One of the commonest complications of dengue is platelet loss. It's usually a cause for great concern since platelets or thrombocytes are life-saving blood cells whose primary function is to stop excessive bleeding caused by trauma. Whenever the body senses an injury or a broken blood vessel platelets clump together and form a blood clot to stop the bleeding. In a healthy individual the normal platelet count is anywhere between 1.5 to 4.5 lakhs. But in cases like dengue ITP or leukaemia the patient experiences a steep drop in the platelet count which can increase their chances of spontaneous bleeding.
