Question: can asthma lead to copd?
Answer: This group of diseases can include refractory (severe) asthma, emphysema and chronic bronchitis. Most people with asthma will not develop COPD, and many people with COPD don't have asthma. However, it's possible to have both. Asthma-COPD overlap syndrome (ACOS) occurs when someone has these two diseases at once.
