There are multiple causes, depending on the type of blood problem. In many cases, blood disorders are genetic and passed along from parents to their children. Certain medications or diseases can also lead to blood disorders. In addition, people can develop blood disorders if their diet is lacking in certain nutrients, such as iron.

Symptoms of blood disorders can vary widely depending on the nature of the illness, and what component of the blood is impacted. For many disorders, weakness, fatigue or shortness of breath are common symptoms. If decreased white blood cells are present, the person may get more frequent infections. Trouble with bleeding and bruising can occur with clotting disorders. Headaches and dizziness are other issues that occur sometimes with blood disorders.
