Constant tiredness, pale skin, and chest pains are all common signs of low iron levels, also known as iron deficiency anemia. Anemia is a condition that develops when your blood lacks enough healthy red blood cells to deliver oxygen around the body and according to the World Health Organization (WHO), iron deficiency anemia is the most common nutritional disorder in the world [1].

It’s estimated that around 10 million people in the United States are iron deficient and around 5 million of those have iron deficiency anemia. With those numbers in mind, it’s important to know more about iron deficiency and whether or not you’re getting enough iron.

What is the main cause of iron deficiency anemia?

Iron deficiency anemia is caused by a lack of the essential mineral: iron. This condition occurs when your body isn’t getting enough iron to produce hemoglobin - a key component in red blood cells.

You can be deficient in iron for a number of reasons, including diet or blood loss. Some common causes include:

Blood loss

During a heavy menstrual cycle, women can lose iron nearly every month through blood loss. Other forms of blood loss that can cause iron deficiency anemia include slow, chronic blood loss such as a colon polyp or gastrointestinal bleeding.

Not consuming enough iron

One of the best ways to provide your body with the iron that it needs is through iron-rich foods. In fact, it’s possible to reduce your risk of iron deficiency or even manage iron levels by consuming iron-rich foods. Some of these include:

  • Iron-fortified foods
  • Red meat
  • Dark green leafy vegetables
  • Dried fruits
  • Nuts

Inability to absorb iron

If a person is living with an intestinal disorder that affects their intestine’s ability to absorb nutrients from food, it can lead to iron-deficiency anemia. Examples of these disorders include celiac disease or chron’s disease.

What are the symptoms of iron deficiency anemia?

At times, iron deficiency can go unnoticed due to its lack of symptoms though as it worsens, indicators begin to become more apparent. According to Mayo Clinic, some of these may include [2]:

  • Extreme fatigue
  • Weakness
  • Pale skin
  • Chest pain, fast heartbeat or shortness of breath
  • Headache, dizziness or lightheadedness
  • Cold hands and feet
  • Brittle nails

Can you fix iron deficiency?

While iron deficiency can’t be fixed quickly, or overnight, there are some steps that can be taken towards helping reduce your risk of developing the condition or managing it if you have already been diagnosed, these include:

  • Eating more iron-rich foods
  • Choosing foods and drinks that help with iron absorption
