76 Causes of Asthma
Genetics
A parent would pass asthma on to their kids. If a father or mother experiences this condition, there is a 25% chance that the baby would develop it later. The risk might increase to 50% if both people have asthma. Scientists have found the association between this health issue and more than 100 genes in human bodies. They would interact with the surrounding environment and become active in later generations. [7]
