URBANA, IL (Chambana Today) – If you didn’t suffer from seasonal allergies as a child, you might consider yourself one of the lucky ones. But for those in their 40s or 50s suddenly feeling miserable during the spring and fall, adult-onset allergies are becoming increasingly common.

According to recent data from the Centers for Disease Control and Prevention (CDC), nearly 1 in 3 adults in the U.S. have seasonal allergies, eczema, or food allergies. Of these, nearly 75% are older than 45. Many of these individuals develop allergies later in life or were not diagnosed until adulthood.

Experts remain unsure about why allergies develop in adulthood, but there are theories. Some suggest that moving to a new geographic area, a weakened immune system, or owning a pet for the first time can trigger allergic reactions. Additionally, a severe allergic reaction during childhood may increase the likelihood of developing allergies as an adult.

While many people outgrow their childhood allergies by their 20s or 30s, others may develop them at any point in life. “People will have them as kids and sometimes grow out of them,” says Breanne Gendron, a nurse practitioner with OSF HealthCare. “But sometimes something starts bothering you as you age, and that’s when we teach you how to manage your symptoms.”

During the spring and fall, pollen from trees, grass, and ragweed can cause allergic reactions. Molds and fungi thrive in warm weather, and dust mites are a year-round problem. The most common symptoms are sneezing, itchy eyes, and a runny nose. However, Gendron has noticed an increase in sinus infections among adults with allergies, a symptom less commonly found in younger patients.

“Untreated allergies can lead to extra congestion, which may result in sinus infections,” Gendron says. “When you feel pressure in your face and generally rundown, we treat that as well.” To manage these symptoms, Gendron recommends using a combination of antihistamines, eye drops, and steroid nasal sprays. Allergy shots might be needed for more severe cases. A doctor can help determine the specific allergens with a skin test.

Gendron also offers practical tips for minimizing symptoms. She advises eliminating carpet from the bedroom, regularly washing sheets, and taking a shower before bed to remove pollen. Keeping windows closed at night can prevent allergens from entering your home. For those who know their triggers, such as mowing the lawn or raking leaves, wearing a mask while doing outdoor chores can help limit exposure. Gendron also suggests taking allergy medication before engaging in these activities to reduce reactions.
