Acidity, commonly referred to as acid reflux or heartburn, is a condition characterized by the regurgitation of stomach acid into the esophagus, causing a burning sensation in the chest and throat. While occasional acidity is normal, chronic or severe cases may require treatment to alleviate symptoms and prevent complications. The primary goal in acidity treatment is to reduce the production of stomach acid and promote healing of the esophagus. Lifestyle modifications play a crucial role in managing acidity. Patients are advised to avoid trigger foods and beverages such as citrus fruits, spicy foods, caffeine, and alcohol, which can exacerbate symptoms. Eating smaller, more frequent meals and avoiding lying down immediately after eating are also recommended.
