The U.S. Food and Drug Administration approved the Gastric Emptying Breath Test (GEBT), a new non-invasive test for the treatment of delayed gastric emptying, known as gastroparesis. Gastroparesis is a condition in which your stomach cannot empty itself of food in a normal fashion. It is caused by damage to the vagus nerve, which regulates the digestive system. A damaged vagus nerve prevents the muscles in the stomach and intestine from functioning, preventing food from moving through the digestive system properly. If this left untreated, gastroparesis can lead to problems such as severe dehydration due to persistent vomiting, difficulty managing blood sugar levels in people with diabetes, and malnutrition due to poor absorption of nutrients or a low caloric intake.
