Why Acid Reflux Gets Worse With Age

Acid reflux is a common concern for many older New Zealanders, and it often becomes more noticeable or troublesome as the years go by. If you have found that the discomfort in your chest or throat seems to be showing up more often or feels stronger than it once did, you are not alone. There are several reasons why acid reflux tends to intensify with age, and understanding them can help you manage the condition with more confidence.
One key reason is that the muscles in our digestive system naturally weaken over time. The lower oesophageal sphincter, the muscle that keeps stomach acid from moving back up into the oesophagus, can lose some of its strength as we age. When this muscle is not closing properly, acid is more likely to escape upward, leading to that familiar burning sensation known as heartburn.
Another factor is that the stomach empties more slowly in older adults. This means food and acid stay in the stomach longer, increasing the chance of reflux occurring after meals. Changes in saliva production can also play a role, since saliva helps neutralise acid and clear it from the oesophagus. As we age, saliva flow often decreases, giving acid more time to irritate the lining of the digestive tract.
Certain health conditions that become more common later in life, such as hiatal hernias, can also contribute to acid reflux. A hiatal hernia occurs when part of the stomach pushes through the diaphragm, which can make it easier for acid to travel upward. Additionally, some medications commonly prescribed for age-related conditions, including certain blood pressure treatments and pain relievers, may relax the sphincter muscle or irritate the stomach lining.
Lifestyle factors matter too. Reduced physical activity, changes in diet, and carrying extra weight around the midsection can all place additional pressure on the stomach, making reflux more likely.
While occasional acid reflux is common and often manageable, frequent or severe symptoms should not be ignored. Persistent reflux can affect quality of life and, over time, may lead to further digestive issues if left unaddressed. Speaking with a healthcare provider is a sensible step if symptoms are becoming more regular or intense.
Understanding why acid reflux changes with age is the first step toward managing it well. With the right awareness and support, many older adults find they can still enjoy meals and daily life with far less discomfort.
