What is a vagus nerve attack?
A vasovagal attack is a disorder that causes a rapid drop in heart rate and blood pressure, resulting in decreased blood flow to the brain and fainting. Vasovagal attack is the most common cause of fainting. The disorder is also referred to as neurocardiogenic syncope.

The vagus nerve and its branches can be damaged by diseases, such as diabetes, or by surgery to the stomach or small intestine.

Why do I faint when I poop?
Special pressure receptors in the blood vessels in the neck register the increased pressure from straining and trigger a slowing of the heart rate to decrease in blood pressure, leading people to faint.
