I have had chronic belching and bloating for about 12 weeks. Sometimes I have days, when I belch in every 5 seconds without exadderating. I live a healthy lifestyle. Only issue is low vitamin D count. Tested negative for H.Pylori, had urine/stool tests, wide variety of blood tests, ultrasound and endoscopy. I'm still waiting for results on biopsy report. Family physican has never witnessed such severe symptoms and my gastroenterologist has no idea what could cause this anymore.
