Overactive Bladder Symptoms
4. Nocturia
Nocturia, also called nocturnal polyuria, describes excessive urination at night. While sleeping, the body produces a reduced amount of urine compared to in the daytime. However, this little amount is more concentrated.
This is why most people do not have to wake up to urinate at night, and can sleep for 8 hours without interruption from the bladder. You may have an overactive bladder if you have to wake up from your sleep to urinate.
