What Causes Heart Burn | Bio Anatomy Art | Gut Health

Heartburn is a common condition that many people experience, but it has nothing to do with the heart. Instead, it begins in the digestive system, specifically where the esophagus meets the stomach. When we eat, food travels down the esophagus and enters the stomach through a muscular valve called the lower esophageal sphincter, or LES. Under normal conditions, this valve opens to let food in and then closes tightly, keeping stomach acid contained. However, if the lower esophageal sphincter becomes weak, or relaxes at the wrong time, stomach acid can escape upward into the esophagus. This backward flow of acid is called acid reflux. The lining of the esophagus is not built to handle strong stomach acid. When acid comes in contact with it, the tissue becomes irritated and inflamed. This irritation creates the burning pain in the chest or throat that we call heartburn. Certain foods like spicy meals, citrus fruits, caffeine, alcohol, or lying down after eating can increase reflux likelihood and worsen heartburn. While occasional heartburn is common, frequent episodes may indicate gastroesophageal reflux disease or GERD. Understanding heartburn helps make better choices to protect digestive health.
