Drinking matcha does not usually give you diarrhea, but it can if you suffer from chronic gastritis, peptic ulcers, and other diseases.
Matcha is a food made from tea leaves, which contains stimulating ingredients such as tea polyphenols, theophylline and caffeine. In good health, the gastrointestinal tract can tolerate it, and drinking matcha usually does not cause diarrhea.
But there are cases of diarrhea. If you suffer from chronic gastritis, your intestines become sensitive due to the presence of inflammation in the intestines. Once you drink matcha, the ingredients it contains will stimulate the intestines, leading to faster intestinal peristalsis and diarrhea.
If you suffer from peptic ulcer, after drinking matcha, the ingredients it contains will stimulate the ulcer surface, leading to faster intestinal peristalsis and diarrhea.
Matcha is a food, but it should be consumed in moderation and according to the situation. Avoid excessive or improper consumption, which can cause discomfort.
