Regurgitation

Vomiting is an active, coordinated event with nausea beforehand and forceful abdominal contraction. Regurgitation has neither. Material simply arrives back in the mouth, often when position changes.

That difference points at mechanism. Vomiting suggests the stomach or a systemic cause. Regurgitation suggests a barrier that is not holding or an esophagus that is not clearing. Describing which one you actually experience is one of the more useful things you can tell a physician.

A failing valve at the top of the stomach is the most common explanation, frequently alongside a hiatal hernia that has pulled the junction out of position.

Less commonly, the esophagus itself is not emptying. In achalasia the lower valve fails to relax and food collects above it, returning undigested some time after eating. A pouch in the esophageal wall can trap food and release it later. Rumination is a learned, often unconscious pattern of effortless return shortly after meals, and it is treated behaviorally rather than surgically.

• Incompetent valve at the esophagogastric junction
• Hiatal hernia displacing the junction
• Achalasia or other motility failure
• An esophageal pouch trapping food
• Rumination, a behavioral pattern with a behavioral treatment

Material reaching the throat at night can be inhaled. Repeated aspiration causes cough, worsens asthma, and in some cases leads to pneumonia. Nighttime regurgitation is the version to take seriously.

There is also a quality of life cost that people minimize. Sleeping propped up, avoiding evening meals, and carrying a fear of eating out are real limits, and they are not something to simply live with.

Endoscopy inspects the esophagus and stomach and identifies hernias, retained food, and inflammation. A barium swallow shows behavior in motion and reveals pouches and emptying problems well.

Manometry is particularly important here, because motility disorders are a real possibility and because any procedure altering the valve must be tailored to esophageal function. Impedance and pH testing distinguish acid from non acid events, which explains why medication has not helped.

Because the problem is usually mechanical, acid suppression often disappoints. Behavioral changes reduce events, particularly meal timing and elevating the head of the bed. When testing confirms a mechanical cause and symptoms are limiting, procedural options that restore the barrier are discussed, tailored to the motility findings.

Be evaluated sooner if you are waking choking, if you have had pneumonia, if food returns undigested hours later, or if you are losing appetite or avoiding meals.
