Before trying to cleanse your kidneys

  Articles

Located under the rib cage in the lower back, the kidneys are a pair of bean-shaped organs responsible for removing waste products from your body. Each day, your kidneys process about 200 liters of blood to help remove about two liters of excess water and food waste products and the normal destruction of active tissues.

The kidneys also release three important hormones: erythropoietin (which stimulates the bone marrow to produce red blood cells), renin (regulates blood pressure), and calcitriol (the active form of vitamin D, which helps maintain bone calcium and normal chemical balance. in the body).

What is a kidney cleanse?

If you consume enough fluids, which can take the form of foods like fruits and vegetables, as well as water and other fluids, your kidneys clean themselves.

Various foods, foods, or special diets (commonly sold as kidney cleansers) claim to remove toxins from the kidneys to promote healthy kidney function and prevent kidney stones . Kidney cleanse is also designed to help control blood pressure, improve urinary tract and bladder function, boost immunity , and flush toxins from the entire body.

While the individual components of a kidney cleanse (such as certain herbs, foods, or nutrients) may be beneficial to health, there is no scientific evidence for their use to cleanse the kidneys or prevent kidney stones or infections .

If you are interested in using natural approaches to improve kidney health, speak with your doctor and consider consulting with a qualified complementary or alternative healthcare professional.

Cleaning the kidneys varies in focus. Here are some of the most common types of kidney cleanings:

In many cases, the kidney cleanse includes herbs, vitamins, and minerals in a whole food diet designed to cleanse the kidneys.

Posible problems

While proponents of kidney cleanse suggest that they improve the kidneys' ability to excrete waste from the body, their claims are not supported by scientific evidence. As with other supplements, the Food and Drug Administration (FDA) does not require products marketed to cleanse the kidneys to be safe or effective.

While consumers face such risks when purchasing any supplement, these risks may be greater with supplements that contain various herbs in high doses.

Pregnant or nursing women, children, and people with kidney disease should not try a kidney cleanse. If you plan to use a kidney cleanser or supplement, talk to your healthcare professional first. Avoiding or delaying standard medical care can have serious consequences.
