I am currently suffering from constant hunger even after i have eaten and seem to have small white bits in stool. worried as to what this could mean?

May be unrelated but: ...lots possible. Epigastric burning & hunger pain after meals raises probability of gastritis &ulcers. Stop any non-prescribed nsaid's or aspirin; cut out tobacco &alcohol; consider starting an acid reducer medication. Seek emergency care if lightheaded, worsening symptoms, vomiting coffee ground material or passing black stool or blood. Pancreatitis & biliary dyspepsia can present this way.
