hernia before sugery

Ok i went to my family doc last week for my "weigh in" and also because of this "lump/bump" on my uper right side and he said it is a hernia, and was going to schedule me with a surgeon but didn't because of me going through wls he is hoping that i can get my wls soon and i can get both things taken care of. My questions are these though... why did i get a hernia before? will that make me more prone to getting hernias after surgery? what can i do to help with the hernia? does andyone think a hernia should be opperated on before my wls??? or is it ok to wait till surgery? The way my family doc said "oh you'll have wls soon enough so this can get solved" realy didn't give me a time line or if one is needed.. any information would be great. God bless you all Paula
