Has anyone experienced a foul taste in mouth? I 've had this taste now for over 1 year..I've been to GI, Eye, ear, nose, throat specialist, Dentist, Gyno to rule out menopause issues,natural doctor for vitamin defiency I've had every GI test to rule out many things with all normal results.Endoscopy, colonoscopy, Gastric emptying , HP PROBE test, Ruled out acid reflux, normal digestion and cat scans and tests for H pylori and celiac. The only test that came out positive is Hydrogen Breath Test. I am Lactose intolerant. I do have bloating but no other bathroom issues.I thought we found the answer ,But with Dairyfree diet over a month still have nasty taste all the time..My gastro doctor is puzzled. I still have energy but get tired very quickly. Really try to eat healthy and drink lots of water. I am in need of some advice. Other symptoms are flu-like flashes not like other flashes I have had. ((I'm in menopause so don't know if their hot flashes) Seem tired more and I do get very pale and my husband can tell by my complexion when my taste is very bad. I tried to pinpoint it with diet but nothing is coming up. Help!!!
