Symptoms and triggers of asthma

Symptoms of asthma during pregnancy are the same as those of asthma at any other time. However, each woman with asthma responds differently to pregnancy. You may have milder symptoms or more severe symptoms, or your symptoms may be pretty much what they are when you aren't pregnant.

In general, asthma triggers are the same during pregnancy as at any other time. Like the situation with asthma symptoms, during pregnancy sensitivity to triggers may be increased, decreased, or stay about the same. These differences are attributed to changes in hormones during pregnancy. Common triggers of asthma attacks include the following:

• Respiratory infections such as a cold, flu, bronchitis, and sinusitis: Both bacterial and viral infections can trigger an asthma attack.
  
  
• Cigarette smoke (firsthand or secondhand)
  
  
• Gastroesophageal reflux disease (GERD), or regurgitation of stomach contents up the esophagus or "food pipe" 
  
  
• Smoke from cooking or wood fires
  
  
• Emotional upset
  
  
• Food allergies
  
  
• Allergic rhinitis (hay fever or seasonal allergies)
  
  
• Changes in weather, especially cold, dry air
