Drinking Coffee on an Empty Stomach: What Experts Say About Health Risks
Gastroenterologists clarify that drinking morning coffee on an empty stomach is safe for most, though sensitive individuals may experience heartburn or nausea.
Morning coffee before breakfast is a daily routine for many, though social media claims suggest it harms the digestive system and spikes cortisol levels. However, gastroenterologists clarify that for most individuals, the habit is not dangerous and lacks definitive scientific backing for significant health risks.
A primary concern is the increase in cortisol, but experts note that levels of this stress hormone naturally peak in the morning regardless of coffee consumption. Coffee, including decaffeinated varieties, stimulates the release of stomach acid and the hormone gastrin, which regulates digestion. This process occurs normally, though without food in the stomach, it may become more pronounced for certain individuals.
For sensitive people, this habit can trigger unpleasant symptoms. Caffeine relaxes the lower esophageal sphincter, potentially allowing stomach acid to rise and cause heartburn. Without food to absorb some of the acid, sensations such as nausea or abdominal burning may occur. Additionally, caffeine can elevate blood pressure and heart rate, triggering anxiety or palpitations in sensitive populations.
Experts emphasize that the ultimate takeaway is to listen to your body. If negative symptoms like heartburn or nausea are absent, there is no medical reason to alter the morning routine. Those experiencing discomfort should consider consuming coffee following a small meal, as caffeine sensitivity varies significantly among individuals.
