With pollen, pet dander, dust, and food intolerances afflicting people—it’s no wonder that many of us are perplexed and overwhelmed by the myriad of allergies out there. But never fear! We’re here to help demystify this medical mystery and break down some of the most common and lesser-known types of allergies. From seasonal irritants to food sensitivities, let’s dive into the wild world of allergies!
1. Understanding Allergies: What Are They and What Causes Them?
Allergies are a subject of persistent misperception, oftentimes characterized by a confounding muddle of symptoms associated with its many varieties. The truth is that allergies are caused by an overly sensitive immune system that identifies normally harmless substances as a potential threat to the human body. Below, we’ll break down the common types of allergies and what causes them.
- Food Allergies – Food allergies occur when, upon consuming a particular food, the body detects a foreign antigen that it perceives as a threat. In response, it releases histamine into the bloodstream, which can cause symptoms such as hives, vomiting, and abdominal pain.
- Drug Allergies – Drug allergies can be identified when, upon taking a certain medication, the body releases histamine into the bloodstream, resulting in rashes, asthma, anaphylaxis, and other uncomfortable reactions.
- Insect Allergies – Insect allergies occur when a person’s skin comes into contact with certain insects, usually those belonging to the Lepidoptera family (butterflies, moths, etc.). People with insect allergies often experience itchy and inflamed skin.
- Pollen Allergies – Pollen, a substance released by flowers and trees, is usually harmless, but for some, contact with the allergen triggers an inflammatory response, resulting in breathing difficulties, sneezing, and facial congestion.
- Animal Allergies – Animal allergies occur when a person comes into contact with scales, fur, or proteins found in the saliva of animals. The body perceives these as intruders, resulting in discomfort such as hives, asthma, and even anaphylaxis.
- Dust Allergies – Dust allergies occur when a person’s immune system reacts to dust particles in the air. Common reactions include sneezing, itchy eyes, wheezing, and coughing.
- Mold Allergies – Mold allergies can be difficult to distinguish from dust allergies, as both involve inflammatory reactions to airborne particles. However, mold allergies generally cause more severe reactions, such as difficulty breathing and asthma.
By recognizing which type of allergy you suffer from, you can take the necessary steps to reduce your exposure to the allergen and avoid its accompanying symptoms, allowing you to enjoy life to the fullest.
2. The Different Types of Allergies
From seasonal allergies to food allergies, allergens can be found everywhere. With the variety of allergic reactions people may experience, it can be hard to differentiate between the various types. To help clear up the confusion, here’s a breakdown of and their symptoms.
Seasonal/Environmental Allergies
Pollen and fresh-cut grass are two of the most common triggers of seasonal environmental allergies. People can also be allergic to other substances from animals, like pet dander, urine, and saliva, as well as mold, dust mites, and cigarette smoke. These allergies may cause:
- Runny nose
- Sneezing
- Itchy and watery eyes
- Coughing
These allergies tend to be more common in the fall and spring, and can worsen during certain pollination periods. Avoiding these allergens can reduce any symptoms.
Food Allergies
Unlike seasonal allergies, food allergies have the potential to produce life-threatening reactions. Common food allergens are peanuts, tree nuts, eggs, dairy, soy, wheat, shellfish, and fish. If exposed to any of these, a person may experience:
- Hives
- Itching of the mouth
- Swelling of the face, lips, and tongue
- Wheezing
It’s important to read product labels carefully when shopping, as some food allergens aren’t visible or decipherable. Managing food allergies by avoiding or substituting the allergen is critical. It’s also beneficial to carry an EpiPen just in case.
Drug/Medication Allergies
Drug allergies are often caused by penicillin, other antibiotics, NSAIDs, nonsteroidal anti-inflammatory drugs, and chemo drugs. Though the symptoms vary, people may experience:
- Skin reactions such as hives or contact dermatitis
- Itching, swelling, or nasal discharge
- Shortness of breath or wheezing
- Abdominal pain, diarrhea, or nausea
Monitoring the body for any symptoms or reactions, while on the medication, is critical in order to manage any drug allergies.
Insect Sting Allergies
Bee, hornet, wasp, yellow jacket, and fire ant stings can cause a range of reactions from mild to life-threatening. People can experience:
- Redness and itchy raised bumps
- Hives
- Fainting, dizziness, or swelling of the tongue of face
- Shortness of breath
If an individual has an allergic reaction to an insect sting, seek medical attention immediately. If the doctor determines they’re at risk of a severe reaction, the individual may be prescribed an EpiPen to carry.
Though some allergies may appear harmless, they all have the potential to affect an individual’s health. By being aware of their own allergies as well as the symptoms associated with each type, they can take the necessary precautions to keep themselves safe and healthy.
3. Recognizing the Signs and Symptoms of Allergies
Allergies can affect people in different ways, so it is important to recognize the signs and symptoms and fluctuations in severity. Although seasonal allergies are common, there are also less obvious allergies that can have equally uncomfortable effects.
Dust Allergies
Dust allergies are very common, particularly in the home or office environment. Typical symptoms are sneezing, watery eyes, and a runny nose. They can also lead to sleep deprivation and a feeling of fatigue. Dust allergies can also cause a dry or hacking cough due to a reaction within the throat and bronchial tubes.
Animal Allergies
Dander is the cause of animal allergies, which can sometimes signal wheezing and difficulty breathing. These can often be characterised by sneezing, a runny nose, and watery eyes. It is also important to recognise the presence of eczema in regards to animal allergies.
Food Allergies
Food allergies can range in severity from skin rashes, to hives, to more serious reactions within the gastrointestinal system. Initially, food allergies can manifest with tingling around the mouth, vomiting, and a feeling of dizziness. Asthma is also a common symptom – this is caused by a reaction within the lungs, and can be indicated by wheezing and difficulty breathing.
Airbourne Allergies
Airbourne allergies occur in response to a particular inhalant that an immune system recognises as an irritant. Symptoms are similar to a hay fever response and can include itchy and watery eyes, as well as a sore throat, runny nose and sneezing.
4. Treatment Options for Common Allergy Types
Allergy sufferers often have a difficult time dealing with their condition, particularly when it comes to figuring out the most effective treatments. Fortunately, knowledge of the underlying causes of particular types of allergies can help to make choosing an appropriate treatment much easier.
1. Pollen Allergy (Hay Fever): Pollen allergies, also known as hay fever, are the result of airborne allergens such as grass and tree pollen. To reduce symptoms, the best treatment option is to stay indoors and limit exposure as much as possible. Additionally, using an air purifier can help to reduce the amount of airborne allergens.
2. Pet Allergy: Pet allergies are caused by dander from animals such as rabbits and cats. To reduce symptoms, the best treatment option is to keep the pet out of the home or to keep them off the furniture and carpets. Vacuuming regularly can also help to reduce the amount of dander in the household.
3. Dust Allergy: Dust allergies are caused by house dust mites that live in carpet, bedding, mattresses, and upholstered furniture. To reduce symptoms, the best treatment option is to wash bedding regularly and keep mattresses covered in a protective barrier, as well as vacuuming and dusting frequently.
4. Food Allergy: Food allergies are caused by reactions to certain proteins found in different foods. To reduce symptoms, the best treatment option is to avoid the foods that cause the reaction. It is important to note that food allergies can be very serious and, in some cases, life-threatening, and should only be treated under the supervision of a medical professional.
By understanding the causes of common allergy types, it is possible to select the most effective treatments for each type. Although allergies can create a variety of challenges, the right treatment options can help to greatly reduce the severity of symptoms.
5. How to Prevent Allergy Symptoms
1. Avoid Common Allergens
The best way to prevent allergy symptoms from happening in the first place is to avoid the allergens that trigger them. This can be difficult, since allergens are often found in the air or in food. Allergic asthma can be caused by triggers such as pet dander, dust mites, cockroaches, and mold. Allergic rhinitis may be triggered by pollen, mold, and pet dander. To reduce your exposure to allergens:
- Vacuum, mop, and dust your home often.
- Clean kitchen and bathroom walls, floors, and surfaces regularly to remove mold sources.
- Fix water leaks in your home right away to prevent mold and cockroach infestations.
- If you have pets, keep them outdoors and/or clean them regularly with hypoallergenic flea prevention.
- If you’re in an area with high amounts of pollen in the air, staying indoors and closing windows and doors can help you avoid exposure.
2. Remove Allergens From the Air
Air purifiers can help reduce the amount of allergens in the air. Also, air conditioners and dehumidifiers can reduce levels of mold, pollen, and dust mites. When using air filtration systems, be sure to follow manufacturer’s instructions, change filters, and clean/reposition fans regularly for the best results.
3. Allergen-Proof Your Home
Allergen-proof covers can be used to protect mattresses, pillows, box springs, and other furniture from allergens. Vacuum cleaners with a HEPA filter can help capture particles that may cause allergic reactions. Certain cleaning products, such as bleach, can also be used to reduce allergen levels in your home.
4. Medications
Medications, such as antihistamines, nasal sprays, and decongestants, can help reduce allergy symptoms and prevent them from happening. Talk to your doctor to find the best medication for you. Some patients may need to take allergy shots, which can reduce the severity of allergic reactions.
5. Allergy Triggers to Avoid
Avoiding known allergens can help reduce allergy symptoms. Some common allergens include pollens, pet dander, dust mites, mold, and latex. Be sure to wear a mask if you must work with any of these substances and to take special precautions if you are near someone who is having an allergic reaction.
