Graft Rejection

Graft rejection occurs when your immune system mistakenly identifies a transplanted organ or tissue as foreign and attacks it. This response is similar to how your body fights off infections. The immune system uses cells and proteins to identify what belongs to you and what doesn't. If it recognizes the graft as foreign, it can damage or destroy the new tissue. To prevent rejection, patients usually take medications that suppress their immune response. Effective management allows many transplants to function well long-term, but rejection remains a risk that needs careful monitoring and treatment.
