In general, a normal person usually urinates zero to once per night, and if more than twice, meaning from the time they go to bed at night until they get up the next morning, if they urinate greater than or equal to twice, they are diagnosed with nocturia. Nocturia is very common, and the prevalence increases significantly, especially with increasing age. The prevalence of nocturia is 5%-10% in young people and even up to 50% in people over 70 years old, so it is clear that nocturia affects a wide range of people. What are the dangers of nocturia? The most direct harm is that it affects sleep. Frequent nighttime urination leads to interrupted sleep, especially in the elderly, who are prone to sleep difficulties and poor sleep quality, and nocturia deepens the sleep disorder and seriously affects health. So what are the causes of nocturia? 1, physiological nocturnal urination, common in the elderly and infants and children. These people secrete more urine at night than the general population, so nocturnal urination is also more common. 2.The capacity of the bladder is reduced. The bladder is like a bottle, used to store and discharge urine. If the bottle becomes smaller and holds less urine, you will have to urinate more often. Causes of a smaller bladder capacity include bladder surgery that removes part of the bladder tissue and advanced bladder tuberculosis that causes bladder contracture. In addition, an enlarged prostate that protrudes into the bladder and takes up some of the space in the bladder or a pelvic or gynecological tumor that compresses the bladder can also make the bladder’s capacity smaller. 3, bladder urination capacity decreased. The bladder is like a bottle with a capacity of 500ml. After it is normally filled, the bottle can be emptied clean every time you urinate, and then it can be filled again and urinated again. If the bladder muscle contraction becomes poor and only 50ml can be discharged each time, then the bladder will soon be filled again, so it has to urinate frequently. 4, chronic renal insufficiency, interstitial renal tubular disease and other diseases can make the kidney’s ability to concentrate urine decrease, producing a significant increase in the volume of urine, so the number of urination will also increase accordingly. 5, elderly men with prostate enlargement, elderly women with uterine prolapse, cystitis, urethritis and other diseases can stimulate the receptors in the bladder, and even cause involuntary contraction of the bladder, which in turn produces the urge to urinate and can cause an increase in nocturia. 6.Psychological factors, such as excessive anxiety, serious sleep disorders, etc. 7. Systemic diseases that cause increased nocturia. For example, diabetes, hypertension, hyperthyroidism, chronic cardiac insufficiency, etc. How can nocturia be treated? If the exact cause of nocturia can be found and cured, nocturia can be improved. For example, if cystitis is cured, nocturia will improve significantly. In other cases, we can take some measures to reduce the symptoms. Change your habits. For example, drink less water before going to bed, reduce the intake of coffee, strong tea and other beverages. Reducing the intake of food words and eating a light diet can help improve nocturia. With the help of medications, such as desmopressin, which can reduce the amount of nocturia, and tamsulosin, which increases bladder stability. Combinations of medications can also be used if necessary, such as including alpha-blockers and/or anticholinergics plus desmopressin. Surgical treatment is possible for special cases. For example, in cases of severe prostate enlargement, the gland may be removed. Patients with small bladder capacity undergo bladder enlargement surgery, etc.
