Ferritin is an important protein that stores iron in the body. It is found mainly in the liver, spleen, and bone marrow. Ferritin levels in the blood can help diagnose iron deficiency anemia.

Low levels of ferritin can cause a range of symptoms such as fatigue, weakness, hair loss, and difficulty concentrating. In this article, we will discuss the causes of low ferritin and how to manage it.

Causes of Low Ferritin

Iron Deficiency Anemia

Iron deficiency anemia is a common cause of low ferritin levels. This is because ferritin stores iron in the body, and iron is needed to make red blood cells.

In iron deficiency anemia, the body does not have enough iron to make hemoglobin, which carries oxygen to the body’s cells. This can cause fatigue, weakness, pallor, and shortness of breath.

Blood Loss

Regular blood loss can cause low ferritin levels over time. Women who have heavy periods may be at risk for iron deficiency anemia and low ferritin levels. Blood loss during childbirth or surgery can also cause a decrease in ferritin levels.

Dietary Factors

Low iron intake can lead to low ferritin levels. Vegetarians and vegans may be at risk for iron deficiency anemia and low ferritin levels because plant-based foods are not as rich in iron as meat and poultry.

Children and infants who are not getting enough iron in their diet also may have low ferritin levels.

Chronic Diseases

Chronic diseases can interfere with iron absorption and utilization in the body, leading to low ferritin levels. Inflammatory bowel disease, celiac disease, and kidney disease are some examples of chronic diseases that can cause low ferritin levels.

Pregnancy

Pregnancy increases the blood volume in the body, which requires more iron to support the developing fetus. If a pregnant woman does not get enough iron from her diet, she may develop iron deficiency anemia, which can lead to low ferritin levels.

Parasitic Infections

Parasitic infections such as hookworms can cause low ferritin levels. These parasites feed on the blood in the intestines, causing blood loss and anemia.

This can lead to low ferritin levels as ferritin levels decrease in response to the decreased iron stores in the body.

Autoimmune Disorders

Autoimmune disorders such as rheumatoid arthritis and lupus can cause inflammation in the body, which can interfere with iron absorption and utilization. This can lead to low ferritin levels over time.

Medications

Some medications can interfere with iron absorption and utilization, leading to low ferritin levels. Antacids, proton pump inhibitors, and certain antibiotics are some examples of medications that can cause low ferritin levels.

Heredity

Some people may have a genetic predisposition to low ferritin levels. This can be due to mutations in the genes that regulate iron absorption and utilization in the body.

Managing Low Ferritin

The treatment for low ferritin depends on the underlying cause. If the cause is iron deficiency anemia, iron supplements and dietary changes may be recommended. If the cause is a chronic disease, treating the disease may help improve ferritin levels.

In some cases, intravenous iron infusions may be necessary if oral iron supplements are not effective.

Eating a diet rich in iron can help prevent low ferritin levels. Foods that are rich in iron include red meat, poultry, seafood, beans, lentils, tofu, spinach, and fortified breakfast cereals.

Vitamin C can also help improve iron absorption, so it’s important to eat plenty of fruits and vegetables.

Avoiding foods and substances that can interfere with iron absorption is also important. This includes coffee, tea, and calcium-rich foods. Taking iron supplements with food and avoiding antacids and proton pump inhibitors can improve absorption.

Conclusion

Low ferritin levels can be caused by a variety of factors including iron deficiency anemia, blood loss, dietary factors, chronic diseases, pregnancy, parasitic infections, autoimmune disorders, medications, and heredity.

Managing low ferritin involves identifying and treating the underlying cause and making dietary and lifestyle changes to improve iron absorption. If you are experiencing symptoms of low ferritin, it’s important to talk to your healthcare provider about getting tested and finding the appropriate treatment.
