Diuretics are medicines that help reduce fluid buildup in the body. They help the kidneys remove salt and water through the urine. This reduces the amount of fluid flowing through your veins and arteries, which in turn, lowers your blood pressure.
Alcohol is a diuretic, which means that it increases urination. This can be an issue for men with an enlarged prostate suffering from lower urinary tract symptoms (LUTS). It could cause more frequent urination, or even a weak urine stream.
We know that when we consume alcohol, it affects our muscles – we feel sluggish, like our arms and legs cannot move properly. This extends to our bladder muscles, too.
In order to store urine, the muscles in the bladder must relax, and in order to release urine, they must contract. However, the presence of alcohol makes it difficult for the muscles in the bladder to relax, thus worsening urinary symptoms, such as frequent urination.
