Morel Mushrooms And Allergic Reaction
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
An altered reaction: The roots of "allergy" are from greek "allos" (different) and "ergos" (action). So, an allergic reaction is a "different" (from normal) reaction. The reaction occurs to an allergen. An allergen can be a pollen (ragweed), food (peanut), animal (dust mite or bee venom), or other foreign substances. Symptoms occur due to histamine and other chemicals and cause sneezing, runny nose, etc. ...Read moreSee 2 more doctor answers
Allergic Reaction?: Not sure what you mean by allergic reaction. If you are referring to anaphylaxis then epinephrine is the treatment of choice, call 911. Allergic rhinitis is treated with OTC antihistamines, daily intranasal steroid or antihistamine sprays, saline rinses, etc. Allergy shots also an option. Avoidance of triggers is important but see an Allergist first to determine exactly what you are allergic to. ...Read more
Why allergists exist: Finding & treating the cause of allergic reactions is the main function of an allergist. A solid understanding of the immune system is required, so that immunology goes hand in hand. Timing, prevalence of various causes, location, description, examination, associated factors, family history and finally testing enables allergists to identify the culprit, if one is present; treatment is pt-centered. ...Read more
Benadryl (diphenhydramine): Immediately stop eating the food you think is causing the problem. Take liquid or dissolving Diphenhydramine (benadryl). If your reaction is worse: cough, shortness of breath, wheezing, chest tightness, difficulty breathing, hives all over your body, swelling of lips and tongue, etc., then you need to use your Epinephrine autoinjector (epipen, twinject) and go to the nearest emergency room. ...Read moreSee 1 more doctor answer
Yes.: The nature of allergy is that repeat exposure results in repeat, and often more exaggerated, response. There is always the question of whether the initial reaction was true allergy or something else like irritant response or drug side effect. Another important aspect of allergy is "cross-reactivity", which occurs when similarly structured molecules (eg drugs in the same family) are recognized. ...Read more
Inflammatory rxn: An allergic reaction is the body's defense against an agent it considers harmful or toxic to the body. Most allergic reactions start with food allergies that are undiagnosed and "rev up" the immune system leading to multiple other reactions to environmental items as in mcs. First firgure out what's wrong with the gut and fix it and the immune system will settle down and others will lessen/go away. ...Read more
Often to nickel: The skin can get red itchy and bumpy...Stop wearing it and if not severe (or infected) try cortisone cream (not benadryl) and avoid the jewelry. If it happens with several pieces, bring them to an allergist with a description of the reaction (and maybe picures). The testing can often be done. ...Read more
Allergic reactions often causes itching but the symptoms are greatly organ-dependent.
*Nose- congestion, runny nose, sneezing
*Eyes- itching, redness, tearing
*chest-wheezing, shortness of breath, and coughing.
Other conditions include hives from food, itchy mouth and throat from certain fruits, and rarely anaphylaxis.
Contact skin allergy is yet another but the mechanism is different. ...Read more
Allergic reaction: .. is an inappropriate immune response to a trigger, or allergen (eg pollen). The body forms immunity to something it recognizes as foreign, but also "overreacts" to it. Some reactions occur quickly if mediated by antibodies bound to white blood cells called mast cells or basophils (eg peanut allergy) or they occur slowly if mediated by T-cell (eg poison ivy). Less common mechanisms also exist. ...Read more
Immunologic: An allergic reaction is the body's immunologic response to a substance (typically a protein) that it determines is "foreign." the body's th2 type of t cells interacts with b cells that produce ige antibodies. When ige antibodies that are present on mast cells subsequently encounter the allergen, the mast cell releases histamine and other chemical mediators that lead to the symptoms of allergy. ...Read moreSee 1 more doctor answer
