Generally, normal people urinate 0-1 times at night, if they urinate more than twice, it is called frequent urination and increased nocturia. Whether it is normal to get up to urinate 3 times at night should be analyzed in specific problems. If you drink more water at night, drink more tea or beer, have cold weather or take antihypertensive drugs containing diuretic ingredients, it is normal to urinate more often at night without other obvious discomfort symptoms. Otherwise, an increase in the number of urination at night often indicates symptoms of lower urinary tract obstruction. It is common in young and middle-aged men with prostatitis and in older men with prostate enlargement. In female patients it may be caused by an elevated posterior bladder neck lip and bladder neck obstruction, often requiring cystoscopy. In addition to frequent urination, it is often accompanied by waiting to urinate, incomplete urination, and difficulty in urination.
