Answer

Myxedema coma is associated with a higher risk of bleeding caused by coagulopathy related to an acquired von Willebrand syndrome (type 1) and decreases in factors V, VII, VIII, IX, and X. [18, 19]  Patients may also have microcytic anemia secondary to hemorrhage, or macrocytic anemia caused by vitamin B12 deficiency, or normocytic normochromic anemia, which may be secondary to decreased oxygen requirement and reduced erythropoietin.
