Risk Factors of Asthma

Various factors can trigger or increase the risk of asthma. These include:

1. Genetics: The presence and severity of asthma may be influenced by a person’s genetic makeup.

2. Air Pollution: Exposure to outdoor pollutants like nitrogen dioxide and diesel particulates is linked to increased asthma symptoms.

3. Diet: Diets low in antioxidants such as Vitamin A, Vitamin C, Vitamin D, magnesium, and selenium may contribute to the development of asthma.

4. Viral Infections: Respiratory tract infections caused by viruses during childhood can be a factor in developing asthma later in life.

5. Allergens: Environmental allergens like pollen, dust, or mites can trigger asthma attacks.

6. Medications: Certain medicines like aspirin and beta-blockers can cause asthma attacks in some individuals.

7. Exercise: Physical activity may worsen asthma symptoms and make breathing difficult.

8. Chronic Sinusitis: Post-nasal drip from sinusitis can trigger coughing and throat irritation, worsening asthma symptoms.

9. Insects or Plants: Some individuals may be allergic to specific plants or insects, acting as triggers for asthma.

10. Obesity: Being overweight increases the risk of asthma and related symptoms such as shortness of breath and wheezing.

11. Stress: Emotional factors like stress can not only trigger anxiety but also asthma symptoms like breathlessness.

12. Smoke: Exposure to smoke or chemical irritants, such as fumes, can lead to asthma symptoms like wheezing and shortness of breath.

Diagnosis of Asthma

Asthma is often considered when a patient has a history of recurring dry cough, especially at night and early morning, accompanied by symptoms like chest tightness, shortness of breath, and wheezing. Several diagnostic tests can help confirm asthma:

1. Physical Examination: During a physical exam, the doctor checks for signs of allergic reactions, such as swelling or drainage in the eyes, ears, nose, or throat. They also listen for wheezing or whistling sounds in the chest and lungs, indicating inflammation and airway constriction.

2. Blood Tests: Various blood tests may be recommended to assess inflammation levels, antibodies, and eosinophils (a type of immune cells). These tests include a complete blood count (CBC), immunoglobulin E (IgE), and absolute eosinophil count (AEC).

3. Pulmonary Function Test: These tests evaluate airway obstructions. If there is clinical suspicion despite normal lung function tests, additional assessments like post-exercise tests or allergen challenge tests may help determine bronchial hyperresponsiveness, especially in adults.

4. Chest X-ray: In severe cases, chest X-rays can reveal hyperinflation of the lungs, providing insights into the condition.

5. Allergy Panel/Asthma/Rhinitis Screening Test: If an allergic trigger is suspected, an allergy diagnosis may be recommended. This includes a thorough medical history, a skin prick test, and a specific IgE (immunoglobulin E) test to identify potential allergens.
