when is low blood pressure considered dangerous?

Causes fainting: When your blood pressure is too low, you do not get enough oxygen to your brain and people feel lightheaded, dizzy or like they are going to faint. That is dangerous, but the most common cause of low blood pressure is not enough fluids or dehydration. If you are still having low blood pressure and feeling dizzy after drinking at least 64 oz per day, then you should see your doctor.
