Why does green tea make you nauseated and hungry?

Nausea:

Green tea contains caffeine, which can cause nausea in some people. Caffeine can stimulate the gastrointestinal tract, leading to an increase in stomach acid production and muscle contractions. This can irritate the stomach and cause nausea. Additionally, green tea contains tannins, which can also irritate the stomach and contribute to nausea.

Hunger:

Green tea contains a compound called epigallocatechin gallate (EGCG), which has been shown to increase metabolism. This can lead to an increase in energy expenditure, which can make you feel hungry. Additionally, green tea can suppress the release of ghrelin, a hormone that stimulates hunger. This can also contribute to feelings of hunger after drinking green tea.

It's important to note that not everyone experiences these side effects from green tea. Some people may find that they can tolerate green tea without any problems, while others may need to limit their intake or avoid it altogether. If you are experiencing nausea or hunger after drinking green tea, you should talk to your doctor to rule out any other underlying medical conditions.
