'Get up at night' or 'Don't get up at night', which is healthier? Urologists have the answer!
Many elderly people, due to kidney deficiency or urinary system disorders, often get up at night to go to the toilet frequently. Normal adults should urinate about 0 to 2 times at night. If the frequency exceeds three times or more, It is necessary to pay attention to it, most of which are problems with the kidneys or urinary tract.
What does normal urine look like?
【Urine volume】
Under normal circumstances, an adult's daily urine output is roughly 1000 to 2000 ml, with an average of 1500 ml.
Polyuria is defined as more than 2500 ml of urine in 24 hours.
Less than 400 ml of urine within 24 hours and less than 17 ml per hour is oliguria.
Anuria is defined as less than 100 ml of urine within 24 hours.
Diabetes insipidus is defined as urine output of more than 5 liters in 24 hours.
【Number of urination】
Under normal circumstances, adults urinate more than 8 times a day, and no more than twice at night.
The frequency of urination is affected by many factors, such as: water intake, exercise, perspiration, surrounding environment, personal emotions, dietary reasons, genetic factors, sleep status, etc. will affect the frequency of urination.
【Urine color】
The normal color of urine is light yellow, and sometimes the urine will appear amber. No matter what color it is, it is relatively clear and transparent, without sediment or floc, and there is no abnormal smell when urinating.
After getting up in the morning, the color of the urine will turn yellow due to the reason of not urinating for a long time, and there is a distinct smell of urine.
【Urine Specific Gravity】
Urine specific gravity refers to the weight ratio of the same volume of urine to pure water at 4°C.
Urine specific gravity is affected by renal tubular reabsorption and concentration functions, and is proportional to the number and quality of soluble substances in urine, and inversely proportional to urine volume. Adult urine specific gravity is generally 1.015-1.025, and morning urine is the highest.
How often is it normal to get up at night?
According to medical research, the normal repair and filtering functions of the kidneys are carried out in deep sleep, so that the damaged cells in the kidneys can be repaired, so as to maintain the normal excretion function of the body.
Under normal circumstances, the number of enterprises is judged according to their own conditions and the amount of drinking water before tax. The body tissues and cells lose about 2500 ml of water in a day, so it is normal to excrete 1 or 2 times every night.
【Get up at night】
1. Drink a lot of water
Water is the source of life, and everything in the world is inseparable from the nourishment of water. Drinking more water can increase the basal metabolic rate, accelerate the blood flow of the whole body, and reduce the deposition of toxins and garbage.
If you drink too much water at night, it will also increase the frequency of urination at night, causing you to wake up frequently.
2. Small bladder capacity
The bladder is an important organ for storing urine. When the kidneys filter water and other substances into urine, it will flow into the bladder. When the bladder is full, it can send a signal to the brain to urinate and promote the excretion of urine from the body.
Under normal circumstances, the bladder capacity of the human body is 300~500 ml. Some people may have a small bladder capacity. Due to the limited storage space, a little urine is produced, and there will be a feeling of wanting to urinate, increasing the number of urination at night.
If it is caused by physiological reasons, the bladder capacity is small, and whether it is caused by bladder space-occupying lesions, enlarged uterine compression during pregnancy, tuberculous bladder contracture or large bladder stones, etc., if it is caused by pathological reasons, nighttime If you urinate frequently, seek medical attention immediately.
3. High mental stress
People who are highly stressed or depressed for a long time will experience frequent urination, urgency, and dysuria due to their bad mood, and increase the number of urination at night.
4. Disease impact
People with chronic diseases such as high blood pressure and diabetes may experience increased frequency of urination at night due to aggravated kidney atrophy.
Frequent urination at night does not mean that there is a problem with the kidneys, it is likely to be a disease of other organs.
5. Inflammatory stimulation
When there is inflammation in the bladder, the neurosensory threshold is lowered, and the urination center is in an excited state, resulting in frequent urination and decreased urine output. Therefore, frequent urination is an important symptom of cystitis, especially acute cystitis and tuberculous cystitis.
【Do not stay up at night】
For most people, they do not have the habit of urinating at night. Unless they go to bed too late or drink too much water before going to bed, they will increase the number of urination at night.
Many people think that staying up late at night is a sign of kidney health. In the kidney, the glomerulus plays a filtering role, while the renal tubule can help with absorption. With age, these two parts of the kidney also age. , the concentration of urine is also reduced.
The reason why many people stay up late at night may be because of psychological troubles or because it is too difficult to get up.
The doctor said: holding back urine is a very unhealthy behavior. Holding back urine for a long time cannot discharge urine in time, which will increase the burden and pressure on the kidneys, and also induce inflammation of the urinary tract. For the sake of health, urine must be discharged in time.
