Allergic Rhinitis, Hay Fever and Perennial Allergic Rhinitis: Advice
Good advice
- If hay fever is caused by pollen, try to keep doors and windows closed during the pollination season. Especially when driving.
- Know the stage of pollination pollen are allergic to, see the levels of pollen provided by health services in your community.
- If you suffer from allergic rhinitis, house dust mites, cover the mattress with allergy covers, vacuum and ventilate the room.
Possible complications
Patients with allergic rhinitis are more vulnerable to:
- Other allergic respiratory diseases like asthma.
- Difficulties in sleep can lead to chronic fatigue.
- Otitis, especially in children. Continue reading
Allergic Rhinitis, Hay Fever and Perennial Allergic Rhinitis
What is allergic rhinitis?
Allergic rhinitis is an allergic reaction to airborne substances (allergens) that attacks the upper respiratory tract: nose, sinuses, throat, and often in the eyes (rhinoconjunctivitis). May be of hay fever (also called seasonal allergic rhinitis or hay fever) when caused by pollen, or perennial allergic rhinitis type if it is caused by allergens such as house dust mites and pets.
It is the most common allergic disease: 15% of the population in industrialized countries suffering from allergic rhinoconjunctivitis. Symptoms usually first appear in childhood or young adulthood, and are relieved at 30 to 40 years.
The name hay fever, of ancient origin, is misleading because symptoms do not occur only in autumn when hay is traditionally collected, and never include fever. Continue reading
Allergic Disease: What are Allergens?
What are allergens?
Allergens are substances of protein nature that act as foreign agents for the body and are capable of inducing an immune response that leads to the synthesis and release of antibodies that interact both definitive cause allergic reaction. Substances that can cause this type of reaction are:
- Pollen of plants, flowers and trees shrubs and weeds
- Molds and yeasts
- House dust mites and storage sites
- Poison insects: bees, wasps
- Other insects: cockroaches, mosquitoes
- Epithelium of animals: cat, dog, horse, rabbit, hamster, mouse
- Bird Feathers
- Drugs and diagnostic substances
- Cosmetics Continue reading
Allergic Disease: What is Allergy?
Allergy, or type 1 hypersensitivity, is a pathophysiological response of the body against substances of protein nature that act as foreign antigens against which the immune system promotes the production of antibodies from prior exposure.
If an allergic person is exposed to foreign substances, called allergens, or allergens, the different cells that make up the immune system running a series of biological mechanisms aimed at producing antibodies to fight them.
White blood cells called B-lymphocytes are responsible for the production of antibodies. These are attached to the surface of cells mediate the allergic reaction. The body is prepared in this way to combat foreign allergens in a forthcoming exhibition. This first process-recognition of a foreign substance and presentation to the immune system to develop a first synthesis of antibodies, is called sensitization. Continue reading
