Children with food allergies, for instance, are as much as four times more likely to have other allergic conditions, including asthma. More than 100 genes are associated with allergies, although only one or two genes affect any given population. Some of these genes affect the immune response; others affect lung and airway function.

Allergens are typically harmless substances that trigger an immune response and cause a reaction in people who are allergic. The allergic reaction occurs if the person inhales, touches, swallows, injects, or somehow comes into contact with the allergen. Allergic reactions can be mild, severe, or even life-threatening.

Normally, the immune system protects the body against harmful substances, such as viruses or bacteria. If you have allergies, "your body responds to allergens as if they were invaders," explains Clifford Bassett, MD, a clinical assistant professor at New York University Langone Health in New York City and the author of The New Allergy Solution. "Your body exaggerates the immune response.

That's what causes histamine release and other things that cause allergy misery."Histamine also acts as a neurotransmitter in the brain, sending messages between cells. It plays a key role in many different physiological functions, such as telling your stomach to produce acid to digest food or helping regulate your sleep-wake cycle. When your immune system reacts to an allergen, it produces an antibody called immunoglobulin E (IgE).

The production of IgE is part of your body's attempt to destroy the allergen and protect itself. Your blood vessels dilate and become leaky, so white blood cells that fight infection and other protective substances leave the blood vessels to attack the invader.

In the process, the IgE antibodies signal other cells to release certain chemicals, such as histamine in the local tissue and blood stream. Too much histamine or excessive release in the body can cause an unwanted response that leads to skin, nose, throat, and lung irritation or more severe symptoms of anaphylaxis.In this way, a normally protective process creates a cascade of what we know as allergy symptoms in response to harmless allergens.

There are other types of allergic reactions, such as delayed hypersensitivity reactions, which includes contact dermatitis from poison ivy or a nickel allergy — these are mediated by T cells in the immune system rather than antibodies.The most common allergens that trigger allergic reactions include:
PollenDust mitesPet dander or furCockroachesMold sporesFoods (eggs, fish, milk, nuts, wheat, soy, shellfish, and others)Insect stings or bites (from wasps, bees, mosquitoes, fire ants, fleas, horseflies, black flies, among others)Medicines (penicillin, aspirin, and others)LatexHousehold chemicalsMetals (especially nickel, cobalt, and chromates)
Seasonal Allergies
Certain allergies can strike at any time of year. Seasonal allergies, on the other hand, occur at times of the year when certain types of outdoor allergens are predominant. "You can have both," says Dr. Bassett.And about two-thirds of people with seasonal allergies actually have year-round or persistent allergies, according to the American College of Allergy, Asthma & Immunology.

Seasonal allergies are most often triggered by mold and pollen from trees, grasses, and weeds such as ragweed. The allergic reaction occurs during the weeks or months when the plant pollinates. Allergy triggers may vary depending on geographic location and climate, but relocating to avoid seasonal allergies generally doesn't help.

Changes in the duration and intensity of pollen and mold seasons mean more people are exposed to allergens for longer amounts of time. "That's a longer period of time for your eyes and nose and throat to become symptomatic as a result," Bassett says.In a 2015 survey of allergists, 63 percent of respondents felt climate change was causing an increase in allergic symptoms among their patients.
How Are Allergies Diagnosed
The first step in diagnosing allergies is an evaluation by your physician to review your symptoms and medical history and to rule out other potential medical problems.

"With a cold, you're more likely to have a sore throat, decrease in appetite, and you just don't feel well."Allergy symptoms last as long as you are exposed to an allergen, whereas a cold or the flu usually runs its course within two weeks. Flu symptoms tend to be more severe than cold symptoms, accompanied by a fever and possibly headache, fatigue, and aches and pains.

Allergies or COVID-19 Here s How to Tell the Difference
"If you have a cold, there's no real good treatment other than waiting five to seven days," Bassett says. But for a nonsevere allergy, "if you use an antihistamine or nasal steroid spray, they're usually very effective."
The coughing and other respiratory symptoms of COVID-19, the infection caused by the SARS-CoV-2 coronavirus, may also be confused with allergies. One notable difference is that fever, which often accompanies COVID-19 and the flu, isn't usually a sign of allergies.

Another difference: Allergic coughing is typically the result of postnasal drip, unlike the dry COVID-19 cough. Other conditions that produce allergy-like symptoms include:Non-allergic rhinitis, which mimics allergic rhinitis but does not involve the immune system (at least one-third of people with rhinitis symptoms don't have allergies)
Sinus infectionsNasal polyps or a deviated septum
Prognosis of Allergies
There are different prognoses for different types of allergies.Rhinitis Typically, allergic rhinitis peaks in adolescence and gradually improves as people get older.

Duration of Allergies
Some allergies last for a number of years and then go into remission, and others can last a lifetime, says John Bosso, MD, the director of the otorhinolaryngology allergy clinic at Penn Medicine in Philadelphia. "For example, a certain percentage of people with asthma and allergic rhinitis can get better with time — often it improves in puberty, especially in boys," says Dr.

If your allergies are less severe or merely annoying, you may be able to find an effective over-the-counter (OTC) treatment. A pharmacist may be able to help you choose the best option based on your symptoms. OTC medicines include antihistamines and decongestants and nasal steroid sprays (which relieve congestion and previously were prescription).

The National Allergy Bureau provides pollen and mold updates by region.Use a high-efficiency particulate air filter (HEPA). HEPA filters trap airborne allergens.If you already have a cat or dog that you're allergic to, don't sleep near the pet, and wash your hands promptly after contact. Don't touch your eyes, nose, or mouth after touching an animal.If you're trying to figure out which allergens might cause or worsen your symptoms, keep a log. Write down what you eat and all your activities to help pinpoint triggers.Wash bedding frequently and use hot water to lessen your exposure to dust mites, pet dander, pollen, and other airborne irritants.If you have severe allergies, a medical alert bracelet or necklace can aid in getting you medical assistance in an emergency.

Minorities are less likely to be included in clinical trials that test the efficacy and safety of drugs, and this can lead to disparities in treatment. This seems to be especially important in asthma, as there is evidence that in some instances Black and white populations may respond differently to certain medications, as suggested in a study published in the New England Journal of Medicine. Black and Hispanic Americans are also at a higher risk for exposure to air pollution, which contributes to worsening of allergies and asthma.
