Simethicone products are not helping. There is no diarrhea or constipation or belching. Stools are not abnormal in color. I have no history of intestinal disorder, gall bladder or pancreas trouble. First, cut out all milk products.
Lactose intolerance is very common and occasionally is only seen in later ages.
This would require antibiotics. So, cut out the dairy products. If you're not better check with your doctor. The amount of flatus that I pass has increased significantly. I have no health problems and no other symptoms.
