Well, asthma is essentially a response to the body in the lungs that causes inflammation. It closes down the airways you use to breathe. Think about it kind of like a traffic jam on 75, if there is an accident and they close down one of the lanes in the road, there are fewer lanes for all of that traffic to go through. It makes it very hard to get the traffic through. A lot of people relate it to breathing through a straw, as well, where they just feel like they cannot move the air in and out of their lungs. So, you get this inflammation, it constricts the bronchioles. There are lots of other kinds of underlying things going on, but generally, that’s what causes the wheezing and the shortness of breath. There are many ways to treat that. The big thing, is the inflammation, getting rid of that, and they feel much better.
