allergy symptoms

       Common symptoms of allergy




A person may experience common symptoms every day, which in reality are caused by the allergy. Even more serious conditions, such as asthma attacks, can be caused by an allergy triggering factor. Below are presented various typical symptoms that often constitute an allergy signal.

Eczema | Hay fever | Ocular inflammation Gastrointestinal disorders Urticaria | Allergic oral syndrome (OAS) Asthma | Anaphylactic reactions

Allergy symptoms vary in complexity, severity and manifestation. In atopic allergies, the effect of exposure to an allergen may be immediate. Symptoms may be mild or severe and may range from ocular pruritus to eczema and rhinitis, conjunctivitis, bronchoconstriction, vomiting, and diarrhea, and in rare cases to anaphylaxis.
Chronic reactivity

Reactivity such as skin reactions (eczema) or asthma attacks can be caused by allergy. For example, an ongoing inflammation of lung tissue may be the reason for an asthma attack found after exposure to the offensive allergen. Asthma attacks can also be caused by events other than IgE-mediated reactions.
The events may vary

The manifestations of atopic disease vary considerably depending on the allergen involved, as well as the age of the allergic person. During childhood, food allergies (especially egg and milk) are the most common. After 3 years of age, most of the allergic children tolerate such foods, while the allergy to inhalants becomes predominant. Specific IgE antibodies often precede allergy symptoms, but clinical symptoms reach them over time.

To learn more about specific allergic symptoms:
Eczema
Symptoms

    dry skin
    skin itching
    urticaria
    rash

Common trigger factors (allergens)

    food (eg eggs, milk, fish, wheat, peanuts, soybeans and hazelnuts)
    house dust mites
    pets (eg cats, dogs, guinea pigs, rabbits)

Why do these symptoms occur?

Eczema can occur in combination with allergen exposure. It can also increase sensitivity to trigger factors, as the natural skin barrier is damaged. Eczema in children has also been linked to an increased risk of developing rhinitis (eg hay fever) or asthma in adulthood.
Eczema in short

Eczema is a condition that affects both children and adults. In most cases it manifests itself in early childhood. In young children, eczema will often occur on the cheeks, torso and / or joints of the arms and legs.

There is no cure for eczema, but it is important to use a lotion. It is also important to investigate the cause of the eczema. With a clear diagnosis and good doctor's advice, the patient will be better prepared to face and overcome some of the most unpleasant effects.
Hay fever (allergic rhinitis)
Symptoms

    closed nose
    breath only from the mouth
    itchy nose
    throat / mouth / lips itching
    ocular itching and redness, swollen eyelids
    a runny nose
    sneezing
    swelling of the mouth / respiratory tract
    ocular lacrimation

Common trigger factors (allergens)

    pollens (eg plants, weeds and grasses)
    house dust mites
    cockroaches
    pets (eg cats, dogs, guinea pigs, rabbits)
    other animals (eg horses and birds)





       Why do these symptoms occur?

 Hay fever (allergic rhinitis) occurs when airborne allergens cause inflammation that triggers the production of fluids in the nose, cavity and eyes. Rhinitis is often seasonal (that is, it occurs during the pollen seasons) but it can also be perennial and persist throughout the year. Hay fever in short Hay fever or allergic rhinitis is an extremely common disease that is often mistaken for a common cold. However, rhinitis can develop into more severe disorders, such as asthma. Recurrent or prolonged symptoms must always be investigated. Ocular inflammation Symptoms

   ocular itching and redness, swollen eyelids

   ocular lacrimation Common trigger factors (allergens)

  pollens (eg plants, weeds and grasses)

   house dust mites

 cockroaches

  pets (eg cats, dogs, guinea pigs, rabbits)

     other animals (eg horses and birds) Why do these symptoms occur? Ocular inflammation combined with hay fever or allergic rhinitis is often seasonal (ie it occurs during the pollen seasons) but it can also be perennial and persist throughout the year. Eye inflammation in short Conjunctivitis is an inflammation of the outer layer of eyeballs that may occur as a result of exposure to allergens or due to a cold infection. Ocular inflammation or conjunctivitis often occurs in combination with hay fever (allergic rhinitis). Gastrointestinal disorders Symptoms

  diarrhea

 stomach pain

   nausea and vomit

   weight loss Common trigger factors (allergens) Infants and young children (0-3 years)     eggs

    milk
   wheat
     soya beans Children and adults

  eggs
   milk
   shellfish
 wheat
     peanuts
   hazelnuts and other dried fruit
     fruits and vegetables Why do these symptoms occur?

 Symptoms are closely associated with food intake. However, it may be difficult to make a correct diagnosis, as there are many possible causes of gastrointestinal disorders such as allergy, celiac disease or lactose intolerance. Gastrointestinal disorders in short Allergy can cause stomach / intestinal disorders such as pain, diarrhea and vomiting in both adults and children, even from the first year of age. Urticaria Symptoms
  urticaria
  rash Common allergens
 nuts
   shellfish
   eggs
  milk Why do these symptoms occur? Urticaria could be both allergic and non-allergic and is very common. Allergy is one of the most common causes of urticaria in children compared to adults. In addition to allergy to foods or other substances such as drugs, hives can be triggered by a direct physical stimulus such as extreme temperatures, water, sun and exercise. Viral infections and stress can also cause an attack of hives. Hives in short



        Urticaria consists of pink localized, pale swallows (swollen), which can be pricked and can burn or sting. They can occur individually or in groups on any part of the skin. In most cases, the urticaria quickly disappears in the space of a few days / weeks. Allergic oral syndrome (OAS) Symptoms

  throat itching

 itching in the mouth

  itchy to the lips Common trigger factors (allergens)

   fruit (eg apples, pears, cherries, peaches, plums, apricots, kiwis)

   vegetables (eg carrots, raw potatoes, celery)

     legumes and hazelnuts (eg peanuts, cashews, walnuts and almonds, peanuts, soybeans) Why do these symptoms occur? Allergic oral syndrome (OAS) can occur in people allergic to pollen when eating certain fruits, vegetables, hazelnuts or beans. The symptoms appear due to the fact that the pollens contain proteins of structure similar to those present in this particular food. It is a cross reaction. As a consequence, the OAS is not a separate food allergy, but rather represents the cross-reactivity between pollens and certain fruits and vegetables. It is generally limited only to the ingestion of uncooked fruits and vegetables. Allergic oral syndrome at a glance Allergic oral syndrome (OAS) is common among pollen-allergic patients. It is usually a temporary and relatively mild condition, characterized by swelling, redness and itching of the area around the mouth. Eyes are also occasionally affected. Asthma Symptoms

    cough
lack of breath
dyspnea and wheezing Common trigger factors (allergens)     pollens (eg plants, weeds and grasses)
  house dust mites
 cockroaches
 pets (eg cats and dogs)
 other animals (eg horses and birds)
food Why do these symptoms occur? Asthma symptoms occur in conjunction with allergen exposure, exercise, cold air, dry air and in combination with respiratory infections. Other irritants (such as strong perfumes or cigarette smoke) can also trigger an asthmatic reaction. Asthma in short Asthma is defined as a persistent wheezing breath, often accompanied by wheezing, shortness of breath and cough, especially at night and upon awakening. It is the most common chronic disease in early childhood, often triggered by allergy. Anaphylactic reactions Symptoms Mild early symptoms may include:
    urticaria
  tingling and itching around the mouth
 swelling around eyes and mouth Severe symptoms may include:
 itching, especially on the soles of the feet, the palms of the hands or the scalp
    tingling in the mouth
 swelling in the mouth and throat
 hypotension
abdominal pain
 nausea and vomit
lack of breath
asthma symptoms
  a worsening of the general condition Anaphylaxis is a reaction that affects various organs of the body, one or more at a time. Although symptoms can be perceived as mild at first, there is a risk that they will quickly turn into a potentially lethal threat; therefore, rapid treatment is very important. The situation is urgent if the person loses knowledge. Common trigger factors (allergens)
  peanuts
dried fruit (eg hazelnuts, walnuts, Brazil nuts and cashew nuts)
    fish
  soya beans
 seafood
milk
eggs
seeds
 fruit
 drugs
bee venom and wasp Other foods can also trigger severe reactions, depending on local eating habits. The anaphylactic reaction in short




Other foods can also trigger severe reactions, depending on local eating habits.
The anaphylactic reaction in short

Anaphylactic reaction is also known as anaphylactic shock and is a potentially life-threatening acute allergic reaction. In general, the reaction occurs rapidly within 5-15 minutes and requires immediate treatment.

Food-related anaphylaxis can be triggered when exercise is combined with food intake to which the person is allergic.
