Frequent Urination: Common Causes, Tests, and When to Worry#
Frequent urination is often due to high fluid intake, urinary irritation, infection, or uncontrolled blood sugar. If it is new, persistent, or disturbing sleep, it should be evaluated instead of ignored. In adults, one key rule-out is diabetes.
Quick answer#
Most cases are not emergencies, but frequent urination with thirst, fatigue, fever, pain, or weight loss needs medical review. Early testing can identify treatable causes quickly.
