Drinking more and urinating more is not a sign of bad kidney, rather it may be a sign of good diuretic function of the kidney. Drinking more alcohol will provide the body with a lot of water, and the large amount of water entering the kidneys through the blood circulation will result in more urine. High concentration of alcohol has diuretic function, so it will lead to the effect of hypertonic diuresis, resulting in the excretion of more water. If the kidneys are bad it is impossible to excrete this water, confirming from the other side that it is not bad kidneys. The most important manifestation of bad kidneys is the reduction of urine volume, the small amount of urine is urea nitrogen, creatinine a lot of elevated, the body can not excrete the toxins out. It is recommended to drink less alcohol and more water, which is the best diet health standard control.
