• Repeated regurgitation of food
• Repeated rechewing of food

The health care provider must first rule out physical causes of regurgitation, such as hiatal hernia and pyloric stenosis, which can be misdiagnosed as rumination disorder.

Rumination disorder can cause malnutrition. Laboratory tests (such as serum electrolytes, endocrine - hormonal functions, and a blood test for anemia) can measure the severity of the malnutrition and determine what nutrients need to be increased.
