World Thalassemia Awareness Day: Advocating for Thalassemia Awareness and Support

What is Thalassemia?

Thalassemia is an inherited blood disorder characterized by insufficient production of hemoglobin, a crucial protein in red blood cells. Hemoglobin plays a vital role in carrying oxygen throughout the body. When there’s an inadequate amount of hemoglobin, red blood cells don’t function effectively and have a shorter lifespan, resulting in fewer healthy cells circulating in the bloodstream.

The primary function of red blood cells is to transport oxygen to all cells in the body. Oxygen serves as a vital nutrient for cellular function. With a deficiency in healthy red blood cells, oxygen delivery to cells is compromised, leading to symptoms such as fatigue, weakness, and shortness of breath—a condition known as anemia. The severity of anemia in individuals with thalassemia can vary from mild to severe. Severe anemia has the potential to cause organ damage and may even be life-threatening.

Types of Thalassemia:

Hemoglobin, responsible for transporting oxygen to cells, consists of two distinct components: alpha and beta. The terms “alpha” or “beta” thalassemia denote the specific part of hemoglobin that is inadequately produced. In cases where either the alpha or beta component is deficient, there is an insufficient supply of the necessary building blocks to produce normal levels of hemoglobin.


Due to the reduced number of red blood cells in thalassemia, individuals may exhibit symptoms of anemia, which include feelings of tiredness or weakness. Other possible symptoms may include:

  • Dizziness
  • Shortness of breath
  • Rapid heart rate
  • Headaches
  • Leg cramps
  • Difficulty concentrating
  • Pale skin

In response to the low red blood cell count, the body intensifies its efforts to produce more red blood cells. The bone marrow, situated within the central, spongy portion of bones, becomes more active. Consequently, the bone marrow may enlarge, leading to bone expansion and potential thinning, rendering bones more susceptible to fractures.

Additionally, the spleen, located on the left side of the abdomen beneath the lower ribs, serves as another site for blood cell production. Apart from its blood-filtering function, the spleen also monitors for infections and initiates the immune response against them. In individuals with thalassemia, the spleen may enlarge as it attempts to compensate for decreased red blood cell production. However, this heightened activity may compromise the spleen’s ability to effectively filter blood and combat infections. Consequently, individuals with thalassemia are considered “immunocompromised,” meaning their immune defenses are weakened. As a result, they may be more susceptible to infections and may require additional protective measures, such as flu shots and vaccinations.

Treatment Options for Thalassemia:

The treatment approach for thalassemia varies based on the severity of the condition. The severity of thalassemia correlates with the amount of hemoglobin present in the body, consequently affecting the severity of anemia.

One method to address anemia involves replenishing the body’s red blood cell supply to enhance oxygen transport. This is typically achieved through blood transfusions, a routine and safe procedure where blood is administered via a small plastic tube inserted into a blood vessel. Individuals with severe thalassemia, particularly thalassemia major, often require regular blood transfusions due to their low hemoglobin levels. Those with thalassemia intermedia, a condition less severe than major but more severe than trait, may occasionally require blood transfusions, especially during periods of infection or illness. Conversely, individuals with thalassemia minor or trait typically do not require blood transfusions, as they either do not experience anemia or have only mild symptoms.

Additionally, individuals with thalassemia may be prescribed supplemental B vitamins, such as folic acid, to aid in the treatment of anemia. Folic acid supplementation supports the development of red blood cells and is often administered alongside other therapeutic interventions.

Importance of Genetic Counseling in Living with Thalassemia:

Genetic counseling in thalassemia is essential for:

  1. Understanding Inheritance: Clarifying how thalassemia is inherited and helping families make informed decisions about family planning.
  2. Risk Assessment: Evaluating the risk of passing thalassemia to future generations based on family history and genetic testing.
  3. Prenatal Testing: Offering testing options for couples planning pregnancies to assess the risk of having a child with thalassemia.
  4. Education and Support: Providing information, emotional support, and resources for individuals and families affected by thalassemia.
  5. Advocacy and Resources: Connecting individuals with support groups, advocacy organizations, and medical resources for managing thalassemia effectively.

BNI’s Message on World Thalassemia Day:

Let’s join hands to spread awareness about thalassemia. Together, we can make a difference by educating others, supporting affected individuals and families, and advocating for better care and research. Every action, big or small, contributes to a brighter future for those living with thalassemia. Together, let’s create a world where everyone has the knowledge, support, and resources they need to thrive.
