Asthma

Definition

Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to breathing difficulties. It often involves episodes of wheezing, shortness of breath, chest tightness, and coughing.

5 Must Know Facts For Your Next Test

1. Proper nutrition can help manage asthma symptoms by reducing inflammation and maintaining a healthy immune system.
2. Omega-3 fatty acids found in fish oil may reduce airway inflammation and improve lung function in asthma patients.
3. Vitamin D deficiency has been linked to increased asthma severity; thus, adequate levels are crucial for pulmonary health.
4. Obesity can exacerbate asthma symptoms due to increased inflammation and mechanical stress on the lungs.
5. Antioxidants like vitamins C and E can protect against oxidative stress in the lungs, potentially alleviating some asthma symptoms.
