A woman was diagnosed with von Willebrand disease after several physician evaluations. The first sign was frequent nosebleeds when she was a child. The next was prolonged menstrual cycle of 21 days which started when she was 13 years old. The disease was discovered by Finnish doctor Erik von Willebrand in 1926 after a 13-year-old girl died on her fourth menstrual cycle. The disease, unlike hemophilia, which occurs in males only, occurs in both males and females. Postpartum bleeding can occur three to four weeks after delivery but can be helped by DDAVP and Factor VIII concentrates.
