“How long is recovery after a heart transplant?”

30days

Up to 12 months

I hate to reply this way, but, "It depends."  (I'll assume your friend is a female, the same questions would apply to a male recovering from a heart transplant.)    How old is your friend?    What was the condition that caused her to need a heart transplant?    What types of other medical problems does she have?    What kind physical shape is she in?    How long has she been in the hospital prior to her heart transplant?    What other organ damage does she have as a result of her heart condition?    Is she a diabetic? Smoker?  Overweight?    How motivated is she to recover, and what other disabilities does she have that may impair her recovery? I know you wanted an answer with a given number of days or weeks.  But there are so many confounding issues involved.        All the Best to you and your friend.
