Coffee can irritate the stomach to produce excess acid. Some individuals may experience a burning sensation or an upset stomach.

Caffeine can also make the lower oesophageal sphincter relax. This is the muscle which prevents the stomach acid from returning to the oesophagus. This can be a cause of acid reflux in sensitive individuals.

Some people may also experience:

• Nausea
• Stomach cramps
• Burning
• Bloating or discomfort

However, people aren't all affected by these effects.

Can Black Coffee On An Empty Stomach Cause Acidity?

In some individuals, especially people who are sensitive to stomach acid, coffee could aggravate the acidity or reflux symptoms. A 2022 review published in Nutrients found that coffee can stimulate the production of stomach acid and gastrin, which are involved in digestion. However, its effect on acid reflux is less clear. 

Some studies found that coffee may worsen reflux symptoms, while others found no significant link. The review also noted that most research did not show coffee increasing the risk of peptic ulcers. The researchers highlighted that individual responses can vary. Factors such as the type of coffee, roasting, preparation and whether it is consumed with food may influence its effects.

• Acid reflux or GERD, as morning coffee may worsen symptoms.
• Sensitive stomach or gastritis, which can be more noticeable, causing discomfort.
• Caffeine might seem more potent if consumed without food, and can lead to anxiety or jitteriness.
• Getting regular heartburn or bloating from coffee, which may be an individual warning sign that they aren't getting the right type of coffee.

If the symptoms return regularly after coffee, then consider trying cold coffee, coffee with food or changing the time of day you drink it.
