In plain language

Heartburn and acid reflux are common digestive disorders that affect many people, particularly as they age. They occur when stomach acid flows back up into the esophagus, causing a burning sensation in the chest. While these conditions can be uncomfortable and disruptive, they can often be managed effectively with lifestyle changes and medication.

Heartburn and acid reflux are digestive conditions that can cause discomfort in the chest and throat. Heartburn occurs when stomach acid backs up into the esophagus, leading to a burning sensation in the chest. Acid reflux refers to the actual backflow of stomach acid.

These conditions are common, especially among older adults. Age-related changes in digestion, such as a weakened lower esophageal sphincter, can increase susceptibility to acid reflux. Certain foods, medications, and lifestyle factors can also contribute.

Chronic acid reflux can lead to gastroesophageal reflux disease (GERD), a more serious condition that may require medical treatment. Understanding and managing triggers can help reduce symptoms and improve comfort.

Key Information

Review the most relevant symptoms, risk factors, and common care approaches in one place.

Risk Factors

Common risk factors for heartburn and acid reflux include:

  • Diet: Spicy, fatty, or acidic foods can trigger symptoms.

  • Obesity: Excess weight increases abdominal pressure.

  • Smoking: Weakens the lower esophageal sphincter.

  • Alcohol and caffeine: Can irritate the esophagus and relax the sphincter.

  • Medications: Certain drugs, such as NSAIDs and calcium channel blockers, may cause reflux.

Symptoms

Typical symptoms of heartburn and acid reflux include:

  • Burning sensation: Burning in the chest or throat, often after eating.

  • Regurgitation: Sour or bitter-tasting acid backing up into the throat or mouth.

  • Difficulty swallowing: Feeling like food is stuck in the throat.

  • Chest pain: May mimic heart-related pain.

  • Chronic cough or sore throat: Especially at night.

Coping Strategies

Strategies to manage symptoms of heartburn and acid reflux include:

  • Dietary changes: Avoid trigger foods and eat smaller meals.

  • Lifestyle adjustments: Elevate the head of the bed and avoid lying down after meals.

  • Weight management: Maintain a healthy weight.

  • Quitting smoking: Smoking cessation can help reduce symptoms.

  • Stress reduction: Practice relaxation techniques to reduce stress.

Common Treatments

Common treatments for heartburn and acid reflux include:

  • Antacids: Over-the-counter medications that neutralize stomach acid.

  • H2 blockers: Reduce acid production in the stomach.

  • Proton pump inhibitors (PPIs): Stronger acid reducers that help heal the esophagus.

  • Lifestyle changes: Dietary adjustments and weight loss.
