Coffee increases the risk of calcium kidney stones
Coffee is often used as a "friend" when you are getting too tired and sleepy to get the job done. But, in fact, the caffeine in coffee can affect your entire body's performance, including your kidneys.
In a study published in the Journal of Urology in August 2004, experts found that caffeine consumption increases the risk of kidney stones in kidney stone patients, especially calcium stones. Calcium stones are formed from a combination of calcium and oxalate crystals that cause high levels of calcium in the urine. This type of kidney stone is the most common.
In the study, study participants who had a medical history of calcium kidney stones were given 6 milligrams of caffeine per kilogram of body weight after fasting for 14 hours. As a result, there is an increased risk of calcium kidney stones after consuming caffeine.

Griffin, who was published in the Journal of Human Nutrition and Dietetics in December 2003, found that someone who did not receive caffeine intake for several days, then received a number of caffeine doses equivalent to two to three cups of coffee increased their urine output.
