Can you tell me if heart failure is caused by anorexia, will recovery from the eating disorder reverse the heart failure?
Yes. Heart failure can be caused by anorexia and it is reversible. It requires following the plan outlined by professionals for slowly increasing your intake of nutrition. You must be committed to helping yourself.
It doesn't. It doesn't cause lung disease but chronic pulmonary congestion due to heart failure causes shortness of breath.

Basic medicine. Lab work is far less helpful than history bland physical exam for evaluating the heart. Cold arms means basically nothing. If you are not having chest pain or syncopal attacks and can keep up physically with your peers doing physical activities, be glad for a healthy heart.
