“I am so allergic to them!” We often use this phrase when talking about people we just don't click with, don't we? But have you ever wondered why we develop actual physical allergies? Just like some people simply don't fit into your life, your immune system can sometimes perceive harmless things as dangerous invaders. Imagine having to share a room with someone you can't stand—that is essentially what an allergy is like for your body.
Today, let's talk about the allergies we face in our daily lives. This topic reminds me of an incident during my time as a medical student. My friends and I had just finished a stressful assignment and decided to head to a restaurant near campus to celebrate. We had a habit of de-stressing by indulging in a hearty meal. We ordered the restaurant's signature rice dish, which was filled with chicken, carrots, leeks, green peas, and chunks of pineapple. We were chatting away, completely unaware that our meal was about to take a turn for the worse. Suddenly, my friend Rumeshi said, “Hey, my mouth feels a bit strange.” We all looked at her. Her lips were swelling, and she was breaking out in hives. “I feel like I can't breathe,” she gasped. Realizing this was an emergency, we rushed her to the hospital immediately. After being treated for anaphylaxis, she finally recovered. It was a scary lesson for all of us.
Now, let's look at what happened to Rumeshi and dive deeper into the science of allergies.
What are allergies?
An allergy is essentially a misunderstanding within your immune system. It can be life-threatening. It occurs when your body incorrectly identifies a harmless substance as a threat and launches an attack against it. This can be triggered by food (like the pineapple for Rumeshi), pet dander, pollen, dust mites, medication, or latex. When exposed to these triggers, your body produces antibodies called IgE, which set off an allergic reaction.
Types of Allergies
Food
Common food allergies include nuts, shellfish, dairy, certain fruits, seafood, and red meat.
Hay Fever
This happens when you inhale allergens like dust or pollen, leading to sneezing, runny nose, and itchy eyes.
Asthma
People with asthma may find their symptoms worsened by dust or pet dander. When allergy and asthma coexist, it is referred to as allergic asthma.
Atopic Dermatitis (Eczema)
This involves skin irritation, itching, and rashes caused by contact with an allergen.
Drug Allergies
Sometimes, the medications meant to help us can cause unexpected reactions. Certain individuals may be allergic to specific antibiotics or pain relievers.
Insect Stings
For some, the venom from a bee, wasp, or ant sting can trigger a severe, life-threatening allergic reaction.
Symptoms of Allergies
Symptoms vary from person to person. In Rumeshi's case, it progressed to a life-threatening level, but not everyone experiences such severe reactions.
Mild Symptoms
Sneezing, runny nose, coughing, and mild skin itching.
Moderate Symptoms
Vomiting, localized swelling, and difficulty breathing.
Severe Symptoms
Swelling of the face and throat, shortness of breath, dizziness, and fainting.
This is a medical emergency known as anaphylaxis. If this occurs, you must seek immediate medical attention at the nearest emergency department.
Why do allergies happen?
While the exact cause is sometimes unclear, it is believed to be a combination of genetic factors, family history, age, hormonal changes, and the composition of your gut microbiome.
How are allergies diagnosed?
If you suspect you have an allergy, consult your doctor. Rumeshi was able to manage her condition through medical diagnosis. Common tests include:
1. Blood Test
This measures the amount of IgE antibodies in your blood to identify specific allergens.
2. Skin Prick Test
A small amount of a suspected allergen is placed on the skin, and the area is pricked. If a red bump appears, it indicates an allergy.
Treatments
The best treatment is avoidance. Rumeshi now strictly avoids pineapple. However, if exposure occurs, the following treatments can help:
1. Medications
Antihistamines (like Claritin or Zyrtec), corticosteroids, and decongestants can help manage symptoms.
2. Immunotherapy
This involves gradually introducing small amounts of the allergen to your system to help your body build tolerance over time, under strict medical supervision.
3. Emergency Epinephrine
For severe, life-threatening reactions, epinephrine is essential. People with known severe allergies should carry an autoinjector (EpiPen). We used one for Rumeshi before rushing her to the hospital, which helped stabilize her condition.
Simple Remedies
While not substitutes for medical treatment, some find relief through:
1. Saline nasal irrigation
Helps clean the nasal passages.
2. Humidifiers
Adding moisture to the air can ease breathing.
3. Essential oils
Some people find relief with oils like eucalyptus, though caution is advised as they can sometimes trigger further reactions.
Prevention is Key
Avoiding known allergens is your best defense. If you have severe allergies, keep your EpiPen with you and keep your living environment clean to reduce exposure to dust and other irritants.
Complications
As seen with Rumeshi, allergies can lead to serious consequences. Anaphylaxis can be fatal within minutes if not treated immediately.
Allergies in Children
Allergies are common in children. Studies show a significant number of children suffer from at least one form of allergy, making early detection and preparedness vital.
Frequently Asked Questions
What are the most common food allergens?
Milk, sesame, eggs, fish, wheat, shellfish, soy, peanuts, and tree nuts.
What should I do in an emergency?
For mild symptoms, antihistamines may suffice. For signs of anaphylaxis, use an epinephrine injector immediately and head to the nearest emergency room.
Final Word
Allergies are serious but manageable with the right medication and lifestyle adjustments. If you suspect an allergy, seek professional advice, and if you are at risk of severe reactions, always carry an emergency injector.
Rumeshi's experience was a valuable lesson in our medical careers and our daily lives. Identifying allergies early can save lives.
