Sandra Lee, known as Dr. Pimple Popper, had a stroke while filming her Lifetime show. She initially felt unwell and didn't go to the hospital immediately, but sought medical attention the next day. An MRI revealed an ischemic stroke, which occurs when blood vessels in the brain are blocked, depriving cells of critical oxygen and nutrients. Dr. Lee stopped filming for two months while she recovered, reflecting on her lifestyle issues. She believes the stroke is a blessing in disguise, as it reminds you to take better care of yourself.
