Learn how to recognize and treat low iron levels, including signs, causes, and treatment options such as iron-rich foods and supplements.


Iron is a vital nutrient for the body, as it helps build red blood cells that carry oxygen throughout the body. Low iron levels can lead to anemia, which in turn, can cause fatigue, shortness of breath, and other complications. In this article, we will discuss the signs, causes, and treatment of low iron levels.

Symptoms of Low Iron

The signs and symptoms of low iron can be mild to severe, and they can vary from person to person. Some common symptoms include:

  • Fatigue and weakness
  • Pale skin
  • Shortness of breath
  • Dizziness or lightheadedness
  • Irritability
  • Spoon-shaped nails
  • Craving for nonfood items, such as dirt, ice, or starch

If you are experiencing any of these symptoms, it’s essential to seek medical attention. Low iron levels can be diagnosed through a blood test, and left untreated, they can lead to more severe complications such as heart problems.

Causes of Low Iron

There are several different reasons why someone may have low iron levels, such as:

  • Inadequate iron intake
  • Blood loss due to menstruation, childbirth, or an injury
  • Inability to absorb iron from food
  • Chronic diseases such as kidney disease or cancer
  • Pregnancy and breastfeeding, which increases iron needs
  • Medications that interfere with iron absorption, such as antacids or proton pump inhibitors

To address an underlying medical issue or to increase iron intake, it is essential to consult with a healthcare provider. They may prescribe iron supplements or recommend dietary changes to increase absorption.

Testing for Low Iron

There are several different ways to identify low iron levels through blood tests:

  • Serum Iron Test: This test measures the amount of iron in the blood.
  • Ferritin Test: This test measures the amount of ferritin, a protein that stores iron in the body.
  • Transferrin Saturation Test: This test measures the amount of transferrin, a protein that transports iron in the blood.
  • Complete Blood Count (CBC): This test measures the number of red blood cells, hemoglobin, and hematocrit in the blood, which can indicate anemia.

If you are experiencing symptoms of low iron, it’s important to speak with your healthcare provider about when to get tested and how to interpret the test results.

Iron-Rich Foods

In addition to iron supplements, there are many iron-rich food options to add to one’s diet. Some foods to consider include:

  • Red meat, such as beef, pork or lamb
  • Poultry, such as chicken or turkey
  • Seafood, such as clams, oysters, and sardines
  • Beans and lentils
  • Tofu and tempeh
  • Dark green leafy vegetables, such as spinach and kale
  • Fortified cereals and bread
  • Nuts and seeds, such as cashews, pumpkin seeds, and quinoa

It’s important to add these iron-rich foods to one’s diet, especially if you are diagnosed with anemia.

Treating Low Iron

The first step to treating low iron levels is to increase iron intake through dietary changes or supplements. However, some people may need more intensive treatments, such as:

  • Intravenous (IV) Iron Therapy: This is administered through an IV and is reserved for individuals who cannot take iron supplements or are experiencing severe iron deficiency anemia.
  • Blood Transfusion: This is a last resort treatment and is used for individuals with severe anemia who need immediate relief.

It’s important to speak with a healthcare provider before starting any iron supplement or making any dietary changes. They can provide advice on safe supplementation and when to seek medical attention for more intensive treatments.


In conclusion, low iron levels can cause various symptoms, ranging from mild to severe. It’s important to recognize and seek medical attention for these symptoms. Causes of low iron include inadequate iron intake, blood loss, and chronic diseases. Testing for low iron can be done through blood tests. Iron-rich foods can be added to one’s diet, and low iron levels can be treated through dietary changes or supplements. In some cases, more intensive treatments may be necessary. If you suspect that you may have low iron levels, speak to your healthcare provider about the best course of action.
