Heartburn

Heartburn is a common digestive symptom characterized by a burning sensation in the chest, often after eating or lying down. It occurs when stomach acid flows backward into the esophagus, irritating its lining.

The esophagus is not designed to tolerate acid, which is why this backflow can cause discomfort. While occasional heartburn is common, frequent or persistent symptoms may signal a more serious condition.

Understanding acid reflux

Acid reflux happens when the lower esophageal sphincter (LES), the muscle that separates the stomach from the esophagus, does not close properly. When this barrier weakens or relaxes inappropriately, stomach acid can travel upward, causing symptoms.

Heartburn vs acid reflux vs GERD

Heartburn is a symptom. Acid reflux describes the process that causes the symptom. gastroesophageal reflux disease (GERD) is a chronic condition in which acid reflux occurs frequently, leading to ongoing symptoms or complications. If heartburn happens more than twice a week, GERD may be present and should be evaluated by a gastroenterologist.

Certain foods, lifestyle factors, or medical conditions can trigger heartburn. Common triggers include fatty or spicy foods, citrus, caffeine, alcohol, and chocolate, as well as large meals. Lying down shortly after eating can also worsen symptoms.

Obesity, pregnancy, smoking, and certain medications may increase pressure on the stomach or weaken the LES, making reflux more likely.

Burning sensation in the chest

The hallmark symptom of heartburn is a burning feeling behind the breastbone. It may worsen after meals, when bending over, or when lying flat.

Regurgitation

Some patients experience a sour or bitter taste in the mouth due to stomach acid rising into the throat. Sometimes food or liquid may reflux into the throat or mouth.

Symptoms that may indicate GERD

When heartburn becomes chronic, additional symptoms may develop, including difficulty swallowing, persistent cough, hoarseness, throat irritation, or chest discomfort that mimics heart pain. Long-term untreated GERD can lead to complications such as esophagitis, strictures, Barrett’s esophagus and even esophageal cancer

Treatment depends on symptom frequency and severity. Many patients find relief through lifestyle adjustments and over-the-counter acid-reducing medications. For more persistent cases, prescription medications such as proton pump inhibitors and potassium competitive acid blockers may be recommended to decrease acid production and allow the esophagus to heal.

Preventive strategies include eating smaller meals, avoiding trigger foods, maintaining a healthy weight, quitting smoking, and avoiding lying down for at least two to three hours after eating. Elevating the head of the bed may also help reduce nighttime symptoms.

If heartburn is frequent, worsening, or interfering with daily life, it’s time to seek expert care. At NYGA, our gastroenterologists use evidence-based treatments and advanced technology to diagnose and manage reflux-related conditions.
