Normal people urinate about 5 to 7 times a day, but the number of times they urinate varies from person to person and there is no uniform standard due to the different physical condition of individuals and their different water intake and dietary habits. When blood flows through the glomeruli, uric acid, water, glucose and other substances in the blood will be filtered through the glomeruli into the renal peritoneum to form primary urine. At this time, the primary urine will be reabsorbed by the renal tubules, and the remaining water, inorganic salts, uric acid, etc. will form urine. Normal human body each day and night to discharge about 1 to 2 liters of urine, and the normal capacity of the bladder is about 300 to 500 milliliters, so the number of normal people during the day to urinate about 4 to 6 times, the number of times at night to urinate about 1 to 2 times. In addition, drinking a lot of water can also cause an increase in the number of times of urination. The blood flow rate of the human body decreases during sleep, which leads to slower formation of urine, so the number of times of urination at night is less, and these are all normal phenomena. If symptoms such as frequent urination and urinary urgency occur, it is recommended to go to the hospital to receive a doctor’s diagnosis, to clarify the cause of the disease and timely treatment.
