6 Signs You May Be Iron-Deficient

Feeling constantly tired, foggy, or unusually short of breath might be more than stress or a busy schedule. Iron deficiency is the most common nutritional deficiency in the United States. 

Children and women of childbearing age are at a higher risk of developing iron deficiency, and it often goes undiagnosed. 

At the internal medicine practice of Samuel I. Fink, MD, FACP, in Tarzana, California, patients receive comprehensive care. Dr. Fink takes time to get to the root of your symptoms through detailed evaluations, in-house diagnostics, and a personalized care approach. 

Here’s how to spot the signs of iron deficiency, and what to do if you suspect that you or a loved one may be iron-deficient.

1. You feel wiped out no matter how much you sleep

If you're dragging yourself out of bed every morning, even after a full night’s rest, low iron may be to blame. 

Iron is essential for your body to make hemoglobin, the protein in red blood cells that transports oxygen throughout your body. Without enough of it, your tissues and muscles don’t get the oxygen they need to function well, leading to constant fatigue that sleep alone can’t fix.

2. You look unusually pale

If your complexion appears dull, washed out, or less vibrant than usual, it could be linked to low iron. Hemoglobin gives blood its red color, which helps give skin a healthy tone. You might also notice paleness in your gums, lips, or even the inside of your lower eyelids.

3. You get winded easily

Exercise intolerance is incredibly common in patients with inadequate iron. If climbing stairs or walking across a parking lot leaves you short of breath, iron deficiency could be the reason. 

With less hemoglobin available to transport oxygen, your heart and lungs have to work harder to keep up, making normal activities feel like a workout. This can happen even if you’re otherwise healthy and in decent shape.

4. Your brain feels foggy or unfocused

Iron plays a key role in brain function. When you’re deficient, you may have trouble concentrating, remembering things, or staying mentally sharp. This brain fog can be especially frustrating if it affects your work or daily decision-making. 

In some cases, people also experience mood swings or increased irritability.

5. Nail and hair changes

Keep a close eye on changes in your nails and hair. Brittle nails, hair thinning, or unexpected hair loss may be linked to iron deficiency. 

Since iron helps fuel cell growth and repair, your hair follicles and nail beds can suffer when levels are low. You may also notice increased nail ridges, or your nails may break more easily than usual.

6. Changes in food cravings

Unusual cravings for non-food substances like ice, dirt, or starch can be a condition called pica, which is sometimes associated with iron deficiency. On the flip side, many people with low iron experience a reduced appetite, especially in more advanced stages of deficiency.

Next steps you shouldn’t skip

If these signs seem familiar, don’t brush them off or self-diagnose with supplements. The best first step is a medical evaluation, which may include a blood test to check your iron and ferritin levels.
