Although experts agree that green tea is the best type of tea, due to its many health benefits, excessive consumption of it may cause serious harm.
Green tea is known for being rich in antioxidants, which help reduce inflammation and protect against chronic diseases.
The health news website Verywell Health listed six serious side effects of excessive green tea consumption :
Gastrointestinal disorders
Generally, most people can drink green tea safely without problems, but taking supplements made from green tea may cause stomach upset, nausea, and constipation.
high blood pressure
Tea contains high levels of caffeine, and excessive consumption can cause side effects such as high blood pressure, rapid heartbeat,
headache, anxiety, and sleep difficulties.
Sleep problems
Large amounts of caffeine may affect sleep quality, and it is advisable to avoid drinking tea hours before bedtime.
Poor iron absorption
Green tea contains plant compounds called catechins, which are antioxidants. Despite their health benefits, they affect the body's ability to absorb iron, which may lead to iron-deficiency anemia, especially in people who are already deficient.
It is advisable to consult a doctor if levels of this mineral are low, and to limit yourself to small amounts of tea to reduce this effect.
Liver problems
People who carry a certain type of gene can develop liver damage from drinking green tea.
This often happens with people who consume green tea extracts, not the tea itself.
Drug interactions
Green tea, when consumed in large quantities, may interact with some medications , affecting their components or reducing their effectiveness.
This is common when taking green tea supplements, but it can also happen with tea itself when consumed in excess.
It is advisable to visit a doctor before consuming green tea if you are taking medications such as blood thinners, cholesterol medications, anti- inflammatories , and osteoporosis treatments.
Green tea is not for everyone
It is advisable to avoid green tea in the following cases:
It can cause anemia, because the compounds in tea increase the risk of iron deficiency.
Liver problems, as large quantities may cause liver damage.
During pregnancy, it is advisable to consult a doctor to determine the safe amount during pregnancy and breastfeeding.
When suffering from caffeine sensitivity.
