Certain disorders or surgeries that affect the intestines can also interfere with how your body absorbs iron. Even if you get enough iron in your diet, celiac disease or intestinal surgery such as gastric bypass may limit the amount of iron your body can absorb. If a woman has endometriosis she may have heavy blood loss that she can not see because it is hidden in the abdominal or pelvic area.
Anemia is a common condition and can occur in both men and women of any age and from any ethnic group. Some people may be at greater risk of iron deficiency anemia than others, including:. A complete blood count CBC is usually the first test a doctor will use. A CBC measures the amount of all components in the blood, including:. The CBC provides information about your blood that is helpful in diagnosing iron deficiency anemia.
This information includes:. A normal hematocrit range is The normal hemoglobin range is In iron deficiency anemia, the hematocrit and hemoglobin levels are low. Also, RBCs are usually smaller in size than normal.
A CBC test is often performed as part of a routine physical examination. It may also be performed routinely before a surgery. Anemia can usually be confirmed with a CBC test. Your doctor might order additional blood tests to determine how severe your anemia is and help determine treatments. They may also examine your blood through a microscope.
These blood tests will provide information, including:. Ferritin is a protein that helps with iron storage in your body. Low levels of ferritin indicate low iron storage. Transferrin is a protein that transports iron. Certain at-home test kits can check iron levels as well as being able to check ferritin levels and TIBC.

One test you may have is fecal occult test to look for blood in your feces. Iron deficiency in patients with heart failure impairs the quality of life, irrespective of the presence of anemia. Notably patients with inflammation or clinically significantly impaired liver or renal function were excluded from the trial The patients have often received a spectrum of diagnoses, such as subclinical hypothyroidism treated with levothyroxine alone or with T3 containing preparations , chronic fatigue syndrome, fibromyalgia, chronic Lyme disease, burnout, and overtraining.
The blood count has usually been normal. Here are two examples. Patient 1. At the first visit, 3 months after start of treatment, the patient was still taking prednisolone 10 mg daily. At the same time, she reported muscle and joints pains already few years back and restless legs occasional use of pramipexole 0. Her menopause had occurred 6 years earlier, but her menstruation had always been scarce and she had never donated blood or been pregnant. The patient was considered iron deficient for reasons unknown.
Ferrous sulfate mg daily was prescribed. The iron supplementation was continued for another 4 months and then discontinued. Gradually the patient reported reappearance of restless legs and fatigue. Then full blood count and ferritin were determined and the iron supplementation was reinitiated. The same took place when the iron was again withdrawn without any change in the full blood count.
She had had two normal pregnancies and deliveries 10 and 7 years earlier with a history of anemia during pregnancies. The patient was referred because of intractable fatigue and sleep disturbances waking up several times during the night for 6 years. Sleep apnea was excluded by polysomnography. The thyroid hormone had induced chemical euthyroidism and had relieved her fatigue slightly.
The ferritin concentration was only 5. Oral iron was prescribed with increasing doses and from month 7—14 the patient took ferrous sulfate mg three times daily with apparently good compliance. Iron ferric carboxymaltose, mg was infused i. The patient has no knowledge of the laboratory results at the time, when she reported the reappearance of the symptoms.
Iron deficiency is a common clinical challenge 2 , 3 , 4 , but the diagnosis is difficult when blood count is normal. Even if ferritin is the most sensitive method to detect iron deficiency 2 , 3 it may be difficult to determine which ferritin concentration is indicating iron deficiency 5 , 6. Furthermore, the diagnosis is supported by the ferritin determination and exclusion of other causes of symptoms 16 , Hypothyroidism based on symptoms is indistinguishable from iron deficiency 18 , Fatigue and neurocognitive symptoms often raise a suspicion of depression.
Furthermore, headache and muscle and joint pain associated with iron deficiency are repeatedly considered migraine and fibromyalgia syndrome, respectively 3 , The multitude of symptoms is commonly associated low ferritin concentration without anemia 1 , 17 , 20 , 21 , In addition, iron supplementation has been shown to improve fatigue and physical performance with low ferritin concentration 23 , 24 , The symptoms of iron deficiency may arise from the metabolic system where many of the proteins are iron containing 2 , 3 , 11 , 12 , The conclusion is that the supply of iron to these systems may also explain the fluctuation of symptoms as described in the cases.
Furthermore, there may a question of iron deficiency in combination with functional iron deficiency, where there is an insufficient mobilization of erythroid iron in the presence of increased requests 2 , 3 , 5.
