One of the first negative things I learned about this type of surgery is that you lose some of your hair. I was told that this happens a lot less with gastric sleeve patients. That was in fact part of the reason why I chose this type or surgery. I have very thin hair as is and am pretty sad to see this much hair loss on an almost daily basis. Am I going to go bald?!?! Does rogein work for women? It is too hot to wear wigs!!
