Huashan Hospital, Department of Gastroenterology, Attending Physician Cai Chenwen.

On an empty stomach, components in coffee such as caffeine and tannic acid stimulate increased gastric acid secretion, while caffeine also acts directly on the gastric mucosa and lowers its defensive capacity. With no food to neutralise it, the acid comes into direct contact with and damages the stomach lining, easily causing a burning sensation, dull pain and acid reflux. Long-term coffee drinking on an empty stomach may also trigger or worsen chronic gastritis, gastric ulcers and reflux oesophagitis. So we suggest eating something before your coffee — a slice of bread or a few biscuits will effectively buffer the acid and reduce irritation to the stomach. Milk, the golden partner of coffee, contains moderate protein and fat that also help neutralise stomach acid, so it is a good idea to pair milk with your coffee. If you already have a stomach condition, opt for decaffeinated coffee or drink it after meals.
