Spring Allergy or Seasonal Allergic Rhinitis
Allergy is physical symptom caused by oversensitivity of the immune system to some allergens (substances or strange bodies) that enter the body. Allergens are not necessarily harmful, but the immune system defines it as such and thus develops its antibodies (lge) These substances trigger the immune system to secrete antibodies in order to protect the body. When antibodies define a certain substance as an allergen, a series of chemical procedures that happen activate the mast cells. These cells release a wide group of chemical substances including histamine that causes allergic reactions. Allergic reactions may occur immediately or after a while.
The immediate reaction might be mild and transient and can be severe and dangerous such as an anaphylactic shock that happens a short time after exposure to the allergen.
However, there is a delayed allergic reaction and it is the most common type of allergy. It normally occurs hours and even days after exposure to the allergen, therefore it is normally difficult to identify.
Seasonal Allergy – Spring Allergy:
Allergic rhinitis is an antigen-mediated inflammation of the nasal mucosa that may extend into the Para nasal sinuses. It is caused by allergic reactions to airborne substances such as pollen, but there are other causes for Seasonal allergy as well.
The immune system produces antibodies in order to protect the body. These antibodies collide with the allergens and cause a kind of trauma to the body that results in inflammations of the nasal mucus membrane. This inflammation causes swelling as well as obstruction of the respiratory tract. It also causes over activity of the gland that secrete mucus and phlegm so it looks similar to running nose.
