I’ve been food allergy tested and also tested for SIBO and H pylori 2-3 x . Plus many, many ,many other tests . Burping is same in day or night . I didn’t start any new meds when this started in 2013 . My gut is always churning and I do have IBS symptoms for years . The 1000’s of deep wet belching is so horrible. I can’t eat anything that doesn’t upset my gut and intestines. I take something to help sleep but as soon as my eyes open it starts so up badly . I’ve tried everything holistic including 3 sessions of hypnosis therapy ( which I found out , I can’t be hypnotized).!! I sure hope this Dr. thinks outside the box and can help me get my life back . Thanks @hopeful33250 .
