In men, an enlarged prostate (benign prostatic hyperplasia) can press on the urethra, making it difficult to completely empty the bladder and causing frequent urination, especially at night. In women, hormonal changes during pregnancy or menopause can alter urinary function.
Drinking large amounts of water is not always the primary cause; while staying hydrated is important, excessive urination without an apparent cause may be a reason to consult a doctor.
How many times should you pee a day?

Most people pee on average about seven to eight times per day. If you feel the need to pee more than that, or if you have to get up to pee every 30 minutes to an hour, you might be frequently urinating. But context matters. This may still be “normal” if you’re drinking lots of fluids or taking certain medications. What matters most is what’s typical for you.
