Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain chronic burping or belching occurs due to excess formation of intestinal gas ad can occur commonly due to causes like indigestion, Gastroenteritis or stomach infection, taking heavy meals, taking excess of frizzy or carbonated drinks, smoking, eating too fast can lead to swallowing of more air, lactose intolerance, irritable bowel syndrome etc.. I would suggest you to consult a Gastroenterologist and get evaluated and a thorough clinical evaluation and investigations like Colonoscopy, Ultrasound and blood test can help in diagnosis and treatment can be planned accordingly.. You can be advised antibiotics if there is infection, antacids, Simethicone that helps in reducing excess gas,taking light meals, doing moderate workout, avoid fatty foods and carbonated drinks. Drink plenty of warm water.. Take walk after meals. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
