Ok --Poor appetite can be due to the lack of bile acid mixing with food which gallbladder facilitates when present.
Also you may have pancreatitis or pancreatic digestive enzyme insufficiency.
Hence blood tests like liver function test, amylase, and an abdominal scan should be performed.
if these tests are normal, then your problem lies in chemical imbalance in the brain.
This can be treated with a medication called Mirtazapine 15 mg daily at bedtime.
Mirtazapine helps with sleep as well as improves your appetite and weight gain.
Please discuss with your doctor.
