Predisposing factors to asthma include:
1. Genetic factors: Individuals with a family history of asthma are more likely to develop the condition.
2. Environmental factors: Exposure to allergens such as dust mites, pollen, pet dander, and mold can trigger asthma symptoms.
3. Respiratory infections: Viral infections such as the common cold can exacerbate asthma symptoms.
4. Smoking: Both active smoking and exposure to secondhand smoke can increase the risk of developing asthma.
5. Obesity: Being overweight or obese can increase the risk of developing asthma.
Investigations for asthma may include:
1. Spirometry: This test measures how much air you can exhale and how quickly you can do it. It can help diagnose asthma and assess the severity of the condition.
2. Peak flow measurement: This test measures how well your lungs are working by measuring how fast you can exhale air. It can help monitor asthma symptoms and assess the effectiveness of treatment.
3. Allergy testing: This can help identify specific allergens that may be triggering asthma symptoms.
4. Chest X-ray or CT scan: These imaging tests can help rule out other conditions that may be causing asthma-like symptoms.
Management of asthma may include:
1. Medications: Bronchodilators, corticosteroids, and other medications may be prescribed to help control asthma symptoms and prevent flare-ups.
2. Avoiding triggers: Identifying and avoiding triggers such as allergens, smoke, and respiratory infections can help prevent asthma symptoms.
3. Asthma action plan: Working with your healthcare provider to develop an asthma action plan can help you manage your condition and know what to do in case of an asthma attack.
4. Regular follow-up: Regular check-ups with your healthcare provider can help monitor your asthma symptoms and adjust your treatment plan as needed.
5. Lifestyle changes: Maintaining a healthy weight, quitting smoking, and staying physically active can help manage asthma symptoms and improve overall lung function.

## Predisposing Factors for Asthma
- Family history: Positive family history increases the risk.
- Atopy: Atopic individuals are more susceptible to developing asthma, such as those with eczema or allergic rhinitis.
- Genetic factors: Genetic variants in immune response genes, such as the HLA-DQB1 gene, are linked to asthma.
- Environmental exposures: Exposure to allergens (e.g., pollen, dust mites, pet dander), air pollutants (e.g., ozone, particulate matter), and secondhand smoke can trigger asthma in susceptible individuals.
## Investigations for Asthma
- Medical history and physical examination: Assess for symptoms, triggers, and risk factors.
- Lung function tests (spirometry): Measure lung volume and airflow to detect airway narrowing.
- Peak flow monitoring: Regular monitoring using a peak flow meter to track lung function.
- Allergy skin testing (scratch or prick test): Identify specific allergens that may trigger asthma.
- Chest X-ray: May rule out other lung conditions, such as pneumonia.
## Management of Asthma
Medications:
- Controller medications: Taken daily to reduce airway inflammation and prevent attacks. Examples include inhaled corticosteroids (e.g., budesonide, fluticasone), long-acting beta-agonists (e.g., salmeterol, formoterol), and leukotriene modifiers (e.g., montelukast).
- Rescue medications: Used during acute asthma attacks to rapidly open up airways. Examples include short-acting beta-agonists (e.g., albuterol, salbutamol) and inhaled anticholinergics (e.g., ipratropium bromide).
Trigger avoidance:
- Identify and avoid triggers such as allergens, air pollutants, and secondhand smoke.
- Use dust covers for bedding and furniture, regularly clean to remove dust mites.
- Keep pets out of bedrooms and use a HEPA filter to reduce dander.
Smoking cessation:
- Smoking worsens asthma symptoms and should be strongly advised against.
Education and self-management:
- Educate patients about their asthma and how to use their medications properly.
- Provide self-management strategies, such as breathing techniques and lifestyle modifications.
- Consider using a personalized asthma action plan to guide patients on when to adjust medications and seek medical attention.
Other strategies:
- Bronchial thermoplasty: A procedure that involves heating the airways to reduce airway wall thickness and improve airflow.
- Immunotherapy (allergy shots): Involves exposing patients to small amounts of allergens to gradually desensitize them.
- Surgery: Rarely used in severe cases to remove blockages or damaged lung tissue.
- Family history: Positive family history increases the risk.
- Atopy: Atopic individuals are more susceptible to developing asthma, such as those with eczema or allergic rhinitis.
- Genetic factors: Genetic variants in immune response genes, such as the HLA-DQB1 gene, are linked to asthma.
