Anaemia in Children: Signs, Causes, and Treatment

Anaemia is an important health concern because it can affect various aspects of a person's life, including physical and cognitive performance. It can also impact the immune system and make individuals more susceptible to infections. Anaemia is a significant public health problem in India, especially among children. According to recent studies, more than 60% of children under five years old in India are affected by anaemia. In this blog, we will explore the causes, symptoms and signs of anaemia to give a better understanding of the treatment of anaemia.

Anaemia is a condition in which the body lacks enough healthy red blood cells or haemoglobin to carry adequate oxygen to the tissues.

1. Role of Red Blood Cells

Red blood cells are produced in the bone marrow and contain haemoglobin, which binds to oxygen. As they travel through the body, red blood cells deliver oxygen to tissues and remove carbon dioxide. Haemoglobin plays a crucial role in carrying oxygen from the lungs to all parts of the body.

2. Common Types of Anemia Found in Children

The following are the anaemia types commonly found in children:

• Iron-deficiency Anaemia: This anaemia type arises when iron is deficient in the body. It is one of the most common types of anaemia in children, usually caused by poor dietary intake or decreased iron absorption.
• Vitamin-deficiency Anaemia: When there is a deficiency of certain vitamins like vitamin B12 or folate, it can result in anaemia. These vitamins are essential for red blood cell production and their deficiency affects their proper development.
• Genetic or Inherited Anaemia: Certain genetic conditions like thalassaemia or sickle cell disease can cause anaemia in children. These conditions affect the structure or production of red blood cells, leading to a reduced lifespan of these cells.

It's important to recognize anaemia indications early, as anaemia can affect a child's growth, development, and overall health. If your child exhibits any of these anaemia symptoms, consult a doctor for further evaluation and guidance on managing anaemia.

1. Physical Anemia Symptoms to Look Out For

Some physical symptoms of anaemia are:

• Pale skin, lips, and nail beds
• Fatigue or lack of energy
• Shortness of breath or rapid heartbeat
• Weakness or dizziness

2. Behavioural Signs of Anaemia

Behavioural signs of anaemia are:

• Irritability or mood swings
• Poor appetite
• Cravings for non-food items like ice, dirt, or paper
• Difficulty concentrating or learning problems

Common causes of anaemia in children in India include:

1. Nutritional Factors

Nutritional deficiencies can be a major factor for anaemia:

• Lack of Iron-rich Foods: Iron is an essential mineral for the production of healthy red blood cells. When children don't consume enough iron-rich foods, it can lead to anaemia.
• Vitamin Deficiency: Vitamins like B12 and folate are essential for the production of healthy red blood cells. If children have a  deficiency in these vitamins, it can result in anaemia.

2. Infectious Diseases and Parasitic Infections

Certain infectious diseases and parasitic infections can contribute to anaemia in children. Malaria, a mosquito-borne disease prevalent in India, destroys red blood cells. Hookworms, common in areas with poor sanitation, feed on blood and nutrients in the intestines, leading to anaemia.

Preventive measures such as mosquito nets and deworming treatments can help reduce the risk of anaemia caused by these infections.

3. Genetic Factors

Conditions like sickle cell disease and thalassaemia affect the structure or production of red blood cells, leading to a reduced lifespan of these cells and subsequently causing anaemia.

Genetic counselling and prenatal testing can help identify these conditions early on and provide appropriate management options.

Seeking medical attention is important if you experience anemia symptoms. Early diagnosis is essential to determine the underlying cause and develop an appropriate treatment plan. The following diagnostic tests are commonly used to detect anaemia in children:

1. Complete Blood Count (CBC)

Complete Blood Count test measures various components of your blood, including red blood cells, white blood cells, and platelets. It provides valuable information about the size, shape, and quantity of red blood cells, helping identify different types of anemia.

2. Iron studies

Iron studies  measure the levels of iron in your body, including serum ferritin (a protein that stores iron) and transferrin saturation (the percentage of iron-binding sites on transferrin that are occupied by iron).

3. Vitamin Level Testing

Deficiencies in vitamins like B12 and folate can cause certain anaemia types. Testing the  levels of these vitamins helps diagnose the underlying cause accurately.

4. Genetic Testing

In some cases, anaemia may be due to inherited conditions like sickle cell disease or thalassaemia. Genetic testing can identify specific gene mutations responsible for these conditions, aiding in diagnosis and genetic counselling.
 

The treatment for anaemia depends on the underlying cause and severity of the condition. Here are some common treatment options for anaemia:

1. Dietary Changes

A balanced diet plays an important role in preventing and treating anaemia in children. It is essential to include iron-rich foods in their meals to boost their iron levels. Some recommended iron-rich foods for children include:

• Lean meats
• Eggs
• Fortified cereals
• Dark green leafy vegetables like spinach
• Legumes such as lentils and beans

These foods are packed with essential vitamins and minerals that can help increase the production of red blood cells and improve overall health.

2. Iron and Vitamin Supplements

In some cases, dietary changes alone may not be sufficient to address anaemia.Iron and vitamin supplements  can be prescribed by a doctor to help raise iron levels in the body. The appropriate dosage and administration guidelines vary depending on the severity of anaemia and the individual's age and overall health.Supplements are available in different forms such as:

• Liquid
• Chewable tablets
• Capsules

It is, however, important to follow the prescribed dosage and consult a doctor before starting any supplements.

3. Blood Transfusions

In severe cases or when other anaemia treatment options prove ineffective, blood transfusions may be necessary. Blood transfusions involve receiving healthy blood from a compatible donor to increase the number of red blood cells in the body.

Lifestyle modifications can complement medical treatment for anaemia, improve overall well-being, and help manage the condition effectively.

1. Educating Parents and Caregivers

It is important to educate parents and caregivers about the significance of adherence to treatment plans for managing anaemia. By understanding the importance of compliance, they can ensure that the prescribed treatment, including medications and dietary modifications, is followed diligently.

Educating them about the signs of anemia will also help them recognise the symptoms and take appropriate action promptly.

2. Strategies to Improve Iron Absorption

You can follow the following strategies to improve iron absorption and maximise nutrient intake:

• Pair iron-rich foods with vitamin C-rich sources like citrus fruits to boost iron absorption.
• Avoid tea or coffee during meals, as they inhibit iron absorption.
• Incorporate other nutrients like  vitamin B12 and folate through foods or supplements to improve overall nutrient intake.

3. Healthy Sleep Patterns and Stress Management

Maintaining healthy sleep patterns and managing stress play a vital role in supporting anaemia treatment. Lack of sleep can negatively impact the immune system and overall health, leading to decreased energy levels. Encouraging a consistent sleep routine by establishing regular bedtimes and creating a conducive sleep environment can promote better quality sleep.

Additionally, stress management techniques like meditation, deep breathing exercises, or engaging in hobbies can help alleviate stress levels and enhance overall well-being.

Preventing anaemia in children requires a multifaceted approach. Some strategies include:

1. Encourage Breastfeeding

Breastfeeding plays a vital role in preventing anaemia in infants. Breast milk is rich in iron, which is readily absorbed by the baby's body. Exclusive breastfeeding for the first six months helps provide adequate iron stores, reducing the risk of anaemia. Introducing iron-rich complementary foods after six months is crucial for maintaining iron levels as breast milk alone may not suffice.

2. Immunisations

Diseases like malaria and certain types of bacterial or viral infections can cause haemolysis (destruction of red blood cells), leading to anaemia. Vaccines such as the pneumococcal conjugate vaccine (PCV) and measles vaccine are recommended to prevent these infections.

By ensuring that children receive the appropriate immunisations at the recommended age, the risk of developing anaemia due to these infections can be significantly reduced.

3. Regular Check-ups

Regular check-ups and screenings are essential for the early detection and management of anaemia in children. Early detection allows for timely intervention and appropriate treatment to prevent complications associated with anaemia.
