Hi. Thanks for your query and an elucidate history about your complaints of headache, dizziness, nausea and malaise; and hyperthyroidism with overweight, type II diabetes, gall bladder removal, raised liver enzymes and now worried about abdominal pain and diarrhea. With the multiple problems and contradictory findings like overweight in spite of hyperthyroidism indicated me for a rare problem that has to be researched and found out or ruled out. I would advise you the following: -Get an opinion of an Endocrinologist to rule out the possibility of hormonal syndrome of MEN I and MEN II, where you get such pictures. You will need MRIs and CT scans as an investigations. The pain in the abdomen with diarrhea can be due to uncontrolled or not so well controlled Hyperthyroidism. It is possible that once the thyroid is under control as well as you diabetes and obesity, everything is fine. You can also consult a center dealing with Obesity and Metabolic surgery for medical management and / or surgical management that all your problems will be under control.
