Too much caffeinated drinks are prone to kidney stones?

Drinking too many caffeinated drinks can lead to kidney stones, a new study has found.

Surveys show that when people drink too much caffeinated drinks, the amount of calcium in their urine increases significantly, making them more likely to develop stones.

Specialists say calcium is the main component of stones. If you take more caffeine, the risk is even greater. The study involved 39 people who had kidney stones and 9 people who had never had kidney stones. These people were asked to fast for 14 hours before the experiment. The subjects then examined their urine samples two hours before and after drinking caffeinated drinks.

In both groups, urine samples showed increases in calcium, sodium, magnesium and citrate levels. This is because magnesium and citrate in the body can help prevent the formation of kidney stones. However, after drinking caffeinated drinks, these are also excreted from the body, increasing the risk of lithiasis.
