@Mykol-- I think as we get older, it is common to not have quite as much control over your bladder. Just because you have to get up during the night to use the restroom doesn't necessarily mean your bladder is overactive.
For me, my first symptoms happened during the day, when I wondered if I was going to make it to the bathroom quick enough. When this started happening several times a day, I never wanted to be far from the bathroom.
It eventually got to the point where this was also waking me up at night, and that is when I finally decided to get it checked out. I had a cystoscopy done, which is not a fun test, but showed that I was not completely emptying by bladder.
There are several different ways they can treat this, and it never hurts to ask your doctor about it.
