What is Ferritin?

Ferritin is a protein found inside cells that stores iron and releases it in a controlled manner. It serves as a marker for the body's iron stores and is essential for various cellular functions, including oxygen transport and energy production. Monitoring ferritin levels helps assess iron status and diagnose conditions related to iron deficiency or overload.

Ferritin Levels

Ferritin levels indicate the amount of iron stored in the body. Low ferritin levels can signify iron deficiency, which can lead to symptoms such as fatigue, weakness, pale skin, and difficulty concentrating. High ferritin levels may indicate iron overload, which can be caused by conditions such as hemochromatosis (a genetic disorder) or chronic liver disease.

Symptoms of Low Ferritin

Symptoms of low ferritin levels (iron deficiency) include:

- Fatigue and Weakness: Iron is necessary for energy production, and low levels can lead to feelings of tiredness and weakness.
- Pale Skin: Reduced iron levels affect red blood cell production, resulting in pale or sallow skin.
- Shortness of Breath: Iron deficiency can impair oxygen transport in the blood, causing shortness of breath and dizziness.
- Difficulty Concentrating: Inadequate iron levels can impact cognitive function, causing difficulty concentrating and decreased productivity.

Causes of High Ferritin

High ferritin levels can be caused by:

- Iron Overload: Excessive dietary iron intake or conditions like hemochromatosis can lead to iron accumulation in the body.
- Chronic Inflammation: Inflammatory conditions such as rheumatoid arthritis or chronic infections can elevate ferritin levels as part of the body's immune response.
- Liver Disease: Conditions affecting the liver, such as hepatitis or alcoholic liver disease, can impair ferritin regulation and lead to elevated levels.
