Uncle Wang, who is more than 60 years old in the neighborhood, nervously told Huazi that his "waist" may have a problem, and he could not sleep peacefully for a long time, and he had to get up 2 to 3 times a night when he slept. Uncle Wang said that he may be older, he used to be young and could urinate 3 meters in the wind, but now he only wants the tailwind not to get wet shoes.
Huazi asked Uncle Wang about the symptoms, and he said that the number of urinations increased, but the amount of urination was not much each time, and the urine was fine and weak, and after urination, it was also "unfinished". Huazi comforted Uncle Wang that his symptoms were not like renal insufficiency, but most likely prostate problems.
First, what is counted as an increase in nocturia
Uncle Wang told Huazi that he had seen it in his mobile phone himself, and the increase in nocturia was a kidney problem, and whether his current situation was an increase in nocturnal urine? Huazi said that the increase in nocturnal urine depends not only on the number of urinations, but also on the amount of urination.
In general, the human body mainly urinates during the day, about 4 to 6 times, 300 to 500 ml each time. At night, the reabsorption function of the human renal tubules will be maximized, and the urine will be concentrated, usually urinating 0 to 1 time to avoid frequent night urination and affect sleep.
When renal function declines, tubular reuptake is often the first symptom, manifested by decreased urinary concentration and increased nocturnal urination. If the number of urinations is more than 2 times at night, or the amount of urine exceeds 500 ml throughout the night, it means that there is an increase in nocturia.
Second, the common causes of increased nocturia
1. Increased frequency of urination:
If only the frequency of urination increases, but the amount of urine is not much each time, it is likely that it has nothing to do with the kidneys, but there is a problem with the urinary tract. For example, if there is an infection in the urinary tract, it will cause inflammation of the urethra, produce irritation, and manifest as frequent urination, urgency and tingling sensation during urination. Because the female urethra is straight and short, it is easy to be invaded by bacteria, and it is a susceptible group of urinary tract infections.
Symptoms of frequent urination in middle-aged and elderly men are common in benign prostatic hyperplasia. The male prostate gland is stimulated by androgens to continue to grow and become hypertrophied. An enlarged prostate can compress the urethra, causing difficulty urinating. Symptoms can be relieved by using drugs to control the suppression of the secretion of male hormones and relax the urethral muscles. However, if the hyperplasia is severe, surgery is required to remove part of the prostate.
Bladder diseases can also cause an increase in the frequency of urination, common diseases such as cystitis, stones, and tumors.
2. Increase in total urination:
If you have an increase in urine output and the amount of urine you urinate throughout the night exceeds 500ml, first see if you drink too much water before going to bed, or if you eat too salty dinner. Because the kidneys have a strong water and sodium regulation function, if the human body consumes too much water and sodium, it will reduce the secretion of antidiuretic hormone (ADH), resulting in an increase in urination.
Increased urine output at night is also the first symptom of decreased renal function. Long-term hypertension or diabetes, can not control the standard, it is easy to cause kidney function damage. At this time, it is normal to go to the hospital to check the urine routine, but it is possible to check the trace amount of protein in the urine, and there may be a situation of exceeding the standard.
There is also a case of increased urine output at night, that is, in patients with heart failure, because of poor circulatory function, blood stasis in the lower limbs during the daytime upright. When lying flat at night, the blood flow increases, resulting in an increase in urine output. Patients with heart failure may have edema during the day, and symptoms of chest tightness and difficulty breathing may occur after lying flat.
Diabetic patients can also develop polyuria if their blood sugar is not well controlled. And because the blood sugar exceeds the standard, it will cause a feeling of thirst, which will prompt people to drink more water and increase the amount of urine.
To sum up, increased nocturia is not necessarily a kidney problem, divided into increased frequency of urination and increased total urination, resulting in different common causes of the two conditions. If there are symptoms of increased nocturia, do not be suspicious of yourself, and go to the hospital as soon as possible for examination is the most correct choice.
