Hello dear, The sensation of burping can be attributed to accumulation of gas in the stomach, secondary to incomplete evacuation of bowel. Considering the problem that you are facing regarding bowel movement, laxatives are helpful for providing temporary relief. The symptoms as mentioned in your post can either be due to functional reason (decreased gastric motility) or any pathology (like obstruction) in the Gastrointestinal tract. Kindly consult a Gastroenterologist & get a proper clinical examination done to detect any pathological cause for the symptoms. Investigations like Ultrasound scan of abdomen, contrast studies & Colonoscopy will be helpful. Permanent relief from your symptoms will be obtained once the underlying cause is corrected. You can also use Isabgol husk at night time. It will help in clearing of bowel in the morning. Wishing you a Good Health Take care.
