What does healthy urine look like?
Urine color: light yellow and transparent. Xu Qingquan, chief physician of urology department of Peking University People's Hospital, pointed out that healthy urine should be light yellow and transparent, without precipitation or turbidity. However, many factors will affect the color of urine, such as water consumption, changes in body temperature and the role of food and drugs. When drinking more water, urine may be as colorless as boiled water; When you drink less water and sweat more, your urine may turn yellow like beer, which is normal.
Number of urination: no more than 8 times a day. Yong Yang, director of urology department of Peking University Cancer Hospital, told the reporter of Life Times that theoretically, a person should not urinate more than eight times a day. Seven times during the day and 1 time at night, which is the best ratio. "But it is normal for everyone to urinate 4-6 times a day because they drink differently." Xu Qingquan added that it is best not to urinate more than twice at night. If you drink more water before going to bed, it is normal to get up at night. But if you don't drink much water at night, but you always get up at night, you should pay attention to your illness.
Urine volume: daily 1500ml. Our daily urine output should be around 1500ml, but as long as the daily urine output is above 400ml and below 3000ml, there is no problem. Xu qingquan, an expert in urology, reminded that less than 400 ml of urine a day is a sign of oliguria; More than 3000 ml is polyuria.
Male: Squeeze perineum downward after urinating.
It is best to pee standing up. Professor Jiang Hui, chairman of the andrology branch of Chinese Medical Association and director of the andrology clinic of Peking University Third Hospital, said that men had better urinate standing up because their urethra is S-shaped. When standing up, urine can be naturally excreted because of the influence of gravity. If you urinate sitting down, the urethra will become barbed. After being pressed, it will cause pelvic congestion, and urine is relatively difficult to discharge. And after a long time, the bladder and urethra may become inflamed. Squatting to urinate will change the urethral pressure, and urine may flow back to the bladder, which is easy to induce inflammation.
Don't sit down immediately after urinating. Jun Guo, chief physician of andrology in Xiyuan Hospital, Chinese Academy of Traditional Chinese Medicine, pointed out that if a man sits down immediately after urinating, it will cause residual urine to flow back, giving bacteria in the urethra an opportunity and easily inducing prostatitis. After urinating, squeeze your fingers at the perineum between scrotum and anus. This is helpful to discharge the residual urine in the bladder and is also beneficial to the treatment of chronic prostatitis.
Strong urination doesn't mean strong ability. Many men measure their sexual ability by the sound, intensity and duration of urination. Actually, the two have little to do with each other. Sexual ability largely depends on the hardness and endurance of penis erection, which is related to the blood microcirculation of penis and has nothing to do with the performance of urination.
Don't worry about the occasional urinary fissure. The occurrence of urinary bifurcation is mainly due to obstruction of urethra or urethral orifice. For example, holding your urine will increase the pressure on your bladder. When urinating, it is easy to temporarily change the shape of the urethral orifice, resulting in urinary bifurcation. In after ejaculation, part of semen remains in the urethra, and the erection does not completely disappear. Men will have urinary fissure. Both of the above conditions are normal, but if there is persistent high-frequency urinary bifurcation, you should go to the hospital for examination.
W: Don't wipe your private parts with a wet tissue.
Dry after urinating. Sun, director of the Department of Gynecology of beijing jishuitan hospital, reminded that women have deeper and more wrinkles in their private parts. After urinating, if it is not dried in time, the residual urine will make underwear very wet, which provides a hotbed for bacterial reproduction. "When wiping, be sure to wipe it from front to back with clean toilet paper. It is best not to use wet paper towels. " Sun explained: first, many wet tissues are added with chemical components, which is not good for the health of women's private parts; Second, after wiping with a wet paper towel, there will still be wet problems.
Wash your hands before and after urinating. Compared with men, female urinary system is more fragile. The female urethra is very short and closely connected with the bladder. External bacteria can easily enter the bladder along the urethra, causing urinary tract infection or inflammation. Therefore, women should wash their hands before and after urinating, and don't give bacteria an opportunity.
Learn to maintain and keep the urinary tract unblocked. According to the statistics of the World Health Organization, the incidence of urinary tract infection in women is 8- 10 times higher than that in men. In order to make the urinary tract more unobstructed, women should pay attention to maintenance. Gynecologist Sun suggested that women should drink more water, urinate less, wash vulva frequently and change underwear frequently.
There are three indicators to judge urine health.
Yong Yang, an expert in urology, said that there are three indicators to judge whether a person urinates healthily, that is, whether urination is effortless, whether urine can be held back, and whether urine is yellowish and transparent. Once one of the following symptoms appears for a long time, you should pay attention to health problems.
Frequent urination and polyuria. If you urinate more than 8 times without drinking too much water, it is called frequent urination. Yong Yang, an expert in urology, said, "The increase of urination times and the decrease of urine volume each time may be due to the decrease of bladder urine storage function. If the number of urination increases, but the amount of urine does not decrease every time, it is polyuria, which may be a problem with the body's metabolic function, such as diabetes. " If frequent urination is accompanied by discomfort such as urgency and dysuria, we should be alert to whether there is urinary system infection.
Long urination time and poor continuity. Middle-aged and elderly men have symptoms such as prolonged urination, poor continuity, dripping sensation, dysuria, dysuria and nocturia, which are all signs of prostate disease.
Urine is frothy and smelly. When urinating, if the foam in the toilet is found to increase, especially when the foam is obvious for the first time in the morning, it may be caused by kidney disease. Go to the hospital for routine urine examination in time to see if protein in urine increases. If the urine smells of rotten apples, it is suspected to be a sign of diabetes.
Abnormal urine color
Red: It means that there may be too many red blood cells in urine, also called "hematuria", which is mostly caused by kidney diseases, stones, prostatitis and bladder tumors. If severe low back pain accompanied by hematuria occurs, it is mostly caused by stones, such as kidney calculi's and ureteral stones.
Soy sauce color: It is caused by the destruction of red blood cells in urine, or acute nephritis, acute icteric hepatitis and hemolytic jaundice.
White: resembling milk, sometimes mixed with white blood clots or blood, indicating chyle in urine, which is caused by filariasis or renal and lymphatic obstruction.
Urinary yellow: Berberine, vitamin B and other drugs can cause urinary yellow. But if you don't take medicine, and the urine yellow lasts for more than half a month, you should be vigilant. Too yellow urine often indicates hepatobiliary diseases, such as hepatitis, gallstones, biliary obstruction, obstructive jaundice and other diseases.
