Allergic Reaction To Beets
Not sure if its an allergic reaction or my recent sunburn but skin around my mouth and chin is beet red after peeling two weeks ago! What can I do?
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 more
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 more
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 more
Drug reactions: The most common drug allergic reactions are to antibiotics like penicillin and sulfa. The second most common drug allergic reactions are Aspirin and nsaids such as ibuprofen. It is also very common for narcotics (morphine, codeine, demerol, (meperidine hydrochloride) etc) to cause itching and hives. ...Read more
(a)Caused by IgE (circulating antibodies against the allergen) leading to inflammation
Conditions: hay fever, asthma, eczema, food allergies, acute hives, allergic conjunctivitis, itchy throat.
(b)Caused by cells- contact dermatitis (poison ivy)
There are many other conditions which cannot be covered by this type of conversation. ...Read more
IgE antibody: When the body is exposed to an allergen (once or more likely many times), the body can respond by making the antibody ige. On re-exposure, the ige that is attached to mast cells present in the nose, skin, and lungs, degranulates and releases chemical mediators like histamine that leads to the symptoms of an allergic reaction like sneezing, itching, congestion, and swelling. ...Read more
Depends on severity: Severe allergic reactions (like anaphylaxis) that involve chest/throat symptoms are treated with Epinephrine for immediate relief and oral steroids. Milder allergic reactions that affect skin, nose, eyes are usually treated with antihistamines. The real goal is to identify the trigger, so it can be avoided. An allergist is uniquely trained to diagnose and appropriately treat allergic reactions. ...Read more
Possible: Latex allergy definitely occurs. People with latex allergy often get rash, itching, or swelling at sites of latex contact like the hands after wearing gloves or the genitals after use of a latex condom. Sometimes lip and mouth reactions can occur with balloons. People can also have reactions to the powder in powdered latex gloves that may carry latex particles. ...Read more
Look for signs: Though s/he can't tell you in words, watch for signs of itching: rubbing her cheeks into your neck or shoulder, crankiness, fussiness and crying without an obvious source. Redness, hives, rashes. Look for puffiness of the face, eyelids, cheeks. Food allergy may trigger vomiting, coughing, and wheezing. If s/he becomes lethargic, or floppy - do not delay: call 911. ...Read more
Symptoms: If the allergy is to a food or ingested medication, the typical symptoms are vomiting, diarrhea and rash (hives, itching). If trigger was airborne like pollen or pet dander, then itching (nose, skin, eyes), sneezing, runny nose and cough. Asthma symptoms can be from an allergy. An allergist can assist in identifying is symptoms are from an allergy and determine specifically which allergen. ...Read more
Often delayed rxn: Foods must generally first be digested, then absorbed into the body so reactions to them are usually delayed and are igg reactions. One often thinks of the peanut allergy that is immediate and deadly which is and ige reaction. The reactions can vary from diarrhea to constipation, skin rashes, joint pains, hair loss and more so testing with a specialty igg blood test is required to "figure it out". ...Read more
Vague question: But allergic reaction is usually but not always associated with itching and the external surface of the body including the skin, gut, lung, nose. When severe, it can be life-threatening (anaphylaxis). If you need more information, you will need to ask more specific questions. ...Read more
Medicines: It depends on the symptoms and the severity of the reaction. Severe reactions require immediate treatment. Mild reactions may respond to over the counter allergy medicines. Avoiding the trigger is also important. See an allergist for continuing or recurrent problems. ...Read more
After someone has an allergic reaction the most prudent step is to try, as hard as it might be at times, to identify the allergic trigger and avoid future exposure.
If you were referring to treatment after an allergic reaction it depends on the degree of response ie mild, moderate or severe. An allergist can help you answer these questions often just by taking an in depth history. ...Read more
See Allergist: An allergist is specifically trained and uniquely qualified to identify the causes of allergic reactions. The process includes a detailed history of exposures including timing, an examination, and frequently allergy testing. Allergists love solving these allergy puzzles! ...Read more
Usually fast: Most common allergic reactions to pollen, insect stings, foods, etc., are immediate hypersensitivity reactions, meaning they occur within seconds to minutes. But you can also have a late phase, a second-wave of reaction that occurs hours later. Contact allergies (poison ivy, nickel allergy, e.g.) and some medication allergies are delayed, and may take hours, days, or weeks. ...Read more
Latex Allergy: Typically patients with latex allergy develop localized redness, rash, and itching around the areas that was exposed to latex. This typically occurs after wearing latex gloves or latex condoms. Latex allergy is less common then it used to be causes most products these days are made latex-free. An allergist can do testing in the office to determine if you have a sensitivity. ...Read more
See an allergist: An allergist is specialty trained and uniquely qualified to assess and treat severe allergic reactions. Even if the cause is not currently known, an allergist can assist in finding the cause and preventing another reaction. ...Read more
Allergic reactions: Minor allergic reactions are generally improved with oral antihistamines with out without topical steroids. Severe allergic reactions characterized by facial swelling, respiratory distress, severe vomiting and swallowing problems should be treated immediately in the emergency room or with injected epinephrine. ...Read more
Depends: The most important issue that determines how long it lasts is whether or not you have stopped contact with the allergen. Once you stop touching it, things should look better every day. But I would say that it should be resolved within a week to 10 days. (think of poison ivy...A common topical allergic reaction.). ...Read more
