Could i have mild asthma and copd at the same time?

Absolutely: Asthma and COPD are technically two separate processes, though more research is showing similarities between the two. Both conditions are considered "obstructive" processes; that is, they obstruct air flow from the lungs out into the environment. Asthma typically affects the smaller airways, while COPD mostly affects the alveoli -- tiny air sacs at the very end of our airways.

In a way...: COPD means that there is chronic obstruction, whereas in asthma the obstruction is reversible. In copd, there may be a reversible component to the chronic obstruction and this is treated with bronchodilators. These same bronchodilators are used in the treatment of asthma as well.
