Anemia: Causes, Symptoms, Diagnosis, and Treatment

 

Introduction

Anemia is a frequent blood disorder that impacts millions and millions of people globally. It is caused when there are not enough healthy red blood cells (RBCs) or hemoglobin in the body to supply oxygen to the body's tissues. Therefore, the condition often leads to symptoms of fatigue, weakness and shortness of breath.

This in-depth guide covers anemia in full, including its forms, causes, symptoms, diagnosis, treatments and prevention. By knowing anemia, people can do something about it and prevent this condition from getting out of hand.

 

What is Anemia?

Anemia is a medical condition that results from a lack of any of the components in the blood.

·        Red blood cells (RBCs) -The cells that carry oxygen to the body parts after it is supplied to the lungs.

·        Hemoglobin – The iron rich protein in RBCs that combines with oxygen.

When there is not enough RBCs or hemoglobin, the body, the organs, and the tissues do not get enough oxygen, and this leads to different health issues.

 

Global Prevalence of Anemia

As World Health Organization (WHO) puts it, approximately 1.62 billion individuals worldwide have anemia, and:

·        Pregnant women (41.8)

·        Children aged below five (47.4%)

·        Those women in their reproductive age (30.2%)

It is more prevalent in developing nations because of malnutrition and underutilization of healthcare services.

 

Types of Anemia

Anemia has various types; each type has the varied cause and treatment.

1. Iron-Deficiency Anemia

The most widespread, which is triggered by low intake or absorption of iron. Hemoglobin is manufactured by use of iron.

Causes:

·        Malnutrition (deficiency of food containing iron)

·        Blood loss (menstrual period, ulcers, surgery)

·        Pregnancy (more iron requirements)

2. Vitamin Deficiency Anemia (Megaloblastic Anemia)

It happens when the vitamin B12 or folate (B9), needed to create the RBCs is low.

Causes:

·        Unhealthy eating (deficiency of B12 or folate)

·        Pernicious anemia (autoimmune disorder of the absorption of B12)

·        Digestive problems (celiac disease, Crohn’s disease)

3. Aplastic Anemia

One of the most severe conditions, which is rare, but the bone marrow cannot generate enough RBCs, WBCs, and platelets.

Causes:

·        Autoimmune disorders

·        Chemotherapy/radiation treatment

·        Pesticides, benzene Toxins

4. Hemolytic Anemia

It happens when RBCs are destroyed more rapidly than they can be made.

Causes:

·        Genetic illnesses (sickle cell anemia, thalassemia)

·        Infections (malaria)

·        Autoimmune disorders

5. Anemia of Chronic Disease

Related to chronic diseases including:

·        Kidney disease

·        Cancer

·        HIV/AIDS

·        Rheumatoid arthritis

Such conditions disrupt the production of the RBCs.

 

Symptoms of Anemia

Depending on the severity and type of anemia the symptoms may vary but can include:

·        Tiredness and Low energy levels

·        Yellowish or pale skin

·        Breathlessness

·        Lightheaded or dizziness

·        Cold hands, cold feet

·        Irregular pulse (arrhythmia)

·        Headaches

·        Severe pain in the chest (in rare cases)

 

Severe Anemia Complications

When untreated, anemia may cause:

·        Heart difficulties (swollen heart, heart failure)

·        Problems during pregnancy (birth before time, birth weight)

·        Impaired growth of children

·        Higher chances of infections

 

Causes and Risk Factors of Anemia

Primary Causes

1.     Dietary Deficiencies- Iron, vitamin B12 or folate deficiency.

2.     Chronic Blood Loss - Heavy menstrual periods, ulcers, bleeding of the gastrointestinal tract.

3.     Bone Marrow Disorders – Leukemia, Myelodysplastic syndromes.

4.     Genetic Causes – Sickle cell anemia, thalassemia.

Risk Factors

·        Gender- Women (because of menstruation and pregnancy)

·        Age -Infant, small children, and old adults

·        Chronic Diseases – kidney disease, diabetes, cancer disease.

·        Unhealthy Diet Vegetarians/vegans (limited intake of B12)

·        Genetic anemias Family History

Diagnosis of Anemia

To diagnose anemia doctors, employ a number of tests:

1. Complete Blood Count (CBC)

Measures:

·        Hemoglobin levels (Normal range: 12-16g/dL in women, 13.5-17.5 g/dL in men)

·        Hematocrit (RBCs percentage in blood)

·        RBC and size

2. Peripheral Blood Smear

Studies RBC shape and size on a microscope.

3. Iron Studies

·        Serum ferritin (measures body stored iron)

·        TIBC (total iron-binding capacity) & Serum iron

4. Vitamin B12 and Folate Tests

Detects deficiencies.

5. Bone Marrow Biopsy (for severe cases)

Monitors the functioning of the bone marrow.

 

Treatment Options for Anemia

The kind of anemia and its cause determines treatment.

1. Iron-Deficiency Anemia Treatment

·        Ferrous sulfate, ferrous gluconate Irons supplements

·        Food alterations (red meat, spinach, lentils, enriched cereals)

·        Treating the underlying causes (e.g. cessation of blood loss)

2. Vitamin Deficiency Anemia Treatment

·        B12 injection or vitamin B12 supplements

·        Vitamin B supplements

·        Alterations in nutrition (eggs, milk, leafy vegetables)

3. Aplastic Anemia Treatment

·        Blood transfusions

·        Bone marrow transplant

·        Immunosuppressive therapy

4. Hemolytic Anemia Treatment

·        Autoimmune autoimmune causes Corticosteroids

·        Blood transfusions

·        Splenectomy (in severe cases removal of the spleen)

5. Anemia of Chronic Disease Treatment

·        Managing the underlying cause of the disease

·        Kidney disease EPO (erythropoietin) injection

 

Prevention of Anemia

1. Eat a Balanced Diet

·        Animal food: Red meat, reddish beans, green leafy veggies, nuts.

·        Vitamin C food sources: Oranges, and bell peppers (increases absorption of iron).

·        B12 sources: Eggs, dairy and fortified cereals.

·        Folate food: Lentils, asparagus, avocados.

2. Supplements (if needed)

·        Pregnancy vitamins for pregnant women.

·        Iron supplements (if only ordered).

3. Manage Chronic Conditions

·        Periodic check-up for kidney disease, diabetes etc.

4. Avoid Excessive Blood Loss

·        Treats a heavy menstrual flow.

·        Treat ulcers or bleeding of the stomach.

 

Conclusion

Anemia is a common and mostly avoidable disorder. Knowledge of the causes, symptoms and treatment can enable persons to be in charge of their health. However, when you have fatigue, paleness, or experience dizziness, you should go to a doctor and get diagnosed appropriately.

Anemia is a treatable or even preventable condition with the help of a nutrient-rich diet and the control of underlying conditions, as well as medical consultation in case of need. Be aware, be healthy!

Q4: Is it possible to have adequate iron in the vegetarian diet?
