A researcher from the Leiden University Medical Center in the
Netherlands has reported that particular blood types may be risk
factors for deep-vein thrombosis (DVT). Dr. Vania Morelli
maintains that people with blood type A, B or AB are more
susceptible to DVT. “A non-O blood type strongly increases the
risk in people who carry a variant of a protein (called Factor V
Leiden) involved in blood clotting.” Dr. Morelli also suggested
that awareness of one’s blood type might be a means of improving
DVT management. Dr. Morelli presented her findings at the XXth
Congress of the International Society on Thrombosis and
Haemostasis, held August 6-12 in Sydney, Australia. Source:
