As the saying goes, "There are many children, and the elderly have more urine." When people get older, the symptoms of frequent nights are really just normal phenomena of natural aging?
This is not the case. The increase in nocturia is actually a manifestation of a physical illness.
In view of the fact that normal adults do not urinate or only have one discharge at night, the World Health Organization (WHO) has more than two or more urinations at night as a reference standard for nocturia. The International Society for Urinary Control (ICS) defines it as a patient who wants to get up and urinate for one or more times at night, and interrupts sleep each time. However, neither of them considered specific indicators such as urine volume.
At present, most of the urinary urination times ≥ 2 times, and the urine volume > 750 ml or greater than the daytime urine volume (normal day and night urine volume ratio of 20 x 1778 1) is the criterion for nocturia.
For the elderly, with the increase of age, the secretion of vasopressin (ADH) is less, the renal concentrating function is reduced, the contractile force of the bladder detrusor atrophy is reduced, the residual urine is present, the actual capacity of the bladder is reduced, and the number of urination at night is Increased, it is reported that the elderly who are over 80 years old have an increase in nocturia up to 80%.
In addition, physical and mental factors such as drinking plenty of water, mental stress, and insomnia before going to sleep may also be the cause of the increase in nocturia in the elderly.
Nocturia is not a minor problem. First, it affects the patient's sleep, leading to poor mental health during the day and reducing their quality of life. Secondly, many elderly people with nocturia are older, and urinating at night increases the risk of falls and fractures.
A cohort study of the association between nocturia and fall in the elderly in the community showed a 28% increase in the risk of falls when the number of nocturias exceeded three. Nocturnal urinary still is an independent risk factor for falls after factors such as age, gender, ethnicity, and follow-up time are assessed in assessing risk factors associated with falls.
