多于50 million Americanshave an allergy of some kind. Food Allergy Research and Education (FARE) estimates up to15 million peoplein the United States have a food allergy.
皮疹是如果您对食物有过敏反应，可能会出现几种常见症状之一。继续阅读以了解更多有关食物皮疹的外观以及您可以对它们做什么的信息。
Food allergy reactions don’t always include rashes. However, rashes associated with food allergies have symptoms such as:
与食物接触后不久就会出现皮疹。有了食物敏感性，它可能会出现在您的嘴巴，脖子或脸上 - 基本上，食物与您的皮肤接触。
It’s also possible to have a rash on other parts of your body. This is more common with a food allergy. Overall, the symptoms of a food allergy rash are the same among children and adults.
如果您还有其他食物过敏的症状，例如：
- abdominal cramps
- diarrhea
- 痒或水眼
- itchy, stuffy nose
- 打喷嚏
- 呕吐
Food allergy rashes are caused by ingesting foods you’re allergic to. Your immune system treats the proteins in the food as harmful substances and tries to fight them. Even trace amounts can lead to an allergic reaction.
According to the美国过敏，哮喘和免疫学学院（AAAAI）, the most common food allergens include:
- cow’s milk
- 蛋
- fish
- nuts
- 花生
- shellfish
- 大豆
- wheat
While these are the most common, it’s possible to be allergic to any food. In fact, FARE estimates thatat least 170 foodscan cause allergies.
There’s also the possibility of cross-reactivity. For example, if you’re allergic to ragweed, you could also be allergic to foods in the same family, such as melons. A common cross-reactive allergy is latex and foods. People with latex allergies may also be allergic to fruits including bananas, kiwi, and avocado.
Food allergies are often detected during early childhood as a result of an adverse reaction to a particular food. Blood or skin tests can also help diagnose food allergies. Many孩子们outgrow food allergies, but it’s possible to have lifelong allergies. Adults can also develop new food allergies, though this is less common.
The only way to avoid an allergic reaction is to avoid a food allergen entirely. While food labels are very important, it’s also important for you to be prepared in case of a reaction.
一旦潜在的反应停止，食物过敏皮疹最终消退。帮助的最佳方法之一是停止暴露于过敏原。
Wash up
Wash your hands and face, if needed, as well as any surfaces that may have come in contact with the suspected food. This can help prevent more rashes. Some people rinse off with a quick shower.
Apply a soothing cream or gel
If the rash is bothersome, you can apply over-the-counter (OTC) creams, such as hydrocortisone.
服用抗组胺药
Anoral antihistaminecan also help. These will help alleviate the itchiness, inflammation, and overall discomfort.
有不同的OTC抗组胺药，每个抗组胺药都有不同的活性成分。有些人可能比其他人和您的症状更好。抗组胺药在您的系统中积聚需要时间。您不应该混合抗组胺药。在出现皮疹时，采取一种类型的抗组胺药。

与医生说话
For your long-term health and comfort, it can be helpful to consult an allergist or even a nutritionist or dietitian. An allergist can help you to identify your allergens and determine what OTC antihistamine is appropriate for you.
In addition, a nutritionist or dietitian can provide you with useful tips and suggestions for foods so you avoid your allergy trigger while still getting the right nutrition.
在您的免疫系统对食物反应后，食物过敏皮疹可能不会出现。根据食物和您的摄入量，这可能需要几个小时。其他情况可以在几分钟之内发展。
Scratching at it can make it last longer. This can also increase your risk for skin infection.
Once your immune system calms down, your symptoms will subside. Antihistamines and topical creams can help alleviate minor symptoms. Overall, the rash should subside within a day or two.
According toFARE，可能有第二波食物过敏症状，这可能在初次反应后长达四个小时发生，尽管这很少见。
Call your doctor if you think your initial food allergy rash has become infected. Signs may include inflammation, pain, and discharge. The size of the rash can also increase if it’s infected.
The most severe type of allergic reaction isanaphylaxis, which is a life-threatening condition. This is not a complication of a food rash itself, but rather a complication of the overall allergic reaction. Hives and anaphylactic reactions often occur together, but you can have hives without having anaphylaxis.
On top of the food allergy symptoms listed above, anaphylaxis may cause:
- 呼吸困难
- chest pain
- 头晕
- fainting
- low blood pressure
- 嘴，脸，颈部和喉咙中严重肿胀
- tightness in the throat
- tingling lips, hands, and feet
- wheezing
If your doctor recommends肾上腺素射击for severe food allergies, it’s important to keep them on hand at all times. Even breathing in a food allergen can cause severe issues. Also, the severity of a reaction may vary — just because one reaction was mild, doesn’t mean the next will also be mild.
过敏反应is a medical emergency. Call 911 or your local emergency services and take your epinephrine shot as soon as you experience symptoms. Antihistamines can’t treat anaphylaxis because the symptoms are too severe at this stage.
当您的免疫系统对您过敏的某种食物中的蛋白质不利反应时，就会发生食物过敏。这与食物不耐受不是一样。
Food intoleranceis primarily a digestive issue that can cause symptoms similar to food allergies, except that it’s not life-threatening.
Non-itchy rashes from a food intolerance can also develop over time, such as “chicken skin” on arms. This is unlike a food allergy rash, which tends to occur within minutes or hours of eating the suspected food. Food intolerance can also cause bloating, stomach pain, and mild digestive upset.
另一个关键的区别是,你可以有时have small amounts of a food without a problem if you have an intolerance. With an allergy, even a small amount of the food can cause issues.
According to theAAAAI，大多数可疑的食物过敏病例实际上是不宽容的。raybet雷竞技下载但是，您不想有机会进行自我诊断。过敏症患者可以帮助您确定差异。
If you suspect moderate to severe food allergies, make an appointment with an allergist. This type of specialist can准确诊断食物过敏raybet雷竞技下载and rule out any possible food sensitivities.
Since there’s no cure for food allergies, the best way to prevent them — and subsequent symptoms like rashes — is to avoid the culprit completely.
