Von Willebrand disease (vWD) can be a mild disorder associated with few, if any, symptoms. Sometimes people are not diagnosed until they have excessive bleeding following a serious injury, accident, (invasive) dental work, or surgery. In other cases, diagnosis of one family member may lead to a diagnosis in other family members as well. Some patients with rarer types of vWD can have more severe or frequent bleeding.
Bleeding usually involves the mucous membranes, the delicate tissues that line such body passages as the nose, mouth, uterus, vagina, stomach and intestines.
Some of the usual symptoms of vWD include frequent nosebleeds, easy bruising, heavy menstrual flow, and excessive bleeding following surgery, childbirth, or dental work.
