Brief Answer: You need to make a direct abdominal radiography and to see a surgeon. Detailed Answer: Hello, Thank you for using HCM. I want to help you understand the cause of your symptoms , but is important for me to know why do you think you have no bowel movement . It is just because you don t feel them moving, or you went to a doctor who visited you ? Did you have vomiting during these 3 days ? Usually the first 24 hours after the surgery , has no bowel movements because of the anesthesia and after that the peristaltic is reset. Which means that the absence of bowel movement 2 weeks later , has to be further evaluated by doing a direct abdominal radiography and then a surgical consult. Regarding the heart burn, it happens because the bowels are filled with gas and fecal mass , which distend the abdomen and elevate the diaphragm causing the return of the food in esophagus. You can take 20 mg of omeprazole every morning. Try to eat small portion of food. Don t lye down immediately after eating. Avoiding spicy,acidic,fried foods, mint, tomatoes, onion, caffeine. BUT the most important think is to a direct abdominal radiography and then a surgical consult. Hope this is helpful. Let me know if you need more clarifications. Otherwise please close and rate the answer. Kind Regards, Dr. Juarda
