Always feel the urge to urinate before going to bed

Some people always feel the urge to urinate when they lie in bed at night, but the amount of urine is not much, and they feel the urge to urinate again not long after lying in bed after urinating. However, my urination is normal during the day, and I don't have any frequent or urgent urination. The only thing is that I always have to go to the toilet several times before going to bed. So, is this problem that occurs every day before going to bed caused by some problem with the kidneys?

1. Reasons for frequent urination before going to bed

Frequent insomnia, indigestion, or severe neurasthenia, and frequent urination before going to bed are more common in middle-aged women. Frequent urination caused by mental factors usually manifests itself as more or less urine at times, with obvious "signs" of mental effects. Especially for some long-term and severe frequent urination, relevant examinations should be carried out carefully, and it should not be easily diagnosed as frequent urination caused by psychoneurological factors.

2. The harm of psychogenic frequent urination

Frequent urination caused by mental stress will not cause serious consequences to your health. For those whose frequent urination affects their study, work, and rest, psychological therapy and nerve-regulating drug treatment can be performed.

3. Causes of frequent urination

1. Bladder factors. The bladder is an organ that stores urine. Under normal circumstances, the bladder can store a certain amount of urine (usually 300 ml). When the amount of urine gradually increases and a certain pressure is formed in the bladder, the bladder will send a message and people will feel the urge to urinate. However, when the effective volume of the bladder is reduced due to disease, the amount of urine stored naturally decreases, and it is easy to feel the urge to urinate in a short period of time. For example, there is a tumor, stone, foreign body, ectopic endometrium in the bladder, or the organs near the bladder are enlarged, such as ovarian tumor or cyst, pregnancy or uterine fibroids. Excessive obesity and other conditions that put external pressure on the bladder will affect the effective volume of the bladder and cause frequent urination. Even a small amount of urine will produce a strong urge to urinate.

2. Infectious factors . Due to the physiological characteristics of women, the total length of the urethra is much shorter than that of men, creating opportunities for ascending infections such as bacteria, viruses, and pathogens. Once pathogenic microorganisms infect the body, if the amount is large or the patient's disease resistance is poor, their reproduction rate will accelerate, causing certain effects on the bladder. The stimulation of inflammation often causes the urge to urinate even when there is very little urination. This frequent urge to urinate can dilute the bacteria and "drive out" the bladder through frequent urination. Frequent urination caused by inflammation is accompanied by a special feeling of urgency and pain when urinating. The key to infection by pathogenic microorganisms is early and effective treatment.

3. Mental factors. People always have a feeling that when they are about to get on a train, board a plane, or depart, they habitually urinate, but many people feel the urge to urinate again soon after urinating. This is the result of mental effects. Mental stress or neuropathy related to urination can cause nervous system reflex disorders and annoying frequent urination. Psychogenic polydipsia, polyuria and neurogenic cystitis are common causes of psychoneurological factors.
