Gastric Emptying Study: A Comprehensive Guide
Introduction
A gastric emptying study (GES) is a medical test that measures how quickly your stomach empties its contents. It is used to diagnose gastroparesis, a condition in which the stomach takes too long to empty. GES can also be used to evaluate the effects of certain medications or surgical procedures on gastric emptying.How is a Gastric Emptying Study Performed?
A GES is typically performed in an outpatient setting. You will be asked to drink a liquid meal that contains a radioactive tracer. The tracer allows doctors to track the movement of the meal through your stomach and small intestine. You will then lie down under a gamma camera, which will take pictures of your stomach and small intestine to measure how quickly the meal is emptying.What are the Benefits of a Gastric Emptying Study?
A GES can help your doctor diagnose gastroparesis and other conditions that affect gastric emptying. It can also help your doctor evaluate the effects of certain medications or surgical procedures on gastric emptying.What are the Risks of a Gastric Emptying Study?
A GES is a safe procedure, but there are some potential risks. These risks include: * Radiation exposure: The radioactive tracer used in a GES exposes you to a small amount of radiation. However, the amount of radiation is very low and is not harmful. * Allergic reaction: Some people may be allergic to the radioactive tracer used in a GES. If you have any allergies, be sure to tell your doctor before the procedure. * Nausea and vomiting: A GES may cause nausea and vomiting. If you experience these symptoms, be sure to tell your doctor.What Can I Expect During a Gastric Emptying Study?
Before the gastric emptying study, you will be asked to fast for 8 hours. You will also be asked to avoid smoking and drinking alcohol for 24 hours before the study. On the day of the study, you will be asked to drink a liquid meal that contains a radioactive tracer. You will then lie down under a gamma camera, which will take pictures of your stomach and small intestine to measure how quickly the meal is emptying. The study usually takes about 4 hours. You will be able to go home after the study is complete.What are the Normal Results of a Gastric Emptying Study?
The normal results of a GES vary depending on the type of meal that is consumed. However, in general, the stomach should empty about 50% of its contents within 2 hours and 90% of its contents within 4 hours.What are the Abnormal Results of a Gastric Emptying Study?
Abnormal results of a GES may indicate gastroparesis or other conditions that affect gastric emptying. * Gastroparesis is a condition in which the stomach takes too long to empty. Symptoms of gastroparesis include nausea, vomiting, abdominal pain, and bloating. * Other conditions that can affect gastric emptying include diabetes, scleroderma, and Parkinsons disease.How is Gastroparesis Treated?
There is no cure for gastroparesis, but there are treatments that can help to relieve symptoms. These treatments include: * Medications: Medications can help to improve gastric emptying and relieve symptoms of nausea and vomiting. * Diet: Eating a healthy diet can help to improve gastric emptying. A healthy diet includes plenty of fruits, vegetables, and whole grains. * Exercise: Exercise can help to improve gastric emptying. Regular exercise can also help to reduce stress, which can worsen gastroparesis symptoms.Conclusion
A gastric emptying study is a safe and effective way to diagnose gastroparesis and other conditions that affect gastric emptying. If you are experiencing symptoms of gastroparesis, talk to your doctor about whether a GES is right for you.Gastric Emptying Study CPT
