Asthma

Intrinsic asthma, or non-allergic asthma, is triggered by factors other than allergens, such as infections, stress, cold air, or exercise.
It involves inflammation and narrowing of the airways, similar to allergic asthma, but without an immune-mediated allergic response.
Symptoms include wheezing, coughing, shortness of breath, and chest tightness, often worsening during viral infections or physical exertion.
Triggers may include respiratory infections, air pollution, strong odors, smoke, or emotional stress.
Management focuses on avoiding triggers, using inhaled medications (bronchodilators, corticosteroids), and monitoring lung function.
