why does your bowel sink to the bottom
Stool sinks or floats depending on how much air (gas) it contains. If there is little or no gas trapped in the stool, it sinks. If it contains a lot of tiny gas bubbles, it floats. The amount of gas in your stool is affected by the foods you eat, the types of bacteria that normally live in your gut, and how long it takes food to move through your system on its journey into the toilet bowl.
