Childhood Asthma

Overview

Childhood asthma is a medical condition where the lungs and airways become easily inflamed when exposed to certain triggers, such as inhaling pollen or catching a cold or other respiratory infection. Common symptoms in children include wheezing, shortness of breath, and a whistling sound when breathing out. While there is no cure for childhood asthma, proper treatment can help manage symptoms and prevent damage to growing lungs. Triggers can include viral infections, air pollutants, allergies, physical activity, and weather changes. Risk factors for developing childhood asthma include exposure to tobacco smoke, a family history of asthma or allergies, and certain respiratory conditions.

Understanding the disease

Symptoms

The symptoms of childhood asthma include:

1. A whistling or wheezing sound when breathing out.
2. Shortness of breath.
3. Delayed recovery or bronchitis after a respiratory infection.
4. Trouble breathing that hampers play or exercise.
5. Fatigue, which can be due to poor sleep. These symptoms can vary from child to child and may worsen or improve over time. If you suspect your child has asthma, consult a healthcare provider for an early diagnosis and appropriate treatment.

Risk Factors

The risk factors for developing childhood asthma include:

1. Exposure to tobacco smoke, including before birth.
2. Previous allergic reactions, including skin reactions, food allergies, or hay fever (allergic rhinitis).
3. A family history of asthma or allergies.
4. Living in an area with high pollution.
5. Obesity.
6. Respiratory conditions, such as a chronic runny or stuffy nose, inflamed sinuses, or pneumonia.
7. Gastroesophageal reflux disease (GERD).
8. Being male.
9. Being Black or Puerto Rican. By understanding these risk factors and taking preventive measures, you can help reduce the chances of your child developing asthma or help manage the condition effectively.

Development

Childhood asthma develops when the lungs and airways become easily inflamed in response to certain triggers. This can cause symptoms like wheezing, shortness of breath, and coughing, which can interfere with daily activities, school, and sleep. The condition is caused by increased immune system sensitivity, which leads to the swelling of the lungs and airways and the production of mucus when exposed to specific triggers. Triggers vary from child to child and can include viral infections, exposure to air pollutants, allergies to dust mites, pet dander, pollen, or mold, physical activity, weather changes, or cold air. Although asthma cannot be cured, proper treatment and management can help control symptoms and prevent damage to the growing lungs.

Assessment and Diagnosis

Triage

You should see a doctor if you suspect childhood asthma if you notice any of the following symptoms or conditions in your child:

1. Coughing that is constant, intermittent, or seems linked to physical activity.
2. Wheezing or whistling sounds when your child breathes out.
3. Shortness of breath or rapid breathing.
4. Complaints of chest tightness.
5. Repeated episodes of suspected bronchitis or pneumonia.
6. Your child's chest and sides pulling inward when breathing is difficult.
7. An increased heartbeat, sweating, and chest pain. If your child experiences any of these symptoms or conditions, it's essential to seek medical attention to determine the underlying cause and appropriate treatment.

Diagnosis

To diagnose childhood asthma, a healthcare provider considers the symptoms, frequency, and medical history of the child. They may also need tests to rule out other conditions that have similar symptoms. These conditions include rhinitis, sinusitis, acid reflux, airway problems, dysfunctional breathing, and respiratory tract infections like bronchiolitis and RSV. Exhaled nitric oxide and lung function tests, such as spirometry, are common diagnostic tests for asthma in children. However, for younger children, the diagnosis may not be made until after observing symptoms for months or years. Skin prick tests may also be recommended for children with allergic asthma.

Management and Treatment

Complications

Complications of childhood asthma can include severe asthma attacks requiring emergency treatment or hospital care, permanent decline in lung function, missed school days or falling behind in schoolwork, poor sleep and fatigue, and symptoms that interfere with play, sports, or other activities.

Treatment

There are no specific treatments suggested for childhood asthma. However, it is important to manage asthma symptoms through various measures. These include:

1. Avoiding asthma triggers: Limiting exposure to allergens and irritants that trigger asthma symptoms.
2. Quitting smoking: Ensuring there is no smoking around the child, as tobacco smoke exposure during infancy is a significant risk factor for childhood asthma.
3. Encouraging regular physical activity: As long as the child's asthma is well-controlled, regular physical activity can help the lungs work more efficiently.
4. Regular check-ups: Consulting with the child's healthcare provider to make necessary treatment adjustments and monitor the child's asthma control.
5. Maintaining a healthy weight: Being overweight can worsen asthma symptoms, so it's essential to help children maintain a healthy weight. In cases where asthma symptoms are not well-controlled, medical professionals may prescribe medications to manage the condition. These can include bronchodilators, corticosteroids, and leukotriene modifiers, which work in different ways to help control asthma symptoms. Remember, it's crucial to consult with a healthcare provider to determine the most appropriate treatment plan for a child with asthma.

Preparing for medical consultation

To prepare for an appointment for childhood asthma, you should:

1. Make a list of your child's symptoms, including their severity and when they occur. Note if symptoms worsen in specific situations or environments.
2. Gather key personal information, such as your child's family history of allergies, asthma, or other heart or lung diseases, as well as any recent life changes.
3. List all medications, vitamins, and supplements your child takes, including doses.
4. Compile a list of questions to ask the healthcare provider. Some questions to consider include asking about the likelihood of asthma being the cause of your child's breathing problems, recommended tests, treatment options, and whether a specialist consultation is necessary.
5. Be aware of any pre-appointment restrictions, such as filling out forms or adjusting your child's diet before certain tests. Remember to bring this information with you to the appointment, and don't hesitate to ask additional questions during the consultation.
