Floating stools can be a result of two conditions-steatorrhea which is the inability to digest fat as a result of a deficiency in the digestive enzymes known as Exocrine Pancreas Insufficiency (EPI). EPI can have overt symptoms indicating the need for Pancreatic Enzymes Replacement Therapy. When more subtle such as just floating stool, the fecal elastase test is performed to determine if the output of digestive enzymes from the pancreas is sufficient. A value over 200 indicates normal. A value of 100-200 is moderate impairment and under 100 indicates significant impairment. In the latter two situations, a pancrealipase will provide supplemental lipase enzyme.

Another cause is a decrease in bile salts which are stored in the gall bladder. When a fatty meal is consumed, a hormones for the intestine are involved with signaling the pancreas to produce and secrete more enzyme and the gall bladder undergoes contractions to inject bile through a sphincter where the common bile duct connects to the intestine. Bile is needed to emulsifynfats to make them easier to digest.

The third cause is eating a diet of high fiber vegetables and fruits that are difficult to digest and result in the production of excess gas that is mixed with the stool making it less dense and therefore floats. Hard to digest vegetables such as corn, peas, broccoli, cabbage, Brussels sprouts to name a few are composed of complex carbohydrates called oligosaccharides. The human pancreas does not produce the enzyme alpha-d-galactosidase which is specific to digesting oligosaccharides. These vegetables remain largely undigested as they move through the intestine mixing with intestinal bacteria, fermenting, and producing excessive gas. To digest these vegetables, the OTC product Beano is the enzyme alpha-d-galactosidase. It will digest the oligosaccharides of the vegetables and prevent the gas from forming. Pancrealipase does not contain alpha-d-galactosidase in the blend of enzymes, so taking a product like Creon or Zenpep will not digest foods comprised of oligosaccharides.

Products like Gas-X and Phazyme contain simethicone. While Beano works proactively on the source material of the gas, simethicone is more of a reactive measure for gas already produced. The objective is being proactive in preventing the gas formation which is what Beano does. Either of the simethicone containing products can be taken with Beano. There is no known interactions.
