Rumination Disorder: The Unheard Eating Disorder You Need To Know About

Last Update on September 19, 2023 : Published on February 17, 2021
Rumination Disorder

Commonly affecting infants, toddlers, and adults, rumination syndrome or disorder is a rare yet chronic eating disorder that makes people regurgitate food. Regurgitation isn’t like vomiting – it is not forced from the mouth – regurgitated food may be re-chewed or spit out.

Rumination disorder involves bringing up the previously ingested food back up to spit out or re-chewed.

In infants, rumination disorder doesn’t necessarily need medical interference but the condition can continue into later years. Children and adults with learning or developmental disabilities are more commonly diagnosed with this disorder.

In other eating disorders such as bulimia nervosa and anorexia nervosa, self-induced vomiting is a common symptom but in rumination disorder, the vomiting or the regurgitation is automatic and, in some cases, a reflex.

Rumination Disorder: Symptoms

Rumination Disorder

Some of the signs and symptoms of rumination disorder can be:

  • Regurgitating or re-chewing food
  • Indigestion and stomach problems
  • Bad breath
  • Tooth decay
  • Weight loss
  • Dry mouth or chapped lips

The signs and symptoms of this disorder are pretty much similar in both toddlers and adults, however, adults are more likely to spit out the food while toddlers are more likely to re-chew the food.

Causes Of Rumination

The evidence of why this disorder occurs is unknown but it is speculated that some people might develop this syndrome if they are going through some developmental delays or emotional distress.

Another cause can be; an increase in abdominal pressure. This disorder can be confused with bulimia nervosa, GERD (Gastroesophageal Reflux Disease), or any other gastro-related diseases.

People with chronic or reoccurring anxiety disorders, depressive disorders, or psychiatric disorders are also prone to this disorder.

Rumination Disorder: Diagnosis

diagnosis of rumination disorder

Rumination disorder can be diagnosed by a doctor via a physical examination. To be diagnosed with rumination syndrome, the patient must show the symptoms – specifically regurgitating – for at least 3 months.

According to the DSM-5, the patient must meet the following to be diagnosed with rumination disorder:

  • Regurgitating food for at least a month. This includes re-chewing, re-swallowing, or spitting up food.
  • Regurgitation isn’t because of a gastrointestinal condition or any other medical health issue.
  • The disorder does not occur with other eating disorders such as anorexia nervosa, bulimia nervosa, binge-eating disorder (BED), or restrictive food intake disorder.
  • If the disorder is occurring with another mental health disorder, the symptoms are severe enough to seek treatment. For example; intellectual or learning disabilities.

A doctor may also ask for additional tests such as:

  • Gastric emptying test: To help the doctor determine how long it takes for the stomach to empty food.
  • Upper endoscopy: To help the doctor examine the esophagus and stomach to see for potential blockages or obstructions.
  • Stomach or esophagus x-rays.

Treatment for rumination may differ for people depending on their age groups and developmental abilities.

One of the major treatments for this disorder is a behavioral therapy that is usually combined with diaphragmatic breathing. Diaphragmatic breathing helps prevent regurgitation and abdominal constrictions. Biofeedback is also a part of behavioral therapy for this disorder.

Certain prescribed medications can also help with regurgitation and abdominal cramps. Although, it is recommended that you speak with your doctor before taking any medications.
