We often hear that if one is down with fever, watch out one’s platelet count.
What are platelets?
Platelets are minute, irregularly shaped bodies that act like sticky chemical plugs that stop blood from leaking out of our blood vessels.
Platelets play an important role in blood clot formation.
When there is an injury in the wall of a blood vessel (like suffering from a paper cut), platelets in the blood gather around the wound and set off a cascade of chemical processes to form a clot that will effectively stop the bleeding.
If one has too much platelets, it is easier for blood clots to form inside blood vessels and cut of blood supply to important organs.
If one has too little platelets, one might be at risk for excessive bleeding.
