Bleeding Disorders

Bleeding disorders are broadly classified as congenital (inherited) or acquired:

• Congenital bleeding disorders are caused by defects or damage in a developing fetus. Congenital defects can be due to inherited abnormalities in genes or chromosomes or to intrauterine conditions, such as infections.
• Acquired bleeding disorders are those that develop or spontaneously occur in the individual.
