Occasional floating stool, slowly sinks. some air bubbles. stool is brown soft and formed. normal colonoscopy, ct scan and stool tests. should i worry?

Got symptoms?: Why colonoscopy at age 34? Checked diet, possible small bowel issues? No alarm symptoms based on what you wrote in. Talk with your doc.

Don't worry: Floating stools are caused by foods that you eat that cause gas production or could be from malabsorption/ not absorbing essential nutrients causing them to be passed in the stool and making the stool float . I'll be concerned if there are other symptoms like weight loss, abdominal pain, loss of appetite, blood in the stool etc then go see your dr
