The pollen reached by air in the nose, lungs and eyes. Therefore, the airway in hay fever sufferers particularly hard hit. Typical hay fever symptoms are:
Nose

* Runny nose and sobbing.
* Nasal congestion (swollen mucous membranes due to)
* Sneeze
* Itching

Eyes

* Red Eye
* Burning sensation
* Swollen eyelids
* Photosensitivity
* Itching

Further Hay fever Symptoms

* Opacity
* Quick tired
* The patient feels ill

Sometimes the patient also suffers from coughing or rustling in the ear.

Very clearly typical for people allergic to pollen that day, during the time that pollen will be released, will intensify the symptoms and the condition worsens. In bad weather and more prolonged rain, the patient usually feels better.
Hay fever diagnosis by the doctor

If you suspect allergic to, it is advisable to switch doctors. The best course is an allergist. The doctor can not only diagnose allergies, but also provide various investigations. These test results may cause the allergens (the substance for which one is allergic) can be identified. However, this does not always work, because with over twenty thousand different known allergens may also be that there is no clear diagnosis to give. Especially with food allergy is difficult.
Research on indentification of the allergen

Skin testing (prick test, intracutaantest, scratch test and friction test), small amounts of different allergens in different spots on the skin. Is the patient really allergic to one of these substances produces an allergic skin reaction (swelling, rash, red skin).

In blood tests the blood samples taken from the patient in response sensitivity and specific sensitization to the allergen tested examined.

Since a few years there is a imuuntherapie available in the form of tablets. These tablets are a preparation from pollen extract of timothy (Phleum pratense). If the tablet over a period of three years daily placed under the tongue (sublingual use), where the tablet dissolves and the release from allergens. In this variation of specific immunotherapy develops an immune resistance to the allergen, and reigns less sensitive to contact with pollen.

This specific immune therapy not only helps people who are allergic to timothy, but in general against allergies to grasses, and even roggepollenallergici have benefited. The reason is that all the sweet grasses from the same botanical family are. Ninety-five percent of all cereal grasses, and only three come from the same families. Botanically closely related eg rye, wheat and millet.

Hay fever, such as, asthma or neurodermatitis, a group of diseases that cause all the same in the body can be traced to. The cause is allergic to substances in the environment such as flower or grass pollen. These work as allergens and cause an immunological reaction. The tendency to such a reaction is what truly innate chin. Certain environmental factors can, however, the probability that a full allergy, increase. Fine dust is an example.

These sensitive individuals introduced the first contact with an allergen to the production of natural antibodies in the body, called anti-bodies. From that time the body recognizes ordinary daily occurring substances in the environment suddenly as dangerous. The body is allergic “to” put. Over time the body develops in contact with the allergen more antibodies, and finally comes when an allergic reaction Places the find. On contact with the allergen from then the body reacts to the allergen as a foreign body substance must fight, and one is really ill, for example, grass or flower pollen.

On contact with the allergen connect the anti-allergen and the bodies themselves, and forcing some cells to the emission of a substance transfer. An example is transfer substance histamine. Histamine is a biologically highly active substance that occurs throughout our bodies. The effect of histamine will be familiar to anyone who has ever touched a nettle. Histamine dilates small blood vessels. This creates a red rash. From blood vessels into the surrounding tissue fluid is included, and there arises a swelling. It is the activity of the glands increased.

If this inflammatory reaction in the nose occurs, one sees the typical symptoms of hay fever:

* Snotty, high moisture loss through the nose.
* Nasal congestion by swelling of the lining.
* Violent and frequent sneezing attacks, violent sneeze.
* Itching.

The eyes are affected by allergic reactions:

* Red eyes.
* Itchy eyes.
* Burning sensation.
* Sensitivity to light.
* Eyes watering.

There are many other complaints. Such a patient may be very different. Thus there itching in the ears and mouth occur, but also headache, fatigue, weariness and irritation occur.

In any event that this condition affects people strong, and strong symptoms the patient has great difficulty in his daily life as before to continue. The exercise of the profession and leisure activities can be similarly difficult.

Furthermore, in an untreated allergy after several years created new allergies. There may even arise allergic asthma.

* Antihistamines. Also called histamine receptor blockers. These are histamine fighters. The histamine is released from allergies, and leads to the typical hay fever symptoms. Antihistamines block the action of the body, and thus may suppress the symptoms. The more old-fashioned anti-histamine funds had the side effect of users fell ill with fatigue. Newer agents are not the problem, and can be used without problem. Another important effect of this anti-histamine funds is that they very rapidly effective, and the effect lasts several hours.
* Mestcelstabilisatoren as cromoglicic acid stabilizes the cell membrane of mast cells. These are the cells that contain histamine, and by the stabilization of emissions prevented histamine. Unlike antihistamines cromoglicic acid has only effect when used regularly throughout the season allergens (ie during the pollen flight). It may take several days before results are noticeable. Therefore at least two to three weeks before the pollen flight started with this treatment.
* Swelling Inhibitory nasal sprays that constrict blood vessels of the nasal mucosa. These funds also called vasoconstrictors known, and can be used for allergy and cold symptoms related burning eyes and itchy eyes. It is important that these funds not more than two to three weeks successively used. Doing that, can prevent damage to the nasal mucosa.
* Cortisone nasal sprays, are not only heavy and antihistamine used to control symptoms. Cortisone is an endogenous hormone that suppresses the immune system, and thus allergic symptoms. During brief periods of applied force usually no complications. With prolonged use can have side effects such as hypertension or create acne. The systemic cortisone therapy should remain exceptional and should only be prescribed by a doctor.

While hay fever may not sounding serious, take this condition seriously! Avoid allergens, and follow the instructions of your doctor. Take your hay fever medication regularly.

Food allergens
Before having a food allergy reaction, a sensitive person must be exposed to food at least once before. Allergic symptoms occur the second time the person eats the food. This time, when IgE antibodies react with the food, histamines are released, causing hives, itching in the mouth, difficulty breathing, stomach pain, vomiting or diarrhea.

The difference between food allergy and food intolerance
Food allergy causes an immune system response, causing symptoms ranging from uncomfortable to life threatening. Food intolerance does not cause immune response, although some symptoms may be the same as in food allergy.

The most common foods causing food allergies
Approximately 90 percent of all food allergies are caused by eight foods:

* Milk.
* Eggs.
* Wheat.
* Soya.
* Nuts.
* Fish.
* Seafood.
* Mani.

Eggs, milk and peanuts are the most common causes of food allergies in children, also including wheat, soybeans and nuts. Peanuts, tree nuts, fish and shellfish commonly cause the most severe reactions. About 6 percent to 8 percent of children have food allergies. Although most children “outgrow” their allergies, allergy to peanuts and tree nuts may be life.

Food allergy symptoms
Allergic symptoms may begin within minutes to an hour after ingesting the food. The following are the most common symptoms of food allergy. However, each individual may experience symptoms differently. Symptoms may include:

* Vomiting.
* Diarrhea.
* Cramps.
* Hives.
* Bloating.
* Eczema.
* Itching or swelling of lips, tongue or mouth.
* Itching or tightness in the throat.
* Shortness of breath.
* Wheezing.
* Low blood pressure.

According to the National Institute for Allergy and Infectious Diseases (National Institute of Allergy and Infectious Disease), does not need much quantity of food to cause a severe reaction in highly allergic people. In fact, as little as 1/44.000 of a peanut kernel can cause an allergic reaction in individuals with severe allergies.

Symptoms of food allergy may resemble other conditions or medical problems. Always consult your physician for diagnosis.

Definition

Stuffy or runny nose, sneezing, itching in the palate, eyes red and stinging. This is not necessarily a “common cold” but may be of allergic rhinitis.

Allergic rhinitis is characterized by inflammation of the nasal mucosa.

It is manifested by a set of symptoms (sneezing, nasal discharge and obstruction) due to an excessive immunological reaction in the presence of a foreign substance is called an allergen. Allergens are natural components of the environment such as pollen or cat hair, but the immune system of a person sensitive (or allergic) responds inappropriately.

Allergic rhinitis may be associated with asthma, allergic conjunctivitis and other diseases such as sinusitis or otitis.

Traditionally, allergic rhinitis were distinguished into two entities:

* Seasonal allergic rhinitis or “hay fever” or pollinosis, easily identifiable as occurring each year in the same season and most often associated with conjunctivitis. Seizures occur when the arrival of pollen, when their concentration in the air increases.
* Allergic rhinitis “perennial” that lasts all year and is often associated with asthma. The allergens are usually mites (house dust), animal dander (especially cats), mold and cockroaches.

Classification of rhinitis

Allergic rhinitis is classified according to frequency of symptoms and their severity and impact on quality of life of patients:

* The time factor
Rhinitis is considered intermittent when symptoms are present less than four days per week or less than four weeks per year. She was diagnosed as persistent when symptoms are present, rather more than four days per week over four consecutive weeks per year.
* The severity factors
Rhinitis is slight if the patient does not feel any of the following symptoms: sleep disturbance, impact on daily activities, sports, business or school, disabling symptoms.
Conversely, rhinitis is moderate to severe when the patient suffers from at least one of the problems cited above.

Mechanism of allergic reaction

Allergic rhinitis is characterized by an abnormal reaction of the nasal mucosa to an allergen. These allergens generate inflammation responsible for clinical symptoms of rhinitis. It is an allergic reaction.

The mechanism of the allergic reaction is a complex phenomenon that consists of 2 phases:

* 1. Awareness
This phase called awareness begins when the individual enters for the first time in contact with the allergen. The allergen is then considered by the immune system as a hazardous substance. He is captured by a macrophage (cell host defense); The latter communicates with cells that will secrete antibodies (IgE) specific to the allergen. These IgE antibodies attach themselves to mast cells and are subsequently able to recognize the allergen.
* 2. Phase 2: The reaction in allergic rhinitis
When the allergen enters the body again, it is recognized by IgE present on mast cells while in the nasal mucosa. The IgE will then defend the body against the allergen and trigger a chain reaction – which results in clinical manifestations of allergy: runny nose, itching eyes, etc.
