A hemoglobin level this low is life threatening!! Hemoglobin is a protein found in red blood cells that uses iron to bind oxygen and deliver it to tissue throughout the body. Causes of low hemoglobin include bleeding, nutritional deficiencies (e.g. iron deficiency), increased breakdown (hemolysis), chronic disease, and cancer. P.S. We raised over $800,000 for cancer research tonight 🤯🤯🫶🫶 Honored to have emcee’d the #cowtownsummersoirée again!! Thank you to @creelfamilyphilanthropies for your
