What is the difference between fainting and passing out?
Faint, black out, swoon, pass out. They’re all names for the same thing—a temporary loss of consciousness followed by a fairly rapid and complete recovery. Fainting occurs when something interrupts blood flow to the brain.
Do you stop breathing when you faint?

Why do I faint when I poop?
But straining lowers the volume of blood returning to the heart, which decreases the amount of blood leaving it. 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.
What triggers syncope?
Syncope is a symptom that can be due to several causes, ranging from benign to life-threatening conditions. Many non life-threatening factors, such as overheating, dehydration, heavy sweating, exhaustion or the pooling of blood in the legs due to sudden changes in body position, can trigger syncope.
Is it normal to be sick after fainting?

Can lack of vitamin D cause fainting?
Correlation analysis showed that syncope was associated with low vitamin D (r = −264, P = . 003) and vitamin B12 levels (r = −233, P = . 009) (Table 2). However, in multivariate regression analyses showed that only low vitamin D levels increased risk of syncope [OR: 0.946, 95% (0.901‐0.994)].
