A gastric emptying study is a diagnostic procedure used to measure the rate at which food moves from the stomach into the small intestine. This test is primarily used to evaluate patients experiencing symptoms such as nausea, vomiting, bloating, and abdominal pain, which may indicate delayed gastric emptying, also known as gastroparesis. The procedure involves the patient consuming a meal containing a small amount of radioactive material, which is then tracked using a specialized camera to monitor food movement through the digestive system.
This test provides crucial information about stomach function and helps healthcare professionals diagnose conditions affecting gastric motility. Gastric emptying studies are frequently employed to diagnose gastroparesis, a condition characterized by delayed stomach emptying. This disorder can cause various symptoms, including nausea, vomiting, bloating, and abdominal discomfort.
By measuring the rate of food leaving the stomach, medical professionals can determine the presence of gastroparesis and develop appropriate treatment strategies. Additionally, these studies are useful in evaluating patients with suspected dumping syndrome, a condition where food moves too rapidly from the stomach to the small intestine, resulting in symptoms such as diarrhea, lightheadedness, and sweating. Gastric emptying studies play a vital role in the diagnosis and management of gastrointestinal motility disorders.

Why is a Gastric Emptying Study performed?
A gastric emptying study is performed to evaluate the function of the stomach and diagnose conditions that affect gastric motility. One of the primary reasons for performing this test is to diagnose gastroparesis, a condition in which the stomach takes too long to empty its contents. Patients with gastroparesis often experience symptoms such as nausea, vomiting, bloating, and abdominal pain, which can significantly impact their quality of life.
By measuring the rate at which food leaves the stomach, healthcare providers can confirm the diagnosis of gastroparesis and develop an appropriate treatment plan to help manage the symptoms and improve the patient’s overall well-being. In addition to diagnosing gastroparesis, gastric emptying studies can also be used to evaluate patients with suspected dumping syndrome. This condition occurs when food moves too quickly from the stomach to the small intestine, leading to symptoms such as diarrhea, lightheadedness, and sweating.
By monitoring the movement of food through the digestive system, healthcare providers can determine if dumping syndrome is present and develop a tailored treatment plan to help alleviate the patient’s symptoms. Overall, gastric emptying studies are essential for diagnosing and managing gastrointestinal motility disorders and play a crucial role in improving patient outcomes.
How is a Gastric Emptying Study performed?
A gastric emptying study is typically performed in a nuclear medicine department or imaging center. The test begins with the patient ingesting a meal that contains a small amount of radioactive material, such as scrambled eggs or oatmeal, mixed with a radioactive tracer. The radioactive material is safe and does not cause any harmful effects to the body.
After ingesting the meal, the patient will be positioned under a special camera that can detect the radioactive material as it moves through the digestive system. The camera takes images at specific time intervals to monitor the movement of the food from the stomach into the small intestine. During the test, the patient will be asked to remain as still as possible to ensure clear and accurate images are obtained.
The entire process typically takes several hours, as it is necessary to monitor the movement of food through the digestive system over an extended period of time. Once the test is complete, the images will be reviewed by a radiologist or nuclear medicine physician who will interpret the results and provide a report to the patient’s healthcare provider. The results of the gastric emptying study will help determine how well the stomach is functioning and whether there are any abnormalities in gastric motility that may be contributing to the patient’s symptoms.
A gastric emptying study is a non-invasive procedure that provides valuable information about how well the stomach is functioning and can help diagnose conditions that affect gastric motility. By monitoring the movement of food through the digestive system using a special camera and radioactive tracer, healthcare providers can gain insight into how quickly or slowly food empties from the stomach into the small intestine. This information is crucial for diagnosing conditions such as gastroparesis and dumping syndrome and developing appropriate treatment plans to help manage symptoms and improve patient outcomes.
Interpreting the results of a Gastric Emptying Study
| Metrics | Normal Range | Interpretation |
|---|---|---|
| Gastric Emptying Time | Less than 90 minutes | Normal gastric emptying |
| Gastric Retention at 1 hour | Less than 60% | Normal gastric emptying |
| Gastric Retention at 2 hours | Less than 10% | Normal gastric emptying |
| Gastric Retention at 4 hours | Less than 5% | Normal gastric emptying |
The results of a gastric emptying study provide valuable information about how well the stomach is functioning and can help diagnose conditions that affect gastric motility. After the test is complete, the images will be reviewed by a radiologist or nuclear medicine physician who will interpret the results and provide a report to the patient’s healthcare provider. The report will include information about how quickly or slowly food empties from the stomach into the small intestine and whether there are any abnormalities in gastric motility that may be contributing to the patient’s symptoms.
In general, a normal gastric emptying study will show that approximately 50% of the meal has emptied from the stomach within 1-2 hours after ingestion, with complete emptying occurring within 4 hours. If food takes longer than 4 hours to empty from the stomach, it may indicate delayed gastric emptying, which is characteristic of gastroparesis. On the other hand, if food empties too quickly from the stomach into the small intestine, it may indicate dumping syndrome.
The results of the gastric emptying study will help healthcare providers confirm a diagnosis and develop an appropriate treatment plan to help manage symptoms and improve patient outcomes. Overall, interpreting the results of a gastric emptying study requires specialized knowledge and expertise in nuclear medicine and gastrointestinal motility disorders. Healthcare providers rely on these results to make accurate diagnoses and develop tailored treatment plans for patients with conditions such as gastroparesis and dumping syndrome.
By understanding how well the stomach is functioning and identifying any abnormalities in gastric motility, healthcare providers can provide effective care that addresses the underlying causes of patients’ symptoms.
