Acid reflux (GERD).

Overview

Gastroesophageal reflux disease (GERD) develops when stomach contents repeatedly flow back into the esophagus, causing troublesome symptoms or complications.

A condition may appear differently between people, so a symptom list alone cannot establish a diagnosis. Age, medical history and other circumstances affect assessment.

Signs and symptoms

Typical symptoms include burning discomfort behind the breastbone and a sour or acidic taste from regurgitation. Some people have cough, hoarseness or throat symptoms. Difficulty swallowing, persistent vomiting, bleeding or unintended weight loss should not be dismissed as ordinary heartburn.

Causes and risk factors

Factors may include the function of the lower esophageal sphincter, certain foods, obesity, pregnancy and other conditions.

Risk factors do not guarantee that a person will develop this condition, and a diagnosis can occur even without obvious risk factors.

Diagnosis and tests

Persistent symptoms may require clinical evaluation; alarm features can prompt endoscopy or other testing.

Tests are chosen for the individual situation. No picture or AI-generated response can confirm this condition.

Care and treatment

Management may include meal timing changes, trigger evaluation and medicines such as acid suppressants when indicated.

Treatment plans must consider severity, other illnesses, medication safety and personal preferences. Do not start or change prescribed treatment using this article alone.

Prevention and daily living

Lifestyle measures may include allowing time between dinner and lying down, considering personally relevant food triggers and reviewing weight if appropriate. Persistent reflux or alarm signs need a clinician rather than indefinite self-medication.

Individual care plans may differ, particularly in pregnancy, childhood, older age or when other illnesses are present. The linked clinical source provides more context.

When to seek help

Trouble swallowing, vomiting blood, black stools or significant unintended weight loss requires prompt assessment.

If symptoms are severe, rapidly worsening or you feel unsafe, seek local emergency services. Do not wait for an online reply.
