Can Someone Develop An Allergy To Latex Later In Life
Yes: It's hard to get latex allergy. Nurses develop eczema or contact dermatitis after using latex gloves for years. Later anaphylaxis, severe life-endangering form of allergy, occurs if latex contacts a mucosal surface - like a balloon in your mouth - or during surgery when the surgeon's gloves touches the inside of the body. Kids get it if they require multiple catheterizations for neurogenic bladder. ...Read moreSee 2 more doctor answers
Unknown: Many people (at least half) develop shellfish allergy later in life. This probably reflects the way the immune system develops, as some allergies are more common in very young children than adults (like egg), while others develop later (like pollen, and shellfish). The exact mechanism is still unknown though. ...Read moreSee 1 more doctor answer
Yes: Children which wear or require frequent elastic bandages, require latex catheters, use latex bottle nipples can frequently develop latex allergy. Also if they are handled by care takers who frequently use latex gloves, they are at greater risk of developing latex allergy. You should not use powdered gloves with corn starch. Inhaling the latex which has adsorbed to the powder also contributes. ...Read more
Mosquito Menace: Each of us possesses an immune reaction to the anticoagulant saliva of mosquitoes, some more than others. It is possible that a person with a mild, local cellular reaction could later develop a more systemic "anaphylactoid" reaction to a bite, however this is extremely rare. Unlike bee or wasp venom, mosquito saliva is not designed to kill or paralyze but designed to anticoagulate and dilate. ...Read more
Can someone touching something after eating shellfish cause someone who is allergic(swells in the throat) to have an reaction?
Unlikely: It would have to be ingested by the allergic individual. So theoretically yes but unlikely. ...Read more
Can you have a allergic reaction to crab 4 hours after eating it ? And would a late reaction be life threatening?
Unusual: Allergic reactions to food , except for red meat, usually occurs within 2 hours after ingestion. However I would urge you to see an allergist to get tested before you touch crab again. Usually the earlier the onset , the more severe the reaction. But delayed anaphylaxis (2-8 hrs later) can also be life-threatening. ...Read more
How do people overcome a food allergy that they had as a child? (I used to be allergic to shrimp).
Good question.: Many food allergies are "outgrown" presumably due to maturation of the gastrointestinal tract or the development of immune tolerance. A good example is that for milk-allergic people who can tolerate cooked milk products, the regular intake of cooked milk product may actually reduce the allergy to raw milk with time. As for shrimp, the chance of outgrowing is likely around 20% vs 95+% for milk. ...Read more
Yes/unrelated: People that are allergic to penicillin can be allergic to "fruit mold" but they are completely different reactions and are unrelated. The "fruit mold" that you are mentioning is probably pennicilium - the mold that actually makes penicillin. However, allergic reactions to those are separate and unrelated. ...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 because 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
Is it possible to develop an allergic reaction to a drug/antibiotic that you've never had an allergic reaction to in the past?
How can an allergic reaction become life threatening? What should I know if living with someone allergic?
Anaphylaxis: The most dangerous allergic reaction is anaphylaxis. With this type of reaction, the individual will develop a brisk systemic reaction (hives, swelling, breathing problems, passing out) that can rapidly progress and can cause death. The treatment is avoidance of trigger and use of injectable epinephrine. ...Read more
Type 4 immune diseas: We don't know why some people develop this type 4 immune disease. The formal name is delayed hypersensitivity. This is commonly called a rash from poison ivy or nickel. The disease process is the same. Only the cause is different. Certain compounds we are exposed to triggers a reaction by the immune system. ...Read more
Yes: It's not clear why, but a person can develop peanut allergy as a child, teen or adult. Even if a person has tolerated peanuts for years, a peanut allergy can develop. It's been found now that avoiding peanut in the diet of infants/children for the first few years will not prevent the development of peanut allergy. Something about "roasted" peanuts make them more allergenic than boiled or fried. ...Read more
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
