Iron Deficiency Anemia: Causes, Consequences, and Care

Abstract

Iron deficiency anemia (IDA) is the most prevalent nutritional deficiency globally and a significant public health concern. It is characterized by a reduction in hemoglobin concentration or red blood cell count due to insufficient iron availability, impairing oxygen delivery to tissues. This article outlines the causes, diagnosis, prevention, treatment, and potential complications of untreated IDA.

What is Iron Deficiency and How Does it Affect the Body?

How to Identify Iron Deficiency?

Several methods exist to diagnose iron deficiency and anemia. The most common of these are:

• Transferrin saturation level: This indicator helps assess how effectively iron is being transported throughout the body. A low transferrin saturation level often signals deficiency.
• Complete blood count (CBC): This is the first test used to detect a reduction in hemoglobin or the number of red blood cells. If the results show low levels of these indicators, it may suggest anemia.
• Iron level blood test: This test measures the amount of iron in the blood. In cases of iron deficiency, the iron levels will be low.
• Ferritin: Ferritin is a protein that stores iron in the body. Low ferritin levels in the blood often indicate iron deficiency.
• Transferrin test: Transferrin is a protein that transports iron throughout the body. An elevated transferrin level can indicate iron deficiency.

How to Prevent Iron Deficiency?

Preventing iron deficiency primarily involves proper nutrition and following a few key recommendations:

1. Balanced diet: Include iron-rich foods in your diet. These include meat (especially red meat), fish, eggs, and plant-based sources of iron like legumes, nuts, leafy green vegetables, and whole grains.
2. Consider types of iron: Heme iron from animal products is absorbed more efficiently than non-heme iron from plant sources. To improve iron absorption from plant foods, combine them with vitamin C-rich foods (such as citrus fruits, berries, or bell peppers).
3. Avoid foods that interfere with iron absorption: Some foods, such as coffee, tea, dairy products, and calcium, can reduce iron absorption. It’s best to avoid these foods immediately after eating iron-rich meals.
4. Pregnancy-specific diet: Pregnant women are advised to increase their iron intake due to increased body needs during this period. Doctors may recommend iron supplements.
5. Iron supplements: If you are prone to iron deficiency, your doctor may recommend iron supplements. However, do not start taking supplements without consulting a doctor, as iron overdose can lead to serious consequences.

Complications of Iron Deficiency

If iron deficiency is not detected in time and treated, it can lead to serious complications:

• Increased fatigue and decreased performance: Iron deficiency often causes chronic fatigue, which can reduce the quality of life.
• Cardiovascular diseases: Iron deficiency can lead to hypoxia (oxygen deprivation in tissues), which increases the load on the heart. As a result, heart failure or rapid heartbeat may develop.
• Reduced immune function: Iron is crucial for the proper functioning of the immune system. Its deficiency can weaken the body’s resistance to infections.
• Developmental problems in children: Children with iron deficiency may experience physical and mental developmental issues.

If iron deficiency is confirmed through tests, it is essential to begin treatment. Typically, the treatment consists of two stages: restoring iron levels in the body and preventing recurrences.

Medications

In most cases, iron deficiency is treated with iron supplements. These are usually available in tablet or capsule form, containing iron in the form of sulfate, gluconate, or fumarate. They are typically taken for several months until iron levels in the body are restored.

• How to take: Iron supplements should be taken on an empty stomach to improve absorption. However, if they cause stomach discomfort, they can be taken after meals.
• Side effects: Iron supplements can cause side effects like nausea, constipation, or diarrhea. In such cases, the doctor may adjust the dose or recommend other forms of supplements.

Intravenous iron injections

If the iron deficiency is severe, or if the patient cannot take oral supplements due to gastrointestinal issues (such as conditions that impair absorption), a doctor may recommend intravenous iron injections. This allows for a rapid increase in iron levels in the body.

Dietary adjustments

In addition to medications, it is essential to include iron-rich foods in your diet. This helps maintain normal iron levels and prevent deficiency in the future. Foods such as meat, liver, fish, eggs, legumes, nuts, green leafy vegetables, grains, and other iron-containing foods should be included in the diet.

Treatment of underlying diseases

If iron deficiency is caused by gastrointestinal diseases (such as ulcers, celiac disease, or inflammatory bowel disease), treatment of the underlying condition is necessary. This will improve iron absorption and prevent further loss.

Risks and Side Effects

Although treatment for iron deficiency is generally safe and effective, it is important to be aware of some risks and side effects:

• Iron and inflammatory processes: Excess iron may exacerbate inflammation and oxidative stress in the body. This is particularly important for people with chronic inflammatory conditions.
• Iron overdose: Excessive iron intake can be harmful. Iron overload can lead to poisoning, especially in children who may accidentally ingest iron-containing tablets. Symptoms of overdose include nausea, vomiting, abdominal pain, and diarrhea. In severe cases, overdose can cause liver or kidney damage.

How to Prevent Recurrence of Iron Deficiency?

After restoring normal iron levels in the body, it is crucial to take measures to prevent recurrence of deficiency. Here are a few recommendations:

• Treatment of chronic conditions: If iron deficiency was caused by a chronic disease (such as gastrointestinal disorders), it is essential to manage that condition with appropriate treatment. This will help prevent new episodes of iron deficiency.
• Regular iron level checks: This is especially important for individuals who have previously suffered from iron deficiency or have chronic conditions that affect its absorption. Regular tests will help detect any deviations early.
• Proper diet: Consistently maintain a balanced diet that includes iron-rich foods. It is important not only to consume foods high in iron but also to ensure their absorption—combine iron-rich foods with vitamin C, and avoid excessive intake of substances that may hinder iron absorption (such as coffee, tea, and dairy products immediately after meals).
• Maintenance therapy: In some cases, a doctor may recommend taking small doses of iron supplements as a preventive measure, especially during periods of increased iron needs (such as during pregnancy or intense physical activity).

CONCLUSION

Iron deficiency is a common and treatable issue that can lead to serious complications if not detected and addressed in time. To prevent deficiency, it is important to monitor your diet, regularly check iron levels in the body, and seek treatment when necessary. Prevention and timely treatment help maintain normal iron levels, improve overall health, and prevent the development of anemia.
