Internal Medicine

Slow urine flow, also known as urinary hesitancy or a weak urine stream, is often a sign of an underlying issue affecting the bladder, urethra, or surrounding structures. Common causes include an enlarged prostate (BPH), urinary tract infections, bladder muscle weakness, nerve damage, urethral strictures, and side effects from certain medications such as antihistamines, decongestants, or antidepressants.

Because slow urine flow can point to many different conditions—some minor, others requiring prompt treatment—it's important to identify the likely cause early. Taking a free, instant, online symptom check can help you understand what may be behind your symptoms and guide you on the best next steps, whether that's self-care, seeing a primary care provider, or consulting a urologist.
