I am 51 year old male and am suffering unexplained weight loss and sudden loss of appetite?

I am 51 year old male and am suffering unexplained weight loss and sudden loss of appetite?

Go see your doctor!: Unexplained weight loss +/- loss of appetite needs to be evaluated. In this age group, we start worrying about colon cancer. Upper endoscopy to investigate stomach (for possible cause of loss of appetite) can be easily done at same time as colonoscopy (screening for colon cancer). Your family doctor can refer you to gastroenterologist for testing after checking for hyperthyroidism. Good luck!

Sudden loss of appetite. No other symptoms. Anxiety/depression has been under control for 3 years with 10mg Prozac (fluoxetine) rx. Could it be a new side effect?

Not likely: Nothing is impossible w/ side effects for psychotropics, but not likely. However, you might be ready to try to taper off Prozac (fluoxetine). I hate the idea of forever for a drug like that. If you've not done some therapy, you might want to try a bit to feel secure as you get off the meds. Best!
