Poop floats primarily due to excess gas trapped in the stool or because of a higher fat content in the stool. The gas may come from swallowing air, eating certain foods that produce gas, or fiber breakdown in the colon, which releases gas that gets trapped in the stool making it buoyant. Foods high in fiber, like beans, cruciferous vegetables, fruits, and whole grains, can cause this effect. In some cases, floating poop may indicate a health issue related to fat malabsorption, such as steatorrhea, where excess fat remains in the stool due to problems digesting or absorbing fat properly. This can occur with conditions affecting the pancreas, celiac disease, or infections that impair nutrient absorption. Fatty stools also tend to be pale, large, greasy, and have a strong odor. Generally, floating poop that occurs occasionally due to diet is not a cause for alarm. If floating stools are persistent, accompanied by other symptoms, or appear greasy and foul-smelling, it is advisable to consult a healthcare provider to rule out malabsorption or infections.
