RHINITIS
⁃ Allergic rhinitis occurs when your body’s immune system over-responds to specific, non-infectious particles such as plant pollens, molds, dust mites, animal proteins, chemicals, foods, medicines, insect venom, and other triggers.
⁃ During an allergic attack, a special antibody (fighting protein), called IgE, attaches to cells that release histamine and other chemicals in the lungs, skin, and the mucous linings of the body.
⁃ These chemicals open the blood vessels and produce skin redness and swollen membranes.
⁃ When this happens in the nose, sneezing, itching, runny nose, and congestion occur.
