Asthma
What causes it?
If you have asthma, your airways are overly sensitive, making you susceptible to asthma attacks when you come in contact with certain "triggers". Some of these triggers are also common to allergy sufferers. They include:
- pet dander
- pollen
- mold
- cigarette smoke
- perfumes
- chemicals
Other triggers for people with asthma may include:
- exercise (known as exercise-induced asthma)
- stress and other emotional expressions such as fear, anger and frustration
- viral infections
- changes in temperature or humidity
- aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs)
- processed foods or drinks that contain chemicals, called sulfites, as a preservative
- certain beta-blocker drugs, including those in some eye care medications
- gastroesophageal reflux disease, a condition in which stomach acids back up into your food pipe
Sometimes, an asthma attack occurs for no apparent reason.
