A person’s allergy symptoms can be light or extreme. An allergic reaction that can be extremely serious and even dangerous is called anaphylaxis. The most common anaphylactic reactions are to foods, medicines, latex, insect stings, and foods.

Your immune system overreacts to an allergen when you have an allergy, releasing chemicals that lead to allergy symptoms. These unwanted symptoms typically affect just one part of the body. However, some people can experience an anaphylactic reaction, which is far more serious. Usually, more than one area of the body is affected together by this reaction.

Anaphylaxis requires quick medical attention, which includes a trip to the emergency room at a hospital. It can happen within seconds or minutes of exposure to specific allergens. If not treated immediately, it may cause deadly conditions like shock and other major consequences affecting different body systems.

Today, we’re taking a look to find out what is anaphylaxis and its remedy.

Symptoms of Anaphylaxis

Most people are confused about what is anaphylaxis. Moreover, there are also confutations regarding the term anaphylaxis. We can define anaphylaxis as a severe allergic reaction that can be dangerous. Being exposed to an allergen, like peanuts or bee stings, can happen seconds or minutes later.
The anaphylaxis signs and symptoms include:

  • feeling faint
  • breathing problems, such as fast or weak breathing
  • wheezing
  • a fast heartbeat
  • rough skin
  • fear and worry
  • becoming unconscious

What to Do If Someone Has Anaphylaxis?

If someone has anaphylaxis, the following actions can be taken:

  1. If the person has an adrenaline auto-injector, use it, but first, ensure you know how to use it.
  2. Even if they start to feel better, call 999 for an ambulance right away and let them know you think they are having anaphylaxis.
  3. If possible, remove any triggers; for example, carefully remove any stingers that may be stuck in the skin.
  4. If the person has breathing problems and needs to sit up to help them, lay the person down and up their legs. If they are pregnant, place them on their left side.
  5. Give another injection after 5 minutes if there is no improvement and a second auto-injector is available.

If you feel confident, you can perform these actions on your own if you have an anaphylactic reaction.

Causes of Anaphylaxis

The body’s natural defence system, the immune system, reacts badly to a trigger, resulting in anaphylaxis.

This is often something you’re allergic to, but not always.
Common triggers for anaphylaxis include the following:

  • Foods include nuts, milk, seafood, shellfish, eggs, some fruits, and dairy products.
  • Medicines, including some antibiotics and NSAIDs (non-steroidal anti-inflammatory drugs), like aspirin.
  • Stings from insects, especially spider and bee stings.
  • Contrast agents are colours that are used in some medical exams to make particular body parts stand out more on scanners.

Some condoms and rubber gloves include a type of rubber called latex.

Sometimes there is no obvious trigger. This is known as idiopathic anaphylaxis. Usually, anaphylaxis starts suddenly and soon gets worse. Anaphylactic shock can result from an anaphylactic allergic reaction. When your body gets an anaphylactic shock, your blood pressure suddenly drops and your lungs collapse, effectively stopping regular breathing.

Preventing Anaphylaxis

Take steps to avoid similar incidents if you have a serious allergy or have already experienced anaphylaxis.

You can reduce your risk by doing the following:

Identify triggers

You should contact an allergy clinic for tests to find any triggers if you have experienced anaphylaxis but have not yet been given an allergy diagnosis.

Take steps to avoid similar incidents

The most common tests are:

  • A skin prick test
    A limited amount of a suspected allergen is prickled onto your skin to check if it reacts.
  • A blood test
    Your blood is taken to test how it responds to a possible allergy.

Avoid triggers

If a trigger has been found, you must take steps to avoid using it whenever possible. Here are some ideas we have for keeping away from particular triggers.

Food

The risk of coming into contact with a food allergy can be reduced by:

  • Checking the ingredients and labels on food.
  • Letting a restaurant’s workers know what you’re allergic to so it won’t be present in your meal.
  • Keeping in mind that some foods may contain a small number of allergens.

Insect stings

By taking simple safety measures, such as the following, you can lower your risk of being stung by an insect:

  • Moving slowly and quietly away from hornets or bees.
  • If you spend time outside, especially in the summer, using bug sprays.

Medicines

There are usually safer options if you have an allergy to a particular class of medicine.

For example, if you have an allergy to:

  • Penicillin
    Usually, taking a different class of antibiotics known as macrolides is safe.

  • Non-Steroidal Anti-Inflammatory Medications (NSAID)
    Paracetamol is often safe to take. However, you should carefully review products’ ingredients like cold medicines to ensure they do not contain NSAIDs.

Always let a health professional know if you have any medicine allergies because they might not be aware of them.
