Graft-versus-host disease (GVHD) is a common complication after an allogeneic transplant, a transplant in which cells from a family member, unrelated donor or cord blood unit are used.

Diabetes insipidus (die-uh-BEE-teze in-SIP-uh-dus) is an uncommon disorder that causes an imbalance of water in the body. This imbalance leads to intense thirst even after drinking fluids (polydipsia), and excretion of large amounts of urine (polyuria). While the names diabetes insipidus and diabetes mellitus sound similar, they're not related. Diabetes mellitus — which can occur as type 1 or type 2 — is the more common form of diabetes. There's no cure for diabetes insipidus, but treatments are available to relieve your thirst and normalize your urine output.

Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities. Two types of white blood cells, T and B cells (lymphocytes), are also produced in the lymph nodes and spleen, and T cells are produced and mature in the thymus gland.
The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS).

When you get a kidney transplant, a healthy kidney is placed inside your body to do the work your own kidneys can no longer do.
