Frequent urination is a common symptom with several possible causes. In older adults, it may be due to nocturia, a condition that increases nighttime urination. Another common cause is overactive bladder (OAB), which affects how the bladder stores and releases urine. Other potential causes include urinary tract infections, diabetes, prostate issues, or pelvic floor problems.

Because frequent urination can point to many different conditions, identifying the root cause matters. A free, instant, online symptom check can help you understand what may be behind your symptoms and guide your next steps—whether that means self-care or seeing a doctor.

Explanation

Frequent urination can be a sign of different medical conditions. In older adults, it might be due to nocturia, which means needing to urinate often at night. This can be uncomfortable and disrupt sleep. Another possible cause is an overactive bladder. This condition affects both women and men and involves the bladder not working as it should, causing a sudden need to urinate.

Possible Causes of Frequent Urination:

Nocturia: Common in older adults, this involves waking up multiple times at night to urinate.
Overactive Bladder: This condition can occur in both women and men and involves a sudden urge to urinate due to the bladder's malfunction.
