Von Willebrand disease (VWD) is a disorder that reduces your blood’s clotting ability. This is usually caused by a lack of the protein Von Willebrand factor (VWF) but it can also be caused if the VWF proteins in your body are faulty and don’t work as well as they should. People suffering from VWD will find that if they cut themselves, have a bloody nose, or undergo surgery, they bleed excessively, making it very hard to stem any bleeding.
At some point in your life you may develop hemorrhoids. The first time it happens it may be indicated by a simple blood smear on your toilet paper, (it may be harder for women to detect and they might think their period is out of cycle), to a full toilet bowl of bright red blood. Both can be a cause for alarm if you’re young and don’t have a history of hemorrhoids.
