Thalassaemia Symptoms

Quick Glance: Common Thalassaemia Symptoms

The common symptoms of thalassaemia are:

• Persistent tiredness, fatigue, and low energy levels

• Pale skin due to reduced haemoglobin levels

• Yellowing of the skin and eyes (jaundice)

• Shortness of breath, especially during physical activity

• Rapid heartbeat or palpitations

• Enlarged abdomen due to an enlarged spleen or liver

• Slow growth and delayed development in children

• Delayed puberty in older children and teenagers

Symptoms may not appear in people with thalassaemia traits, as they may have normal health or only mild anaemia. When symptoms do occur, their severity of symptoms depends on the type of thalassaemia inherited and its effect on haemoglobin production.

Thalassaemia Symptoms That Should Not Be Ignored

Certain symptoms may indicate significant anaemia or complications related to severe thalassaemia. Some symptoms that may require medical assessment include:

Why Do Thalassaemia Symptoms Occur?

Thalassaemia symptoms occur because inherited changes in certain genes affect the body’s ability to produce normal haemoglobin. This important protein, found inside red blood cells, carries oxygen from the lungs to different parts of the body. When the body does not produce enough healthy haemoglobin, red blood cells become smaller, weaker, and may break down more quickly.

This faster reduction in red blood cell count leads to anaemia. People generally start experiencing symptoms such as fatigue, weakness, pale skin, and shortness of breath. The body may try to compensate by making more red blood cells, increasing the workload of the bone marrow.

In severe forms of thalassaemia, increased bone marrow activity can affect normal bone development and may lead to changes in the facial and skull bones. The spleen and liver may also become enlarged because these organs help remove damaged red blood cells from circulation.

Another effect of red blood cell breakdown is the production of bilirubin, a yellow pigment formed from haemoglobin. When bilirubin builds up in the blood, it can cause jaundice, leading to yellowing of the skin and eyes.

Thalassaemia Symptoms That Require Immediate Medical Attention

Thalassaemia is a long-term condition, but some symptoms can signal complications that need prompt medical attention. This is especially important for people with severe thalassaemia or those who receive regular blood transfusions.

Seek immediate medical care if you have thalassaemia and experience:

• Severe difficulty breathing or sudden worsening of breathlessness

• Chest pain, irregular heartbeat, or severe palpitations

• Fainting, loss of consciousness, or extreme weakness

• High fever, especially in people who have had their spleen removed

• Sudden severe abdominal pain or swelling

• Signs of severe anaemia, such as extreme paleness with a rapid heartbeat

• Symptoms suggesting heart problems due to iron overload

These symptoms may indicate complications such as severe anaemia, infection, or organ strain from iron accumulation.

Symptoms of Thalassaemia Based on Type

Thalassaemia has different types depending on the genetic changes involved and the severity of haemoglobin production problems. The table below explains the common symptoms associated with different types of thalassaemia:

Symptoms of Thalassaemia in Children

Severe forms of thalassaemia often become noticeable during infancy or early childhood. Since children are still growing, low haemoglobin levels may have long-term effects on their physical development.

Common symptoms of thalassaemia in children include:

• Pale skin, tiredness, and low energy levels

• Irritability or reduced activity levels

• Poor appetite and slow growth

• Enlarged abdomen due to an enlarged spleen or liver

• Yellowing of the skin and eyes

• Changes in facial bone development in severe, untreated cases

• Delayed puberty during the teenage years

• Increased risk of infections in some children

Early evaluation is important when children show signs of persistent anaemia or delayed growth, as these symptoms can have several possible causes and require proper medical assessment.

Can You Have Thalassaemia Without Symptoms?

Yes, it is possible to have thalassaemia without noticeable symptoms. People with thalassaemia trait usually produce enough haemoglobin to remain healthy and may only have mild changes in their blood test results.

Many people discover they have thalassaemia trait during routine health checks, blood tests before marriage, pregnancy planning, or when investigating mild anaemia. Since thalassaemia trait and iron deficiency anaemia can appear similar in some blood tests, additional testing may be needed to identify the correct cause.

Being a carrier does not usually cause serious health problems, but it is important for family planning. If both parents carry certain thalassaemia genes, their child may have a higher chance of inheriting a more severe form of the condition.

When Can Thalassaemia Symptoms Become Life-Threatening?

Severe thalassaemia can lead to serious complications if it is not monitored and managed properly. Some of the life-threatening thalassaemia complications are given below:

How are Thalassaemia Symptoms Diagnosed?

Doctors use different blood tests and genetic investigations to confirm thalassaemia and identify its type. Take a look at the diagnostic tests commonly used and their purpose:
