How does allergy manifest – symptoms in children and adults. Signs of allergies, video

The manifestation of an unhealthy sensitivity of an organism to a certain substance is called an allergy. Failure in the immune system leads to the fact that harmless products are perceived as something dangerous, a protective reaction is launched. It is important to know how allergies of any kind manifest. This will help to take correct measures. If a parent causes some kind of allergen, this is passed on to the children..

What are the symptoms of allergies in adults and children

There are three main forms of allergy manifestations: respiratory, food, and skin. In the first case, the respiratory tract is affected. A common respiratory disease of an allergic nature is rhinitis. A severe option is bronchial asthma. If a person is exposed to a respiratory allergy, its exacerbation causes most pungent odors, cigarette smoke.

On cats and dogs

Signs of an allergy appear within 5 minutes after communicating with the pet, gradually increase and after 3 hours reach a maximum. Cat allergens cover the clothes of the owner of the cat, can cause an attack in the patient, even in such an indirect way. An allergy to animal hair is less common than to other components, such as dandruff, particles of skin. Symptoms of an allergy to cats and dogs:

  • lacrimation
  • coughing and sneezing;
  • dyspnea;
  • bronchospasm;
  • hives.

Food allergies

An unhealthy reaction occurs after eating, in the period from a few minutes to a couple of hours. In babies, eggs often cause an allergic reaction. An allergen can be such a familiar product as tea. Signs of food allergies are swelling of the mouth, lips, throat, and itching in this area. Then nausea, vomiting and diarrhea join. In severe cases, Quincke’s edema, anaphylactic shock are possible..

For milk

Cow protein allergy (casein) can often occur in infants. It is important to know how this allergy manifests itself. This will help to quickly eliminate an annoying product. A common occurrence is an allergy to breast milk in a baby. Symptoms

  • profuse regurgitation after eating;
  • painful colic;
  • flatulence;
  • loose stools;
  • urticaria, rash, red spots that stand out clearly in the photo.

About a quarter of people have milk allergies in adults. Often confused with a reaction to lactose. Intolerance to this substance occurs due to a lack of enzymes. From this, lactose – undigested sugar – settles in the large intestine. This leads to bloating. Milk causes a reaction almost immediately after a person has taken dairy products.

On honey

Honey intolerance is associated with the presence of pollen in it. When reacting to this product, the manifestation of allergies on the skin is primarily noted. It turns red, rashes, blisters, swelling appear, and dermatitis develops. Other symptoms:

  • sore throat, bronchospasm, sneezing, profuse runny nose;
  • there is an allergy in the throat: the larynx swells, changes in the mucous membrane occur;
  • lacrimation, redness of the eyes;
  • digestive upset.

The baby has a mixture

After the introduction of complementary foods, newborns may develop intolerance to a certain mixture. Normally, the baby belches after eating 1-2 times. In case of allergy, the amount rises to 5-7 times. Stool problems begin – constipation or diarrhea. There is a runny nose, cough, skin symptoms. Rashes appear in the face of the baby, abdomen, buttocks.

On the nuts

Unhealthy sensitivity to any nuts appears at an early age, and in some people persists for life. Often the allergen is peanuts, walnuts. The reaction occurs after eating a product containing even a few nuts. Signs:

  • in the area of ​​the chin, neck and collarbone – a rash that is very itchy;

  • in severe cases, anaphylactic shock is possible (from sweet foods of protein origin).

On mushrooms

Sensitivity to fungi manifests itself in the process of processing them, or in contact with the products in the production of which they were used. The first reaction is from the respiratory system, the way an allergen enters the body. If mushrooms have been eaten, skin and digestion signal an allergy. When fungal spores “attack” the mucous membrane of the eyes, throat and nose, conjunctivitis, rhinitis and cough.

For seafood

Fish (especially red), shrimp, sushi are often allergens. The reason is in the protein molecules, which the sensitive body perceives as a dangerous compound. The response of the body:

  • tingling in the mouth;
  • vomiting and nausea;
  • redness of the skin;
  • the appearance of rashes, blisters;
  • the occurrence of suffocation, in severe cases – anaphylactic shock.

For medication

Intolerance to certain medications in severe cases can cause damage to body systems, disruption of the internal organs. How this allergy manifests itself is especially important to know. The cause of the painful reaction is the usual medication – iodine and novocaine, Espumisan in newborns, vitamins. Antibiotics lead to the development of such reactions..

To dust

Carpets and cabinets are covered by a whole range of substances: animal hair, dandruff, particles of human hair and skin, insect excrement, fungal spores, book dust. All these are allergens. The main one is a dust mite. Acute allergic symptoms appear at night or in the morning upon waking, when the apartment is cleaned, the condition worsens. In rooms with a large number of carpets, reactions intensify.

Signs of Seasonal Allergies

Allergic rhinitis is the main form of the disease. It manifests itself as a constant nasal congestion, itching and runny nose. Seasonal allergy increases during the flowering period of plants. There is another type of response to climate change. An allergy to cold is manifested on the face: this part of the body is open. After returning home, the patient’s cheeks are covered with red spots that do not disappear, but intensify. The sun can also be an allergen, intolerance to its radiation is called photodermatitis..

For household chemicals

Irritants can be detergent, dishwashing detergent, spray fresheners, and so on. The initial contact with the allergen causes sneezing, flows abundantly from the eyes and nose, and an attack of suffocation occurs. Further lesions of the skin and digestive tract develop. After termination of contact with the allergen, seizures quickly stop.

All about the manifestations of allergies

If there is a suspicion of an allergy, experts advise tracing the culprit. Donating blood to all allergens to prescribe treatment is a troublesome and expensive task. Just write down everything that enters the patient. Mark the reaction after each product. Go to the allergist with these notes.
