Graft versus host disease (GVHD) is a complex medical condition that can occur after a stem cell or bone marrow transplant. It is characterized by the donor's immune cells attacking the recipient's body, leading to a range of symptoms and complications.

The causes of GVHD are multifactorial, involving the interaction between the donor and recipient immune systems, as well as genetic and environmental factors. Diagnosis of GVHD involves a thorough assessment of the patient's medical history, physical examination, and specialized laboratory tests.
