Causes of frequent urination at night in men

There are many reasons why men often urinate at night such as side effects of drugs, sleep disorders or certain diseases.

Nocturia is the condition of waking up many times during the night to urinate. Doctor Nguyen Ngoc Tan, Department of Urology - Andrology and Nephrology, Tam Anh General Hospital, Hanoi , said that some signs of frequent nocturia in men are: urinating more than once from the time you go to bed until the next morning, feeling like you haven't finished urinating, still feeling uncomfortable in the lower abdomen, weak urine stream, smaller than normal or having to strain.

According to the American Urological Association, one in three adults over the age of 30 experience nocturia. Most people can wake up once a night to urinate, but more frequent urination can be a sign of a medical condition or a variety of other causes.

Drink plenty of fluids before bed

Men tend to consume more alcohol and caffeine than women. This is a common cause of nocturia. Dr. Tan said that many people have the habit of enjoying a cup or two of coffee in the evening instead of drinking it in the morning after eating. Caffeine causes the bladder to contract to a lower volume, making you feel more urgent and frequent need to urinate.

In addition, many people drink alcohol at night. Alcohol prevents the kidneys from reabsorbing water. When drinking alcohol, the body produces more urine and has to urinate many times at night.

Use certain medications

Some medications make you urinate more often, such as blood pressure medications, diuretics, and medications used to treat psychiatric disorders. If you urinate more often due to medication, you should ask your doctor to adjust the medication you are taking or the appropriate time to take it. You can avoid taking diuretics in the evening. They increase the amount of water and salt your body excretes in the form of urine.

Sleep disorders

Sleep apnea increases the frequency of nocturia. Therefore, to improve nocturia, it is necessary to treat sleep apnea. In addition, some neurological disorders also cause uncontrolled urination, frequent urination at night such as spinal cord compression syndrome, multiple sclerosis, Parkinson's...

Aging

As men age, the muscles in their bladder weaken. In fact, it is considered normal for a man over 50 to wake up once a night.

Dr. Tan explains that the body produces more urine at night than during the day. In some people, the fluid absorbed during the day collects in the lower limbs and when lying down, the fluid circulates back. The heart and kidneys recognize the extra fluid and need to be eliminated. To limit the condition of nocturia due to aging, men should drink less at the end of the day.

Prostate disease

An enlarged prostate irritates the nerve endings in the bladder neck and can compress the urethra, causing the bladder to contract incompletely after each urination, leading to residual urine and making the patient feel like he or she always wants to urinate. When suffering from prostate enlargement, the patient needs to talk to the doctor to have a treatment plan with medication or surgery depending on the condition.

Benign prostatic hyperplasia is a disease that affects 50% of men between the ages of 50 and 60. The prostate surrounds the urethra, so if it enlarges, it will obstruct or severely block the flow of urine. The bladder wall also thickens, making it difficult to empty, causing nocturia. Some lower urinary tract disorders that cause nocturia include overactive bladder, pathological hypersensitivity, interstitial cystitis, urinary tract infections, etc.

Dr Tan said that people need a good night's sleep to feel refreshed and rested in the morning. However, constantly waking up at night to urinate can lead to sleep deprivation and reduce the quality of life. Nocturia or nocturia is really a concern if you have to wake up more than twice a night.

Patients who have changed their lifestyle but have not improved their nocturia need to be examined and treated promptly. Frequent urination at night can lead to many underlying health conditions if not treated promptly, such as: heart diseases such as congestive heart failure; diabetes; high blood pressure, chronic cystitis, chronic kidney failure, prostate enlargement...
