Rumination Disorder is a feeding disorder characterised by the frequent regurgitation or bringing back up of ingested food into the mouth, where it may be re-chewed, re-swallowed, or spit out. This behaviour is generally seen within minutes of eating and is not due to a stomach sickness or digestive problem. It is most common in infants, children and people with developmental difficulties, but it can occur in teenagers and adults.

The specific cause of Rumination Disorder is not always known. It can occur as a result of stress, worry, emotional challenges, learnt behaviours or developmental conditions. Symptoms are usually regurgitation of food after meals, weight loss, poor growth in youngsters, bad breath, damaged teeth, stomach discomfort and nutritional deficiencies if not treated.

Diagnosis is based on a thorough medical history, physical examination, and exclusion of other gastrointestinal problems such as acid reflux or illnesses associated with vomiting. Treatment is behavioural, including diaphragmatic breathing techniques and habit reversal training, as well as addressing the emotional or psychological reasons behind the tic. Nutritional supplementation could also be prescribed to restore healthy growth and prevent deficits.

Most people with Rumination Disorder can greatly lessen their symptoms, improve their nutrition, and have a better quality of life with early diagnosis, proper treatment, and support from family members.
