Rumination syndrome comes under the category of conditions of functional gastrointestinal disorders. It is a condition where people either vomit or re-swallow their drink or food and regurgitate after eating. Such a condition worsen with time and can occur irrespective of age. Like a functional disorder with no physical abnormality or disease, the patient suffers from real issues. Such a condition results from the dysregulation between the brain and the GI system’s communication. Other factors causing rumination include nerve sensitivity in the GI tract or psychological stressors that can worsen the symptoms. The patients with a medical history of rumination syndrome state that the symptoms begin with triggering events. These events can be viral infections, stress, or GI disease. As these infections, stress, or even surpass, the vomiting behaviour remains and becomes a habit. As a result, when liquid or good enters the stomach, the body learns a new behaviour, i.e., contraction of abdominal muscles. This leads to pressure on the stomach, and the food or liquid returns to the throat. The symptoms discussed are common in rumination patients. However, every patient might experience a different presentation. It means the syndrome can act differently in every person. While some may vomit immediately after eating a bite, others might eat a good amount of food before the vomiting behaviour begins. Also, some feel pain while eating, and some feel nausea. Therefore, every person’s body behaves differently to rumination syndrome.
