Hepatitis C can also cause some rare problems (problems which do not happen very often), which affect parts of the body outside of the liver. One rare problem that Hepatitis C can cause is Sjögren's syndrome, an autoimmune disorder (or a disorder where the body's system of defenses attacks itself). Hepatitis C can also cause a lower-than-normal number of blood platelets (the part of the blood which causes blood to clot; without enough platelets, a person can have bleeding problems, or can start bleeding and be unable to stop. Other rare problems that Hepatitis C can cause are chronic (long-lasting) skin disease; non-Hodgkin's lymphoma (a type of cancer); and diabetes (where a person's body does not make or use enough insulin, an important hormone that controls the level of sugar in the blood).
