Inflamed Bronchial Tubes

• Asthma causes bronchial tubes to become inflamed. This inflammation then causes the airways to become constricted, making breathing difficult.
  
  

Swelling of Airway Linings

• Asthma also causes airways within the lungs to swell. This also causes the airways to become constricted.
  
  

Tightening of Bronchial Wall Muscles

• In addition, asthma causes the muscles within the bronchial wall to tighten. This tightening causes breathing difficulties.
  
  

Excess Mucus Production

• Asthma also causes airways within the lungs to produce excess mucus that obstructs airways and causes breathing problems.
