23 Jul Why do some people get allergies while others don’t?
It is not fully understood why some people get allergies and others do not. Factors such as family history and genetics do have a role.34
Children born by Caesarean sector have more chance of being allergic than those born by natural childbirth and being exposure to tobacco smoke also increase the risk. Boys are more likely to be allergic than girls.34
Allergies can develop at any age but food allergies, for example, start at a young age and are often outgrown. Environmental allergies (such as hay fever) can develop at any time and the initial exposure or sensitisation may even occur before birth while in the womb. People can also outgrow allergies over time.34
