Having high ferritin can lead to serious health risks if it persists over a long period, as it accumulates in vital organs and causes damage.
What is Normal Ferritin?
Iron stores are known as “ferritin,” a specialized protein that stores iron within cells (especially in the liver and immune system) and releases it when needed. The ranges for normal ferritin vary by source and gender:
- Men: Estimates range from 20 to 336 ng/mL (or µg/L).
- Women: Estimates range from 10 to 307 ng/mL (or µg/L).
- Newborns: 25 to 200 ng/L.
Causes of High Ferritin in Blood
Several factors can lead to increased ferritin levels. Among the most prominent causes of high ferritin are:
- Genetic factors: Such as hemochromatosis, which causes excessive iron absorption from the intestines.
- Incorrect health practices: Overusing iron supplements or consuming alcohol.
- Medical conditions: Liver diseases, leukemia, sickle cell anemia, and thalassemia.
- Medical procedures: Frequent large-volume blood transfusions.
Risks and Damages of Excess Iron
Severe elevation can be dangerous because it leads to the deposition of the metal in body tissues, causing:
Liver and Pancreas Damage
Iron accumulates in the liver, causing cirrhosis that may initially appear without symptoms, then progress to jaundice (yellowing of the skin and eyes), nausea, and unexplained weight loss. Accumulation in the pancreas affects insulin-producing beta cells, increasing the likelihood of diabetes.
Heart Disease
Storing iron in the heart muscle leads to heart failure or cardiomyopathy, making the heart unable to pump blood efficiently. This manifests as shortness of breath and swelling in the feet.
Toxicity and Cancer
Iron poisoning can occur when excessive doses of supplements are taken (doses exceeding 60 mg/kg are sometimes fatal), destroying the digestive system and brain. Furthermore, the causes of excess iron in the body can increase the risk of cancers, especially liver and colon cancer, due to increased oxidative stress and DNA damage.
Other Complications
- Immune System: It may stimulate the growth of viruses and bacteria, weakening immunity.
- Glands and Skin: Hypothyroidism and skin discoloration to a gray or bronze hue.
- Bones and Joints: Arthritis and osteoporosis.
- Sexual Health: Erectile dysfunction and early menopause.
How to Lower High Iron Levels?
Based on medical guidance, the following instructions can be followed to reduce the excess:
- Donate blood regularly to remove excess iron.
- Avoid dietary supplements containing iron or Vitamin C (which increases absorption).
- Reduce the intake of red meats and use non-iron cookware.
- Drink coffee and green tea, and eat foods rich in calcium, zinc, and magnesium to inhibit iron absorption.
Frequently Asked Questions
What does high ferritin level indicate?
It is dangerous if it is severe or chronic, as it causes liver and heart failure and increases the chances of developing diabetes and cancer.
What are the symptoms of high iron?
Initial symptoms include stomach pain, general fatigue, joint pain, and increased heart rate, in addition to a bronze skin color in cases of hemochromatosis.
Why is there high iron with low hemoglobin?
This may occur in conditions such as thalassemia or sickle cell anemia, where the patient requires frequent blood transfusions to compensate for the hemoglobin deficiency, gradually leading to iron accumulation in the body.
When Should You Visit a Doctor?
Seek medical consultation immediately if the following signs appear:
- Yellowing of the skin or whites of the eyes (jaundice).
- Noticeable swelling in the legs and feet accompanied by shortness of breath.
- Sudden and unexplained weight loss.
- Appearance of a bronze or gray color on the skin.
