Heartburn is a common issue that affects many people, often caused by eating too quickly or consuming spicy foods. However, as we age, our risk of developing heartburn increases due to the natural decline in muscle tone.
According to Yi Qin, a gastrointestinal specialist at Cleveland Clinic, the esophageal sphincter – a muscle that prevents acid from entering the esophagus – weakens with age. This makes it easier for stomach contents to back up into the esophagus and even reach the mouth. Additionally, as we grow older or gain weight, our risk of developing a hiatal hernia – a condition where the upper part of the stomach protrudes through the diaphragm – increases.
Both heartburn and hiatal hernias are linked to acid reflux, making them more likely to occur in people who age or experience weight gain.
