Lower esophageal closure and backflow & Heartburn and warning symptoms

Lower esophageal closure and backflow

Reflux occurs when the muscle at the lower esophagus fails to close properly or relaxes at the wrong time. Stomach contents move backward and irritate the esophagus. Occasional reflux is common, but frequent symptoms or lining damage can indicate chronic reflux disease. Excess weight, pregnancy, tobacco exposure, and hiatal hernia increase likelihood. Some foods, drinks, and medicines can worsen symptoms in susceptible people. Heartburn is burning in the chest or throat, but reflux can occur without it.

Heartburn and warning symptoms

Heartburn is burning in the chest or throat, but reflux can occur without it. Sour taste, regurgitation, cough, hoarseness, swallowing difficulty, and asthma-like symptoms are possible. Untreated disease can cause inflammation, scarring, or Barrett esophagus. Chest pain with breathlessness or jaw or arm pain needs immediate medical attention because it may reflect a heart problem rather than uncomplicated reflux. Symptom overlap must not delay evaluation.
