Xiao Wang works as a clerk in a company and rarely drinks water. One day, Xiao Wang was chatting with a colleague, and the colleague suddenly asked him: “I rarely see you go to the pantry to fill up water, aren’t you thirsty?” Xiao Wang reluctantly replied: “I have a bad problem, that is, If you drink a little water, you need to go to the toilet often. I didn’t care much at first, but then the situation became more and more serious, and now I can only drink less water.”

Colleagues feel very I don’t understand, he drinks a lot of water every day, but he doesn’t often go to the toilet, “Xiao Wang is young, so he doesn’t have kidney problems, right?”

1. How many times a day is it normal to urinate?

Under normal circumstances, it takes an average of 30 to 40 minutes for water that people drink to turn into urine The shortest time is 6 to 8 minutes, and the longest time is about 120 minutes, and the speed of urine formation varies from person to person.

In addition, the daily urination volume of a normal person is about 1500ml, but depending on the situation, the urination volume between 400ml and 3000ml is normal. The optimal urination frequency of human body is 5~8 times/day, including 4~7 times during the day and 0~1 times at night. If you drink very little water and urinate more than 8 times, it is a phenomenon of frequent urination.

Second, polyuria or oliguria, which is bad for the kidneys?

Normally, if your daily urination and urination fall within the “normal range” above, you should not be overly concerned. But if you urinate more than 8 times, you may have frequent urination symptoms, which are related to a variety of conditions.

Urinary frequency is related to nerve and muscle diseases of the bladder, as well as bladder capacity, drinking habits, urination habits, blood sugar levels, cold stimulation and other factors. If the bladder nerves and muscles are diseased, or the volume is small, a small amount of urine can stimulate the bladder to contract, resulting in a strong urge to urinate.

In addition, when people are in a tense and excited emotional state, the blood circulation of the body will be accelerated, the hormone levels in the body will be changed, the antidiuretic hormone will be reduced, and the bladder will also be contracted, reducing the blood pressure. Urine storage capacity.

Those who usually urinate less may be due to their naturally large bladder and urine storage capacity Big. In addition, it is also related to factors such as frequent exercise, extreme lack of water, urination habit, and disease.

People who exercise regularly have a faster rate of water consumption, even if they drink more water, they will be quickly metabolized. When the body is extremely dehydrated, the added water is reabsorbed by the renal tubules, resulting in less urine. Constantly holding back your urine will reduce the sensitivity of the bladder, and it will take a long time to urinate even if you drink a lot of water. In addition, diseases such as abnormal heart function, decreased kidney function, and blockage of the urinary tract can also lead to decreased urine output.

In clinical practice, if there is still little or no urine after drinking a lot of water, you should be more vigilant, which may be related to kidney disease.

III. Urine color-responsive disease

1. Red urine, pink

Red or pink urine may be related to diet, such as eating dragon fruit, beets, violets, etc. In addition, it may be associated with renal hematuria, hemoglobinuria, myoglobinuria, adjacent organ bleeding, porphyrinuria, etc.

2, dark brown, soy sauce-like color

acute nephritis, acute jaundice hepatitis Such diseases can cause strong tea or soy sauce-colored urine; extensive burns, strenuous exercise, and taking drugs such as nitrofurantoin and rhubarb can also cause strong tea or soy sauce-colored urine.

3, black urine

Patients with acute intravascular hemolysis such as falciparum malaria most often have black urine, and patients with melanoma tumors may also have black urine.

4. Milky white

A diet high in protein and fat can easily lead to milky urine However, if it is also accompanied by symptoms such as abnormal urination, fever, and lumbar pain, you should be alert to serious urinary tract infections such as pyelonephritis, cystitis, urethritis, and renal tuberculosis.

If the urine color is abnormal due to diet, it is generally temporary. If the abnormal phenomenon persists, it is recommended to consult a doctor.

Fourth, frequent nocturia, beware of 4 diseases

Urinate normally during the day, but the frequency of urination at night increases, more than 2 times, it belongs to “frequent urination at night” many”. Frequent nocturia needs to be alert to the following 4 diseases:

prostate problems

prostate hyperplasia is easy Obstruction of the bladder outlet, resulting in decreased effective bladder capacity, reduced bladder stability, and increased nocturia.

pelvic floor muscle relaxation, urinary tract infection

pelvic floor muscle relaxation, urinary tract Nocturia caused by infection most commonly occurs in women. When the bladder and urethra are stimulated by bacterial infection, symptoms such as frequent urination, urgency, and dysuria will occur. After the pelvic floor muscles relax, women’s ability to hold urine decreases, which can also lead to frequent urination.

Diabetes

Diabetes can easily lead to dry mouth, which can lead to excessive drinking Frequent urination and nocturia.

diabetes insipidus

secretion of antidiuretic hormone Diabetes insipidus can be caused by urination, release and abnormal operation, so that patients can not control the excretion of urine independently and go to the toilet frequently.

The middle-aged people urinate more at night, which may be diabetes mellitus Kidney disease, hypertensive nephropathy, chronic nephritis, renal failure and other diseases are signs of disease, it is best to go to the hospital for urine and kidney examinations in time.
