How likely is it for someone to get a heart transplant?she is 26 years old and otherwise healthy other than diabetes.

In this pt, unlikely: Since you say she is healthy, her diabetes must not be severe. 26 is very young for heart disease, unless she has done serious drugs, smokes/drinks heavily, is obese.Dm pts. Get kidney transplants > heart trnsplnts, & not if no probs!she is young and if "healthy", can actually reverse her diabetes with the proper lifestyle changes:proper nutrition is key, but also exercise&appropriate supplements.

Likely, however...: Given the chronic shortage of organs, transplant candidates have to be sorted out very carefully. For a 26 year old many efforts would be made to find a match. It would be up to a heart failure cardiologist to do a full evaluation and determine her eligibility.
