Overview

Iron deficiency anemia causes can be broadly divided into physiological causes as that seen during growth and pregnancy and due to pathological process. The pathological process could be further divided based on blood loss and inadequate iron absorption.

Causes

Life threatening causes

Severe blood loss such as traumatic haemorrhage, haemetemesis, haemoptysis or uncontrolled bleeding from any body part can result in death from hypovolemic shock^[1]^[2]^[3]^[4]

^[5]^[6]^[7]^[8]^[9]^[10]^[11]^[12]^[13] .

Most common causes

Less common causes

Erythrpoetin/eryhtropoetin stimulating drugs
Leflunomide
Pramipexole
Trientine

Genetic cause

IRIDA- iron referactory iron deficiency anemia due to TMPRSS6 mutation
SLC11A-2 mutation
Iron-refractory iron deficiency anaemia •
Divalent metal transporter deficiency anaemia, •
Fanconianaemia
Pyruvate kinase deficiency

Pathological

Blood Loss

Menstruation
Gastrointestinal tract (Bleeding from the gastrointestinal tract (ulcers, hemorrhoids, Esophageal varices, The use of aspirin, ibuprofen, or arthritis medicines for a long time, Cancer in the esophagus, stomach, or colon)
- Food sensitivity
- Hookworms
Genitourinary tract
Respiratory tract (Rarely laryngological bleeding or from the respiratory tract)
Blood donation

Inadequate Iron Absorption

Dietary deficiency
Impaired absorption (Celiac disease, Crohn's disease)
- Intestinal malabsorption
- Gastric surgery
- Hypochorhydria
Taking too many antacids that contain calcium
