Heartburn occurs when stomach acid flows back into the esophagus, the tube that connects the throat to the stomach. This backflow, known as acid reflux, can cause a burning sensation in the chest or throat, often triggered by certain foods, overeating, or lying down after eating. Factors like obesity, pregnancy, and certain medications can also contribute to the frequency and severity of heartburn episodes. Managing diet and lifestyle choices can help alleviate symptoms.
