Hi Verma Thanks for posting on HCM Abdominal bloating, indigestion and heartburn could be cause by the following medical conditions: -Swallowing air -Constipation -Gastroesophageal reflux (GERD) -Irritable bowel syndrome -Lactose intolerance and problems digesting other foods -Overeating -Small bowel bacterial overgrowth -Weight gain -Ascites and tumors -Celiac disease -Dumping syndrome -Ovarian cancer -Problems with the pancreas not producing enough digestive enzymes I will suggest you try the following: *continue with pan- D or any other antisecretory *An antacis like maalox *Simethicone tablets may help with gas *Avoid chewing gum or carbonated drinks *Avoid foods that can produce gas *Eat at regular intervals and not too quickly *Avoid smoking *Take enough fluids(water) and avoid much fibers as may make your symptoms worse *Reduce the intake of milk and other dairy products that contain lactose If these measure do not help, you see the Doctor for examination and investigation.In this case, you will need tests like a stool exam, abdominal ultrasound, H pylori test, pancreatic function test... Hope this will help Wish you good health
