Are allergies considered a disease?
Allergies are one of the most common chronic diseases. A chronic disease lasts a long time or occurs often. An allergy occurs when the body's immune system sees a substance as harmful and overreacts to it.
Allergies, also known as allergic diseases, are a number of conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis.
Allergens: Attention customers with food allergies. Please be aware that our food may contain or come into contact with common allergens, such as dairy, eggs, wheat, soybeans, tree nuts, peanuts, fish, shellfish or wheat.
Allergic reactions can range from mild to severe. In some severe cases, allergies can trigger a life-threatening reaction known as anaphylaxis. Hay fever, also called allergic rhinitis, can cause: Sneezing.
Food allergy is a serious and potentially life-threatening medical condition. Learn more about what food allergies are and what causes them. Food allergy is a serious and potentially life-threatening medical condition affecting 32 million Americans.
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.
Allergic diseases and symptoms occur because of an active immune system that reacts to things that are usually harmless, such as pollens, pet dander or foods.
Idiopathic Mast Cell Activation Syndrome
MCAS is a condition in which the patient experiences repeated episodes of the symptoms of anaphylaxis – allergic symptoms such as hives, swelling, low blood pressure, difficulty breathing and severe diarrhea.
Overview of the allergic immune response
Allergic diseases such as allergic rhinitis, asthma, and food allergy are characterized by the ability to make an IgE antibody response to an environmental allergen.
You have a legal obligation to provide information to consumers on the allergens that are in the food that you supply. These are the 14 allergens that you need to find out whether they are in the food that you make.
Is asking about allergies a legal requirement?
Food businesses need to tell customers if any food they provide contain any of the listed allergens as an ingredient. Consumers may be allergic or have intolerance to other ingredients, but only the 14 allergens are required to be declared as allergens by food law.
PHI includes all health data including EHR/EMRs, laboratory test results, medical histories, diagnoses, treatment details, insurance plan details, allergy information, unique identifiers, and demographic data.

Allergies can't be cured, but symptoms can be controlled using a combination of avoidance measures and medications, as well as allergen immunotherapy in properly selected cases. Last reviewed by a Cleveland Clinic medical professional on 11/30/2020.
Seasonal allergies, like other types of allergies, develop when the body's immune system overreacts to something in the environment, usually during spring, summer or fall when certain plants pollinate.
While allergies indicate that the immune system is not functioning correctly, a group of researchers' suggests otherwise. They argue that these allergies could be the body's mechanism of getting rid of toxic substances and that allergies are indicators of strong immune systems.
Allergies are not contagious.
Can someone be allergic to water? It may seem like a strange question, but the answer is “yes.” There is a very rare condition known as aquagenic urticaria (AU) where skin contact with water causes itchy, red hives or swelling. In severe cases, it can cause wheezing or shortness of breath.
Allergies involve an exaggerated response of the immune system and are among the most common chronic conditions worldwide. Infectious disease agents are also one of the leading contributors to debilitating and sometimes fatal conditions.
The most severe allergic reaction is anaphylaxis — a life-threatening whole-body allergic reaction that can impair your breathing, cause a dramatic drop in your blood pressure and affect your heart rate.
Allergies may simply worsen with age because you've been exposed to the triggers longer, Parikh says. "It takes repeated exposure to develop allergies. It can take a while for the immune system to decide it doesn't like that allergen."
Who has the most allergies in the world?
Australia has the highest rate of confirmed food allergy. One study found 9% of Australian one-year-olds had an egg allergy, while 3% were allergic to peanuts.
“In autoimmunity, there is a different type of T-cell involved than in allergies. In an autoimmune response, tissue destruction occurs. With allergies, the immune system overreacts to harmless allergens. Interestingly, this is the same type of response that expels viruses, parasites, and bacteria from the body.”
The researchers are the first to report that the allergen could promote the autoantibody development and subsequent autoimmune disease. The finding has been published in The Journal of Allergy and Clinical Immunology, which is the most-cited journal in the field of allergy and clinical immunology.

Sometimes, it is an allergic reaction to something in the air. Health experts estimate that 35 million Americans suffer from upper respiratory tract symptoms that are allergic reactions to airborne allergens.
