Frequent Nighttime Urination and One of Its Hidden Causes: Anti-Diuretic Hormone

Frequent nighttime urination is very common over 50

Studies have shown that for both men and women 50 years and older, the average number for nighttime urination is three times and this number tends to increase as people get older.

At the recent American Urology Association Annual Meeting in Washington DC, Dr. Jeffrey R. Weiss, MD, Professor and Chair at the Department of Urology SUNY Downstate College of Medicine, Brooklyn, NY, reported that one of the key reasons for an increase in the episodes of nighttime urination is that the kidney produces more urine at night as people grow older. This is caused by decreased levels of Anti-Diuretic Hormone – ADH.

Anti-Diuretic Hormone (ADH)

ADH is a powerful hormone that regulates water metabolism in the body. It has direct impact on the amount of the urine the kidney produces. The lower the ADH levels, the more urine will be produced.

In people 60 and older, the nighttime ADH level becomes barely detectable. For them, the urine volume produced at night (average 8 hours) is about 34% of the total volume for the entire day. The more urine produced, the more often you need to void.

As a comparison, younger people’s ADH level increases at night. The urine volume produced at nighttime in people younger than 25 years old is only about 14% of the total volume for the entire day. This means for young people, urine production is drastically reduced at night. That’s why their bladders can easily hold urine for the whole night.

The older one gets, the less the ADH, the more urine production at night and so the frequency of urination increases which results in nocturia, or frequent urination at night.

Frequent urination at night can be helped

Even age related frequent urination at night can be helped. BetterMAN and BetterWOMAN are all natural, herbal supplements that strengthen bladder muscles which in turn reduces frequent urination at night (and during the day.) There are no known side effects and they have helped thousands of men and women with bladder control issues since 1999.
