Why does drinking green tea recently cause stomach pain?

Possible reasons for stomach pain caused by drinking green tea: 1. Green tea has a slightly cold nature. If you have a condition of spleen and stomach deficiency-coldness, drinking green tea might exacerbate the coldness in the stomach, leading to discomfort or pain. 2. Components in green tea such as polyphenols may irritate the gastric mucosa, especially when consumed on an empty stomach or in excessive amounts, making this sensation more pronounced. 3. If you already suffer from gastric diseases such as gastritis or peptic ulcer, drinking green tea might worsen the symptoms of these conditions, causing stomach pain. Therefore, it is recommended to drink green tea in moderation, avoid drinking it on an empty stomach or in excessive quantities, and individuals with spleen and stomach deficiency-coldness or gastric diseases should be particularly cautious.
