Why is Ferritin High? Causes, Symptoms, and What to Do

Ferritin is a protein that stores iron in your body and releases it when your body needs it. Measuring ferritin levels can help understand how much iron is stored in your body. High ferritin levels can indicate various health conditions, and understanding these can help you and your healthcare provider decide on the next steps.

What is Ferritin?

Ferritin is a protein that stores iron and releases it in a controlled manner. It is mainly found in the liver, spleen, and bone marrow. A blood test can measure the amount of ferritin in your blood, which reflects the total amount of iron stored in your body. Ferritin levels can vary between individuals, and several factors can influence these levels.

Why High Ferritin Levels Matter

High ferritin levels can indicate an excess of iron in the body. This condition is known as hemochromatosis, a genetic disorder where the body absorbs too much iron from the diet. However, high ferritin can also be a sign of inflammation, liver disease, or other medical conditions. It is important to identify the underlying cause to address potential health issues effectively.

Causes of High Ferritin Levels

There are several reasons why ferritin levels might be elevated:

• Hemochromatosis: A genetic disorder causing excess iron absorption.
• Chronic Inflammation: Conditions like rheumatoid arthritis or infections can increase ferritin.
• Liver Disease: Liver damage from conditions like hepatitis or alcohol abuse can raise ferritin levels.
• Frequent Blood Transfusions: These can lead to iron overload.
• Other Conditions: Certain cancers and metabolic disorders can also increase ferritin.

Symptoms of High Ferritin Levels

While high ferritin itself may not cause symptoms, the underlying condition might. Symptoms can include fatigue, joint pain, abdominal pain, and skin changes like a bronze or gray color. If high ferritin is due to hemochromatosis, symptoms may also include diabetes, heart problems, and liver issues.

How to Read Ferritin Test Results

Ferritin levels are measured in nanograms per milliliter (ng/mL). Normal ranges can vary widely between different labs, but generally, for men, the range is 30–300 ng/mL, and for premenopausal women, it is 13–150 ng/mL. If your ferritin level is above these ranges, it might be considered high, but interpretation should always be done by a healthcare provider who can consider your overall health and other test results.

Frequently asked questions

What does a high ferritin level mean? High ferritin levels suggest an excess of iron in the body or an inflammatory condition, but it requires further investigation to determine the exact cause.

Can diet affect ferritin levels? Yes, consuming foods high in iron, like red meat, can increase iron levels, but a high ferritin level is often due to other underlying health issues.

How is high ferritin treated? Treatment depends on the cause. For hemochromatosis, regular blood removal (phlebotomy) is a common treatment. Other conditions might require different approaches.

When to see a doctor

If you receive a test result showing high ferritin levels, it's important to discuss this with your healthcare provider. They can help determine the cause and whether further testing or treatment is needed. Symptoms like unexplained fatigue, joint pain, or skin changes should also prompt a medical consultation.
