What is Anaphylaxis?

Anaphylaxis is a serious and potentially life-threatening allergic reaction that can happen swiftly after exposure to an allergen. The reaction can occur within seconds or minutes and can affect the whole body. It is considered a medical emergency, requiring immediate treatment to prevent the situation from worsening.

Causes of Anaphylaxis

Anaphylaxis is commonly triggered by certain foods, medications, insect stings, or latex. In the UK, nuts, shellfish, eggs, and dairy products are frequent food culprits. Medications such as penicillin and aspirin, as well as bee or wasp stings, are also common causes. Less common triggers include physical exercise and exposure to cold temperatures, especially when preceded by the consumption of specific foods or medications.

Symptoms of Anaphylaxis

The symptoms of anaphylaxis can vary, but they typically develop quickly. Common signs include hives, swelling of the face, lips, or throat, and difficulty breathing. Other symptoms may be a rapid heartbeat, a sudden drop in blood pressure, dizziness, confusion, or loss of consciousness. Gastrointestinal symptoms such as vomiting, diarrhoea, or abdominal cramps may also occur.

Diagnosis and Treatment

Diagnosing anaphylaxis is primarily based on the identification of symptoms following exposure to a known allergen. Medical professionals may use blood tests or skin tests after the acute phase to determine the specific allergens involved. Once diagnosed, the primary treatment for anaphylaxis is an injection of adrenaline, also known as epinephrine. This is commonly administered via an auto-injector, such as an EpiPen, which individuals prone to severe allergies should carry at all times.

Prevention and Management

Preventing anaphylaxis involves avoiding known allergens and being prepared to treat accidental exposure. It is crucial for individuals at risk of anaphylaxis, and their families and carers, to recognize the signs of an allergic reaction and know how to use an adrenaline auto-injector. Wearing a medical alert bracelet and having an action plan can significantly aid in managing the condition. Regular consultation with an allergist can help refine avoidance strategies and prevent future episodes.

Living with Anaphylaxis

Living with the risk of anaphylaxis can be challenging, but with the right precautions, people can lead normal and active lives. Education on anaphylaxis management should extend to schools and workplaces to ensure a safe environment. Public awareness campaigns in the UK aim to improve understanding and reduce the stigma associated with severe allergies. Support groups and online resources can provide guidance and connect individuals facing similar challenges.

What is Anaphylaxis?

Anaphylaxis is a very serious allergic reaction. It can happen fast after you touch something you are allergic to, called an allergen. This can happen in just a few seconds or minutes. Anaphylaxis can make you very sick, so you need a doctor’s help right away.

Causes of Anaphylaxis

Things like certain foods, medicines, insect stings, or latex can cause anaphylaxis. In the UK, foods such as nuts, shellfish, eggs, and dairy are common triggers. Some medicines like penicillin and aspirin, and bee or wasp stings, can also cause anaphylaxis. Sometimes, exercise or being cold, especially after eating certain foods or taking certain medicines, can lead to anaphylaxis.

Symptoms of Anaphylaxis

Anaphylaxis symptoms usually happen quickly. You might get itchy red spots called hives, or your face, lips, or throat might swell up, making it hard to breathe. Other signs include a fast heartbeat, feeling dizzy or confused, and even fainting. You might also feel sick, have a tummy ache, or get diarrhoea.

Diagnosis and Treatment

Doctors look for signs of anaphylaxis after you’ve been near something that causes your allergies. They might do blood or skin tests later to find out exactly what you are allergic to. To treat anaphylaxis, you need an injection of a medicine called adrenaline. This is usually done using a special pen, like an EpiPen, which people with severe allergies should always have with them.

Prevention and Management

To stop anaphylaxis, try to avoid the things you're allergic to. Be ready in case you accidentally come into contact with them. It's important for you, your family, and caregivers to know the signs of an allergic reaction and how to use the adrenaline pen. Wearing a medical bracelet can help. Having a plan helps you stay safe, and seeing an allergy doctor can help you avoid future problems.

Living with Anaphylaxis

Having anaphylaxis can be tough, but you can still live a normal life with the right precautions. It’s important for schools and workplaces to know what to do if someone has an allergic reaction. In the UK, there are campaigns to help people understand severe allergies better. Support groups and online help can connect you with others and offer support.
