Seventy-year-olds are generally considered to be normal to urinate no more than twice at night, and more than twice can be considered to be the presence of excessive water consumption before bedtime, prostate disorders, and bladder disorders. Generally speaking, it is normal for adults to urinate no more than once at night, but due to age, there may be a decline in the contractile function of the urethra muscle, so in the clinic, it is generally considered normal for the elderly to urinate no more than twice at night. If it is more than two times, it may be due to the physiological increase of nocturia caused by the habit of drinking too much water before going to bed, prostate hyperplasia in elderly men, urinary tract infection in elderly women, as well as bladder stones, tumors, neurogenic bladder and other conditions. Therefore, no more than two is considered normal, prolonged nocturia more than two is recommended to go to the regular hospital for further examination, if abnormal, timely treatment.
