Mayo Clinic doctors start by obtaining an accurate medical history and asking about symptoms. This initial exam, and sometimes observation of a person's behavior, may be enough to diagnose rumination syndrome.
Mayo doctors may use these tests to rule out other causes of symptoms of rumination syndrome:
- Esophagogastroduodenoscopy. Allows your doctor to inspect your esophagus, stomach and upper part of the small intestine (duodenum). The doctor may remove a small tissue sample (biopsy) for further study.
- Gastroduodenal manometry. Tests the muscles involved in digestion.
- Gastric emptying. Tests how long it takes food containing a radioactive marker to empty from your stomach. Another version of this test also can measure how long it takes food to travel through the small intestine and colon.
- Ultrasound or contrast X-rays. May be used in infants to rule out hiatal hernia and narrowing of the opening from the stomach to the small intestine (pyloric stenosis).
