If you faint it may mean you are having heart problems, stroke problems, need a defibrillator, pacemaker, or have cardiac vascular disease. Have you had your blood pressure checked, had an EKG, stress test, etc.
Maybe you have low blood sugar. That happened to a lady recently. Preventative check ups are important.
Our body is like a well oiled machine. Everything must be in check or it just doesn’t work well. Have you had your engine checked out by your doctor lately?
