5 symptoms of an iron deficiency

Are you plagued with fatigue or exhaustion throughout the day? It could be the result of an iron deficiency. 

Iron is an essential mineral that helps red blood cells transport oxygen from the lungs to the organs and tissues. This is important because every cell in the body needs oxygen to function properly.

However, blood loss, poor diet or reduced iron absorption can cause iron levels to drop too low. This can lead to an iron deficiency. Iron deficiency is the most common nutritional deficiency in the United States and the leading cause of anemia.

Most people don't realize they have iron deficiency until a blood test reveals it. However, there are a few symptoms to look out for.

1. Fatigue. Fatigue is one of the most common symptoms of iron deficiency, but it can be easy to overlook. 

If you've been extremely fatigued for more than a month, consult your doctor. Weakness, irritability and trouble focusing may be warning signs.

2. Feeling cold. Cold hands and feet can be a result of iron deficiency anemia. People with anemia have poor circulation because they lack enough red blood cells. These cells carry oxygen throughout the body.

3. Chewing ice.  Another symptom of iron deficiency is an intense craving for ice. This condition, called pagophagia, is a form of pica. An eating disorder that causes people to eat substances that have no nutritional value.

People with pagophagia eat several cups or pounds of ice every day.

One study published in the journal Medical Hypotheses suggests that eating ice may boost energy in people with iron deficiency.

4. Restless legs symptoms. Some people with iron deficiency experience restless legs syndrome. This neurological disorder causes an irresistible urge to move the legs. It can also cause sharp pain, numbness and tingling in the legs.

5. Eating dirt. A severe iron deficiency can cause people to crave or eat dirt, another form of pica. This symptom is often seen in the South or among pregnant women.

Treating an iron deficiency

If you are suffering from an iron deficiency, there are several methods of treatment. Your doctor may recommend:

• Eating more iron-rich foods. Foods associated with an iron-rich content would be red meats, dark leafy greens, pistachios and beans, especially for vegetarians.
• Taking iron supplements. Iron supplements provide your body with the recommended daily intake of iron. However, they can also cause unwelcome side effects, like constipation.
• Getting iron infusions. Doctors recommend iron, or heme, infusions for people who have trouble absorbing iron. They may also help after colon surgery.
