reasons for weight loss in old age - #19300

I am worried about my dad. He’s 78 and has lost a noticeable amount of weight over the last few months and nobody seems to really know why. I mean, one day he was eating normally, and the next it felt like he was just picking at his food. My mom, she thinks it's just because he’s not as active anymore, but I feel like there has to be more to it. He isn’t sick or anything that we know of, and we’ve been to the doctor a few times already. They checked for some common stuff but say he’s okay… but what could be the reasons for weight loss in old age like this? He says he’s not really feeling any pain or anything, but he's kinda down about it. I heard that sometimes it could be something serious like depression or even hormonal changes, but then I also think maybe it's just the aging process, you know? I don't want to jump to conclusions but I keep reading about the different reasons for weight loss in old age and it's freaking me out. Just yesterday he walked past the fridge and I could see his ribs. It feels like he’s got no appetite, but he says he’s not even hungry, and that’s not him at all! Any thoughts or advice on what could be going on? What are the best reasons for weight loss in old age—like, what should we be looking into next?

In older adults, there can indeed be several reasons for unexplained weight loss. First, it’s good that you’ve already engaged with a healthcare professional, yet symptoms like these sometimes need further investigating. You mentioned that your dad’s appetite has diminished; one possible explanation could be taste and smell reductions which often happen with advancing age. This can make food less appealing. Sometimes, dental issues can make eating physically uncomfortable or difficult. Depression, as you mentioned, is another significant concern; it can definitely impact appetite and interest in eating. Moreover, conditions like cachexia related to chronic illnesses, though less visible early on, can lead to weight loss.

Metabolic or endocrine issues are also worth considering, such as hyperthyroidism which can increase metabolism and lead to weight loss despite normal or reduced food intake. Checking thyroid function tests could be wise. Malabsorption syndromes, possibly owing to intestinal issues, could lead to inadequate nutrient absorption – look for changes in bowel habits, bloating, or discomfort as clues. Furthermore, some medications may cause appetite changes or gastrointestinal side effects, and you might want to review them with his doctor. More serious considerations could include occult malignancies (like cancer), although you’d usually see additional red flags like pain or fatigue.

Also, it’s important to observe other lifestyle changes, such as social or environmental factors that might be contributing. Encourage wholesome eating habits, ensure regular small meals, and explore high-calorie, nutritious options if his appetite is down. Keeping regular follow-ups with his doctor is critical, and perhaps discussing the need for a more comprehensive assessment or referral to a specialist like a geriatrician or dietitian might yield additional insights. Testing tailored to specific suspected causes could give more direction. It’s understandably concerning, but gradual, persistent weight loss in seniors should definitely be monitored closely, and getting to the root of it early can make a real difference.
