What is Asthma?
Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to episodes of wheezing, shortness of breath, chest tightness, and coughing. These symptoms are often triggered by environmental factors such as allergens, smoke, pollution, or respiratory infections.
Symptoms of Asthma
Asthma symptoms vary from person to person but typically include:
- Wheezing: A high-pitched whistling sound when exhaling.
- Shortness of Breath: Difficulty breathing, especially during physical activity or at night.
- Chest Tightness: Feeling like something is squeezing or sitting on your chest.
- Coughing: Particularly at night or early in the morning, which may interfere with sleep.
