I have been having chronic diarrhea/floating stools, for a while now; but one thing to take notice of is that I have been gaining weight/muscle. Since I started having chronic diarrhea I weighed 155-160 and now I have gained to 180. Does that mean I can rule out malabsorption as the cause?
Welcome to the gastroenterology community! You can't rule out malabsorption just because you aren't looking weight, however it makes it more unlikely. Have you seen a doctor about this?
