Bronchial hyperreactivity is a condition characterized by an increased sensitivity of the airways to various stimuli, often leading to bronchoconstriction and respiratory symptoms. It is a hallmark feature of asthma and can be triggered by allergens, irritants, or exercise, necessitating careful management to prevent exacerbations.

Bronchial Hyperreactivity

Increased sensitivity of the airways

Bronchoconstriction is the narrowing of the airways in the lungs due to the tightening of surrounding smooth muscle, often triggered by allergens, exercise, or respiratory infections. This condition leads to difficulty in breathing and is a hallmark symptom of asthma and other respiratory disorders.

Bronchoconstriction

Respiratory symptoms are clinical manifestations that indicate issues within the respiratory system, ranging from mild conditions like a common cold to severe diseases such as pneumonia or lung cancer. Understanding these symptoms is crucial for early diagnosis and management of underlying respiratory conditions, ensuring better patient outcomes.

Triggers of bronchial hyperreactivity

Allergens are substances that can cause allergic reactions in susceptible individuals, triggering immune responses that range from mild to severe. Understanding allergens is crucial for managing allergies, which involves identifying specific allergens, avoiding exposure, and sometimes undergoing treatments to desensitize the immune system.

Allergens

Irritants are substances that cause inflammation or discomfort to the body, often affecting the skin, eyes, or respiratory system. They can be chemical, physical, or biological in nature and their impact depends on exposure duration and individual sensitivity.

Irritants

Exercise is a physical activity that enhances or maintains physical fitness and overall health and wellness. It is crucial for preventing chronic diseases, improving mental health, and increasing longevity by promoting a balanced lifestyle.
