An allergy is a hypersensitivity disorder of the immune system. Allergic reactions occur when a person’s immune system reacts to normally harmless substances in the environment. A substance that causes a reaction is called an allergen. These reactions are acquired, predictable, and rapid. Allergy is one of four forms of hypersensitivity and is formally called type I (or immediate) hypersensitivity. Allergic reactions are distinctive because of excessive activation of certain white blood cells called mast cells and basophils by a type of antibody called Immunoglobulin E (IgE). This reaction results in an inflammatory response which can range from uncomfortable to dangerous.
How do you get allergies? Scientists think both genes and the environment have something to do with it. Normally, your immune system fights germs. It is your body’s defense system. In most allergic reactions, however, it is responding to a false alarm.
The picture is from a 22 year old male who has used over 1 can per day of snuff for the past 15 years. He has high blood pressure from the vasoconstrictive (contraction of blood vessels) effect of nicotine and gastroesphageal reflux disease (stomach acid coming up from the stomach towards the mouth) which is also made worse from using tobacco products. The picture shows extensive leukoplakia forming between his gums and lips. This is a pre-cancerous condition and if it does not resolve with his cessation of using tobacco products, it will need to be surgically removed.
