Why heartburn becomes more prevalent with age
As the body gets older, several internal changes can increase the likelihood of experiencing heartburn, also known as acid reflux. It is a common misconception that this burning sensation is a normal part of getting older, but it is actually a symptom of underlying issues that need attention.
Weakened lower esophageal sphincter
One of the main reasons for increased heartburn is the weakening of the lower esophageal sphincter (LES), the ring of muscle that acts as a valve between the esophagus and the stomach. Over time, this muscle can lose its tone and ability to close properly, allowing stomach acid to flow back up into the esophagus. This muscle weakness is a natural part of the aging process, but lifestyle and dietary factors can accelerate it.
Slowed digestive system
With age, the entire digestive system tends to slow down, including the process of gastric emptying, which is the time it takes for food to leave the stomach. When food and digestive acids remain in the stomach longer, the pressure builds, increasing the likelihood of reflux. This delayed emptying can make post-meal heartburn more frequent and severe.
Increased likelihood of hiatal hernia
A hiatal hernia occurs when the upper part of the stomach pushes up through the diaphragm into the chest cavity. The risk of developing this condition increases with age as the supporting tissues weaken. A hiatal hernia can compromise the function of the LES, making it easier for acid to reflux into the esophagus and causing heartburn.
Polypharmacy and medication side effects
Many older adults take multiple medications (a practice known as polypharmacy) for various chronic health conditions, such as hypertension, diabetes, and osteoporosis. A wide range of drugs can either relax the LES or irritate the lining of the esophagus, contributing to heartburn. Common culprits include:
- Pain relievers (NSAIDs) like ibuprofen and aspirin
- Certain blood pressure medications (calcium channel blockers)
- Some antidepressants
- Certain osteoporosis drugs
Comparison: Heartburn in Younger vs. Older Adults
| Feature | Younger Adults | Older Adults |
|---|---|---|
| Symptom Reporting | Typically report classic symptoms like a burning chest sensation. | May report less frequent or severe typical symptoms due to decreased esophageal sensation. |
| Symptom Presentation | Often present with a clear, burning sensation after eating or lying down. | More likely to present with atypical symptoms, such as chronic cough, sore throat, or dysphagia (difficulty swallowing). |
| Severity of Damage | Generally less severe mucosal damage on endoscopy due to shorter duration of acid exposure. | More likely to have severe mucosal damage and complicated reflux disease, even with milder symptoms. |
| Risk of Complications | Lower risk of developing severe complications like Barrett's esophagus or esophageal cancer. | Higher risk of serious complications, including esophagitis, strictures, Barrett's esophagus, and esophageal cancer. |
| Medical Management | Often responds well to lifestyle changes and over-the-counter medication. | Requires careful medical management due to polypharmacy and other comorbidities. |
How to manage and prevent heartburn in older adults
For older adults experiencing persistent heartburn, it is essential to take a proactive approach to management and prevention. Because of the higher risk of complications, relying solely on lifestyle changes is often not enough, and medical evaluation is recommended.
Lifestyle modifications
- Dietary adjustments: Identify and avoid trigger foods such as spicy meals, fatty or fried items, citrus fruits, tomatoes, caffeine, and alcohol. Focus on a diet rich in whole grains, vegetables, and lean protein. Keep a food diary to track what causes discomfort.
- Eating habits: Eat smaller, more frequent meals rather than large, heavy ones. Avoid eating within two to three hours of bedtime to give your stomach time to empty before you lie down.
- Elevating the head of the bed: Raise the head of your bed by six to eight inches using blocks or a wedge pillow to help gravity keep stomach acid down while you sleep.
- Weight management: Maintaining a healthy weight reduces pressure on the abdomen and the LES, which can alleviate reflux symptoms.
- Quit smoking: Smoking can relax the LES, making it easier for acid to travel up the esophagus. Quitting is a major step toward reducing heartburn.
Medical and professional care
- Over-the-counter medications: For occasional heartburn, antacids can provide quick relief by neutralizing stomach acid. H2 blockers reduce acid production and offer longer relief. Proton pump inhibitors (PPIs) are a more potent class of medication that can block acid production and heal damaged esophageal tissue. However, long-term use of certain medications should always be discussed with a doctor due to potential side effects and interactions with other drugs.
- Prescription medications: For more severe or chronic cases (GERD), a doctor may prescribe stronger doses of H2 blockers or PPIs. These require medical supervision due to potential drug interactions and side effects common in older patients.
- Regular check-ups: Given the potential for serious complications like Barrett's esophagus, especially in older adults, regular medical check-ups and early endoscopy may be recommended. This helps to monitor the health of the esophageal lining and catch any issues early.

Conclusion
Heartburn is not an inevitable consequence of aging but rather a signal of underlying digestive changes that become more prevalent with time. Factors such as a weakened LES, slower digestion, and common medications contribute to its increased frequency in older adults. Unlike in younger individuals, heartburn symptoms can be milder or present atypically in seniors, even when the underlying damage to the esophagus is more severe. For this reason, it is vital to consult a healthcare provider for proper diagnosis and management, especially if symptoms are persistent. By combining informed lifestyle modifications with appropriate medical care, older adults can effectively manage their heartburn and prevent more serious long-term complications, significantly improving their quality of life.
