Allergic bronchial asthma, often simply referred to as asthma, is a condition characterized by inflammation and narrowing of the airways in response to allergens. Infections can have a significant impact on asthma in several ways:
**1. Triggering Asthma Symptoms:
- Respiratory Infections: Common colds, flu, and other respiratory infections can exacerbate asthma symptoms. These infections can increase inflammation and mucus production in the airways, making asthma symptoms worse.
- Increased Sensitivity: Respiratory infections can make the airways more sensitive to allergens and irritants, leading to more frequent or severe asthma attacks.
**2. Impact on Immune System:
- Immune Response: Infections can affect the immune system’s response, potentially leading to increased asthma symptoms. For instance, viral infections can trigger an inflammatory response that worsens asthma control.
- Immune Activation: The body’s response to infections can include the release of inflammatory chemicals that exacerbate asthma inflammation and airway constriction.
**3. Increased Risk of Complications:
- Severe Asthma
