美国梅奥诊所:我家宝宝最近有几次气喘,是不是得了哮喘?
Answers from Jay L. Hoecker, M.D.
Not necessarily. Not all children who have wheezing episodes will develop asthma, and not all children who have asthma wheeze.
Wheezing is a whistling sound made during breathing. Because a child's airways are so small, any lower respiratory infection — such as respiratory syncytial virus (RSV) — can cause wheezing in children. Sometimes a choking episode causes wheezing. In other cases, factors such as a structural abnormality in the airways or an issue with the vocal cords contribute to wheezing in children.
Wheezing is also a classic sign of asthma — especially recurrent wheezing. In addition to wheezing, other signs and symptoms of asthma in a young child might include:
- Recurrent difficulty breathing
- Recurrent chest tightnes
- Frequent coughing
- Coughing that gets worse after active play or changes in the weather
