My husband eats, but why is he losing weight?

It could be a number of conditions/ailments. My Dad's had Parkinson's for years and went from 225 to 125 lbs over that period. He was a gooc eater too until the last month or so. Have worked with elderly folks nearing end of life before and am familiar with declining appetite and what that means.

My point for you is, follow the advice of others here and contact your husband's physician .. soon.

It could be cancer.

Why don't you contact his doctor?

How old is he?

Does he have an existing health condition?

How much and what is he actually eating?

Your question lacks too much detail for any real suggestions, but your first act should be to contact his doctor.

Have you taken him to the doctor? How long has this been happening? Do you have any ideas of why?
