Asthma is a condition in which your airways narrow and swell and may produce extra mucus. This can make breathing difficult and trigger coughing, a whistling sound (wheezing) when you breathe out and shortness of breath.
- Airway irritability. People with asthma have sensitive airways that tend to overreact and narrow when they come into contact with even slight triggers
- Inflammation . Asthma causes red, swollen bronchial tubes in your lungs. This inflammation can damage your lungs. Treating this is key to managing asthma in the long run.
- Airway blockage. When you breathe as usual, the bands of muscle around your airways are relaxed, and air moves freely. But when you have asthma, the muscles tighten. It’s harder for air to pass through.
These problems may cause symptoms such as:
- Coughing, at night or in the morning
2. Wheezing, a whistling sound when you breathe
3. delay in breath
4. Pains, tightness, and pressure in your chest
5. sleeping problems caused by breathing problems
