Drinking beer to appear less urine does not mean that the kidneys are not good to appear this situation, it may be related to the food eaten more salty, or drink less beer and so on. Some people drink more beer, there will be more urine, the general human body fluid intake and discharge is basically in a dynamic state of equilibrium, the human body 24 hours a day, the amount of urine in the 1000-2000ml or so. If the amount of urine is too little or too much urine, generally not normal. If the vegetables and fruits eaten while drinking beer are less, the liquid content contained in the food will be less, and the urine that appears will be less, but this situation does not mean that the kidney function is not good, so do not need to worry too much.
