What Causes Anaphylaxis?

Anaphylaxis is a potentially life-threatening allergic reaction that can affect people of any age. It occurs when the body's immune system overreacts to a foreign substance, such as a food allergen, medication, or insect venom. This can cause a wide range of symptoms, from mild hives, sneezing and itching to severe breathing problems and anaphylactic shock.

In this blog post, I will discuss what triggers anaphylaxis and the risk factors involved.

1. Medication

Medication is the leading cause of anaphylaxis in adults. Many medications, including antibiotics, painkillers, and antidepressants, can trigger an anaphylactic reaction. If you are taking any new medication, be sure to ask your doctor if it is safe for you to have an epinephrine auto-injector (such as EpiPen) on hand in case of an emergency. Also, be sure to read the labels of all over-the-counter medications and supplements to see if any of them contain allergens. For example, some people are allergic to sulfites, a common preservative found in many wines and dried fruits.

2. Food Allergens

Food allergies are the leading cause of anaphylaxis in children. The most common food allergens include peanuts, milk, eggs, and shellfish. If your child has a food allergy, be sure to read food labels carefully and avoid any foods that may contain the allergen. Also, make sure your child always carries an epinephrine auto-injector in case of an emergency.

Food properties that can cause anaphylaxis:

-Food colourings. These are found in various foods, including candy, soft drinks, and ice cream.

-Food additives, such as sulfites, monosodium glutamate (MSG), and nitrates. Sulfites are common food additives used to preserve foods like dried fruit, wine, and pickles. MSG is a flavour enhancer found in many Chinese foods and fast-food restaurants. Nitrates are preservatives used in cured meats, such as ham and bacon.

-Foods that contain proteins from eggs, milk, peanuts, tree nuts, soy, wheat, fish, and shellfish. These foods include cookies, cakes, salad dressings, loaves of bread, and pasta.

-Food preservatives like benzoates, sulfites, and nitrates. These are used in various foods, including soft drinks, juices, and pickles.

3. Insect Bites and Stings

Insect bites and stings are a common cause of anaphylaxis in adults and children. The most common insects that can cause a reaction are wasps, bees, hornets, yellow jackets, and fire ants. If you are stung by an insect, be sure to remove the sting carefully and seek medical help if you develop any symptoms of anaphylaxis.

In addition, if you are travelling to a foreign country, be sure to take precautions against insect bites and stings. Wear long pants and sleeves, use insect repellent, and avoid areas where insects are known to congregate.

4. Sudden Physical Activity

Sudden physical activity causes anaphylaxis in people who are susceptible to it.  It is extremely rare. This includes activities like running, jumping, or dancing. If you are prone to anaphylaxis, be sure to avoid any strenuous physical activity before eating or drinking.

Also, be sure to drink plenty of fluids before and during physical activity, especially in hot weather. This will help prevent dehydration, which can also trigger anaphylaxis.

5. Alcohol


Although alcohol allergies are rare, alcohol can also trigger anaphylaxis in some people. If you are prone to reactions, avoid drinking alcohol altogether. Also, be sure to eat a substantial meal before drinking alcohol. This will help reduce the risk of a reaction. Also, be sure to drink in moderation, as excessive alcohol consumption can also trigger anaphylaxis.

6. Latex


Latex is a common allergen that can cause anaphylaxis in some people. If you are allergic to latex, avoid any products that contain latex, including condoms, gloves, and balloons. In short, latex is a common allergen that can cause anaphylaxis in some people. If you are allergic to latex, be sure to avoid any products that contain latex. Also, tell your doctor if you are allergic to latex, as they may need to prescribe a different type of medication for you.

7. General Anaesthetic 

General anaesthetic can also cause anaphylaxis in some people. If you are scheduled for surgery, be sure to let your doctor know if you have a history of allergic reactions. Surgical procedures can also cause anaphylaxis in some people. He or she may need to take special precautions to prevent a reaction.

8. Outdoor Allergens


Outdoor allergens, such as pollen and mould can also trigger anaphylaxis in some people. If you are allergic to these allergens, be sure to stay inside as much as possible during periods of high exposure. Also, take a daily antihistamine to help control your symptoms. In addition, keep your windows and doors closed to prevent any allergens from entering your home.

Overall, anaphylaxis is a potentially life-threatening condition that can cause various symptoms. If you are experiencing any of these symptoms, seek medical help immediately. Anaphylaxis can be treated with epinephrine, so it is important to get medical help as soon as possible. In addition, if you are prone to anaphylaxis, be sure to carry an EpiPen with you at all times. This will allow you to inject yourself with epinephrine in the event of a reaction. Be sure to follow all of the precautions listed above to reduce your risk of anaphylaxis. These precautions include avoiding potential triggers, carrying an EpiPen, and staying inside during periods of high exposure. By following these precautions, you can help prevent anaphylaxis from occurring.
