Rumination Disorder (Rumination)

The term “rumination” comes from the Latin word for “ruminating.” It refers to a behavior in which a child effortlessly brings food that has already been eaten and swallowed back up into the mouth. There, it is chewed again and then either swallowed or spit out. This usually happens calmly, often daily, and without any signs of nausea or disgust.

Rumination disorder is classified as an eating disorder or feeding disorder. In the ICD (under F98.21) and DSM-5 diagnostic systems, it is listed as a distinct condition alongside related forms such as feeding disorder of infancy and childhood or pica (the eating of inedible substances). It most commonly occurs in infants between the ages of about three and twelve months, but can also affect older children, adolescents, and adults. For it to be classified as a disorder, the regurgitation must occur repeatedly over at least one month and cannot be explained by a physical cause.

Many babies spit up. In the first few months of life, up to 70 percent of healthy infants occasionally regurgitate stomach contents because the muscle at the entrance to the stomach is not yet fully developed. This harmless spitting up and gastroesophageal reflux usually resolve on their own by the time most children are about 18 months old. In cases of pathological reflux disease, additional symptoms may occur: arching the back during feeding, restlessness, refusal to eat, or poor weight gain.

The picture is different with rumination. In this case, there is no underlying disease of the esophagus or stomach. It is important to distinguish this from vomiting: Vomiting occurs involuntarily, is accompanied by retching, and is usually associated with nausea. In contrast, the regurgitation associated with rumination occurs effortlessly and sometimes seems almost casual or intentional. Before a diagnosis is made, doctors must rule out physical causes such as reflux, a narrowing of the esophagus, or other gastrointestinal disorders.

A typical pattern is one that recurs, often beginning shortly after meals. Parents frequently observe:

• Food is brought back into the mouth without gagging and without any visible effort.
• The child chews it again and either swallows it or spits it out.
• Some infants make tensing or sucking movements with their torso and mouth as if they were triggering the retching themselves.
• There are no signs of illness such as fever, abdominal pain, or nausea.

Older children and adolescents often try to hide this behavior and avoid eating in company. If rumination persists for a longer period, it can lead to weight loss, nutritional deficiencies, bad breath, or sores on the teeth and esophagus. Such consequences are a clear sign to seek medical advice.

There is no single cause. Experts believe it stems from a learned, body-based pattern that has taken on a life of its own. In infants, gagging often becomes a form of self-soothing when they lack attention, stimulation, or a reliable routine elsewhere. The professional literature therefore also cites tensions in the early relationship between the child and the primary caregiver, as well as stressful life circumstances, as contributing factors. Rumination occurs somewhat more frequently in children with an intellectual disability or a brain impairment.

It is important for parents to understand that this behavior is not directed against them and is not the result of parenting mistakes. It is a coping mechanism of the body that can be changed with patience and the right support. Feelings of guilt do not help the child. A calm, attentive attitude, however, does.

The good news: In most cases, rumination can be treated effectively. Behavioral therapy approaches are central to treatment. For infants, warm, reliable care is especially important: more physical contact, calm mealtimes, a clear daily routine, and attentive care—especially in the minutes after eating. Often, the behavior disappears when the child receives enough closeness and stimulation in other ways.

For older children and adolescents, techniques are added to interrupt the automatic gagging reflex. These include learning relaxed abdominal breathing, which changes the movement of the diaphragm, as well as consciously recognizing the situations in which rumination occurs. As parents, you can provide support by keeping mealtimes relaxed, avoiding pressure and reprimands, and not reacting to the behavior with excessive agitation. In cases of weight loss or signs of malnutrition, the treating physician will also assess the child’s nutritional status.

Seek medical help if your child regularly spits up food over several weeks, if they are losing weight or failing to thrive, or if you’re unsure whether there might be an underlying medical condition causing the spitting up. Your first point of contact is your child’s pediatrician’s office. They will first rule out physical causes such as reflux and, if necessary, refer you to a child and adolescent psychiatry (KJP) practice or to specialized feeding and eating counseling services.

Rückenwind Eltern is there to support you as a coach: helping you sort through the situation, prepare for discussions, and manage your own stress. A diagnosis and medical treatment should be handled exclusively by a medical or psychotherapeutic specialist or a child and adolescent psychiatry clinic. If you observe this behavior, seek this professional evaluation early on. When addressed early, the pattern is easier to change.
