Hello Mrs.
Lin, tea can be somewhat stimulating.
If you experience stomach discomfort when consumed on an empty stomach, it is advisable to drink it after meals and undergo a gastroscopy.

More Info


Drinking green tea on an empty stomach has been a topic of discussion among health enthusiasts and medical professionals alike. While many people, like yourself and your husband, have enjoyed this practice for years without apparent adverse effects, it is essential to consider the potential implications for your health.

Green tea is rich in antioxidants, particularly catechins, which are known for their health benefits, including anti-inflammatory and anti-cancer properties. However, it also contains caffeine and tannins, which can have a stimulating effect on the gastrointestinal tract. When consumed on an empty stomach, these compounds may lead to discomfort for some individuals.
For many, drinking green tea first thing in the morning can cause symptoms such as stomach upset, nausea, or even acid reflux. This is primarily due to the acidity of the tea and the presence of tannins, which can irritate the stomach lining when it is empty. If you or anyone else experiences any of these symptoms, it may be advisable to switch to drinking tea after meals or to consider consuming a less concentrated form of tea.

Moreover, the caffeine content in green tea, while lower than that in coffee, can still stimulate gastric acid secretion. For individuals with pre-existing gastrointestinal conditions, such as gastritis or peptic ulcers, this could exacerbate symptoms. Therefore, if you have a history of such conditions or experience any discomfort, it would be wise to consult with a healthcare professional.

On the other hand, if you and your husband have been drinking green tea for decades without any negative effects, it suggests that your bodies may have adapted to it. Individual tolerance to caffeine and other compounds in tea can vary significantly. Some people can consume caffeinated beverages on an empty stomach without any issues, while others may find it uncomfortable.

In terms of health benefits, moderate consumption of green tea is generally considered safe and can be beneficial. The key is moderation; excessive consumption of green tea can lead to adverse effects, including insomnia, increased heart rate, and digestive issues. It is recommended that individuals limit their intake to about 3-4 cups per day, depending on their tolerance to caffeine.

For pregnant women, the consumption of green tea should be approached with caution due to its caffeine content. While moderate amounts are generally considered safe, it is advisable to limit intake to avoid potential risks to the fetus.

In conclusion, while drinking green tea on an empty stomach may not pose a significant risk for everyone, it is essential to listen to your body. If you experience any discomfort, consider adjusting your routine to include food before tea or reducing the concentration of the tea you consume. Always consult with a healthcare provider if you have specific health concerns or conditions that may be affected by your dietary choices. Your long-standing habit of drinking green tea is commendable, but being mindful of how it affects your body is crucial for maintaining your health in the long run.
