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).


Symptoms vary from person to person, but regurgitation typically:

  • Is effortless, as opposed to forced vomiting
  • Isn't associated with heartburn, abdominal pain or nausea
  • Begins within 30 minutes of eating a meal
  • Stops within 60 minutes
  • Doesn't occur while lying down or sleeping
  • Doesn't respond to standard treatment for GERD
