Caffeine. A common cause of stomach irritation from drinking green tea is its caffeine content. Green tea is not fermented like black tea or oolong tea, so typically it has a lower amount of caffeine, but it can still cause an upset stomach.
The side effects of drinking too much black tea include difficulty sleeping, headaches, nervousness, diarrhea, irritability, irregular heart rate, confusion, heartburn, tremors in your extremities and possibly convulsions. These side effects are all a result of the caffeine content in black tea. If you are used to drinking black tea regularly -- particularly in larger quantities -- you may develop a physical and psychological dependence on the beverage, again, primarily due to the caffeine content.
