Hives and angioedema can present at the same time, angioedema is a type of swelling that can block the airways, preventing a person from breathing. Angioedema is a symptom of anaphylaxis, which is a medical emergency.

• Widespread skin reactions, including hives and itching and flushed or pale skin
• Low blood pressure (hypotension)
• Constriction of your airways and a swollen tongue or throat, which may cause wheezing and trouble breathing
• A weak and rapid pulse
• Nausea, vomiting or diarrhea
• Dizziness or fainting

People at risk of anaphylaxis are usually prescribed epinephrine. This emergency medication comes in the form of an auto-injector and you’ll receive training on how to use the device from your healthcare provider.

Keep two auto-injectors with you at all times. Use one immediately when you experience symptoms of anaphylaxis and seek immediate medical attention or go to the emergency room. You may feel better after the first dose of epinephrine but there’s a risk of developing a second delayed reaction.

Allergens that can cause contact urticaria include, but are not limited to: foods, such as nuts, seafood, wheat, milk, eggs and medications, such as penicillin or anti-inflammatory drugs

More often though, people tend to experience contact urticaria through irritants rather than allergens. Symptoms of contact urticaria caused by irritants are typically less severe than those caused by allergens.

Confusingly, there is a lot of overlap between irritants and allergens that can cause contact urticaria. For example, some animal products, foods, medications and plants can all be irritants as well as allergens. So, for this reason if you do experience contact urticaria, you should always speak with your healthcare provider who can check if you have an allergy or not.

Solar urticaria is a rare allergic reaction to sunlight where hives can develop within minutes of sun exposure. Other allergy symptoms such as nausea and shortness of breath can happen if you’ve been in the sun for a long time or had a large area of skin exposed.

Wearing thin or white clothing sometimes isn’t enough to prevent sun exposure; you should aim to wear darker clothing. And apply a broad-spectrum sunscreen to block both UVA and UVB rays.

Cholinergic urticaria is a type of hives that develops when your body temperature is high enough for you to sweat. Researchers don’t fully understand why cholinergic urticaria happens but think that it involves the release of histamine.

Cholinergic urticaria can sometimes be confused with heat urticaria. Heat urticaria is a very rare type of physical urticaria where exposure to medium heat causes hives. For example, if you submerge your hand in warm water, hives may develop on your hand. With cholinergic urticaria, you must begin to sweat or the sweating reflex needs to be activated for you to develop hives.

Diagnosing hives, or more accurately allergic reaction hives, may require several tests. These could include blood tests to rule out infection or other skin rashes caused by the immune system. Your healthcare provider may also ask questions about what you were doing before the hives appeared. This helps them determine if your hives were a symptom of an allergic reaction.

When treating allergic reaction hives, the aim is to control symptoms and avoid future episodes of hives. So, once a healthcare provider diagnoses the cause of allergic reaction hives, they’ll create a treatment plan to suit your needs. For instance, they’re likely to suggest avoidance strategies to help reduce your exposure to the allergen, and taking antihistamines when this isn’t possible.

Treatment for more severe allergic reaction hives may include corticosteroids. Like antihistamines these aim to reduce inflammation and itching.

Allergic reaction hives can affect small or large areas of skin anywhere on your body. They also tend to develop first where you’ve encountered the allergen. Hives, like other allergy symptoms, may get worse if you’re repeatedly in contact with your allergen.

Yes, you could develop hives from infection. When this happens you usually have chronic hives – hives that last for 6 weeks or more. Bacterial infections that have been linked to hives include Helicobacter pylori, which commonly causes stomach ulcers. Viral infections can also cause hives, such as hepatitis and norovirus. Researchers are still understanding why some bacteria and viruses cause hives but think it could be due to how a person’s immune system responds to the infection.

Chronic hives last for 6 weeks or more and are usually linked with infection and autoimmune conditions, for example thyroid disease. Hives caused by allergies are usually acute hives and tend to go away within 24 hours – providing the person is no longer in contact with the allergen. Or has received treatment for their allergic response.

2. Vermeide die Verbreitung allergener Erdnussproteine

• Mache es dir zur Gewohnheit, am Tisch zu essen und einen Teller zu verwenden.
• Reinige Küchenoberflächen, an denen Erdnussrückstände vorhanden sein könnten, mit einem Einwegtuch.
• Dasselbe gilt für Pfannen und Utensilien, wenn du mit Erdnüssen kochst.

3. Und achte darauf, sie nicht versehentlich zu essen

• Teile weder Tassen noch Besteck, da Erdnussproteine im Speichel zurückbleiben können.
• Warne auch dein Date, dass du niemanden küssen kannst, nachdem er oder sie Erdnüsse gegessen hat.
• Lasse dich von den Hunden anderer Menschen nicht ablecken, es sei denn, du weißt sicher, dass ihre Besitzerin oder ihr Besitzer erdnussfreies Haustierfutter und Leckerlis kauft.

Allergic reaction hives look like reddish pink bumps on pale skin. They may be more difficult to spot on darker skin as the bumps tend to be a similar color. In both skin types, hives appear in raised batches.

Doctors tend to treat allergic reaction hives with antihistamines but there are other medications for more severe cases. Anaphylaxis is a life-threatening systemic allergic reaction that requires urgent medical treatment, usually with epinephrine.

Allergic reaction hives are a type of acute urticaria. The bumps tend only to last for 24 hours, providing a person has received treatment or is no longer in contact with their allergen. Chronic hives last longer than 6 weeks and are typically a symptom of an infection or an autoimmune condition.
