My names Austin and I m 17 years old. Recently I ve been extremely dizzy/light headed and it s been going on for a few months now. Everyday all day it s like this. I ve been to the hospital multiple times but everything came up negative. Diabetes, Gallbladder, Vertigo, Inner ear infection, abscess tooth, Thyroid, they all came up negative. Aswell I m bloated all the time, after I eat anything. As well constipated. With that gluten intolerance came up negative, lactose intolerance came up negative, It s extremely frustrating and really starting to mess up my personal life, can anyone help? At least give a few possible situations it might be?
