Risk factors
By Mayo Clinic staffYou may be at increased risk of developing an allergy if you:
- Have a family history of asthma or allergies. You're at increased risk of allergies if you have family members with asthma or allergies such as hay fever, hives or eczema.
- Are a child. Although you can become allergic to something at any age, children are more likely to develop an allergy than are adults. Children sometimes outgrow allergic conditions as they get older. However, it's not uncommon for allergies to go away and then come back sometime in the future.
- Have asthma or an allergic condition. Having asthma increases your risk of developing an allergy. Also, having one type of allergic condition makes you more likely to be allergic to something else.
