Heartburn 101: What Causes It and How to Prevent It

Heartburn is a common condition that many people experience, often as a burning sensation in the chest or throat. While occasional heartburn is usually harmless, frequent episodes can interfere with daily life and may indicate an underlying issue, such as gastroesophageal reflux disease (GERD). At San Diego Gastroenterology in San Diego, CA, our team specializes in diagnosing and treating heartburn to help patients find relief and improve their quality of life.

What Causes Heartburn?

Heartburn occurs when stomach acid flows back into the esophagus, the tube that connects your mouth to your stomach. This backflow, known as acid reflux, irritates the lining of the esophagus and causes the characteristic burning sensation. Several factors can contribute to heartburn, including dietary choices, lifestyle habits, and certain medical conditions. Common triggers include spicy or fatty foods, caffeine, alcohol, and large meals, which can relax the lower esophageal sphincter (LES)—the muscle that acts as a barrier between the stomach and esophagus. When the LES doesn’t close properly, stomach acid can escape into the esophagus. Other factors, such as obesity, smoking, pregnancy, or lying down shortly after eating, can also increase the risk of heartburn.

How to Prevent Heartburn

Preventing heartburn often involves making simple lifestyle changes to reduce triggers and improve digestion. Eating smaller, more frequent meals instead of large portions can help prevent the stomach from becoming overly full, reducing pressure on the LES. Avoiding trigger foods, such as citrus, chocolate, and fried items, can also minimize the likelihood of acid reflux. Maintaining a healthy weight is another important step, as excess weight can put pressure on the abdomen and LES. Quitting smoking and limiting alcohol consumption can further reduce the risk of heartburn. Additionally, waiting at least two to three hours after eating before lying down or going to bed can help prevent acid from flowing back into the esophagus. For individuals who experience frequent or severe heartburn, over-the-counter antacids or medications may provide temporary relief. However, persistent symptoms should be evaluated by a gastroenterologist to rule out underlying conditions and develop a long-term management plan.

How San Diego Gastroenterology Can Help

At San Diego Gastroenterology, our team begins with a thorough evaluation to identify the underlying causes of your symptoms, which may include dietary habits, lifestyle factors, or medical conditions like GERD. Diagnostic tests, such as endoscopy or pH monitoring, may be recommended to assess the severity of acid reflux and its impact on the esophagus. Based on your evaluation, we create a personalized treatment plan that may include dietary modifications, medications to reduce acid production, or advanced therapies for more severe cases.
