Airway hyperreactivity

Definition

Airway hyperreactivity is an exaggerated response of the airways to various stimuli, leading to narrowing and obstruction of airflow. It is commonly associated with conditions such as asthma and can be influenced by nutritional status.

5 Must Know Facts For Your Next Test

1. Airway hyperreactivity can be aggravated by poor nutrition, particularly deficiencies in antioxidants such as vitamins C and E.
2. Diets high in omega-3 fatty acids have been shown to reduce airway inflammation and hyperreactivity.
3. Obesity is a significant risk factor for airway hyperreactivity due to increased inflammatory markers and mechanical pressure on the lungs.
4. Magnesium deficiency has been linked to increased airway reactivity; magnesium-rich foods may help manage symptoms.
5. Probiotic supplementation may improve lung function and reduce airway hyperreactivity by modulating gut-lung axis interactions.
