GI motility is defined by the movements of the digestive system, and the transit of the contents within it. When nerves or muscles in any portion of the digestive tract do not function with their normal strength and coordination, a person develops symptoms related to motility problems.
There are a variety of motility disorders that can affect the GI tract from the very top (esophagus) to the very bottom (colon and rectum).
Each part of the GI tract – esophagus, stomach, small intestine, and large intestine – has a unique function to perform in digestion, and each has a distinct type of motility and sensation. When motility or sensations are not appropriate for performing this function, symptoms occur.
