What is Anaemia? Exploring the Spectrum of Anaemia

Anaemia is a medical condition that affects millions of people worldwide. It occurs when the number of red blood cells in the body is low, or the red blood cells are not functioning correctly. This condition can lead to various health complications and can significantly impact a person's quality of life. In this blog post, we will explore what anaemia is, its symptoms, causes, and treatment options available.

What is Anaemia?

Anaemia is a medical condition that occurs when the body has a low number of red blood cells or a decreased amount of haemoglobin in the red blood cells. Haemoglobin is the protein in red blood cells that carries oxygen throughout the body. When there is a lack of haemoglobin or red blood cells, the body does not receive enough oxygen, and this can cause a range of symptoms.

Exploring the Spectrum of Anaemia

Anaemia, characterized by a lack of red blood cells or hemoglobin, comes in many forms, each with unique causes and presentations. Let's delve into some of the most common types and their brief summaries:

1. Iron-deficiency anaemia

    • Cause: Lack of iron, often due to inadequate intake, blood loss, or pregnancy.
    • Symptoms: Fatigue, weakness, pale skin, dizziness, and shortness of breath.
    • Treatment: Iron supplements and dietary changes.

2. Vitamin B12 and folate deficiency anaemia

    • Cause: Insufficient intake of vitamin B12 or folate, affecting red blood cell production.
    • Symptoms: Fatigue, weakness, numbness, tingling, and digestive problems.
    • Treatment: Vitamin B12 or folate supplements, dietary modification.

3. Aplastic anaemia

    • Cause: Bone marrow dysfunction leading to insufficient red blood cell production.
    • Symptoms: Fatigue, paleness, frequent infections, and bleeding.
    • Treatment: Depending on severity, medications, blood transfusions, or stem cell transplant.

4. Hemolytic anaemia

    • Cause: Abnormal breakdown or destruction of red blood cells.
    • Symptoms: Fatigue, jaundice, dark urine, and enlarged spleen.
    • Treatment: Addressing the underlying cause, medications, and in some cases, spleen removal.

5. Sickle cell anaemia

    • Cause: Inherited genetic condition affecting hemoglobin structure, leading to red blood cell deformation and destruction.
    • Symptoms: Painful episodes (crises), fatigue, jaundice, and delayed growth.
    • Treatment: Pain management, medications, hydroxyurea, and in severe cases, blood transfusions or bone marrow transplant.

6. Thalassaemia

    • Cause: Inherited genetic mutations affecting hemoglobin production.
    • Symptoms: Vary depending on the severity, ranging from mild anaemia to fatigue, paleness, and bone deformities.
    • Treatment: Blood transfusions, iron chelation therapy, and in severe cases, bone marrow transplant.

7. Megaloblastic anaemia

    • Cause: Vitamin B12 or folate deficiency affecting DNA synthesis in red blood cell production, resulting in large, immature red blood cells.
    • Symptoms: Similar to vitamin B12 and folate deficiency anaemia, but often with neurological symptoms like memory problems and numbness.
    • Treatment: Vitamin B12 or folate supplements, dietary modification.

Symptoms of Anaemia

The symptoms of anaemia can vary depending on the severity and underlying cause of the condition. Some common symptoms include:

  1. Fatigue and weakness: A lack of oxygen in the body can cause a person to feel tired and weak, even after getting enough sleep.
  2. Shortness of breath: If the body is not receiving enough oxygen, a person may feel short of breath, even after light activity.
  3. Dizziness and headaches: A lack of oxygen can cause dizziness and headaches, especially when standing up or exerting energy.
  4. Pale skin: A person with anaemia may have pale skin due to a lack of red blood cells.
  5. Irregular heartbeat: A person with anaemia may experience an irregular heartbeat, palpitations, or chest pain.
  6. Cold hands and feet: Anaemia can cause poor circulation, leading to cold hands and feet.

Causes of Anaemia

There are several types of anaemia, and the causes can vary depending on the type of anaemia a person has. Some common causes include:

  1. Iron deficiency anaemia: The most common type of anaemia is caused by a lack of iron in the body. This can occur due to a poor diet or an inability to absorb iron from food.
  2. Vitamin deficiency anaemia: A lack of vitamin B12 or folate in the body can lead to anaemia. This can occur due to a poor diet or an inability to absorb these vitamins from food.
  3. Chronic disease anaemia: Certain chronic diseases, such as kidney disease or cancer, can lead to anaemia.
  4. Haemolytic anaemia: This type of anaemia occurs when red blood cells are destroyed faster than they can be produced. This can occur due to an autoimmune disorder or certain medications.

What is Fanconi Anemia?

Fanconi anemia (FA) is a rare genetic disorder that affects the bone marrow and its ability to produce blood cells. Some key facts about Fanconi anemia include:

  • It is an inherited disorder caused by mutations in any of at least 22 different genes. The genes involved play important roles in DNA repair.
  • People with FA have a higher than normal risk of bone marrow failure (aplastic anemia), leukaemia, and certain solid tumours. Bone marrow failure is the most common cause of death.
  • Major signs and symptoms include short stature, skeletal abnormalities, increased skin pigmentation, small head size (microcephaly), and developmental or intellectual disabilities in some cases.
  • The main blood abnormalities are low blood cell counts (pancytopenia) due to bone marrow problems making too few red blood cells, white blood cells and platelets. This can lead to fatigue, easy bruising and bleeding, and increased infections.
  • The gold standard diagnostic test involves testing chromosomes to check for increased breakages when cells are exposed to certain chemicals. Other cell or DNA tests may also assist diagnosis.
  • Treatment focuses on bone marrow transplant to prevent bone marrow failure, regular blood counts monitoring, cancer surveillance, and symptom management. Gene therapy research is also ongoing.

Fanconi anemia is a complex-inherited disorder affecting the bone marrow's ability to function properly. Early diagnosis and careful management of symptoms and complications are important.

Treatment of Anaemia

The treatment for anaemia will depend on the underlying cause of the condition. Some common treatments include:

  1. Iron supplements: For iron deficiency anaemia, iron supplements may be prescribed to increase the amount of iron in the body.
  2. Vitamin supplements: For vitamin deficiency anaemia, vitamin B12 or folate supplements may be prescribed.
  3. Blood transfusions: In severe cases of anaemia, a blood transfusion may be necessary to replace the red blood cells in the body.
  4. Treat underlying conditions: If anaemia is caused by a chronic disease, treating the underlying condition may help improve symptoms of anaemia.

Prevention of Anaemia

There are several steps a person can take to prevent anaemia, including:

  1. Eating a balanced diet: Consuming a diet rich in iron, vitamin B12, and folate can help prevent anaemia.
  2. Taking supplements: For individuals at risk of anaemia, taking iron or vitamin supplements can help prevent the condition.
  3. Treating underlying conditions: If an underlying condition is causing anaemia, treating that condition can help prevent anaemia from developing.
  4. Regular health check-ups: Regular health check-ups can help detect and treat any underlying health conditions that may lead to anaemia.

How to Test for Anaemia?

If you are experiencing symptoms of anaemia, your doctor may recommend a blood test to diagnose the condition. There are several types of blood tests that can be performed to determine whether a person has anaemia and what type of anaemia they have. In this section, we will explore some blood tests used to diagnose and monitor anaemia.

Complete Blood Count (CBC)

A complete blood count (CBC) is a common blood test used to diagnose anaemia. The CBC measures many components of the blood, including the number of red blood cells, white blood cells, and platelets. If a person has a low number of red blood cells or a low level of haemoglobin in their red blood cells, this can indicate anaemia.

Haemoglobin Electrophoresis

Haemoglobin electrophoresis is a blood test that can help diagnose certain types of anaemia, such as sickle cell anaemia or thalassemia. This test measures the different types of haemoglobin in the blood and can detect abnormal haemoglobin that may be causing the anaemia.

Iron Studies

Iron studies are blood tests used to diagnose iron deficiency anaemia. These tests measure the levels of iron, ferritin, and transferrin in the blood. Low levels of iron and ferritin and high levels of transferrin can indicate iron deficiency anaemia.

Vitamin B12 and Folate Tests

Blood tests can also measure the levels of vitamin B12 and folate in the blood. Low levels of these vitamins can lead to vitamin deficiency anaemia.

Other Tests

In some cases, additional tests may be needed to diagnose anaemia or determine the underlying cause. These tests may include a bone marrow biopsy, which involves taking a sample of bone marrow from the hip bone, or a reticulocyte count, which measures the number of young red blood cells in the blood.

Monitoring Anaemia

If you are diagnosed with anaemia, your doctor may recommend regular blood tests to monitor your condition. These tests can help determine whether your treatment is working and whether your haemoglobin levels are improving. Depending on the type of anaemia you have, your doctor may recommend blood tests every few weeks or every few months.


Anaemia is a common blood disorder that affects millions of people worldwide. It can cause a range of symptoms, including fatigue, weakness, shortness of breath, and pale skin. There are several types of anaemia, and the causes can vary depending on the type of anaemia a person has. Treatment options for anaemia depend on the underlying cause, and may include iron or vitamin supplements, blood transfusions, or treating underlying conditions. By following preventative measures, such as consuming a balanced diet and regular health check-ups, individuals can reduce their risk of developing anaemia. If you are experiencing symptoms of anaemia, it is important to seek medical attention and receive a proper diagnosis and treatment plan.
