What are the reactions of histamine?
histamine reactions are a defense mechanism used by the immune system to protect the body from allergens. When the immune system comes into contact with the allergen, it sends chemical histamine. Histamine reactions may include nasal swelling, rashes and itchy eyes. The severity of the histamine reaction can range from moderate to heavy. Severe allergic reactions may require medical care.
When a foreign substance or allergen enters the body, the immune system induces the production of immunoglobulin E, also known as IgE antibodies. The antibody pairs with white blood cells in the bloodstream and rushes to a foreign substance. For example, if the allergen is inhaled by the nose, IgE and white blood cells will rush to the nose.
When GE and white blood cells reach allergens, ginie cells are warned to produce histamine. Histamine causes allergic symptoms such as sneezing, watery eyes and skin rashes. When too much histamine is released or if the body is sensitive to histamine, there may be a severe allergic reaction.
The effects of serious histamine reactions may include shortness of breath, strenuous breathing or swelling. In a small number of cases, severe histamine reactions may lead to anaphylaxis or anaphylactic shock. Anaphylactic shock is a combination of histamine reactions and pulmonary restrictions. The clamp and blood pressure breathing are impaired or impossible.
Anaphylactic shock may be life -threatening if medical treatment is not performed in a short time. Treatment of severe histamine reactions such as anaphylactic shock may include separate epinephrine shots. Epinephrine shots require a prescription. Not all histamine reactions will require medical care-in many cases, over-the-counter medicines or avoidance may be enough to treat mild symptoms.
histamine reaction may be triggered by environmental substances, animals and food. Common environmental allergens include dust, pollen and mold. ThreeAnimals that normally cause allergic reactions include dogs, cats and horses. Adults and children may also suffer from food allergies that cause histamine reactions. Peanuts, milk and strawberries are particularly concerned about children.
symptoms of histamine reactions may be seasonal or situational. Seasonal allergies include pollen and ragweed. Situational allergies may include allergies to animals or food. If the reaction of histamine to seasonal or situational allergies is serious, doctors can propose avoidance together with prescribing emergency drugs such as epinephrine. If a shot is used, the patient must be immediately transported to the hospital emergency room for medical assistance.
