Motility disorders are conditions that affect the movement of muscles in the digestive tract, leading to difficulties in swallowing, digestion, and bowel movements. These disorders can result from various factors, including nerve damage, muscle weakness, or structural abnormalities. Common examples include gastroparesis, where the stomach takes too long to empty, and achalasia, which affects the esophagus. Symptoms of motility disorders may include nausea, vomiting, bloating, constipation, or diarrhea. Diagnosis often involves tests like manometry to measure muscle contractions or imaging studies to visualize the digestive system. Treatment options vary and may include dietary changes, medications, or surgery.
