My 16 year old son feels nauseous everyday and vomits about 3 times a week. Hes had tons of blood work, everything is fine except for elevated ALT of 86, which the docs are contributing to him being a over weight. He is 6 2 and 270 with a large football player frame. Im at a loss. Any additional insite would be great. PMH: type 2 diabetes, Vitamin D deficiency , IBS. MEDS: Omeprazole 40mg QD, Vitamin D 2,000 units daily, Levbid prn, and Zantac prn
