Micturition syncope or post-micturition syncope is the name given to the human phenomenon of fainting shortly after or during urination. It is a type of vasovagal response.

People often become pale, nauseated, sweaty and weak before they lose consciousness. Sometimes even defecating, coughing, or severe vomiting may cause fainting in a similar way.

Epidemiology

Responsible for 2.4 to 8.4 percent of all cases of fainting in adults, it most commonly occurs in males. The events often occur at night or after awaking.

Causes

When one strains to increase the flow of urine, it stimulates the vagus nerve (usually more pronounced in elderly men with large prostates). The vagus nerve stimulus causes slowing down of the heart (bradycardia) and a drop in blood pressure. The heart cannot perform effectively as a pump because insufficient blood comes to it. It is classically associated with a very rare tumor known as a paraprostatic pheochromocytoma within the urinary bladder.

Treatment

There is no specific treatment for micturition syncope. General advice to men with micturition syncope includes:

• to sit while urinating
• to sit on the edge of the bed for a while before getting up and going to the toilet
• to avoid urinating while sleepy
• to urinate before sleep
