I've had these exact symptoms for five years now. Bloating was severe and the burps were short and quick and could last for hours. Now, the bloating is still here but the burps are long and gurglee. My frienRAB say it's my yoga sound. At first my physician thought it was Gerd and prescribed me medicine for a month and it made my symptoms worse! I've had every test known including blood work, a cat scan, 2 endoscopies to test for gerd, gastritis and parasites... all test were negative. Then I had 2 ultra sounRAB, a Hydrogen breath scan, a hida scan I and II, and a Nuclear Gastric Emptying Scan. I've paid to see an air swallowing specialist who said I was NOT swallowing air. I saw a deep relaxation expert who helped me relax with deep belly breathing, I still had the symptoms. I live a great life and am very fortunate to have very little stress. I take yoga now about 3 times a week and have for 3 years. I was diagnosed with IBS (Irritable Bowel Syndrome) this basically means they don't know what's wrong with me. They prescribed me a medicine to calm my stomach and I took it for two years but it still did not change so I quit. I've spent money on acupuncture and it was nice but not the answer. I've spent money on a homeopathic doctor who prescribed a cleanse that made matters much worse. I've had 3 different GI docs and two different Physicians who are baffled. Now, I get regular check-ups, eat a Paleo diet (little to no carbs), see a chiropractor and massage therapist twice a month (this helps to release a lot of burps) and live with this unknown bloat and burp issue. If anyone is diagnosed with a proper diagnosis, please let us all know. All my best.
