　　Expert analysis: healthy The ideal urination standard is: 8 times a day, about 300 ml each time, and the total volume does not exceed 3000 ml. If it is not caused by drinking water more than 8 times, it is called frequent urination. Many people think that they always have to urinate. Kidney deficiency . In fact, most frequent urination has nothing to do with the kidneys.

　　Frequent urination but low urine output may be a problem with the bladder and urethra； Not only are the frequency frequent, but the urine output is also large, it may be an internal metabolic disorder. disease , such as diabetes or polyuria. Only if you urinate frequently and have high proteinuria during a routine urine test, you may have a kidney problem.

　　Some people urinate frequently because they always feel the urge to pee. At this time, you can check yourself: if you have an urgent need to urinate, it may be an overactive bladder. ； I have a vague urge to urinate, not too urgent, maybe it’s the feeling nerve Chronic inflammation of the bladder caused by allergies, or urinary tract infections.

　　A. 0 times； B. 1 time ； C. 2 times ； D. 3 times

　　Correct answer: B

　　Expert analysis: Urinating 8 times a day, 7 times during the day and 1 time at night is the optimal ratio.

　　Waking up too much at night may be caused by drinking too much water before going to bed. This is normal, and there is no need to deliberately reduce the amount of water you drink at night to stay up late, unless you are a patient with congestive heart failure or hypertension, who needs to control their water intake throughout the day. Don’t worry about drinking too much water at night and wake up in the morning Eye The face will become swollen. Only people with kidney problems will do this. Healthy kidneys will metabolize normally and will not cause edema.

　　In order to reduce the risk of getting up late at night, many elderly people dare not drink any water at night. Over time, this will make their urine very concentrated, leading to bladder stones and other diseases.

　　Another situation is that you don’t drink much water at night and you always wake up at night. This is the same as frequent urination during the day. A large amount of urine each time indicates a medical metabolic disease.； A small amount of urine each time indicates a problem with the bladder and urethra.

　　Expert analysis: Generally speaking, it takes 30-45 minutes for water to metabolize normally in the body, which is equivalent to the time of a class in school. However, even if you choose other options in this question, it does not necessarily mean that there is something wrong with your body, especially your kidneys. The length of time water stays in the body is mainly affected by two factors. One is whether the food is salty or light. When you eat too much salt, it will take longer to urinate because salt causes water to be retained in the body.

　　The second is whether you eat more or less. Before the party, I drank beer without eating anything, and soon I wanted to go to the toilet. ； And after eating something, especially a staple food, and then drinking alcohol, it is less likely to have the urge to urinate. The reason is simple: food absorbs water like a sponge, prolonging the time it takes for it to be excreted.

　　In addition, whether the body is dehydrated and whether the weather is hot or cold will also affect the time of urination. After exercising, you will sweat all over and your body will be highly dehydrated. All the water you drink will be absorbed and will not be easily excreted. ； When the weather is too cold, it is difficult for water to evaporate through sweat and can only be turned into urine, which makes people want to go to the toilet all the time.
