Allergies reaction happens when the immune system becomes very sensitive to certain things like food, pollen, medications, bee stings, and more. Being around these things, called allergens, can cause symptoms like swelling and hives. An allergen is something that triggers an allergic reaction. Many everyday things can be allergens, even if they’re harmless to most people. But if your immune system reacts badly to it, anything can be an allergen. Every year, more than 50 million people in the United States have allergic reactions. These reactions can cause symptoms like swelling. If the swelling affects the airways, it can be-life threatening. So in this article, we’ll tell you about the things that can make allergies more likely, the symptoms they cause, and how they can be treated. For more research you can also visit Cleveland Clinic.
What is an Allergy?
Allergies are when your body reacts badly to something it’s sensitive to. This can cause symptoms like sneezing, itching, or swelling. However, anything can be an allergen if the immune system has a specific type of adverse reaction to it. The immune system’s job is to fight that could harm the body. If someone has an allergy to something, their immune system mistakenly thinks that thing is harmful and tries to get rid of it.
What are the Types of Allergies?
Different kinds of allergy are classified to denote cause, severity and possible management and prevention. These include:
Type 1:
This is also called immediate or anaphylactic-type reactions. It can happen because of things like pollen, certain foods, medications, and insect stings.
Type 2:
This involves special antibodies known as Immunoglobulin G (lgG) and igM. They attach to cells and destroy them. This reaction happens after an organ transplant when the body doesn’t recognize the transplanted organ as its own.
Type 3:
This is the type of reaction where an immune complex forms. These complexes happen when an antibody binds to an antigen. This sets off a series of reactions in the body that can damage nearby tissues. Conditions like glomerulonephritis and systemic lupus erythematosus (lupus, SLE) are examples of this type of reaction.
Type 4:
Delayed or cell-mediated reactions are controlled by specific immune cells known as T-cells lymphocytes. It takes some time for these T cells to trigger an allergic response, ranging from a few hours to a few days. Examples of this type of reaction include contact dermatitis, like rashes caused by poison ivy.
What are the Symptoms of Allergies?
Symptoms of allergies can vary depending on what someone is allergic to and how severe their reaction is. So common symptoms include:
- Sneezing
- Runny or stuffy nose
- Itchy or watery eyes
- Coughing
- Wheezing
- Shortness of breath
- Skin rash
- Swelling of the lips or face
- Nausea
- Vomiting
- Fatigue
Everyone will experience all of these symptoms, and the severity can vary from person to person. In severe cases, allergies can lead to anaphylaxis, a life-threatening reaction that requires immediate medical attention. Below are some triggers and the symptoms they may cause in people with an allergy.
Dust and Pollen:
- A blocked and congested nose
- Itchy eyes and nose
- Runny nose
- Swollen eyes
Foods:
- Vomiting
- Swollen tongue
- Tingling in the mouth
- Swelling on the lips, face, and throat
- Stomach cramps
- Rectal bleeding mainly in children
- Itchiness in the mouth
- Diarrhea
Insect Stings:
- Wheezing
- Significant swelling at the site of the sting
- A sudden drop in blood pressure
- Itchy skin
- Shortness of breath
- Restlessness
- Hives, or a red and very itchy rash that spreads across the body
- Dizziness
- Cough
- Chest tightness
Medications:
- Wheezing
- Swelling of the tongue, lips, or face
- Rash
- Itchiness
- If the symptoms become severe, anaphylaxis.
Anaphylaxis Symptoms:
Anaphylaxis is the most severe type of allergic reaction, and its medical emergency because it can be life-threatening. It can be happy very quickly, with symptoms showing up within minutes or hours of being exposed to the thing someone is allergic to. So research shows that anaphylaxis usually affects the skin and breathing system the most. Some symptoms of anaphylaxis include:
- Hives, flushing and itching
- Trouble breathing
- Wheezing
- Swelling
- Low blood pressure
- Cholesterol
- Changes in heart rate
- Feeling dizzy or fainting
- Losing consciousness
It’s really important to recognize these symptoms so you can get treatment right away.
What are the Causes of Allergies?
Allergies are caused by the body’s immune system reacting to substances it mistakenly identifies as harmful, even though they’re harmless to most people. So these substance, called allergens can vary widely and may include:
- Dust mites
- Pet dander
- Pollen
- Mold
- Certain foods
- Medications
- Latex
- Inhalants
When someone has an allergic reaction, the allergens attach to special antibodies in the body called immunoglobulin E (lgE). These antibodies help the body fight off foreign and potentially harmful substances. After the allergens attach to lgE, certain cells like mast cells release chemicals that cause the symptoms of the allergic reaction. One of these chemicals is histamine. Histamine makes the muscles in the airways and blood vessels tighten. It also tells the lining of the nose to make more mucus.
What are the Risk Factors of Allergies?
Certain factors can increase the likelihood of developing allergies. These risk factors include:
- Family history
- Genetics
- Environmental exposure
- Early childhood factors
- Other allergic conditions
- Smoking exposure
- Environmental pollution
- Occupational exposure
- Dietary factors
- Psychological Stress
These factors can increase the risk of developing allergies, not everyone with these risk factors will develop allergies, and individuals without these risk factors can still develop allergies.
What is the Diagnosis of Allergies?
The diagnosis of allergies typically involves a combination or medical history, physical examination and specific tests. Here are common methods used for diagnosing the allergies:
- Medical history
- Physical examination
- Allergy testing, such as: (skin test, blood test, skin prick test, patch test, elimination diet)
- Challenge test
- Nasal endoscopy
- Spirometry
Based on the results of these diagnostic tests and examinations, doctors can determine the specific allergens causing allergic reactions and develop an appropriate management plan, which may include allergen avoidance, medications, immunotherapy, or lifestyle modifications.
What is the Treatment of Allergies?
The treatment of allergies aims to alleviate symptoms, reduce the body’s immune response to allergens, and prevent allergic reactions. Treatment options may vary depending on the type and severity of allergies, as well as individual factors. Here are common approaches to treating allergies:
Allergens Avoidance: Avoiding exposure to known allergens is often the first step in managing allergies. This may include:
- Keeping the indoor environment clean and free of dust, pet dander, and mold.
- Using allergens-proof covers for bedding and pillows.
- Minimizing outdoor activities during high pollen seasons.
- Avoiding foods or medications known to trigger allergic reactions.
Medications:
- Antihistamines
- Decongestants
- Nasal corticosteroids
- Bronchodilators
- Epinephrine auto injector
Immunotherapy:
Also known as allergy shots or allergy desensitization, immunotherapy involves gradually exposing the body to increasing doses of allergens to reduce the immune system’s sensitivity and allergic response over time. This treatment is typically recommended for individuals with severe allergies or those whose symptoms are not well-controlled with medications.
Allergy Medications:
- Eye drop
- Topical treatment
Lifestyle Modifications: Making certain lifestyle changes can help manage allergies and reduce exposure to triggers. These may include:
- Using air purifiers or filters to remove allergens from indoor air.
- Practicing good hygiene, such as regular hand washing and bathing pets.
- Wearing protective clothing and gear, such as gloves and mask, when exposed to potential allergens.
- Following a healthy diet and staying hydrated to support overall immune health.
It’s important for individuals with allergies to work closely with doctors to develop a personalized treatment plan tailored to their specific needs and allergy triggers. Additionally, regular monitoring and follow-up appointments may be necessary to assess treatment effectiveness and make necessary adjustments. It is a severe and potentially life-threatening allergic reaction that requires immediate medical attention. The treatment for anaphylaxis typically involves the following steps:
- Epinephrine injection
- Call emergency services
- Positioning
- Monitor vital signs
- Additional medications
- Supportive care
- Hospitalization
- Follow-up care
At the risk of anaphylaxis, especially those with known allergies to certain foods, insect stings, medications, or other allergens to carry an epinephrine and auto-injector with them at all times and be prepared to use it in case of an emergency. Additionally, educating family members, caregivers, and close contacts on recognizing the signs and symptoms of anaphylaxis and administering epinephrine can be life –saving.
What is the Prevention of Allergies?
Preventing allergies and taking precautions to minimize exposure to allergens are important steps in managing allergic reactions. So here are some strategies for prevention and precautions:
Identify Triggers:
Work with doctors to identify specific allergens that trigger allergic reactions. So this may involve allergy testing, medical history review, and observation of symptoms.
Allergens Avoidance:
- Once allergens are identified, take steps to minimize exposure to them. This may include:
- Keeping the indoor environment clean and free of dust, pet dander, and mold.
- Using allergens-proof covers for bedding and pillows.
- Minimizing outdoor activities during high pollen seasons.
- Avoiding foods or medications known to trigger allergic reactions.
- Washing hands and bathing pets regularly to reduce exposure to allergens.
Food Allergy Management:
- Read food labels carefully to identify potential allergens.
- Inform restaurants and food service providers about food allergies when dining out.
- Carry an epinephrine auto-injector if you have a history of severe food allergies.
Medications Management:
- Take prescribed allergy medications as directed by a healthcare provider.
- Keep medications on hand, especially during allergy season or when traveling.
Personal Protection:
- Wear protective clothing such as gloves and masks when cleaning or working with potential allergens.
- Use insect repellent and protective clothing to prevent insect stings.
Allergy Immunotherapy:
Consider allergy immunotherapy if allergens avoidance and medications are not effective in controlling allergic symptoms. So allergy immunotherapy can help desensitize the immune system to specific allergens over time.
Emergency Preparedness:
- Carrying an epinephrine auto injector if prescribed.
- Educating the family members, caretakers, and friends on recognizing the signs and symptoms of allergic reactions and how to administer epinephrine.
- Having an anaphylaxis action plan in place, including steps to take in case of an allergic emergency.
Regular Follow Up:
- Schedule regular follow up appointments with your doctor to monitor allergic symptoms, adjust treatment plans as needed, and discuss any new development or concerns.
- By implementing these prevention and precautions measures, individuals with allergies can better manage their condition and reduce the risk of experiencing allergic reactions.
