Understanding the Signs of Dehydration in Elderly Individuals

AI Thread Summary
An elderly individual refusing to drink fluids, despite maintaining a regular food intake, raises concerns about hydration and overall health. The discussion highlights a case where an elderly father, who has a history of low fluid intake, is now on multiple medications that require adequate hydration for proper functioning. Family members express frustration as he only consumes sweet beverages, showing a reluctance to drink water, tea, or juice without prompting. This behavior has worsened with age, leading to speculation among family members about his intentions regarding life and health. While some suggest he may be intentionally refusing fluids as a sign of wanting to die, others argue that his consistent food intake contradicts this theory. The situation underscores the importance of addressing hydration needs in the elderly, especially those on medication, and the potential implications of their fluid intake habits on health.

If an elderly person refuses to drink much fluid (although, still eating regular proportions of food - relative to age), is that a sign of something wrong/dying?

I cannot understand why my father has stopped drinking fluids. He's never drank much fluids to begin with (throughout his life), but given he's on multiple meds now, he SHOULD/NEEDs TO drink a lot of water to have enough fluids to break down those pills. Despite his doctor telling him he needs to drink more water (ongoing for years), he still doesn't get enough.

He does eat a lot of fruit, which has water. But, he drinks almost nothing without being begged to/yelled at by my mother, sister, and I. If one of us is not around, he will not drink anything when he eats. There is an exception. He will drink soda or something sweet. He can drink a full glass or more of sweet stuff, but that is almost always bad for him. Water...tea...juice...he won't drink (it's practically by forced the family members have to yell at him to do and even then he'll refuse at times).

It did not seem to be as bad years ago, but seems to have gotten very bad with age. My siblings have suggested my dad wants to die and is purposely refusing water/fluids. He has declined and has multiple heath issues now. I know his life is not the same. He is very apathetic. However, I don't buy their reasoning entirely (though I think it's possible). The primary reason is that my dad eats the same. If he wanted to die, I think he'd stop eating too. Also, he will eat or drink a lot if it's sweet stuff, so there's that too.

I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
