Which Type Of Tea Causes Kidney Stones

Does matcha green tea cause kidney stones? / Kidney Stone Diet Podcast with Jill Harris

Now, after knowing that green tea prevents the formation of kidney stones, you might be thinking that the effect is the same with other tea varieties as well. Arent you?

However, this is not true!

There are teas that cause kidney stones. Those who already suffer from kidney stones are not supposed to drink tea. This is because tea contains a high amount of oxalate that leads to the formation of kidney stones.

If you consume too much tea you can end up with kidney stones.

Now, as already discussed, green tea has a preventive effect with regard to kidney stones and this shows that not every tea causes them. It all depends on the oxalate level of tea.

When compared to green tea, black tea has a higher amount of oxalate present in it and therefore should be avoided.

P.S. It is still not very clear whether by bringing down your consumption of oxalate-rich foods you can prevent kidney stones or not. So, those with a history of kidney stones need to limit their consumption of food and drink that has more amount of oxalate.

You can always drink green tea as the amount of oxalate in it is quite less when compared to that of black tea.

What Are Kidney Stones

If you have ever watched a program where a member of the cast had kidney stones, then you know one thing: they are painful. These stones are hard deposits that form inside your kidneys comprising minerals and salts.

They can come about due to many factors, including medical conditions, some meds, a poor diet, obesity, and using supplements. These stones are not specific as to the area in which they form. They can do so on any part of the urinary tract from the kidneys to the bladder. A risk factor is when the urine concentration is high such that minerals find it easy to crystallize and bind.

Having them is not usually much of a problem until you have to pass them, which is an excruciating experience. The good thing is that they will not cause much harm as long as you discover them in the early stages. The ease of passing them depends on their state.

Some can come out on their own as long as you drink a lot of water and take some meds. Others require medical interventions such as surgery, more so where other complications are in play. If you have had kidney stones, the doctor will recommend some practices and treatments to prevent the reoccurrence of the same.

What Tea Is Low In Oxalate

If youre a tea lover whos concerned about oxalate, the good news is that virtually all tea is low in oxalate when taking into account the serving sizes compared to common foods.

Furthermore, data show that oxalates in tea do not appear to increase urinary calcium or urinary oxalate excretion , making them less likely to result in kidney stones than other sources.

But perhaps your doctor has advised against drinking tea, or youre intent on avoiding oxalates to the greatest extent possible.

If so, you can use this list of tisanes shown in scientific research to be extremely low in oxalates:

Iced Tea Can Contribute To Painful Kidney Stones

Summary:
Summer is the peak season for drinking iced tea, but the popular drink can contribute to painful kidney stones. Iced tea contains high concentrations of oxalate, one of the key chemicals that lead to the formation of kidney stones.

This is the peak season for drinking iced tea, but a Loyola University Medical Center urologist is warning the popular drink can contribute to painful kidney stones.

Iced tea contains high concentrations of oxalate, one of the key chemicals that lead to the formation of kidney stones, a common disorder of the urinary tract that affects about 10 percent of the population in the United States.

“For people who have a tendency to form the most common type of kidney stones, iced tea is one of the worst things to drink,” said Dr. John Milner, assistant professor, Department of Urology, Loyola University Chicago Stritch School of Medicine.

The most common cause of kidney stones is not drinking enough fluids. And during the summer, people can become dehydrated from sweating. Dehydration, combined with increased iced tea consumption, raises the risk of kidney stones, especially in people already at risk.

“People are told that in the summertime they should drink more fluids,” Milner said. “A lot of people choose to drink more iced tea, because it is low in calories and tastes better than water. However, in terms of kidney stones, they might be doing themselves a disservice.”

As we previously mentioned, kidney stones come in all different shapes and sizes. While the average kidney stone is five millimeters in length, there have been ones that are bigger. Someone whos suffering from a larger kidney stone might find it stuck in their ureter. Healthline points out that this could cause even more problems, such as slowing or stopping the flow of urine.

If you find that you are unable to urinate or that its only happening in small amounts at a time, go see a doctor immediately.

What Kind Of Tea Causes Kidney Stones

Doctor John Milner from Loyola University Medical Center echoed in his research that many people drink iced tea when it’s hot out, but there is a very big problem with that: iced tea and flavored tea contain oxalate.

Besides being bad for your teeth, oxalate can be very dangerous. A high level of oxalate may contribute to the formation of kidney stones – which are painful, and more importantly previously fatal.

Even if you haven’t already experienced pain in this area, the chances are high that you will eventually develop the condition. Bladder stones in general affect about 10 percent of the population in the United States.

Also, while there’s any much medical research available on it, people of all ages who sweat too much while drinking iced tea should be significantly aware.

Kidney stones affect about 5% of the worlds population. They occur whenabnormally high concentrations of minerals, such as calcium, accumulate in theurinary tract and clump together to form crystals and potentially painfulstones.

Most kidney stones contain calcium, and the most common stone type iscalcium oxalate. Chinese researchers found that green tea extract bonds tocalcium oxalate and makes the resulting crystals a different shape, which makesthem less likely to clump together and form large kidney stones.

The smaller crystals and stones are then passed harmlessly through theurine.

In the study, published in CrystEngComm, Xudong Li of SichuanUniversity in Chengdu, China, and colleagues examined the effects of green teaconcentrate on calcium oxalate crystallization using a variety of advancedscanning and imaging techniques.

The results showed that as the amount of green tea extract appliedincreased, the calcium oxalate crystals became flatter and flatter.

Researchers say flatter crystals form less stable kidney stones that breakup more easily.

Passing a kidney stone is often described as one of the most painful experiences a person can have, but unfortunately, it’s not always a one-time event. Studies have shown that having even one stone greatly increases your chances of having another. “Most people will want to do anything they can to ensure it doesn’t happen again,” said Dr. Jhagroo. “Unfortunately, it doesn’t seem to be the case that people make the changes they need to after their first stone event.”

Research conducted by Dr. Jhagroo shows that those with kidney stones do not always heed the advice of their nephrologists and urinary specialists. About 15% of kidney stone patients didn’t take prescribed medications and 41% did not follow the nutritional advice that would keep stones from recurring. Without the right medications and diet adjustments, stones can come back, and recurring kidney stones also could be an indicator of other problems, including kidney disease.

Treatment For Large Stones

Not all kidney stones can pass naturally through the urinary tract. Some can be too big, which can block the flow of urine. Doctors can break down the stones either by using sound waves, or inserting a tube with a camera through the urethra and using tools. This will allow the patient to later pass the smaller pieces through their urine. Alternatively, other patients may require surgery to directly remove stones from the kidney.

It’s Not Just The Oxalate

Oxalate is naturally found in many foods, including fruits and vegetables, nuts and seeds, grains, legumes, and even chocolate and tea. Some examples of foods that contain high levels of oxalate include: peanuts, rhubarb, spinach, beets, chocolate and sweet potatoes. Moderating intake of these foods may be beneficial for people who form calcium oxalate stones, the leading type of kidney stones.

A common misconception is that cutting the oxalate-rich foods in your diet alone will reduce the likelihood of forming calcium oxalate kidney stones. While in theory this might be true, this approach isn’t smart from an overall health perspective. Most kidney stones are formed when oxalate binds to calcium while urine is produced by the kidneys.

It is important to eat and drink calcium and oxalate-rich foods together during a meal. In doing so, oxalate and calcium are more likely to bind to one another in the stomach and intestines before the kidneys begin processing, making it less likely that kidney stones will form.

Iced Tea May Cause Kidney Stones

Summer is high season for drinking iced tea. However, a John Miller, Loyla University Medical Center urologist warns that iced tea can contribute to painful kidney stones because of its high concentration of oxalate, one of the key chemicals that lead to the formation of kidney stones.

Around 10% of people in the U.S. suffer from kidney stones, a common disorder of the urinary tract.

Dr. John Milner, assistant professor at the Department of Urology at Loyola University Chicago Stritch School of Medicine explains: For people who have a tendency to form the most common type of kidney stones, iced tea is one of the worst things to drink.

Drinking an insufficient amount of fluids is the most common cause of kidney stones, and during the summer, when people can become dehydrated from sweating, the combined effect of dehydration together with drinking a lot of iced tea can raise the chance of developing kidney stones, particular in those already at risk.

Milner said:

Even though hot tea also contains oxalate, Milner said that it is difficult to drink sufficient amounts to cause kidney stones and figures from the Tea Association of the USA reveal that around 85% of tea consumed in the United States is iced.
