Many fractures, low hct, low hgb, low rbc... can the fractures cause the other three? (wbc and platelets are normal. on anticoagulant lovenox)

The opposite: B"sd that combination certainly needs to be looked into, imagine it already has. Fractures will not cause anemia, but a cause of pathological or other categories of fracture can be due to conditions that cause anemia - most commonly multiple myeloma. For sure you should have a thorough evaluation. As an endocrinologist am consulted on bone and mineral metabolism. would be glad to help
