The link between immunology and asthma is essential for understanding why asthma symptoms occur. Asthma happens when the immune system reacts too strongly to harmless triggers like pollen, dust, mold, or pet dander. This reaction causes airway inflammation, swelling, and tightening, which leads to trouble breathing.

Researchers have found that asthma is driven by immune cells and chemical signals that become overactive. When the immune system identifies a trigger, it releases substances that cause mucus buildup and airway sensitivity. This explains why symptoms vary widely from person to person.

Short-term flare-ups and long-term asthma patterns both depend on how reactive the immune system is. Genetics, allergies, infections, and environmental exposure all influence this reaction. Understanding this helps people manage their symptoms more effectively.

Modern treatments now target the immune system directly. Biologic medications work by blocking specific immune responses linked to inflammation. These therapies are especially useful for people with severe or persistent asthma.

People with asthma can improve control by learning how their immune system reacts and identifying what triggers their symptoms.

Key Points:

• Asthma is closely connected to immune system activity.
• Allergens and irritants trigger an exaggerated immune response.
• Immune cells like eosinophils and mast cells cause airway inflammation.
• Genetics and environment influence asthma severity.
• Biologic therapies target immune pathways for better symptom control.
• Understanding immunology helps improve long-term asthma management.
