Drinking coffee on an empty stomach is a topic of debate, with mixed opinions about its effects on cortisol levels and gut health. Some social media claims suggest it could harm the gut lining and spike cortisol, but experts have differing views.
Cortisol, a steroid hormone produced by the adrenal glands, plays a role in stress response regulation. The Cleveland Clinic notes that cortisol levels naturally peak in the morning, which some might confuse with a coffee-induced spike. However, studies indicate that drinking coffee on an empty stomach does not significantly affect cortisol or cause serious metabolic issues.

According to Dr. Asma Khapra, a gastroenterologist at GastroHealth, consuming coffee on an empty stomach isn’t inherently harmful. Gastroenterologists dispute the notion that it leads to a significant increase in cortisol levels.
Caffeine affects the muscular valve between the esophagus and stomach, potentially allowing stomach acid to move into the esophagus and cause heartburn. Regular and decaf coffee stimulate stomach acid and gastrin release, which can cause symptoms like nausea or abdominal burning, as noted by Dr. Douglas Weine.
Caffeine also stimulates the central nervous system, possibly raising blood pressure and heart rate, leading to anxiety or sleep disruptions. Individual sensitivity to caffeine varies, affecting how the body responds when coffee is consumed without food.
The Cleveland Clinic confirms that coffee and caffeine are absorbed more rapidly on an empty stomach, but most healthy adults experience no severe side effects. Dr. Khapra advises that a morning coffee sans extensive additives like cream or sugar is acceptable.
