Argue that you are clearly iron-deficient (especially in the setting of your other medical conditions), and that you are symptomatic. Or find another hematologist who understands iron deficiency in bariatric patients.

Suggested approach for the assessment and treatment of iron deficiency/iron deficiency anemia in clinical practice. 1In patients with inflammation, ferritin levels < 100 ng/mL should be considered as iron-deficient; 2Hb increase < 2 g/dL in 4 wk. Stein et al[6]. CHr: Hemoglobin content of reticulocytes; CRP: C-reactive protein; ESA: Erythropoiesis-stimulating agent; Hb: Hemoglobin; %HYPO: Percent hypochromic red blood cells; ID: Iron deficiency; IDA: Iron deficiency anemia; TSAT: Transferrin saturation.
***In clinical practice, iron status is mainly assessed on the basis of serum ferritin levels[182]. However, serum ferritin is subject to gender differences and falsely elevated levels in populations with inflammatory reactions since it is also an acute-phase reactant[181]. Therefore, the diagnostic workup of anemic patients (i.e., men with Hb < 13 g/dL or non-pregnant women with Hb < 12 g/dL) should include CRP, to detect underlying inflammatory reactions (suggested cut-off 5 mg/L), and TSAT (suggested cut-off 20%), a marker of low iron availability that is less affected by inflammatory reactions[181,182].
