I have gallbladder disease with an er of 14%. i occasionally have nausea and vomiting. my concern is that i always feel hungry and the need to eat constantly. hair loss as well. thyroid checked out fine. could it be from the gallbladder?

Gall bladder: Hair loss and constant hunger are not symptoms of gall bladder disease. Since your thyroid tests are normal other tests such as blood sugar, iron level and pregnancy testing(unless this isn't a possibility)can be done. A gastroenterologist should be consulted to evaluate you for other gi issues although gall bladder dysfunction may explain periodic nausea and vomiting.

Unlikely: Symptoms that you have described can be due to other causes, and what comes to my mind is that it might be caused by medications, so are you on any treatment in particular? If so you might need to check about that. Also... stress might be another cause of hair loss and eating constantly

Possibly: however I also suggest a pancreatic ultrasound, blood chemistires including Fasting blood sugar, A1c level, thyroid function and pancreatic enzymes coupled with a comprehensive physical exan
