Your lips swell after eating apples due to Oral Allergy Syndrome (OAS), also called Pollen Food Allergy Syndrome, where your immune system mistakes apple proteins for birch pollen proteins (if you have pollen allergies), causing mild, localized reactions like itching and swelling of the mouth, lips, and throat. This is a common cross-reaction, but it's best to see a doctor for proper diagnosis and management, which may involve avoiding raw apples or cooking them.
LTP is an extremely stable protein that is resistant to food processing and to gastro-intestinal digestion. Most apple allergic patients notice itching of mouth and throat, and itching, redness and swelling of the lips, within the 5-15 minutes after eating the fruit, or even while chewing and swallowing it.
Oral Allergy Syndrome (OAS)
This reaction occurs because the proteins found in some fruits and vegetables are very similar to those found in pollen. These proteins can confuse the immune system and cause an allergic reaction or make existing symptoms worse, which is referred to as cross-reactivity.
Common symptoms of a food allergy include: feeling dizzy or lightheaded. itchy skin or a raised rash (hives) swelling of the lips, face and eyes (angioedema)
If a protein in a fruit or vegetable is similar to a pollen protein that you're allergic to, it will cause a reaction inside your mouth like the reaction the pollen would cause inside your nose. This is called cross-reactivity, or pollen-food allergy syndrome.
An allergy is a reaction that your body has to something it thinks is harmful. In oral allergy syndrome, your immune system makes your lips and mouth swell up because it mistakes certain foods (trigger foods) for something harmful in your body.
The most common cross-reactivities with apple include cherries, peaches, hazelnuts, peanuts, carrots, pears, raspberries, strawberries, and mulberries.
1. Lupus erythematosus: Chronic lip swelling.
Most of the food mentioned by the investigated subjects such as cheese, alcoholic beverages, fish, tomatoes, strawberries, pineapples, nuts, citrus fruits and kiwis contain or release histamine [22]. Therefore a histamine intolerance reaction is probably associated with the induction of angioedema.
As for temporary irritations, spicy foods might bother your lips or cause them to burn. Salty foods such as potato chips or popcorn might dry out your lips if you eat too much.
If you find you can no longer eat apples without experiencing symptoms like itching or swelling in your mouth, you may have developed Oral Allergy Syndrome (OAS). This occurs when your immune system mistakenly identifies apple proteins as similar to pollen allergens, causing an allergic reaction.
If you have oral allergy syndrome that reacts to pineapple, you should probably also avoid apples, peaches, apricots, cherries, plums pears, caraway, fennel, coriander, aniseed, carrot, celery, parsley, soybeans, peanuts, almonds, and hazelnuts.
You think it couldn't be a food allergy because you've eaten this same meal many times over the years and you're an adult with no history of food allergies. The truth is, while most food allergies do start in childhood, they can develop at any stage of life.
Skin Reactions: Hives, eczema, or contact dermatitis can develop upon direct skin exposure to apple allergens. Respiratory Symptoms: In rare cases, individuals with severe apple allergies may experience difficulty breathing, wheezing, or nasal congestion due to an allergic reaction.
Swelling of the tongue, lips and throat can come on after a few minutes and can be quite dramatic. This can have a rapid onset within minutes. The symptom of tongue and lip swelling can be very extensive and can last for a few hours or longer until it resolves.
Fresh Fruits and Vegetables: Opt for fresh fruits and vegetables that are not known triggers for angioedema. Examples include apples, pears, carrots, and cucumbers. Lean Proteins: Choose lean proteins like chicken, fish, and tofu as they are less likely to cause allergic reactions or trigger angioedema.
There are case studies that demonstrate an association between angioedema and low vitamin D levels. Resolution is reported in some patients once normal vitamin D levels are achieved. This may be more important when living at norther latitudes.
Medication is the main treatment for angioedema, although many cases get better after a few days without treatment. Allergic angioedema and idiopathic angioedema are usually treated in the same way, using a combination of antihistamines and corticosteroids to help relieve the swelling.
Angioedema is swelling in the tissue under your skin. It's most common in your lips, eyelids, tongue, genitals, hands and feet. Causes include allergies, medication side effects, vibrations, inherited gene changes and some health conditions.
Key Takeaways. People with lupus may experience chapped, dry, and peeling lips as part of their condition, which can be particularly bothersome during flares.
The most common causes of lip inflammation are vitamin B2 and iron deficiencies. You can find out whether this applies to you by having a blood count analysis done by your doctor.
Early lupus warning signs often mimic other illnesses, but key indicators include extreme fatigue, fever, joint pain/swelling, skin rashes (especially a butterfly-shaped rash on the face), hair loss, and sensitivity to sunlight, alongside potential issues like headaches, mouth sores, and fingers/toes turning white or blue in the cold (Raynaud's). These symptoms can appear suddenly or slowly and come and go in flares.
Taylor Swift has severe food allergies to peanuts, tree nuts, eggs, dairy, and peas, which significantly impacts her dining and event planning, requiring extreme caution with food preparation and cross-contamination, a reality friends like Lorde have compared to managing an autoimmune condition. She emphasizes awareness and has shared her need for vigilance, from ensuring restaurants use clean utensils to avoiding contaminated granola bars, to keep her safe from potentially life-threatening reactions.
A great variety of different fruits have been reported as causing allergic reactions, however, the most prevalent and best described are reactions to apple, peach and kiwi fruit.
The eight foods responsible for about 90% of food allergies are milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat. A ninth allergen, sesame, was recently added to this list in the U.S., making it the "Big 9" due to its prevalence and the severe reactions it causes.
