Anemia is a condition that develops when you don’t have enough healthy red blood cells to carry enough oxygen to your body's tissues. There are many forms of anemia, and each form has its own cause. Anemia can be a short-term or long-term condition with mild to severe symptoms.
Bleeding disorders are conditions that results when the blood fails to form a proper blood clot. The clotting factors or platelets in the blood don’t function normally or exist in short supply. When the blood does not clot properly, excessive or persistent bleeding can occur. The most common bleeding disorders include Hemophilia A and B, Factor II, V, VII, X or XII deficiencies, and Von Willebrand’s disease. If blood tends to clot too much, it is referred to as hypercoagulable state or thrombophilia. People with hypercoagulable status have an increased risk for blood clots.
Thrombocytopenia is a condition caused by a low platelet count in the blood. Since platelets help your blood clot, a low platelet count can cause spontaneous bleeding in gums, eyes, the bladder, or after an injury. It can range from mild to severe.
Neutropenia occurs when there are too few neutrophils, a type of white blood cells, in your body. White blood cells help your body fight infections, but neutrophils specifically fight certain infections caused by bacteria. Neutropenia can cause a person to be more vulnerable to infections.
Polycythemia vera is a rare type of blood cancer where your body produces too many red blood cells. Since red blood cells are responsible for carrying oxygen throughout your body, too many red blood cells causes your blood to thicken and flow more slowly. Life-threatening complications can occur with polycythemia vera because blood that flows more slowly reduces the amount of oxygen to your brain, heart and other vital organs.
Essential thrombocythemia is a disorder in which your body produces too many blood platelets. Having too many blood platelets can increase your risk of blood clots. The condition can cause you to feel frequently tired and lightheaded, plus, you might experience headaches and vision changes.
