Common triggers for heartburn include consuming large meals, lying down after eating, obesity, pregnancy, smoking, and certain foods and drinks like citrus, chocolate, spicy foods, alcohol, and coffee. Symptoms typically include a burning sensation in the chest, regurgitation of food or sour liquid, and difficulty swallowing. Managing heartburn often involves lifestyle changes such as eating smaller meals, avoiding food triggers, maintaining a healthy weight, and quitting smoking. Over-the-counter medications like antacids, H2 receptor blockers, and proton pump inhibitors can also help alleviate symptoms. If heartburn occurs frequently or is severe, it is important to consult a doctor for further evaluation and treatment.
