Can patients with gastritis drink oolong tea?
Generally, patients with gastritis are not advised to drink oolong tea. The detailed explanation is as follows:

Oolong tea contains components such as tea polyphenols and caffeine, which can easily promote the secretion of gastric acid and increase irritation to the gastric mucosa, possibly worsening symptoms such as acid reflux, stomach bloating, and stomach pain. Patients with gastritis often already have inflammation of the gastric mucosa, and drinking oolong tea might further aggravate the damage to the gastric mucosa, delaying recovery from the condition. Additionally, caffeine can stimulate the central nervous system, potentially affecting normal gastric physiological functions and being unfavorable to the patient's sleep quality and overall health condition.
Patients with gastritis should strictly control their diet in daily life, avoiding any foods and beverages that may加重 the stomach's workload. In addition to oolong tea, other stimulating beverages such as coffee and beer should also be avoided. At the same time, spicy, raw, cold, and greasy foods should be consumed sparingly or avoided altogether to prevent further damage to the gastric mucosa.
