An uncle has suddenly got very thin. He tells me he is eating normally and has no loss of appetite. He does have diabetes and takes tablets for that. The only other symptom is dizziness - especially when he stands up from sitting or lying down. He has had four check-ups but none have identified what the cause could be. Anyone any ideas? Thanks.
Unexplained weight loss is very concerning and as Mamya says bloods would be the first thing to look at, followed by imaging if the bloods throw up anything concerning.
If it was a relative of mine, I would be pushing for closer inspection.
How old is your uncle? What does he actually eat? Is he Type 1 or Type 2 diabetic? I ask this because eating 'normally' does not necessarily mean eating healthy. Ask him to do a food diary and make sure he is having a balanced diet with plenty of protein and perhaps up his dairy products. Its not unusual for elderly people to drop weight, especially if they are not eating enough proteins. On the bright side, if he's had 4 check-ups already its likely to be anything serious.
