Why does my urine leak when I cough?

Coughing, sneezing, laughing, or lifting increases pressure inside the abdomen. The muscles and tissues supporting the bladder and urethra may not close firmly enough during that brief increase. This is called stress urinary incontinence. Pregnancy, childbirth, menopause, pelvic surgery, constipation, long-term coughing, and changes in pelvic-floor strength can contribute. The leakage may be a few drops or a larger amount; its size does not identify the cause. A cough itself can have many explanations, including asthma, allergic rhinitis, reflux, or a respiratory infection, and treating a persistent cough may reduce repeated leaks.

Notice when leakage occurs, how much there is, and whether urgency, burning, or blood is present. Avoid repeatedly going to the toilet just in case, but empty your bladder before activities that reliably trigger symptoms. Pelvic-floor exercises, taught correctly and practised regularly, may improve control; a clinician or pelvic-health physiotherapist can check your technique. Keep constipation managed, and seek advice about a cough that persists. Do not stop prescribed medicines without medical guidance, even if you suspect one affects urination.

Arrange a medical assessment if leakage is new, recurring, troublesome, or affecting exercise, sleep, work, or intimacy. Seek prompt care for blood in the urine, painful urination, fever, new back or side pain, inability to pass urine, or sudden leg weakness or numbness. A clinician may ask about your bladder habits, examine the pelvic floor when appropriate, and test a urine sample to look for infection.

Ask whether your symptoms fit stress urinary incontinence, whether pelvic-floor physiotherapy is suitable, and whether your cough or medicines could be contributing. Mention pregnancy or childbirth history, pelvic procedures, constipation, urgency, and any burning or blood.
