Acid reflux, or gastroesophageal reflux disease (GERD), involves the backflow of stomach acid into the esophagus, causing discomfort. While often associated with younger individuals, this condition can develop or worsen at any stage of life, including later years. Understanding age-related changes in the digestive system can clarify why acid reflux may emerge or intensify in older adulthood.
Understanding Later-Life Onset
Acid reflux symptoms can develop or worsen as individuals age. Over 20% of Americans aged 60 and above experience GERD, with this figure rising to more than 30% among those over 70. Acid reflux is the most common upper gastrointestinal disorder encountered in older patients.
Factors Contributing to Acid Reflux in Older Adults
The development or worsening of acid reflux in later life often relates to several age-related physiological changes within the digestive system. A primary factor is the weakening of the lower esophageal sphincter (LES) muscle, which acts as a barrier preventing stomach acid from flowing back into the esophagus. This muscle can lose tone with age, leading to less effective closure.
Slower esophageal clearance, where the esophagus takes longer to clear acid, increases exposure time. Delayed gastric emptying, where food remains in the stomach longer, also contributes by prolonging stomach acid presence. Reduced saliva production, which helps neutralize stomach acid, can further impair protective mechanisms.
The increasing prevalence of hiatal hernias with age also plays a role, as this condition involves a portion of the stomach pushing through the diaphragm, disrupting the LES. Many older adults also take various medications for other health conditions that can relax the LES or directly irritate the esophageal lining. Common culprits include nonsteroidal anti-inflammatory drugs (NSAIDs), calcium channel blockers, certain blood pressure medications, sedatives, and some antibiotics. While lifestyle factors like diet, physical activity, and weight can contribute, physiological and medication-related influences are more pronounced in older age.
Recognizing Symptoms and Seeking Diagnosis
The symptoms of acid reflux in older adults can differ from those experienced by younger individuals. While classic heartburn and regurgitation can occur, older adults may experience less pronounced heartburn or more atypical symptoms. These can include non-cardiac chest pain, difficulty swallowing (dysphagia), a chronic cough, or hoarseness. Other indicators might be unexplained weight loss or anemia. These varied symptoms can make diagnosis challenging, as they may be mistaken for other health conditions.
Seek medical attention for new or worsening symptoms, especially if persistent or including concerning signs such as difficulty swallowing, unexplained weight loss, or gastrointestinal bleeding. A healthcare provider will begin with a symptom assessment and medical history review. In some cases, a trial of lifestyle changes or medication may be suggested. Further diagnostic tests, such as an endoscopy, might be recommended for older adults with new or persistent symptoms to visualize the esophagus and rule out complications.
Managing Acid Reflux Later in Life
Management strategies for acid reflux in older adults involve lifestyle adjustments and, when appropriate, medication. Dietary modifications include avoiding common trigger foods like spicy or fatty items, chocolate, mint, citrus, and carbonated or caffeinated beverages. Eating smaller, more frequent meals can help reduce pressure on the stomach. Avoiding late-night eating, waiting at least three hours before lying down after a meal, can also prevent acid reflux. Elevating the head of the bed by six to nine inches during sleep uses gravity to keep stomach contents down.
Maintaining a healthy weight can reduce abdominal pressure. Quitting smoking can improve symptoms, as smoking can weaken the LES. Over-the-counter medications such as antacids, H2 blockers (like famotidine), and proton pump inhibitors (PPIs, like omeprazole) help manage symptoms by neutralizing or reducing stomach acid. Older adults should consult a doctor before starting any new medication, given potential interactions with other drugs and long-term use implications. A healthcare provider can help determine the most appropriate and safest treatment plan.
