Spicy foods are known to trigger or worsen symptoms of acid reflux in many individuals. Acid reflux, also known as gastroesophageal reflux disease (GERD), occurs when stomach acid flows back up into the esophagus, causing a burning sensation and discomfort in the chest (heartburn).

Here’s why spicy foods can contribute to acid reflux:

1. Capsaicin: Spicy foods contain capsaicin, a compound responsible for the hot and spicy sensation. Capsaicin can irritate the esophagus and lower esophageal sphincter (LES), the muscle that acts as a barrier between the stomach and esophagus. When the LES weakens or relaxes, stomach acid can flow back up, leading to acid reflux symptoms.
2. Increased stomach acid production: Spicy foods may stimulate the production of stomach acid, which can exacerbate acid reflux symptoms. Higher levels of stomach acid increase the likelihood of acid reflux episodes.

If you have acid reflux or are prone to heartburn, it’s generally advisable to avoid or limit consumption of spicy foods. However, individual tolerances may vary, and some people may be more sensitive to certain spices than others.
