Link Between Tea Consumption and Kidney Stones

Tea is often noted as a cause of kidney stones, but there is a bit more to this accusation than people realize. Drinking a lot of tea or downing several glasses in one sitting can increase yo/treatments/how-to-get-rid-of-kidney-stones-naturally-and-fastur risk of stones, as can drinking specific types of tea that have been proven to increase this risk as well.

Why Tea May Be Dangerous

A kidney stones diet often advises patients to cut tea from their regular eating habits, but there are some conditions that can make this beverage more dangerous.

  • Doctors recommend that those managing a kidney stone avoid tea because it is high in oxalate, a mineral that can cause calcium stones to develop.
  • Calcium stones are some of the most common, which means that precautions for this type of stone are more important than others.
  • People often make the mistake of increasing their amount of tea consumed because if they are at risk for developing stones they need to increase their liquid intake, and tea is known for helping your overall health.

In reality, people that develop calcium stones should make a point of getting more water, compared to any other beverage. Some also say that fresh squeezed lemonade that is not from powder or concentrate can increase citrates in your blood that can help dissolve these stones.

Iced Tea May Cause an Additional Risk


Kidney stones are more common when people drink a great deal of iced tea, compared to the hot variety.

  • People often drink iced tea when it is hot and they are already somewhat dehydrated, which will further increase the concentrations of oxalate in the blood stream.
  • Around 85 percent of the tea served in the United States is iced instead of hot, and it is much easier for the body to absorb oxalate from the iced variety.
  • An essential part of kidney stone prevention is drinking this tea in moderation, though people that are at a very high risk for developing stones will likely need to forgo this drink all together in order to reduce their risk.

Tea is not the only food that contains high levels of oxalate that can lead to a calcium stone. Reducing high calcium or oxalate foods like chocolate, spinach or nuts may also be essential to reducing the risk of stones.

Your doctor can provide you with a full list of dietary tips if you are at risk for this condition.

Sweet Tea is Another Culprit

Causes of kidney stones may also sit at a very high level of sweet tea.

  • Kidney stones are very common in the Southern United States, particularly in the Southeast where sweet tea is a very common beverage. Some doctors have taken to referring to this area as ‘the Stone Belt’ because of this phenomenon.
  • Not only is sweet tea served cold, which increases the amount of oxalate: this beverage is very high in crystallized sugar which can contribute to stone formation as it is processed.
  • Those that are diabetic or obese are at a much higher risk for developing stones, and consuming beverages like sweet tea with a high amount of processed sugar added will contribute to this phenomenon.

It is not necessarily true that people at risk for stones will need to completely avoid drinking tea. You will simply need to ensure that you do not drink high amounts of this beverage, especially in one sitting.
