“Gastroparesis is a condition that affects the normal spontaneous movement of the muscles (motility) in your stomach. Ordinarily, strong muscular contractions propel food through your digestive tract. But if you have gastroparesis, your stomach’s motility is slowed down or doesn’t work at all, preventing your stomach from emptying properly.”
