A teen girl has developed acute hepatitis because of drinking green tea in excess to lose weight. Doctors have used her case to demonstrate the dangers of consuming too much green tea.

The unnamed girl fell ill with a kidney infection after she followed a three-month diet that included three cups of hot green tea each day. She went to her GP, complaining about dizziness, nausea, stomach and joint pains, and her GP prescribed antibiotics for a urinary infection.

But the girl's symptoms got worse after two days and she went to the A&E unit of Birmingham University Hospital. There doctors told her that she was suffering from jaundice.

The teen told the doctors that she didn't consume alcohol, drugs or any kind of medication that could lead to the hepatitis virus. But, she mentioned about her three-month green tea binge.

She said, "I had bought green tea over internet to lose weight. Most of the ingredients of tea I bought were written in Chinese. I had only lost 2 pounds but then started having pains in my joints, felt very dizzy and sick".

Doctors ordered her to stop drinking the tea, and they noticed that the teen subsequently started making a quick recovery. The British Medical Journal reported that infections caused due to excessive tea drinking are an 'uncommon but recurring theme'.

Green tea is said to have amazing health benefits, but experts have warned that some brands may add pesticides in the products that must not be consumed in excess.

Green tea is made from the leaves from Camellia sinensis that have undergone minimal oxidation during processing.

The report said "There is potential for pesticide-induced hepatitis to exist, especially from less regulated products ordered from developing countries over the internet. We acknowledge that green tea is predominantly a very safe and healthy drink, with antioxidant properties."
