Platelet anemia, a bleeding disorder that occurs when the aggregation function of platelets is reduced. Platelets have the function of aggregation, and this function is achieved through the glycoproteins on the platelets. If the glycoproteins on the platelet membrane are missing or function abnormally, the platelets cannot aggregate together and cannot fully play their role in stopping bleeding, and platelet anemia occurs. Patients with platelet anaemia rarely experience spontaneous bleeding, often when they are traumatized, the bleeding symptoms are more pronounced. Some women experience more than one period after they reach their menstrual period, and finally, after examination, they are diagnosed with platelet anaemia. Patients with thrombocytopenia have a tendency to gradually remit as they age. They need to prevent trauma in their daily lives to reduce the possibility of bleeding. If there is excessive menstruation, medication such as progesterone can be applied, and platelet transfusion can also be used to treat the condition if necessary.
