Brief Answer:
Acid reflux

Detailed Answer:
Hello and welcome,

Heartburn is a condition characterized by a burning sensation in the chest or throat, caused by stomach acid flowing back into the esophagus. It is also known as acid reflux or gastroesophageal reflux disease (GERD). Common symptoms of heartburn include a burning sensation in the chest, throat or stomach, a sour or bitter taste in the mouth, difficulty swallowing, and feeling as if food is stuck in the throat.

There are several factors that can contribute to heartburn, including eating large meals or eating certain foods, such as fatty or spicy foods, drinking alcohol or caffeine, smoking, obesity, and pregnancy. Treatment options for heartburn include over-the-counter antacids, prescription medications, and lifestyle changes such as avoiding trigger foods, eating smaller meals, and maintaining a healthy weight. If you experience frequent or severe heartburn, it is important to consult a healthcare professional to rule out any underlying medical conditions and receive appropriate treatment.
