In 2021, over 116,000 people were on the organ transplant waiting list in the US alone, highlighting a dire shortage. This profound imbalance in supply and demand is widely considered to be **what is the biggest problem with organ transplants?**, overshadowing many other medical and logistical challenges.

Approximately 12.5–16.5% of kidney transplant recipients in the United States have required a second transplant due to graft failure, underscoring the critical need for diligent post-operative monitoring. So, **how do you assess graft function** effectively and proactively following an organ transplant?

According to a 2017 study, the five-year survival rate for certain multivisceral transplants was 50%, highlighting the gravity and complexity of this life-saving procedure. But **what is a multivisceral transplant?** and who needs this extensive surgery? This guide provides a comprehensive overview of this advanced medical procedure for those facing irreversible abdominal organ failure.

Medical advancements have dramatically improved post-transplant survival rates, transforming organ transplantation from an experimental procedure into a life-extending reality for thousands. Understanding how long can a person live with a transplanted organ involves considering many variables, from the type of organ to the patient's overall health.

Did you know that despite thousands of successful procedures annually, the human immune system can perceive a life-saving transplant as a threat? This natural but dangerous defense mechanism is precisely **what does rejection mean in medical terms**, a complex immunological response that challenges post-transplant care.

With hundreds of thousands of organ transplants performed worldwide each year, understanding transplant longevity is vital. Research shows that post-transplant care significantly impacts outcomes, making the question of **what is the most common cause of graft failure** a critical one for patients and clinicians alike.

According to the National Marrow Donor Program (NMDP), graft failure is a rare but serious complication, occurring in less than 5% of allogeneic hematopoietic stem cell transplants. A graft fails when the transplanted tissue or cells do not properly integrate or function within the recipient's body, leading to significant health consequences and complications.

The majority of organ transplants are successful, but rejection remains a lifelong risk for recipients, even with immunosuppressant medication. Understanding the signs of rejection is crucial for timely intervention. So, how do you know if your body is rejecting a transplant?

The estimated half-life of a transplanted organ is less than 15 years, largely due to a fundamental biological process. This innate response, which explains **why do our bodies reject transplants**, involves the immune system's recognition of the donor organ as foreign and its subsequent attack.

Chronic rejection poses a significant long-term challenge for many organ transplant recipients, with long-term survival for lung transplants notably lower than for other major organs due to higher rates of rejection. Understanding what is the most rejected organ transplant reveals the complex challenges faced in lung transplantation.
