The body produces many harmful metabolic toxins every day, and the kidneys are the detoxification organ. 98% of the metabolic toxins in the body need to be excreted by the kidneys, while the remaining toxins are eliminated by the skin and respiratory tract (lungs). The smell of urine is heavy, under physiological conditions, it means that the kidney detoxification function is normal, especially when the body is dehydrated urine volume is reduced, this situation is not necessary to make a fuss. In pathological conditions, the heavy smell of urine often indicates urinary retention, bladder stones or tumors.
