Internal Medicine

Delayed urination — when it takes time to start a urine stream — is often caused by medications (such as antihistamines, decongestants, or antidepressants) or underlying medical conditions affecting the urinary system, including an enlarged prostate (BPH), urinary tract infections, bladder dysfunction, or nerve-related issues.

If you're experiencing this symptom, identifying the cause early can help prevent complications like urinary retention or infection. Take a free, instant, online symptom check to better understand what may be behind your delayed urination and get clear guidance on the right next steps.

Explanation

A delay in starting a urine stream, known as urinary hesitancy, can occur for several reasons. Medications can sometimes cause this problem. Some drugs might make it hard for the bladder to squeeze out urine. This is called drug-induced urinary retention.

Medical conditions can also cause urinary hesitancy. Sometimes, the bladder muscles don't work right, or there's a blockage, making it hard to start urinating.

In young people, like teenagers, urinary retention might happen suddenly. This can be due to different reasons, like a blockage or a problem with the nerves that control the bladder.
