Dr. Amy Nett: If I’m concerned about decreased gut motility, I’m often looking for constipation. This is often people who are going to tell me they either feel like their food is just sitting in their stomach, so they often feel like things aren’t moving, or they’re seeing food that they ate two days ago not being passed in the stool, for longer than we would expect. Often I’m thinking about constipation as an indication of decreased gut motility or what the patients are telling me. They can often tell you, “My GI tract just isn’t moving as I would expect it to,” and often it’s a change from what used to be normal for them.
