Bleeding Diathesis


In medicine bleeding diathesis is an unusual susceptibility to bleed mostly due to hypocoagulability (a condition of irregular and slow blood clotting), in turn caused by a coagulopathy (a defect in the system of coagulation). Therefore, this may result in the reduction of platelets being produced and leads to excessive bleeding. Several types of coagulopathy are distinguished, ranging from mild to lethal. Coagulopathy can be caused by thinning of the skin, such that the skin is weakened and is bruised easily and frequently without any trauma or injury to the body. Also, coagulopathy can be contributed by impaired wound healing or impaired clot formation.

Acquired causes of coagulopathy include anticoagulation with warfarin, liver failure, vitamin K deficiency and disseminated intravascular coagulation. Additionally, the haemotoxic venom from certain species of snakes can cause this condition, for example Bothrops, rattlesnakes and other species of viper. Viral haemorrhagic fevers include dengue hemorrhagic fever and dengue shock syndrome.
