How do internal factors affect external symptoms? could imbalanced colon show as red nose? bloating, irregular movements only colon symptoms-no pain

= A Dx of exclusion: When a GI problem is labelled "functional" it means inflammation, infection, & ischemic pathology, as well as motility disorders have been ruled out. Ruled in are conditions that alter how the gut "senses" pain, distension, & the movement of food or residue.
