Asthma is a chronic respiratory condition in which the airways become inflamed, narrow, and produce extra mucus, making it difficult to breathe. It can range from mild to severe and often flares up in response to triggers such as allergens, cold air, or exercise. Although there is no cure, asthma can be effectively managed with proper treatment and lifestyle changes.

Symptoms

Asthma symptoms vary from person to person and may come and go depending on exposure to triggers. Common symptoms include:

  • Shortness of breath

  • Wheezing (a whistling sound when breathing)

  • Chest tightness or pain

  • Coughing, especially at night or early morning

  • Difficulty breathing during physical activity

  • Frequent respiratory infections

Causes

The exact cause of asthma is not fully understood, but it’s believed to result from a combination of genetic and environmental factors that affect the airways.

1. Genetic Factors
  • Family history of asthma or other allergic conditions (like eczema or hay fever) increases the risk.

  • Overactive immune response to certain triggers.

2. Environmental Factors
  • Allergens: Dust mites, pollen, pet dander, mold, cockroaches.

  • Air pollutants: Smoke, chemical fumes, vehicle emissions.

  • Weather: Cold air, sudden temperature changes, humidity.

  • Respiratory infections: Viral infections, especially in early childhood.

  • Occupational exposure: Dust, gases, or chemicals in workplaces.
