Matcha is a tea beverage made from finely ground green tea powder, known for its rich tea aroma and unique taste. Although matcha offers numerous health benefits, it may cause diarrhea in certain circumstances, such as high caffeine content, high fiber content, high levels of tea polyphenols, or due to individual differences. Drinking excessive amounts of matcha can easily stimulate gastric acid secretion, leading to excess stomach acid and damaging the gastric mucosa, which may result in diarrhea. If diarrhea occurs after consuming matcha, it is recommended to drink plenty of water to replenish lost fluids and electrolytes, preventing dehydration, and to get adequate rest to support recovery.

If diarrhea develops after drinking matcha, it is advisable to moderately reduce matcha intake and observe whether symptoms improve. If diarrhea persists or becomes severe, medical consultation is recommended to obtain professional advice. Additionally, individuals with sensitive digestive systems should moderate their matcha consumption and avoid overconsumption as a preventive measure against diarrhea.
