Editing Crohn's disease (section)

====Endocrinological or hematological====

[[Leukocytosis]] and [[thrombocytopenia]] are usually due to [[immunosuppressant]] treatments or [[sulfasalazine]]. Plasma [[erythropoietin]] levels often are lower in patients with IBD than expected, in conjunction with severe [[anemia]].<ref name="Manifestations" />

[[Thrombocythemia|Thrombocytosis]] and [[thromboembolic]] events resulting from a [[Thrombophilia|hypercoagulable]] state in people with IBD can lead to [[pulmonary embolism]] or [[thrombosis]] elsewhere in the body. Thrombosis has been reported in 1.8% of people with ulcerative colitis and 3.1% of people with Crohn's disease. Thromboembolism and thrombosis are less frequently reported among children, with three people with ulcerative colitis and one with Crohn's disease described in case reports.<ref name="Manifestations" />

In rare cases, hypercoagulation disorders and [[portal vein thrombosis]] have been described.<ref name="Manifestations" />
