How is gastroparesis diagnosed?
Your doctor will go over your symptoms and medical history with you. He or she will also give you a physical examination and may order certain blood tests, including blood sugar levels.
Other tests that are used to diagnose gastroparesis include:
- 4-hour solid gastric emptying study. This is a test to determine the time is takes a meal to move through a person’s stomach. A technologist will take you to a room and give you a meal to eat that is tagged with a radioactive isotope. After you eat this meal, a one-minute image of your stomach will be taken. You will be allowed to leave the department, but you must return in 1, 2, and 4 hours.
- SmartPill. This is a capsule that contains a small electronic device. You swallow the capsule, and as it moves through your digestive tract, it sends information to a receiver you are wearing on how quickly food is traveling through the digestive tract.
