Watch Our for Migraines
A study of 27,800 women found that migraines accompanied by visual disturbances (like blind spots or flashes of light) was the number two risk factor for heart disease—second only to high blood pressure. This type of migraine may be a sign of impaired vascular function that could predispose sufferers to blood clots. If you experience these headaches, have your doctor monitor you for other heart disease red flags. And focus on lowering your overall risk by quitting smoking and exercising regularly.
