Yeah, sure. So if I'm kind of trying to apply my geriatric 5 Ms. To unintentional weight loss, I'm going to be tailoring everything a little bit to that. So within multi complexity that's kind of typically where we think about like what are people's medical problems, what are their symptoms? So this is where I'll think about like organic causes of weight loss. So that could be either, you know, a known disease that someone has that could be worsening. So let's say they have COPD and it's becoming end stage, they have heart failure, it's becoming end stage and they're kind of in a inflammatory cachexia state. Or it could be a new disease that, you know, they've developed and we haven't yet diagnosed like a new cancer or malabsorptive issue and other other inflammatory diseases, things like that. And I think within this category, I also like to think about symptoms that older adults tend to have that we're maybe not as good about usually asking in our review of systems, even though we probably should be better at them still, myself included. And that especially relevant for here is things like visual deficits and also dental issues, which can both affect, you know, appetite, eating and weight loss. And this is a, I mean this is a pretty big bucket, you know, for unintentional weight loss. If you look at review articles for causes of unintentional weight loss, organic causes are going to be a pretty, pretty high up there. Malignancy being a common one and then non malignant GI diseases being another common one. So moving on to the other M's because I think that's the important thing too. Sometimes we just think about the organic cause and then we forget to look at other potential things that might be happening within the mind. M I'll think about things like depression or dementia. This is another very common cause that's cited in Review articles It is important to note that I think dementia can affect weight loss in a few different ways. I feel like typically we think about kind of very advanced dementia where someone has dysphagia, maybe they've forgotten how to kind of mechanically swallow, so they're pocketing food. They like physically can't feed themselves at all. Maybe they've developed pressure wounds and have an inflammatory state that's contributing. So I feel like that's kind of what classically we might think about with dementia and weight loss, like kind of that advanced situation. But I've definitely seen folks who've had weight loss associated with earlier stages of dementia too, especially if there are associated neuropsych symptoms. Like if someone has maybe mild dementia, but they have kind of a neuropsychiatric symptom of apathy, that can definitely affect people's appetite. If they have paranoia, that can affect their eating. I've definitely seen patients who have paranoia that their food has been poisoned by their family or things like that and they won't eat. If someone has developed wandering and they're, you know, walking a lot more than usual, that can affect their energy expenditure and can cause weight loss. Someone who maybe doesn't have cognitive skills to put together a meal anymore, there's basically, you know, a million ways you could potentially slice it. Even in those kind of more mild, moderate stages. And then in the mobility M I think about activities of daily living and especially those that affect eating. So, for instance, how are people shopping and getting their groceries? How are they actually getting to the store? Like, what's their transportation situation? Are they having barriers there? How are they cooking? Are they able to cook? How are they physically feeding themselves? And then also within this, I think about kind of physical function, activity level, you know, if someone is maybe not as active as they used to be and losing muscle mass, that can kind of like tie into the sarcopenia weight loss picture in medications that M this is such an important M I think pretty much any new symptom or medical problem in an older adult, you really have to go through the meds with a fine tooth comb. There's a great table in American Academy of Family Physicians. Hopefully I got that acronym right in one of their review articles on this topic that goes through a list of meds that cause issues with, with taste, appetite, dry mouth, GI symptoms like nausea. And it's actually like, when I went through it for the first time, I was really surprised. There were a lot of meds on there that were very common that I never would have thought had GI side effects. And I think the other thing kind of along with meds and their side effects is even if someone's been on the medication for a long time and they've been tolerating it before, as people age, the way that their body processes medications may change as well. Maybe they're on another new med that's causing a drug drug interaction. So they could be developing side effects that they hadn't had before. So it's still, you know, even if it's not a completely new medication, still something to think about.
