Low Iron: What It Means and What to Do Next
Low iron (below 60 mcg/dL) with high TIBC confirms iron deficiency — the most common nutritional deficiency worldwide. Low iron affects energy, cognition, hair growth, and immunity. It can exist months before causing anemia, which is why testing both iron and ferritin is important.
What Causes Low Iron?
Inadequate Dietary Intake
Low consumption of iron-rich foods (red meat, legumes, fortified grains). Common in vegetarians and restrictive diets.
Blood Loss
Heavy menstrual periods, GI bleeding (ulcers, colon polyps), and frequent blood donation are leading causes.
Malabsorption
Celiac disease, inflammatory bowel disease, H. pylori infection, and gastric bypass reduce iron absorption.
Increased Demand
Pregnancy, adolescent growth, and endurance athletics increase iron requirements beyond normal intake.
Associated Symptoms
What to Do Next
1. Retest to confirm
A single abnormal result should be confirmed with a repeat test. Temporary factors like stress, illness, or medications can affect results.
2. Related tests to consider
3. When to see a doctor
If your Iron is significantly abnormal, if you have severe symptoms, or if repeated results confirm the abnormality, consult a healthcare professional for appropriate evaluation and treatment.
