Caffeinated beverages are typically recommended to limit for individuals dealing with gastroesophageal reflux disease (GERD) due to the effects of caffeine on the lower esophageal sphincter (LES). The LES is a muscle that acts as a barrier between the stomach and the esophagus. Caffeine can relax this muscle, potentially allowing stomach acid to escape into the esophagus and trigger symptoms such as heartburn.

In addition, caffeinated beverages like coffee and certain teas may also increase gastric acid secretion, further exacerbating GERD symptoms. Therefore, limiting the intake of these beverages is often advised in dietary plans for managing GERD.

Dietary advice for GERD frequently promotes foods that are less likely to cause irritation or increase acid production, while also recommending avoidance of factors that can weaken the LES or stimulate acid secretion, such as caffeine.
