Red Blood Cell Deficiency — Which Doctor Should I See?

Red blood cell deficiency, or anemia, occurs when your body lacks enough healthy red blood cells to carry oxygen to tissues. This can cause fatigue, weakness, and shortness of breath.

Common causes include iron deficiency, vitamin B12 or folate deficiency, chronic diseases, blood loss, bone marrow disorders, and certain medications that affect RBC production.

Treatment depends on the cause and may include iron supplements, vitamin B12 injections, dietary changes, blood transfusions, or medications to stimulate RBC production.
