A ferritin blood test can also help your doctor figure out whether your body is storing too much iron. High levels may point to alcohol abuse, infection, liver disease, rheumatoid arthritis, overactive thyroid, or some types of cancer. Symptoms of high iron levels vary and can include: Exhaustion.

Athletes lose more iron due to heavy sweating as well as increased blood loss in the urine and GI tract. * Red blood cells also break down more quickly in those who exercise.

You should fast for 8 hours before having an iron level blood test. This is to ensure that levels of iron detected in your blood are not skewed by food or drink intake. If you're having a blood test for ferritin levels – a measure of how much iron is stored in the body – you don't usually need to fast before.

Other causes of anemia include a deficiency of iron, folic acid, or vitamin B12. Chronic diseases such as diabetes or kidney disease can also cause anemia. To confirm a diagnosis of anemia, your doctor will give you a blood test. If iron deficiency is the cause of your fatigue, treatment may include iron supplements.

Long-term consumption of excessive amounts of alcohol greatly increases your risk of iron overload. The primary result of alcohol-related iron overload is the potentially fatal disorder alcoholic liver disease.

A ferritin test helps your doctor understand how much iron your body stores. If a ferritin test reveals that your blood ferritin level is lower than normal, it indicates your body's iron stores are low and you have iron deficiency. As a result, you could be anemic.

High levels may be caused by: Too little water in the body (dehydration). High levels of salt or sugar in the blood. This may be caused by problems such as poorly controlled diabetes.

Over time, diets low in iron may cause a deficiency. Likewise, an overdose of iron supplements may cause severe iron poisoning. Bottom Line: The rate of iron absorption from the digestive tract is tightly regulated by the hormone hepcidin. However, several iron overload disorders may disrupt this fragile balance.

Iron is an important component of hemoglobin, the substance in red blood cells that carries oxygen from your lungs to transport it throughout your body. Hemoglobin represents about two-thirds of the body's iron. If you don't have enough iron, your body can't make enough healthy oxygen-carrying red blood cells.

Thick blood is caused by heavy proteins, or by too much blood in the circulation. Too many red cells, white cells, and platelets will result in blood thickening. Another cause is an imbalance in the blood clotting system.

If your body doesn't have enough iron, it cannot produce enough healthy oxygen-carrying red blood cells. Iron deficiency can cause anemia, which means you have too little hemoglobin. Women in their childbearing years are at higher risk for iron deficiency because of the loss of blood during menstruation.

Iron overload: Iron overload is a health effect caused by a mutation in the gene responsible for digesting iron. While this disorder isn't extremely common, it's still a reason to consider removing iron from water. Iron overload can lead to hemochromatosis — which can cause damage to the liver, heart, and pancreas.

Medical conditions that can cause high hemoglobin levels include: Polycythemia vera (the bone marrow produces too many red blood cells) Lung diseases such as COPD, emphysema or pulmonary fibrosis (lung tissue becomes scarred) Heart disease, especially congenital heart disease (the baby is born with it) Kidney tumors.

A high hemoglobin count occurs most commonly when your body requires an increased oxygen-carrying capacity, usually because: You smoke. You live at a high altitude and your red blood cell production naturally increases to compensate for the lower oxygen supply there.

There are several types of anemia; however, iron-deficiency anemia is most often linked to cancer. Iron-deficiency anemia is caused by a lack of healthy red blood cells in the body. Read on to learn more about the anemia-cancer connection.

Instead, it may be caused by the rupture of blood cells in the blood sample during or shortly after the blood draw. The ruptured cells leak their potassium into the sample. This falsely raises the amount of potassium in the blood sample, even though the potassium level in your body is actually normal.

Iron deficiency is the most common cause of anemia globally, but the leading causes of anemia vary widely by geography, age, and sex (Kassebaum et al. 2014). Other nutrients—vitamin A, folate, vitamin B12, and zinc—play specific roles in the production of red blood cells, or indirectly influence iron status.
