Heartburn is a common condition characterized by a burning sensation in the chest or throat, often accompanied by a sour or bitter taste in the mouth. It typically occurs when stomach acid refluxes back into the esophagus, causing irritation and inflammation of the esophageal lining.

The sensation of what does heartburn feel like to person, but it is often described as a discomfort or pain that starts behind the breastbone and may radiate upwards towards the throat or jaw. Some individuals may also experience symptoms such as regurgitation of stomach contents, difficulty swallowing, or a sensation of food sticking in the throat.

Heartburn symptoms tend to worsen after eating, especially after consuming spicy or fatty foods, citrus fruits, caffeine, or alcohol. Additionally, lying down or bending over may exacerbate symptoms. While occasional heartburn is common and usually harmless, frequent or severe heartburn may indicate gastroesophageal reflux disease (GERD) or other underlying conditions.

It's essential to pay attention to your symptoms and seek medical advice if you experience persistent or severe heartburn, as it may require treatment to prevent complications and improve quality of life.
