Tests and diagnosisBy Mayo Clinic staff
Your doctor may use some of the following methods to determine if you have dumping syndrome.
- Medical history and evaluation. Your doctor can often diagnose dumping syndrome by taking a careful medical history and then evaluating your signs and symptoms. If you have undergone stomach surgery, that may help lead your doctor to a diagnosis of dumping syndrome.
- Blood sugar test. Because low blood sugar is sometimes associated with dumping syndrome, your doctor may order a test (oral glucose tolerance test) to measure your blood sugar level at the peak time of your symptoms to help confirm the diagnosis.
- Gastric emptying test. A radioactive material is added to food to measure how quickly food moves through your stomach.
