”I keep getting up at night, what do you think is happening to me?” . In outpatient and ward work, we often encounter such questions from elderly patients. Thinking about elderly people, their energy is not as good as young people, and sleep is supposed to restore their energy. However, the urination every 1 or 2 hours makes them anxious and sleep is difficult to guarantee, so they urinate more frequently. Over time the control of the cause disease will also be affected. Therefore, how to properly find the causes of increased nocturia and how to properly cope with it is a problem that most elderly people want to solve. First, it is necessary to clarify what increased nocturia is. Nocturia is an abnormal increase in the volume or frequency of urination at night. In general, a healthy person urinates about 1.6 liters every 24 hours, and the ratio of the number of times a normal person urinates day to night is about 3 to 4:1 for teenagers, 1:1 for middle-aged and elderly people, and 1:3 for elderly people over 70 years old. if the amount of night urine is greater than 1/2 of the total amount of urine in a day or if the ratio of the number of times a person urinates day to night is reduced, it is nocturia. For diabetic patients, the main causes of increased nocturia are: 1) hypertonic diuresis caused by hyperglycemia; 2) renal tubular injury; 3) male prostatic hyperplasia; 4) female pelvic floor muscle relaxation; 5) urinary tract infection; 6) neurogenic bladder. The above causes have different manifestations: for example, in addition to increased nocturia, most of them are accompanied by increased symptoms of dry mouth and excessive drinking, as well as itchy skin and weight loss; renal tubular injury can be accompanied by increased blood pressure; prostatic hyperplasia can be accompanied by difficulty urinating, waiting for urine and dripping urine in addition to increased nocturia; in the case of pelvic floor muscle relaxation, most women have a history of multiple fertility or heavy physical labor, and increased nocturia can be accompanied by Most women have a history of multiple fertility or heavy physical labor, and increased nocturia can be accompanied by uterine prolapse, and coughing and other actions that increase abdominal pressure can cause overflow; urinary tract infections can have urinary frequency, urgency, painful urination, and in severe cases, chills and fever; neurogenic bladder can have a sense of incomplete urination. Therefore, when diabetic patients present with increased nocturia, the first thing to clarify is whether there is poor glycemic control. If it is ruled out, further clarification is needed to determine whether there are several possibilities mentioned above. A simple self-inquiry can be made to roughly determine the possible causes, and a specialist visit to the hospital can be made to clarify the cause and adopt a reasonable treatment method. In daily life, some small changes can also reduce the problem of increased nocturia to a certain extent. For example: reduce drinking tea or coffee or drinking too much water before bedtime; take diuretics at once in the morning rather than in the afternoon or evening; take medications for constipation before bedtime so that patients can keep having a bowel movement in the morning; avoid intravenous infusions in the afternoon or before bedtime; develop the habit of urinating twice or even several times; increase pelvic floor muscle exercise; and pay attention to personal hygiene to reduce the occurrence of infections. In addition, appropriate use of Valium or Chinese medicine to improve the quality of sleep can also reduce the old habit of getting up at night to a certain extent. In short, if you are also troubled by “sleepless nights”, please look for the possible causes as soon as possible. Intervene earlier and get more sleep!
