Organ transplants are medical miracles that save thousands of lives every year. However, the journey\u00a0doesn’t\u00a0end once the surgery is complete. The biggest hurdle patients face post-surgery is the body’s natural defense system.\u00a0Understanding\u00a0<\/span>what causes graft rejection response\u00a0is essential for anyone undergoing a transplant procedure.\u00a0It is a biological battle where your immune system mistakes the life-saving new organ for a dangerous invader.\u00a0<\/p>\n

This guide explores the mechanisms behind rejection, the specific\u00a0graft rejection types\u00a0you should know, and the proven\u00a0strategies to prevent graft rejection\u00a0to ensure long-term health.\u00a0<\/span>At\u00a0<\/span><\/i><\/b>Doral Health & Wellness<\/span><\/i><\/b><\/a>, we have all the answers you need.<\/span><\/i><\/b>\u00a0

Understanding What Causes Graft Rejection Response<\/span><\/b>\u00a0<\/span><\/p>\n

At its core, graft rejection is a case of mistaken identity. Your immune system is designed to protect you from foreign threats like bacteria, viruses, and toxins. It does this by recognizing specific proteins called antigens on the surface of cells.<\/span>\u00a0<\/span><\/p>\n

When you receive a transplant, the new organ or tissue comes with antigens that are different from your own. Your immune system spots these “foreign” markers and launches an attack to destroy them. This aggressive defense mechanism is\u00a0<\/span>what causes graft rejection. The severity of this response depends on how closely the donor’s antigens match your own, known as HLA (human leukocyte antigen) matching.<\/span>\u00a0<\/span><\/p>\n

Major Graft Rejection Types<\/span><\/b>\u00a0<\/span><\/p>\n

Rejection\u00a0isn’t\u00a0a one-size-fits-all event. It can happen minutes after surgery or years down the line. Medical professionals categorize\u00a0<\/span>graft rejection types\u00a0into three main stages:<\/span>\u00a0<\/span><\/p>\n
