10 symptoms indicative of an allergy

Allergy occurs when the body exposes itself to the allergenic component, whether it is internal (ingestion), dermal (skin contact) or respiratory (inhalation). The symptoms of allergies are various and varied. Below are the ten tell-tale symptoms of an allergy.


Urticaria is an allergy of the skin that is characterized by the appearance of itching and the appearance of red flat or raised bumps. The duration varies between a few minutes to several hours. Urticaria is often not serious. The situation begins to be disturbing when it touches the deep tissues and causes them to swell. This skin disease is very common. Between 15% and 20% of people experience at least one urticaria outbreak during their lifetime, according to the WHO. In its acute form, urticaria affects children.


Eczema is a skin condition that causes severe itching, most commonly in the hands, ankles, elbows and knees. Eczema can begin very early in life, even in babies. The factors that cause eczema are many, including nickel, cosmetics, or detergents and softeners.


Rhinitis is an inflammation of the nasal cavity that results in persistent nasal discharge, swelling of the mucous membrane, sneezing and tingling. This is one of the symptoms of food allergy. It is mainly due to grass pollen. Rhinitis also occurs in case of allergy to mites, animals and mold. It affects both children and adults.


Often of allergic origin, asthma is an inflammatory and chronic disease of the respiratory tract. It results in breathing difficulties, coughing fits and chest tightness and difficulty breathing. Asthma affects all age groups, young and old, and is frequently associated with allergic rhinitis.


Conjunctivitis is a common eye disorder. It is an inflammation of the connective membrane, a transparent mucous membrane covering the white of the eye and the inside of the eyelids. It is reflected in particular by the redness of one or both eyes. Conjunctivitis is due in particular to allergens present in the atmosphere (mites, animal hair, feathers, pollen ...).


Diarrhea is not a disease but rather a symptom. This is a common, often non-serious problem that is characterized by loose stools of liquid or soft consistency. Diarrhea can be caused by intolerance to a food and its possible symptoms appearing after consumption.


Vomiting is a very common symptom of food allergy. It allows the body to get rid of the residue of gastric contents. Vomiting is often accompanied by diarrhea and / or gastric pain.


Gastroesophageal reflux (heartburn) is an allergic reaction related to the digestive process. It is most often manifested by burning with epigastric pain when gastric juice produced by the stomach (acid) passes the gastroesophageal junction (cardia) and back into the esophagus, sometimes to the mouth. Gastroesophageal reflux is due in particular to intolerance to cow's milk proteins.


Quincke's edema is a violent allergic manifestation that is characterized by a marked swelling, localized on the face, eyelids and lips. Quincke's edema is most often a sign of intolerance to a food or medicine. It can also occur because of a bite of insects (wasps, bees, hornets).


Anaphylactic shock is an allergic reaction that results in general malaise, sudden acceleration of heart rate, difficulty breathing, and loss of consciousness. It represents the sign of ingestion of allergenic foods, following an insect bite, taking analgesics, iodine derivatives or certain antibiotics. It is an absolute vital emergency that requires an adrenaline injection. It can even lead to death.
