If you or your child has ever battled麻疹, you know they can be frustrating. Hives, also called urticaria, usually start with itching. It’s hard to resist scratching that itch, and when you do, your skin develops raised welts that look a lot like mosquito bites. If you have light skin, a red area will probably surround the welt. On darker skin, the welts might be slightly lighter or darker than your skin, or you might not notice a color change. The more you keep scratching, the more hives you develop.
威廉克拉弗, MD, an adult and pediatric allergist and immunologist at主頁(欢迎您)横幅健康Clinicin Loveland, CO, said, “Hives are relatively common. Up to 20 percent of people develop them at some point in their lives.”
很多人都会得到急性荨麻疹 - 这些可以持续几个小时或几天，尽管他们稍后会再次再次出现。有些人有慢性荨麻疹，每周开发两三次超过六个星期。
Most of the time, hives are only a problem that affects your skin. But rarely, they can cause sneezing, runny nose, watery eyes, wheezing, coughing, trouble breathing, gastrointestinal symptoms, low blood pressure and shock.
这是导致你的荨麻疹的原因
有很多不同的东西可能会引发荨麻疹的爆发。您可能会在几分钟，小时或几天内开发荨麻疹：
- 昆虫叮咬
- Antibiotics and some other medications
- Vitamin and mineral supplements
- Herbal remedies
- 接触with an animal
- Certain foods
- Infections includingcolds,咽喉炎和mononucleosis
- 暴露于冷或热量，如热淋浴
- 压力
“Hives are often called ‘allergic,’ but quite often,allergydoes not play a role,” Dr. Culver said.
But a lot of times, when you develop hives, you can’t pinpoint what caused them. And despite what you may have heard, it’s rare to develop hives from contact with detergent, lotion or fabric. This can happen occasionally, but it’s usually easy to identify since the hives disappear when you stop using the product. If you’re prone to hives, introduce new products slowly to watch for a reaction.
“尝试确定导致你的荨麻疹的内容是很重要的，但并不总是有可能的。不幸的是，当你不知道什么是触发你的荨麻疹时，这是令人沮丧的，“卡尔弗博士说。如果荨麻疹成为慢性，你没有发现触发器，那么你就不太可能弄清楚导致它们的东西，并控制它们是你最好的选择。
这是你如何对待你的艾滋病毒es
Antihistamines are the best choice for treating hives. Talk to your doctor about the correct dose of antihistamine to help get your hives under control. “Often, doses of antihistamines are too low,” Dr. Culver said. “Current guidelines suggest you might need up to four times the normal dose of antihistamines to control your symptoms.” If you don’t get relief with antihistamines, your doctor might prescribe a steroid. If antihistamines and steroids don’t get your hives under control, you can talk to your doctor about other treatment options.
When you know what causes your hives, you can try to avoid that trigger. If you can’t figure out what’s causing them, taking antihistamines regularly can prevent them or keep them from becoming so severe.
You can also take steps to minimize hives when outbreaks occur:
- Avoid scratching so you don’t make hives worse. Sometimes, when hives are flaring, just stroking the skin can cause them to erupt.
- Wear loose-fitting clothing since places where belts, straps or fabric touch the skin can be prone to hives during an outbreak.
- Avoid aspirin and non-steroidal anti-inflammatory drugs such as Advil and Motrin, which could make hives worse.
Here’s when you should see a health care provider for your hives
如果抗组胺药没有得到控制，如果荨麻疹正在重现或干扰你的生活方式，或者如果发生喘息，呼吸急促，胸闷或超越瘙痒的任何症状，你应该看到医疗提供者。
