Question and answer
Unnecessary hysterectomies due to undiagnosed bleeding disorder in women: The bleeding disorder
called Von Willebrand's disease is quite common in women, but often fails to be correctly diagnosed.
Women with the condition tend to have heavy periods, since they actually have a bleeding disorder.
Severe afflictions may result in the women receiving a hysterectomy unnecessarily, when the
underlying cause has not been identified.
See the introduction to Von Willebrand's disease and bleeding disorder.
Sinusitis is overdiagnosed: There is a tendency to give a diagnosis of sinusitis,

This is particularly dangerous for babies too young to be vaccinated,
and any un-vaccinated children.
