Asthma primarily affects which part of the body?

Asthma primarily affects the air passages, which include the bronchial tubes that lead to the lungs. In individuals with asthma, these airways become inflamed and narrowed, making it difficult for air to flow in and out of the lungs. This can lead to symptoms such as wheezing, coughing, chest tightness, and shortness of breath, especially during physical activity or at night.

Understanding how asthma impacts the air passages is crucial for managing the condition. Treatment often includes bronchodilators, which help to relax the muscles around the airways, and anti-inflammatory medications to reduce inflammation. By focusing on the air passages, it becomes clear how asthma can significantly impact a person's ability to breathe and their overall respiratory health.
