Asthma usually appears first in children and teens.  Certain substances or “triggers” cause an allergic reaction of the bronchial tubes (through which we breathe air into our lungs) and they become inflamed. This restricts the amount of air which can be inhaled with each breath.

Usually, the difficulty breathing comes in “episodes” or “attacks” which only last for a limited time. If the case is serious enough or not treated properly, an asthma attack can be fatal.

The number of cases of asthma in the U.S. (and other countries) saw a huge leap between the 70’s and 90’s. Some experts believe that this is because people have better hygiene and access to vaccines and antibiotics. This means their bodies are less likely to develop the immune cells to combat the allergens that cause asthma.  

Types of Asthma:

• Exercise induced asthma - Symptoms appear when exercising, especially if the air is cold and dry.
• Nocturnal asthma - Symptoms appear or become worse at night.
• Occupational asthma - Symptoms develop over time after being around chemicals or other irritants at work.
• Aspirin-induced asthma - Symptoms are triggered by medications (often aspirin)
