Can Green Tea Cause Kidney Stones?

Green tea is renowned for its health benefits, however, some people may be unaware that in certain cases, drinking too much of it could cause kidney stones. Here is an overview of the potential danger of too much green tea.

What Causes Kidney Stones?

Kidney stones are caused by a number of factors including dehydration, high levels of certain minerals, such as calcium or oxalate, and acidity in the urine. When levels of calcium or oxalate increase, they combine to form stones.

Is Green Tea High in Oxalates?

Green tea contains oxalates, though not in high concentrations. Therefore, drinking green tea doesn’t usually increase the risk of kidney stones. However, if green tea is drunk in large quantities, it can lead to an increase in oxalate levels, which can then lead to an increased risk of kidney stones.

What Are the Symptoms of Kidney Stones?

Kidney stones can cause a range of symptoms, such as:

  • Pain: Pain may be felt in the side or lower back.
  • Nausea: Vomiting may occur.
  • Blood in the Urine: Pink or red-tinged urine may be present.
  • Frequent Urination: An urge to urinate may occur.
  • Fever and Chills: Fever and chills may occur.

How Can I Avoid Kidney Stones?

To reduce the risk of developing kidney stones, it is important to:

  • Keep well hydrated and drink at least 8 glasses of water per day.
  • Limit consumption of foods high in oxalates such as spinach, rhubarb, and beets.
  • Limit consumption of salt and animal protein.
  • Limit consumption of green tea, as it can contain high levels of oxalate.

In conclusion, while green tea can help to improve overall health, it is important to be aware of the potential risk of kidney stones associated with drinking too much of it. Therefore, make sure to keep an eye on your consumption and speak to your doctor if you have any concerns.
