Medical help

I'm writing this to help our sister,mother,aunt! Peggy needs an operation to remove a part of her bowl. She has diverticulitis, and it flares up every other week! When this happens she is in  alot of pain, if she doesn't  get this operation she will end up with a colostomy bag! Unfortunately she needs a $1,000.00 up front co-pay  Before thay will do the operation. If anyone can help it would be very much appreciated !
