Is asthma hereditary?

No, asthma itself is not hereditary, but there does seem to be a hereditary component to the tendency to develop asthma. This means asthma tends to run in families. If neither parent has asthma, the chances of each of their children having asthma are less than if one or both parents have asthma.

Children don't inherit asthma itself, but the tendency to develop it. Whether or not an individual develops asthma is also now thought to be influenced by their exposure, particularly in childhood, to various other things such as viral infections, irritants, allergens, passive smoking if one or both parents are smokers.
