Asthma Although we cannot cure asthma, we can control it. Everyone’s asthma is different, so you and your doctor need to create an asthma treatment plan just for you. This plan will include an Asthma Action Plan that will have information about your asthma triggers and instructions for taking your medicines. There are three changes in the airways when you have asthma: 1. Swelling inside the airways 2. Excess mucus that clogs the airways 3. Muscles tighten and squeeze around the airways This swelling, clogging, and muscle tightening makes your airways smaller or narrower. This makes it harder for air to flow easily through your airways, and it becomes harder to breathe. There are asthma medicines that target these three changes. They open your airways and make it easier to breathe. Follow up often with your doctor so you can control your asthma with the least amount of medicines and with the fewest side effects.
