Persistent Asthma

Persistent asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to difficulty breathing. This comprehensive guide aims to provide a simplified understanding of persistent asthma, covering its types, causes, symptoms, diagnostic tests, treatments, preventive measures, and when to seek medical attention.

Persistent asthma is a long-term condition where the airways in the lungs become inflamed and narrow, making it hard to breathe. Unlike occasional asthma, which may occur due to specific triggers, persistent asthma involves ongoing symptoms that can affect daily life.

Types of Persistent Asthma:

1. Mild Persistent Asthma: Symptoms occur more than twice a week, but not daily.
2. Moderate Persistent Asthma: Symptoms occur daily, requiring medication for control.
3. Severe Persistent Asthma: Symptoms are continuous and often require multiple medications for management.

Causes of Persistent Asthma:

1. Genetics: Family history of asthma increases the risk.
2. Environmental Allergens: Exposure to pollen, dust mites, pet dander, or mold.
3. Air Pollution: Inhalation of pollutants such as smoke, fumes, or chemicals.
4. Respiratory Infections: Viral infections can trigger asthma symptoms.
5. Obesity: Being overweight or obese can worsen asthma.
6. Smoking: Active or passive smoking can exacerbate symptoms.
