A diagnosis is made via a medical professional’s evaluation.
Medical professionals usually diagnose rumination disorder when:
- Individuals repeatedly regurgitate food over a period of ≥ one (1) month.
- GI disorders that can cause regurgitation (such as gastroesophageal reflux [GERD] and Zenker diverticulum) and other eating disorders (such as anorexia nervosa) have been ruled out.
Medical professionals may observe the individual regurgitating food, or the individual may report it.
If rumination disorder is suspected or diagnosed, medical professionals evaluate nutritional status to check for weight loss and nutritional deficiencies.
