What Is Rumination Disorder?
Ruminant syndrome refers to returning food that has not been ingested to the mouth, swallowing or vomiting after chewing. It is effortless, without abdominal discomfort, heartburn or nausea. Patients generally do not cause resentment or even a satisfactory experience. It is predominantly male, most commonly occurs in infants and children with mental disorders, and in adults, and may have fatal complications (aspiration pneumonia). People with normal intelligence can also appear, usually young patients. Family history is common. This disease is often misdiagnosed as gastroesophageal reflux disease.

Causes of Ruminant Syndrome
- The pathogenesis of ruminant disease is not clear. It can be initiated by belching or swallowing. At this time, the reduced pressure of the lower esophageal sphincter (LES) creates a common cavity between the gastroesophagus. Sometimes caused by finger or tongue irritation of the palate and pharynx. Normal development of ruminant children may be to get the attention and attention of parents or positive feedback caused by the taste of reflux food. It is also believed that the occurrence of rumination is related to the peaks of simultaneous contraction of the esophagus and stomach, which may be caused by a sudden increase in intra-abdominal pressure. Some scholars believe that rumination is a skilled thoron reflex process for adults with normal intelligence, because the relaxation time of LES is prolonged during thoron.
Clinical manifestations of ruminant syndrome
- This is manifested by repeated reflux of part of the undigested food to the mouth. Symptoms usually appear within 10 minutes after eating and can last up to 1 to 2 hours after a meal. Its characteristic is that when the food becomes sour, it stops. Weight loss is common and may be related to spitting out reflux food. Some patients present with bulimia nervosa and spit out reflux food to control weight. Rumination is not harmful to health, but some children may experience weight loss or be detrimental to physical development.
Rumination Syndrome Test
- Laboratory inspection
- During gastroduodenal pressure measurement, pressure peaks (called R waves) are visible, forming the illusion of a sudden increase in abdominal pressure.
- 2. Radiography
- Upper gastrointestinal angiography is normal and can be used to exclude other diseases. A gastric emptying scan can be used to exclude gastroparesis.
Rumination Syndrome
- The diagnostic criteria are at least 12 weeks in the past year: Continuously or recurrently returning freshly ingested food to the mouth, then chewing and swallowing; No nausea and vomiting; The process stops when the returned material becomes acidic; Asymptomatic Gastroesophageal reflux, achalasia, or other motility disorders.
Differential diagnosis of ruminant syndrome
- Diseases to be identified include GERD, achalasia, gastroparesis, vomiting, obstruction, and pseudo-obstruction.
Rumination Syndrome Treatment
- For adults with normal intelligence, the treatment is mainly education and explanation, and biofeedback therapy can be used. For people with intellectual disabilities, behavioral restriction therapies can be used. No medication or surgery is needed.
