Rumination Syndrome

Rumination syndrome is a rare and poorly understood medical condition characterized by the repeated regurgitation of food from the stomach into the mouth, often accompanied by re-chewing and re-swallowing of the regurgitated food.

Causes and Risk Factors

The exact cause of rumination syndrome is not well understood, but it is thought to be related to a combination of factors, including:

• Abnormalities in the functioning of the upper digestive tract, such as delayed gastric emptying or gastroesophageal reflux disease (GERD)
• Disorders of the autonomic nervous system, which regulates involuntary functions such as digestion
• Psychological factors, such as stress, anxiety, and eating disorders
• Genetic predisposition

Symptoms

The primary symptom of rumination syndrome is the repeated regurgitation of food from the stomach into the mouth, often within a short period of time (usually 1-2 hours) after eating. Other symptoms may include:

• Re-chewing and re-swallowing of regurgitated food
• Nausea and vomiting
• Abdominal pain or discomfort
• Bloating and gas
• Weight loss or malnutrition due to inadequate nutrition

Diagnosis

Rumination syndrome can be difficult to diagnose, as the symptoms are often similar to those of other conditions, such as gastroesophageal reflux disease (GERD) or bulimia nervosa. Diagnosis is typically made based on a combination of:

• Medical history and physical examination
• Upper endoscopy or other imaging tests to rule out other conditions
• Manometry or other tests to assess the functioning of the upper digestive tract
• Psychological evaluation to assess for underlying psychological factors

Treatment

Treatment for rumination syndrome typically involves a combination of medical, dietary, and behavioral therapies. Medical treatments may include:

• Medications to reduce symptoms of nausea and vomiting
• Prokinetic agents to improve gastric emptying
• Antacids or acid reducers to manage symptoms of GERD

Dietary changes may include:

• Eating smaller, more frequent meals
• Avoiding trigger foods that can exacerbate symptoms
• Increasing fiber intake to promote regular bowel movements

Behavioral therapies may include:

• Cognitive-behavioral therapy (CBT) to address underlying psychological factors
• Relaxation techniques, such as deep breathing or meditation, to reduce stress and anxiety

Complications

If left untreated, rumination syndrome can lead to a range of complications, including:

• Malnutrition and weight loss due to inadequate nutrition
• Dental erosion and tooth decay due to frequent regurgitation of acidic stomach contents
• Esophageal damage or stricture due to chronic vomiting
• Psychological complications, such as depression and anxiety, due to the chronic nature of the condition
