Why do I keep waking up during the night to urinate? Is it due to aging or illness?

Lately, I've been waking up once or twice in the morning because I need to urinate. I used to sleep soundly until morning, but now I have to go to the bathroom in the middle of the night. The problem is that I have trouble falling back to sleep and feel extremely tired in the morning. I don't drink a lot of water, so why am I experiencing this? Could it be a sign of a sensitive bladder, my age, or another health issue? Has anyone else experienced this symptom during this time of year? I'd like some advice on how I can manage it and sleep soundly without waking up in the middle of the night.
