Are Allergies Genetic

How to Know If You Have Allergies | Stephen Dreskin, MD, PhD, Allergy and Immunology | UCHealth

As many at 50 million people in the United States have some type of allergy. The tendency to develop allergies is often but not always hereditary, passed down from generation to generation. However, not everyone in a family will be allergic to the same things and some wont be allergic at all.

How Old Is Your Child

Most people’s asthma starts by age 6, says Fernando Martinez, MD, a pediatric pulmonologist who leads the University of Arizonaâs Asthma and Airway Disease Research Center.

âIt is rare you will develop asthma . Nothing is impossible, but itâs much more unlikely,â he says.

You can get allergies at any point in your life. But outdoor allergies tend to arrive between ages 4 and 6, McMorris says. Indoor allergies can start as early as age 3, but not always. For instance, âa child can take a while to develop allergies to a pet,â he says.

It may be time for an allergy test if the symptoms seem to be worse when your kid is at home and you have a furry pet.

Also, does your child have eczema? This itchy skin condition often goes hand in hand with allergies. And if your child has eczema and allergies, and they are younger than 6, âthereâs a high probabilityâ they will get asthma, Martinez says.

Dealing With Nonallergic Rhinitis

Start by trying to avoid known triggers. If a drug is the culprit, ask your doctor about trying an alternative.

If you cant avoid the trigger, first see whether a daily saline rinseoften applied using tools such as neti pots or bulb syringeshelps ease your symptoms.

You can also consider using a spray that contains the prescription nasal antihistamine azelastine . Steroid sprays can also work well for persistent symptoms.

    Pollen allergy is an allergy to pollen, tiny particles released by trees, grasses and weeds. Pollen grains float through the air in spring, summer and fall or year-round in areas with mild winters.

    Symptoms of pollen allergies may be:

    • sneezing spells
    • congestion
    • itchy throat

    Pollen allergies may occur throughout the year. Tree pollens are common in late winter and early spring, followed by grasses in late spring and summer. Then towards the end of the summer allergies from the pollen released by weeds such as ragweed are more common.

    There are ways to limit exposure to pollen allergens and minimize symptoms. However, pollen allergies may require medications to control symptoms, so treatment options should be discussed with a board-certified allergist.

    Molds are microscopic organisms called fungi, found virtually everywhere, indoors and out. Molds reproduce through spores spread by water, insects or air, so tiny and lightweight they can float through the air like pollen. These spores can be inhaled and cause allergic symptoms.

    • Moderate reactions include symptoms that spread to other parts of your body. Symptoms may include itchiness, hives, and/or swelling and trouble breathing.
    • A severe allergic reaction, known as anaphylaxis, is a rare, life-threatening emergency in which your bodys response to the allergen is sudden and affects the whole body. Anaphylaxis may begin with severe itching of your eyes or face. Within minutes, more serious symptoms appear, including throat swelling , abdominal pain, cramps, vomiting, diarrhea, hives and swelling . You may also have mental confusion or dizziness, since anaphylaxis may cause a drop in blood pressure.

    Note What Time Allergy Symptoms Occur

    How to Tell if You Have a Food Allergy

    Noting the time span and exact time you have these allergic reactions can help you discover the cause. A cold generally lasts between five to seven days. If allergy symptoms last for more than two weeks or for months at a time, you may have a seasonal allergy.

    If your symptoms worsen during the spring or fall, when pollen counts are higher, then you are more likely to have a seasonal allergy. If you have allergic reactions around the clock, you should check to see if there are allergens in your environment like dust mites.

    How To Recognize An Allergy

    Although you can’t always tell the difference between an allergy and something else for sure, here are some general tips to help distinguish an allergy:

    Make a checklist of symptoms. Differentiating nasal allergy problems from cold or viral conditions spells relief for most people because nasal allergy symptoms affects between 10% to 30% of all adults, but treatment can reduce those symptoms in about 85% of those sufferers. So if you’re not sure if you have one or the other, inventory your symptoms.

    “If the list encompasses fever, greenish or yellow-colored mucus, or joint and muscle pain, then it’s more likely a cold,” Resnick says. But if you’ve got sneezing itchy, red, or watery eyes clear nasal discharge or your nose, throat or ears feel scratchy — then he says you’re probably dealing with an allergy.

    Timing is everything. The duration and time of year the symptoms occur can be strong clues to identifying their root cause. “Once you find that the symptoms are lasting two or three weeks or even a few months, we say it’s probably not a routine cold,” Goldsobel says.

    If nasal allergy symptoms get worse in the spring or fall when pollen counts are generally higher, then it’s more likely to be an allergy. “However, if they happen all the time, then you still have to figure out if you have a year-round allergy, which is commonly due to indoor allergens like dust, pets, or cockroaches,” Resnick says.

    Why Does A Latex Allergy Happen

    When youre exposed to latex and you have a latex allergy, it causes a chain reaction in your body that starts in your immune system, the AAAAI explains. Your immune system, which controls how your body defends itself, overreacts by producing antibodies called Immunoglobulin E that can react with contaminating proteins found in latex. The antibodies then travel to cells that release chemicals, causing an allergic reaction in your body.

    Its unclear why, exactly, some people develop a latex allergy, but the Mayo Clinic says that repeated exposure may increase sensitivity to the material. So people with spina bifida , health care workers, those who have been through several surgeries or medical procedures, and rubber industry workers are at the highest risk of having a latex allergy.

    Just a heads up: There seems to be a link between having a latex allergy and reactions to certain foods, like avocados, chestnuts, kiwis, and bananas. Its likely because they have similar proteins to the ones in natural latex, according to the AAAAI. If those foods give you trouble, theres a chance you could have an issue with latex.

    When You Can’t Figure It Out On Your Own

    Sometimes it’s nearly impossible to tell if you’re having an allergy short of being examined by a doctor. The prime example: a skin allergy from contact with a substance.

    “For the person who is having the symptoms, there is probably no defining difference between allergic contact dermatitis and irritant contact dermatitis â both are going to irritate the skin the same way,” Goldsobel says. Unless you’re tested, it’s not really possible to tell if you’re having an immune response or not. But in the end, the solution is usually the same â avoid contact with whatever is causing the irritation.

    If allergy symptoms continue to bother you and at-home treatments fail to work, or if you’re still unable to tell if you’re having an allergy or something else, then it’s time to talk to your primary physician or see an allergist for a full evaluation.
