I recently had Open Heart Surgery (4/25/11) which lasted 2 days, I now have a mechanical aortic valve and have notice hair loss over the past few months. Is this common, especially since surgery lasted 2 days? I was sedated thru the night and surgery continued the following day.
Stress from a surgery can induce hair loss in predisposed people. Is the hair loss all over (telogen effluvium) or is it localized in a pattern? This is what a good doctor can tell you and then, after a proper diagnosis is in hand, treat it appropriately.
