Tabeebak Qatar provides you with the best allergy clinics in Qatar . Allergies are your body's reaction to a substance it views as a harmful “invader.” For example, coming into contact with what is normally a harmless substance, such as pollen, might cause the immune system (the body's defense system) to react. Substances that cause these reactions are called allergens. An “allergic reaction” is way the body responds to the allergen. A chain of events occur that result in an allergic reaction. The first time an allergy-prone person is exposed to a specific allergen (such as pollen), the body responds by producing allergic (IgE) antibodies. The job of these antibodies is to find molecules of the offending substance in the bloodstream and tissues and to usher them to the body's mast cells (a type of white blood cell) for destruction. As the mast cells destroy the allergens, a chemical called histamine is released into the bloodstream. A large amount of histamine swells body tissues (inflammation), causes itching, enlarges blood vessels, increases secretions, and causes bronchospasm (tightening of muscles that surround the airways). what time you have to visit any of allergy clinics in Qatar, Mild reactions include local symptoms (affecting a specific area of the body) such as a rash orhives; itchiness, watery/red eyes, hay fever, and runny nose. Mild reactions do not spread to other parts of the body. Moderate reactions include symptoms that spread to other parts of the body. Symptoms may include itchiness, hives, and/or swelling, and trouble breathing.so, you have to visit any of allergy clinics in Qatar. A severe allergic reaction, known as anaphylaxis, is a rare, life-threatening emergency in which the body's response to the allergen is sudden and affects the whole body. Anaphylaxis may begin with severe itching of the eyes or face. Within minutes, more serious symptoms appear, including throat swelling (which could cause problems with swallowing and breathing); abdominal pain; cramps;vomiting; diarrhea; hives; and swelling (angioedema). The person may also have mental confusion or dizziness, since anaphylaxis may cause a drop in blood pressure.so, you have to visit allergy clinics in Qatar. Many allergens such as dust or pollen are airborne particles. In these cases, symptoms arise in areas in contact with air, such as eyes, nose, and lungs. For instance, allergic rhinitis, also known as hay fever, causes irritation of the nose, sneezing, itching, and redness of the eyes. Inhaled allergens can also lead to increased production of mucus in the lungs, shortness of breath, coughing, and wheezing. Aside from these ambient allergens, allergic reactions can result from foods, insect stings, and reactions to medications like aspirin and antibiotics such as penicillin. Symptoms of food allergy include abdominal pain, bloating, vomiting, diarrhea, itchy skin, and swelling of the skin during hives. Food allergies rarely cause respiratory (asthmatic) reactions, or rhinitis. Insect stings, food, antibiotics, and certain medicines may produce a systemic allergic response that is also called anaphylaxis; multiple organ systems can be affected, including the digestive system, the respiratory system, and the circulatory system.
