Too much iced tea can favor kidney stones

Iced tea is a popular soft drink during the hot summer days. However, internists warn against too much iced tea. In addition to the high sugar content, the consumption of commercial or homemade iced tea promotes the formation of kidney stones. This is due to a certain acid that promotes kidney stone formation.

In summer, many people like to drink cold iced tea. But if you tend to build up deposits, you should switch to other beverages, like the chair of the professional association of German internists, Wolfgang Wesiack, warned. The typical summer drink, like all black and green teas, contains oxalic acid (oxalate), the internist reports. If the acid is supplied to the body in large quantities, certain types of kidney stones can develop.

Better water with lemon juice
Iced tea, in particular, is drunk a lot more on hot days than normal tea. "If someone tends to form painful deposits, iced tea should be avoided," advises the doctor. It is better, however, water that is mixed with fresh lemon slices or lemon juice. The acidity of the lemon has a positive influence and prevents kidney stone growth, says the medical specialist.

A lack of fluids favors kidney stones
In summer it can quickly happen that people drink too little fluid. However, lack of fluids is the most common cause of kidney stone formation. According to Wesiack, men from the age of 40 have a four times higher risk than women. From this point on, women who reach menopause also have an increased risk due to the low estrogen hormone level.

Dietary changes can prevent
There are numerous ways to reduce the risk of illness. This is the best way to avoid drinks and foods containing oxalic acid, the doctor advises. Examples include coffee, cola, wheat bran, rhubarb, nuts, spinach and nuts. Food alternatives such as curd cheese, cheese, milk, yoghurt and potatoes are good alternatives. These contain a lot of calcium. Studies had found that the mineral calcium reduced the absorption of acid in the intestine. In addition, sufferers should avoid excessive consumption of fat and table salt. Obesity and calcium deficiency are also risk factors for kidney stones.

Severe pain in kidney stones
Kidney stones are mostly noticeable by severe flank pain and discomfort when urinating. If the stones get into the ureter, they can get stuck at the narrow points. Fixing causes severe and undulating pain (renal colic). In many cases, blood is visible in the urine or at least detectable in the laboratory. In most cases there is a urine congestion and the kidney affected can be damaged. If the stones are very small, they can come off without kidney pain. In addition to drug therapy, minimally invasive procedures are also carried out. In naturopathy, teas with dandelion roots and real bedstraw are also used. These are said to help dissolve the kidney stones. (sb)
