Thalassemia is a type of blood disorders that are genetic in origin. This condition affects the body’s ability to produce normal, healthy red blood cells. As a consequence, the RBCs cannot supply enough hemoglobin to the body and hence there is a less supply of oxygen too. As a result, the cells start getting damaged and cannot function properly, leading to anemia and fatigue.

Is Thalassemia Minor A Fatal Problem?

Those suffering from thalassemia minor or trait thalassemia usually do not show any symptoms and they lead a normal life as those who are unaffected. Thalassemia minor is not a fatal condition. Other types of thalassemia may create moderate to severe symptoms depending upon the type.

RBCs perform an important function of carrying oxygen to all the cells in our body. The cells use this oxygen as food to function properly. If there won’t be enough RBCs in the body, there also won’t be proper oxygen supply to the cells in our body. This may cause various symptoms like tiredness, breathlessness, fatigue in the body. This condition is known as anemia. Those suffering from thalassemia may get anemia, which can be mild or severe in nature. Severe anemia can damage the organs, cause organ failure or even lead to death.

Signs and symptoms of thalassemia-

  • Tiredness or fatigue
  • Weakness
  • Yellowish and pale skin and eyes
  • Slow growth
  • Dark colored urine
  • Bone deformities especially of the face

The signs and symptoms of thalassemia vary according to the type of the disease. Some types present with mild symptoms while other types present with more severe symptoms.

Types of Thalassemia

Thalassemia can be categorized in two different ways. One classification is based upon the part of the hemoglobin that is affected- alpha or beta; while the other is based upon the severity of the thalassemia.

Alpha thalassemia-

The alpha part of the hemoglobin is made up of four genes-two from each parent. Defect in one or more than one gene can cause the disease. The condition is then classified into different types. Let us have a look at them.

1 mutated gene-

Results in a silent carrier form of the disease

This type does not show any symptoms usually

This type is also known as alpha thalassemia minima

2 mutated genes-

Results in trait form of the disease

Symptoms are mild

This type is also known as alpha thalassemia minor

3 mutated genes-

This results in hemoglobin H type of the disease

The symptoms in this type are moderate

This type is also known as hemoglobin H disease.

4 mutated genes-

This is a rare form of the disease

This results in major form of the disease

The symptoms of this type are usually very severe and fatal

This is also known as Hydrops fetalis with hemoglobin Barts

Beta thalassemia-

The beta part of the hemoglobin is made up of two genes- one from each parent. Defect in one or more than one gene can be responsible for causing the disease. They are then classified accordingly. Let us have a look at the different types of beta thalassemia.

1 mutated gene-

This results in a mild form of the disease

The symptoms are usually mild

This type is also known as the thalassemia minor or beta-thalassemia

2 mutated genes-

This results in moderate to severe form of the disease

The symptoms are usually moderate to severe

This type is also known as thalassemia major or Cooley anemia

Thalassemia intermedia, a milder form can also be a result of 2 mutated genes.

Conclusion

Thalassemia is an inherited blood disorder. It has many types depending upon the part of the hemoglobin affected and severity of the disease. Thalassemia minor is not a fatal problem and usually does not present with any signs and symptoms. Those suffering from thalassemia minor can lead an almost normal life.
