Stomach acid and acid reflux are two common digestive ailments. While both conditions are characterized by a burning sensation in the chest and abdomen, they have distinct differences.
Stomach Acid
Stomach acid is a natural fluid that is produced by the cells in the stomach to help break down food. It is composed of hydrochloric acid and is highly acidic, with a pH range of 1.5 to 3.5. Stomach acid helps to digest food by breaking it down into smaller pieces that can be absorbed by the body.
Acid Reflux
Acid reflux is a condition in which stomach acid flows back up into the esophagus. This can cause a burning sensation in the chest and throat, as well as other symptoms such as difficulty swallowing, coughing, and a sour taste in the mouth. Acid reflux is often caused by a weakened lower esophageal sphincter, which allows stomach acid to flow back up into the esophagus. Treatment for acid reflux may include lifestyle changes, medications, or surgery.
