Doctor insights on: Pineapple Allergy Symptoms

Typical symptoms: Food allergy usually starts within 30 min. And involves some or all of following: itchy/swollen lips/mouth/throat, nausea, vomitting, abdominal cramps, diarrhea, flushing, itchy skin, hives, chest tightness, wheezing, runny/stuffy nose, itchy/watery eyes, lightheadedness/low bp. It is rare to have a single symptom except itchy mouth and symptoms resolve within 24 hours.

See Allergist: Food allergies are typically an immediate reaction minutes to a half hour after ingestion of concerning food with symptoms ranging anywhere from hives, wheezing, itching, shortness of breath, wheezing, vomiting, or syncope (fainting). If this sounds familiar or you are concerned see an Allergist for skin or blood testing to sort things out.

Avoidance: In general the treatment of a food allergy is avoidance of the offending allergen. However Some fruit allergies are due to cross reacting pollen allergens. In this case people may tolerate the fruit if peeled or cooked.

Avoidance: Like any food allergy, avoidance will be the answer. But before you do that, if you are not sure you have it, talk to an allergist. Keep in mind that the current testing options (blood and skin test) are not perfect; they can overdiagnose and underdiagnose food allergy.

Food allergy: Allergy to any food, in this case pineapple will cause symptoms of oral itching, lip or tongue swelling, hives, breathing difficulty and/or throat closure etc. Food allergy is diagnosed with clinical history followed by skin or blood test and that information helps establish the diagnosis and severity of the allergy.

Few hours: If the rash (usually hives) doesn't resolve within a few hours of staying away from pineapples, it probably has another cause.

Epi: They usually last a year but need to check expiration date on device itself. Keep out of extreme temperatures (do not leave in hot car, freezer, etc)

Not an allergy: Diarrhea is not an allergic reaction. In all probability the pineapple (or something else you ate) was not cleaned properly, and you swallowed some bacteria that caused the diarrhea.

Not usually: Although some fruits share common allergens (melon/banana, avocado/banana), pineapple and grapefruits are not known to cross react. However you may be at a higher risk of developing allergy to other citrus fruits from grapefruit allergy.

Avoidance: Currently the best treatment approach for food allergies (including pineapple) is to avoid ingesting it. In the future, there will likely be methods of oral desensitization, but these are not ready for "prime time.".

Your immune system: You have a tendency to develop allergies to foreign proteins in your diet. I am interested in your wine allergy. Reactions to wine are either pharmacologic - the alcohol & other ingredients care drugs that cause nasal congestion or the sulfiting agents in the wine trigger asthma. Wine is often clarified by dropping a raw egg through it. If you are very allergic to egg this could be a denominator.

Pineapple: This is not an allergy. Is it perhaps that the fruit is too acidic?

Unusual: A true allergy to pineapple is highly unusual however pineapple can cause sores in the mouth. You will need to be more specific about the allergies on your face.

Allergy: Avoid pineapple juice for now.

IBS, a functional: Disorder, not a disease, can occur in kids with chronic stress, especially from physical or psychological abuse, but essentially never in toddlers. Test for milk protein & other food allergies, celiac disease, lactose & fructose intolerance before restricting a toddler's diet. Excessive juice drinking can cause diarrhea in toddlers; they need none. Limit milk & milk products to 16-2- oz./day.

Identify, avoid, med: In order to reduce allergy symptoms, it is key to identify what the allergy is. See an allergist for testing. After identification, avoidance measures as possible followed by medications. If one is still suffering from allergies despite avoidance measures and medications, then allergy injections may be a very good option.

Nasal symptoms: Cedar pollen allergy causes runny nose, congestion, sneeze and itchy/watery eyes.

Depends: Upper airway: stuffy nose, itchy nose, sneezing, sniffing, itchy roof of mouth or throat, itchy, watery eyes. Lungs: coughing, wheezing, chest pain, shortness of breath skin: itchy rash. (itchy without rash, rash not itchy is not allergy) gi: nausea, vomiting, diarrhea after eating certain foods. Gi symptoms are not specific to allergy. History is very important.

Depends on to what.: Allergy symptoms vary based on route of exposure. Examples: runny nose, sneezing and itchy nose with breathing pollen or dog dander, etc. Abdominal pain, nausea, hives with a food allergen.

Various: A medication allergy may cause severe symptoms such as rash or hives, swelling of the tongue or throat, difficulty breathing, drop in blood pressure, loss of consciousness, or death.
