Q

Anemia

A

Anemia results from a lack of red blood cells or dysfunctional red blood cells in the body. This leads to reduced oxygen flow to the body’s organs.

Possible causes include low iron, low vitamin B, blood loss, reduced blood formation.

Q

Polycythemia

A

An abnormally increased concentration of hemoglobin in the blood, through either reduction of plasma volume or increase in red cell numbers.

It may be a primary disease of unknown cause, or a secondary condition linked to respiratory or circulatory disorder or cancer.

Q

Thrombocytosis

A

Thrombocytosis is a disorder in which your body produces too many platelets (thrombocytes), which play an important role in blood clotting. The disorder is called reactive thrombocytosis or secondary thrombocythemia when it’s caused by an underlying condition, such as an infection.

Q

Thrombocytopenia

A

Thrombocytopenia is a condition in which you have a low blood platelet count.

It often occurs as a result of a separate disorder, such as leukemia or an immune system problem. Or it can be a side effect of taking certain medications
