Platelets are small cells in the body which help the blood to clot. There are three types of cells, red cells, white cells and platelets in the cells. These blood cells called platelets help the blood to clot. Whenever we have a small cut, it helps the blood to clot. The platelets are instrumental in forming the clot. Whenever the platelet count goes down, there is a risk of bleeding, but then again, people have a lot of myths about platelets though the normal platelet count is one lakh fifty thousand, to four lakh fifty thousand, unless and until the platelet count falls to less than 20000 or 10000. There will not be any risk of significant internal bleeding. The most common cause if low platelet count, nowadays we see is due to dengue fever. But apart from infections. The most common cause of low platelet count Is immune thrombocytopenia where our own immunity destroys our platelets. So we give medicines to suppress the immunity and to prevent the platelet destruction. That condition is called as ITP or immune thrombocytopenia. In ITP, the goal of treatment is to keep the platelet count at a safe level, which is anywhere more than 30000. The dictum of treatment in ITP is do not treat the platelet counts, treat the symptoms.
