  • The effects of alcohol on various organs and organs of the body can cause frequent urination:

Drinking alcohol has a variety of effects on your body that cause you to lose control of your urine.


  • Let's start with the effect of alcohol on the brain:

Normally, a hormone is produced and secreted in the brain called Anti diuretic hormone, or ADH for short. This hormone sends signals to your kidneys and prevents the kidneys from producing dilute urine and high-volume urine, and this will prevent you from losing too much water, however, drinking alcohol inhibits the secretion of this ADH hormone and suppresses it, and as a result, the kidneys will produce more dilute and bulky urine than usual.

Dr. Ulchaker says:

“”If you pass out later or are sleeping too soundly, your bladder continues to fill more quickly and gets over distended. Your body then release the pressure by urinating.””


It is certain that if you drank too much alcohol or drank alcohol late and just before bedtime, The ADH will stay suppressed for longer, and the kidneys' excessive production of dilute urine will cause you to wet your bed during sleep.


  • The effects of alcohol on the bladder can cause urination during sleep:

There is an important muscle in the wall of your bladder that can empty the bladder by contracting it. This muscle is called detrusor.

Drinking alcohol will stimulate this muscle, and this is how you will experience urinary incontinence and wetting your bed after drinking too much alcohol.


  • Drinking beer and alcohol increases the production of dilute urine:

Alcoholic beverages cause a large amount of fluid to enter your body. When the body is exposed to a large volume of fluid, it increases the production and excretion of dilute urine to balance, so the volume of urine accumulated in the bladder and bladder dilation will also increase.

This is what Dr. Ulchaker says:

“Drinking alcohol causes your body to pull from its liquid reserves .which can lead to dehydration and add even more volume in your bladder.”


It should be noted that caffeinated alcoholic beverages are more likely to be associated with increased urination and urinary frequency than decaffeinated alcoholic beverages. Because caffeine itself causes frequent contraction and stimulation of the bladder wall muscle called the detrusor.

Caffeinated beverages and similar beverages

They will create special conditions for your body:

Double-whammy for your bladder
