Can Acidity Cause Cough?


Yes, acidity can potentially cause or contribute to a chronic cough. This type of cough is often referred to as “acid reflux cough” or “gastroesophageal reflux disease (GERD)-related cough.”

Acid reflux occurs when stomach acid flows back into the esophagus, the tube that connects the mouth to the stomach. This can happen due to a weakened lower esophageal sphincter (the muscle that separates the stomach from the esophagus), allowing stomach acid to travel upwards. When stomach acid reaches the upper esophagus and throat, it can irritate the sensitive tissues, leading to various symptoms, including a chronic cough.

The acid irritates the nerve endings in the esophagus and the throat, triggering a cough reflex. This cough may be dry and persistent, and it often worsens at night when lying down. Other symptoms of acid reflux may also be present, such as heartburn, regurgitation, a sour taste in the mouth, or a sensation of a lump in the throat (globus sensation).

It’s important to note that not all cases of chronic cough are caused by acid reflux. Many other factors can contribute to a chronic cough, including allergies, asthma, postnasal drip, infections, and medications. If you have a persistent or bothersome cough, especially if it’s accompanied by other symptoms, it’s a good idea to consult a healthcare professional. They can help determine the underlying cause and recommend appropriate treatment.
