When a doctor tells you or your child that you have a blood disorder called Beta Thalassemia, it's important to know exactly what type you have. Because the type of disease you have will determine the symptoms and treatment you need. You may be a little scared when you hear this name. But don't worry, we'll explain everything clearly and simply.
Simply put, what is beta thalassemia?
Beta thalassemia is a genetic disease that affects our blood. Okay, now let's see how this happens inside the body.
Inside the red blood cells in our blood is a special protein called hemoglobin . This is the vehicle that takes oxygen from the lungs and distributes it to the cells throughout the body. It's like an oxygen delivery service. In a person with beta thalassemia, this hemoglobin protein is not produced as much as it needs. The reason for this is a change, or mutation, in a gene related to hemoglobin production (HBB gene).
When hemoglobin decreases, the body's cells do not receive the required amount of oxygen. This is why various symptoms appear. There are three main types of this disease. Let's look at each of them separately.
1. Transfusion-dependent Beta Thalassemia
This is also called Thalassemia Major . This is the most severe form of thalassemia. This condition occurs only if a child inherits two mutated copies of the gene for the disease from both parents.
A child with this condition is usually diagnosed before the age of two .
As parents, we know that it can be very difficult to cope with the news that your little one has a serious illness. It is normal to feel overwhelmed and worried. Don't be alone at this time. Talk to your family and friends about this. Their support will be a great source of strength. Also, if you feel overwhelmed and worried, ask your doctor to refer you to a mental health counselor. It is nothing to be ashamed of, and it is important to stay strong for your child.
What are the symptoms that can be seen in this situation?
- Severe anemia: Due to very low hemoglobin, the child feels tired and exhausted all the time. They may appear pale.
- Stunted growth: The baby's growth is very slow compared to other children.
- Enlargement of the spleen and liver: As a large number of damaged red blood cells accumulate in the spleen and liver, these organs gradually enlarge over time.
- Weakening of bones: As the bone marrow has to make more red blood cells, the bone marrow can swell and the bones can become thin and brittle.
- Delayed puberty: As you age, puberty can be delayed due to the effects on hormonal function.
- The risk of diabetes and blood clots may also increase in adulthood.
Treatment methods
To control this severe anemia, regular blood transfusions are essential. However, when you continue to give blood, the amount of iron in the body can increase unnecessarily. This extra iron can damage the liver, heart, and endocrine system.
To prevent this, a treatment called Iron Chelation Therapy is used. Simply put, this removes the excess iron that has accumulated in the body. There are medications that are given for this.
2. Nontransfusion-dependent Beta Thalassemia
This is also called Thalassemia Intermedia . The symptoms of this are not as severe as those of the previously mentioned Thalassemia Major.
Typically, a person with this condition sees a doctor because of problems such as constant fatigue, yellowing of the skin (jaundice), or failure to thrive.
Symptoms that can be seen in this condition
- Enlargement of the spleen.
- Delayed puberty.
- Weakened bones and the risk of breaking easily.
- Fatigue caused by anemia.
Because the symptoms of this condition are not so severe, regular blood transfusions are often not necessary . You may not need to give blood for the rest of your life. But that is up to your doctor to decide.
3. Beta Thalassemia Minor
This is also called "Thalassemia Trait." In our country, many people call this condition "being a Thalassemia carrier."
This is the mildest form of thalassemia. A person with this condition may not have any symptoms other than mild anemia . Many people live for years without even knowing they have the condition. It is sometimes discovered incidentally when a blood test is done for another condition.
This condition usually does not require regular treatment unless you feel tired or exhausted.
But even if you don't have symptoms, it's important to know that you are a carrier of Thalassemia Trait. Especially if you're getting married or planning to have a child. Because if your partner is also a carrier of Thalassemia Trait, there's a 1 in 4 (25%) risk that your child will have Thalassemia Major, a serious condition. That's why it's important to talk to your doctor about this and get tested.
| Thalassemia type | Seriousness | Main symptoms and treatment |
|---|---|---|
| Thalassemia Major | Very serious | Severe anemia, stunted growth. Regular blood transfusions and iron chelation therapy are essential. |
| Thalassemia intermedia | Moderately serious | Moderate anemia, fatigue. Often no need for regular blood transfusions. |
| Thalassemia minor (Minor/Trait) | Not serious (carrier status) | Often there are no symptoms. No treatment is needed. But awareness is essential in family planning. |
Take-Home Message
- Beta thalassemia is a hereditary condition that reduces hemoglobin production.
- There are three main types of this: major (severe), intermedia (moderate), and minor (mild/moderate).
- Thalassemia major requires regular blood transfusions and iron-removal therapy.
- If you have thalassemia minor (a carrier), you may not have symptoms. However, knowing whether your partner is also a carrier is very important if you are expecting a healthy baby.
- Don't be shy or afraid to talk openly with your doctor about the type of thalassemia you have, its treatment, and any questions you may have.
