back spikes from meals or snacks (meal stacking), resembling a rugged range.
"Would be almost like a mountain range."
— Jenny (16:30)
Drift: Gentle, consistent rise or fall over hours, usually due to basal issues.
"Gentle rise or gentle fall across an entire day. I call that a drift."
— Scott (17:20)
Hormonal Surge: Predictable spike linked to hormones (puberty, stress, menstruation, cortisol).
"So, okay. All right. So. Oh, why don't we call it a hormonal surge?"
— Scott (19:41–19:46)
Fat Rise/Restaurant Hit: Late, sustained, and gradual high after a heavy, often fatty meal (such as pizza).
"I prefer to call it... it's a fat rise in my mind."
— Scott (20:08–20:10)
Shark Fin: Quick, sharp spike, then a prolonged slow return to baseline—a rapid high followed by a slow fall.
"The shape of it looks like a shark fin. So it's sort of like a... like a quick spike and then a slow drift."
— Scott (20:32)
"Usually it's drastic. In fact, it's one of the most frequent things that I hear parents complain about."
— Jenny (23:18)
On the Value of Landmark Naming:
"If we have some data that we're talking about and we know it's relative to a hormonal change, it may make sense to call it hormones."
— Jenny (19:21)
Why Audio-Only Works:
"I have been blocked, mentally blocked on this for years. This is obviously something that I've been thinking about for a long time. But I kept just saying, well, it's not a video podcast. If you can't see it, then what's the point? But I don't think maybe that's true. I think maybe there's a way to talk through it and describe it."
— Scott (27:45)
Describing Parental Challenges with Growth Hormone Spikes:
"Usually it's drastic. In fact, it's one of the most frequent things that I hear parents complain about. How do I get over... this end of night thing that happens?"
— Jenny (23:18)
On the Mission:
"We'll get examples of them. You and I will record a short episode describing each shape and then we'll let people send in graphs... and then we'll talk through how we think it happened."
— Scott (26:58)

Scott and Jenny’s tone is collaborative, warm, and accessible, laced with humor (“We can’t call it cat head!”), pop culture references (“Price is Right climber,” “Bob Barker”), and a focus on concrete, relatable analogies. This approach makes complex diabetes management concepts both understandable and memorable.
This episode provides a fun yet practical foundation for understanding and talking about CGM data without visuals. The lively naming process sets the stage for future podcast series, promising deep dives into real-world diabetes data, troubleshooting, and community engagement. Whether you’re a seasoned T1D veteran or new to CGM, this episode will likely reshape the way you think and talk about your numbers.
