How Allergic Reactions Happen
Allergic reactions occur when your body comes in contact with something that it internally believes is harmful. This can be a food or any substance, such as pollen. As a reaction, the body produces immunoglobulin E or IgE, which are antibodies. These antibodies, in turn, attach themselves to cells which then release histamine. Histamine causes reactions such as inflammation, redness in the eyes, along with tears and an itchy feeling. If the reaction is strong enough anaphylactic shock can result. The IgE antibodies typically serve to fight infections but sometimes they attack the allergens instead.
There is also a condition called oral allergy syndrome, which is a reaction to pollen, not to a particular food. In this case, the immune system recognizes the pollen and similar proteins in the food and then causes an allergic reaction to it. This is not a true food allergy but is often confused as one.
Why Do Allergies Suddenly Appear
Allergies develop when your body thinks a substance such as animal hair, pollen, or mold is harmful. That substance awakens your immune system to release a chemical called histamine, which leads to your allergy symptoms. As you age, your immune system may start to weaken, so your response to an allergen also weakens.
Why Is Asthma Difficult To Diagnose In Older Adults
A diagnosis of asthma may be missed in an older person because symptoms of other health conditions are similar to asthma symptoms and may mask the specific symptoms. Asthma symptoms among older adults are more likely to take the form of coughing with the production of sputum from the lungs. Your physician might interpret those symptoms as being due to other illnesses, such as chronic bronchitis or congestive heart failure. In particular, heart disease and emphysema, much more common in older adults, especially smokers, can mimic asthma symptoms.
Good to know . . . One of the ways in which asthma is recognized among younger people is by the symptoms of wheezing and difficulty breathing following exercise. When older adults become inactive, the opportunity for asthma to present itself lessens. If you experience asthma symptoms wheezing, shortness of breath, tightness in the chest, chronic cough with your regular activities such as housework, shopping, gardening, or walking, be sure to talk with your physician as soon as possible.
When the asthma symptoms are not recognized correctly, they may remain untreated, likely worsening and creating very serious health risks.

What Things Cause Allergies
Common Airborne Allergens
Some of the most common things people are allergic to are airborne :
Common Food Allergens
Up to 2 million, or 8%, of kids in the United States are affected by food allergies. Eight foods account for most of those: cow’s milk, eggs, fish and shellfish, peanuts and tree nuts, soy, and wheat.
Other Common Allergens
- Insect allergy. For most kids, being stung by an insect means swelling, redness, and itching at the site of the bite. But for those with insect venom allergy, an insect sting can cause more serious symptoms.
- Medicines. Antibiotics are the most common type of medicines that cause allergic reactions. Many other others, including over-the-counter medicines , also can cause allergic reactions.
- Chemicals. Some cosmetics or laundry detergents can make people break out in hives. Usually, this is because someone has a reaction to the chemicals in these products, though it may not always be an allergic reaction. Dyes, household cleaners, and pesticides used on lawns or plants also can cause allergic reactions in some people.
Some kids also have what are called cross-reactions. For example, kids who are allergic to birch pollen might have symptoms when they eat an apple because that apple is made up of a protein similar to one in the pollen. And for reasons that aren’t clear, people with a latex allergy are more likely to be allergic to foods like kiwi, chestnuts, avocados, and bananas.

Mayo Clinic Q And A: Lactose Intolerance Can Develop At Any Age
DEAR MAYO CLINIC: What would cause someone to become lactose-intolerant later in life? Im in my 40s and have never had an issue with dairy, but, now, I cant seem to have it without problems. Do I need to see a doctor to be tested for allergies, or should I just avoid dairy?
ANSWER: Lactose intolerance isnt a true allergy, and it can develop at any age. In some people, lactose intolerance may be triggered by another medical condition, such as Crohns disease. In others, it develops without a specific underlying cause. It would be a good idea to have your condition evaluated by your doctor to confirm that what youre dealing with truly is lactose intolerance.
Lactose intolerance results from a problem with the carbohydrate lactose, a type of sugar found in dairy products. When you eat or drink dairy products, enzymes in your small intestine digest lactose, so the body can make energy. In people with lactose intolerance, a certain enzyme, called lactase, is missing from the body. When those people eat dairy products, the body has no way to break down the lactose. This leads to fermentation of the sugar in the intestines and triggers symptoms, such as diarrhea, nausea, abdominal cramps, bloating and gas.

Can Allergies Go Away With Time
The short answer is yes.
Even if you develop allergies as an adult, you may notice they start to fade again when you reach your 50s and beyond.
This is because your immune function is reduced as you get older, so the immune response to allergens also becomes less severe.
Some allergies you have as a child may also go away when youre a teen and well into your adulthood, perhaps making only a few appearances throughout your life until they disappear permanently.
Can You Develop Food Allergies As An Adult

Are You Born With Allergies Or Can You Develop Them
What are allergies and how do they develop? Are you born to them? Can they appear later in life? Here is all you need to know about them.
An allergy is an immune system response to a foreign substance in your body. Although this substance is not in itself harmful, your body perceives it to be a threat.
This triggers your immune system to produce chemicals called histamines to fight off this foreign substance. The histamine chemicals cause the allergic symptoms like itchy eyes, a runny nose, or hives.
It was traditionally assumed that allergies were simply something that you either had or didnt have. Either you were born with allergies and would suffer their effects your whole life, or you were not.
Scientists now know that things arent all that clear-cut you can actually develop or even outgrow an allergy.
Can Allergies Change As You Age
Some adults may actually experience a change in allergies as they age. From developing springtime allergies for the first time, to realizing that your family cat doesnt cause you the misery it once did allergies can shift and change at different phases of your life.

How To Manage An Allergy
In many cases, the most effective way of managing an allergy is to avoid the allergen that causes the reaction whenever possible.
For example, if you have a food allergy, you should check a food’s ingredients list for allergens before eating it.
There are also several medicines available to help control symptoms of allergic reactions, including:
- antihistamines these can be taken when you notice the symptoms of a reaction, or before being exposed to an allergen, to stop a reaction occurring
- tablets, capsules, nasal sprays or liquids that can be used as a short-term treatment for a blocked nose
- lotions and creams, such as moisturising creams these can reduce skin redness and itchiness
- steroid medicines sprays, drops, creams, inhalers and tablets that can help reduce redness and swelling caused by an allergic reaction
For some people with very severe allergies, a treatment called immunotherapy may be recommended.
This involves being exposed to the allergen in a controlled way over a number of years so your body gets used to it and does not react to it so severely.
How Are Childhood Allergies Different From Adult Allergies
Most people find out they have any allergy when theyre children. However, thats no reason to assume youre out of the woods if youve made it to adulthood without developing allergy symptoms. Adults arent immune to first-time allergies.
The immune system youre born with can change, and while we dont know the exact mechanism, we do know that adult-onset allergies are increasing.
At Riviera Allergy Medical Center, allergy specialist Dr. Ulrike Ziegner treats allergies in adults and children of all ages. Other than the age of onset, of course, there isnt much difference between adult and childhood allergies. The symptoms and treatment are identical.

Mayo Clinic Q And A: Reasons For Developing Allergies Later In Life Not Always Clear
DEAR MAYO CLINIC: I didnt have allergies when I was younger. But now in my 40s, I seem to get allergy symptoms during the spring and summer. Is it possible to develop allergies as an adult? Should I get tested? If so, what do allergy tests involve?
ANSWER: You can develop allergies later in life, and there is definitely value in getting tested to see if your symptoms are due to allergies. If they are, the test results will give you information about what youre allergic to and help guide you as you decide on treatment. Allergy tests usually involve a skin test, a blood test or both.
Allergy development typically has two phases. During the first phase, called sensitization, you come in contact with a harmless substance, and your body mistakenly starts making allergic antibodies, called IgE antibodies, to fight that substance. Those antibodies dont do anything until you are exposed to the substance, or allergen, again. At that time, the second phase starts. The allergen binds to the IgE antibodies. That sets off a cascade of immune reactions in your body, such as itchy or watery eyes, nasal congestion and sneezing, among others.
If, as in your situation, allergy symptoms develop but you arent sure what you might be allergic to, or even if your symptoms really are allergies, it is worthwhile to go through allergy testing. The tests can show what you are sensitive to, and knowing that can go a long way to customizing treatment to your specific situation.
