my brain has been very foggy 2 weeks out from fainting

Some people are incontinent during a profound faint. If you stay sitting up, your brain will remain starved of oxygen for longer, and during your faint you might even have jerky movements, that can be misinterpreted as a fit. If you faint to the floor, or lie down before fainting (and if possible raise your legs), blood immediately returns to your heart, which can then pump blood to your brain again, and you regain consciousness. (Syncope, pronounced sin-co-pee, is the greek / medical term for a blackout caused by not enough blood reaching the brain).

The result of this faulty response is that the heart cannot pump enough blood to the brain, and the lack of oxygen reaching the brain then makes you pass out. So when you begin to feel sweaty and faint this is because instead of constricting, some blood vessels get even wider (“vaso-dilate”), and the heart instead of speeding up may slow down or even stop momentarily. In some people, these attempts to maintain the blood pressure are ineffective in the specific situations when the fainting reaction occurs Usually the body counteracts this and tries to maintain the blood pressure, by constricting the blood vessels in the legs and abdomen, and by making the heart beat faster. With more blood held in your legs, less blood returns to the heart, and the amount of blood the heart can pump around the body diminishes, and the blood pressure in the circulation will begin to drop. When you are upright, standing or sitting still, blood drops under the influence of gravity down into your legs.
