Gastric gas can cause stroke



The allergic conjunctivitis (conjunctivitis) can occur in many allergic diseases such as pollen, mite or mold allergy. It manifests itself through typical symptoms such as itchy, reddened eyes and increased tearing. Swelling of the eyelids is also possible.


At a allergic rhinitis (rhinitis), the nasal mucous membrane becomes inflamed through contact with allergens. Typical complaints are itching, seizure-like sneezing attacks and a blocked or runny nose. Depending on the allergens, the symptoms can occur seasonally (pollen allergy) or all year round (mite and mold allergy). Pollen allergy sufferers often suffer from itching and runny nose with seizure-like sneezing attacks, while mite allergy sufferers mainly report a stuffy nose after getting up.

Often, allergic rhinitis and allergic conjunctivitis occur at the same time. Experts then speak of rhinoconjunctivitis.

respiratory tract

People who suffer from allergic rhinitis are at risk of so-called "Change of floor“The allergic disease. The allergic rhinitis (disease of the upper respiratory tract) develops over time allergic bronchial asthma (Lower respiratory disease).

In asthma, the airways are permanently inflamed. The bronchi are sensitive to actually harmless stimuli such as cold air (bronchial hyperreactivity) and the airways can also be narrowed (variable airway obstruction).

Asthma occurs in around 10% of children and 5% of adults in Germany and can have various causes. Allergies are the most common cause of asthma in childhood and adolescence. In adults, 50-70% of asthma illnesses are caused by an allergy.

In addition to pollen, mites and mold, food can also trigger allergic asthma.


One of the most common allergic skin diseases is this atopic eczema. The inflammatory skin disease is also called atopic or dermatitis Eczema designated. The main symptoms of eczema are Skin dryness and a severe itching. If the inflammation is severe, infections of the skin with bacteria or fungi can also occur. Atopic dermatitis patients are often allergic to house dust mites, cats, pollen or food. The disease affects 2-5% of the German population and usually begins in childhood.

People who are allergic to pollen, mites, mold and also food allergies sometimes suffer from itching and reddening of the skin as well as rashes (hives).

Gastrointestinal tract (gastrointestinal tract)

Allergic gastrointestinal diseases are the result of excessive reactions of the immune system to actually harmless foods. This can cause various complaints in the gastrointestinal tract such as Flatulence, pain or diarrhea, to be triggered. 2-3% of adults in Central Europe are affected by a food allergy. 4% of young children have a confirmed food allergy. Allergic gastrointestinal diseases can significantly impair the patient's performance. Gastrointestinal complaints are often difficult to identify and years can pass before the correct diagnosis is made. In the case of unclear gastrointestinal complaints, an exact allergy diagnosis is therefore essential.

The consumption of certain foods can also lead to an oral allergy syndrome with swelling of the tongue, lips and larynx area (up to breathlessness) and itching of the mouth and throat. The person affected may be directly allergic to the food (e.g. to cow's milk, hen's eggs, peanuts, fish) or suffer from a pollen-associated food allergy (e.g. apple, cherry). In the second form, the allergens in the food are similar to the allergens in pollen and trigger symptoms in people who are allergic to pollen.

Central nervesystem

Non-specific complaints such as weakness, tiredness, headaches, sleep disorders and fatigue can also be triggered by allergic reactions to pollen, mites, mold and food.

Patients with unclear symptoms should therefore have a specialist clarify whether their symptoms are caused by an allergic reaction.

In the immediate allergic reaction (Anaphylaxis), an acute reaction of the entire organism occurs immediately after contact with the allergen. An immediate allergic reaction is mainly triggered by bee or wasp poisons, but also foods or drugs (e.g. X-ray contrast media, acetylsalicylic acid, penicillin). Epidemiological studies estimate that 1-15 % of the German population are affected. In severe cases, an immediate allergic reaction can lead to death. Patients who have ever had an anaphylactic reaction are therefore given emergency medication for self-treatment by their doctor.
