What causes dizziness after having three cups of green tea?

default
Posted on Sat, 16 May 2015
Question: I had three cups of green tea over the course of six hours. After the last cup I immediately felt dizzy and nauseous. This feeling has not stopped for the past two days. I went to the doctor and he diagnosed me with gastoentisitis, which I do not think it is and the medication does not help. Could it be the tea and how can I overcome feeling so miserable?

Detailed answer...
Hello,
Thanks for the query.
I have read your query and understand your concern.
Although consuming green tea is considered a safe and healthy practice but it can still cause side effects in few individuals.
Green tea contains TANNINS which can cause acidity and stomach pain especially if taken on empty stomach
Similarly green tea also  has caffeine in it,although less than black tea,which if taken in excess can cause side effects like ...vomiting, diarrhoea,nervousness,dizziness,irritability etc.
These side effects of green tea generally go off in a day or two and hence you should wait and watch as you should be about to get all right.
Take PANTOPROZOLE 40 mg once day on empty stomach in morning for 5-7 days and your gastritis ( acidity ) should be all right.
I would be highly surprised if your symptoms don't improve in next 24-48 hours.
By the way,if these symptoms persist beyond another 48 hours,you would need to see a doctor to look for the cause.
Take plenty of water,lemon water and coconut water to rehydrate you and flush your system.
I hope it helps,however you are most welcome to revert to me for any further query.
Best of luck
Thanks
