=**There are three main factors that cause asthma:** =

Genes

 * ====There are many genes that have been linked with asthma, but if you inherit these combination of genes, it only increases your chances of getting asthma.====
 * ====If you have a parent that has asthma, you have a 40 to 50 percent increased chance of getting asthma yourself; if two parents have asthma, than the risk is 80 percent or more====

Allergies

 * ====Most people with asthma also have allergies.====
 * ====This is a problem since an allergic attack can also induce an asthma attack.====
 * ====Having allergies can increase your chances of getting asthma====

Environment

 * ====There has been no clear link between asthma and environment yet, but the number of asthma cases have doubled in the past decade, and scientists suspect that it has to do with environmental changes.====
 * =====States Dr. Stephen Redd from the CDC, " The genetic makeup of the population couldn't have changed enough to see the increases in asthma that are being seen in many developed countries...so there's got to be some kind of environmental exposure, but exactly what that is really isn't known."  =====
