Allergies

Millions of individuals worldwide suffer from allergies. Allergies can show themselves in a variety of ways, ranging from seasonal sniffles to severe food responses. Fundamentally, an allergy is an overreaction of the immune system to a normally innocuous chemical. This material is referred to as an allergen because it causes the immune system to release substances like histamines, which cause a variety of symptoms. Allergens are present in our bodies as well as in the environment and food.

• Seasonal Allergies (Hay Fever):

One of the most prevalent forms of allergies, seasonal allergies occur when the immune system reacts to pollen from trees, grasses, and weeds.

• Food Allergies:

Food allergies are immune responses to proteins in certain foods. Common allergens include peanuts, tree nuts, milk, eggs, wheat, soy, fish, and shellfish. Reactions can range from mild itching to life-threatening anaphylaxis.

• Allergic Asthma:

Asthma is a chronic respiratory condition that can be triggered or worsened by allergens such as pollen, mold spores, pet dander, or dust mites.

• Contact Dermatitis:

This type of allergy occurs when the skin comes into contact with allergens like certain metals, plants, or chemicals. It leads to redness, itching, and sometimes blisters at the contact site.

1. Respiratory Symptoms:
   • Sneezing: One of the most common symptoms, triggered by the release of histamines that irritate the nasal passages.
   • Runny or Congested Nose: Histamines cause blood vessels to expand, leading to nasal congestion and a runny nose.
2. Ocular Symptoms:
   • Itchy Eyes: Histamines released in response to allergens can cause intense itching and discomfort in the eyes.
   • Watery Eyes: Increased tear production is a common response to allergens, contributing to watery eyes.
3. Dermatological Symptoms:
   • Skin Rash: Contact with allergens can lead to hives or eczema, presenting as red, itchy rashes on the skin.
   • Swelling: In severe cases, allergic reactions may cause angioedema, characterized by swelling, particularly around the eyes and lips.
4. Gastrointestinal Symptoms:
   • Nausea and Vomiting: In cases of food allergies, the immune response can extend to the gastrointestinal tract, causing nausea and vomiting.
   • Diarrhea: Allergic reactions to certain foods may lead to gastrointestinal distress and diarrhea.
5. Respiratory Distress (Anaphylaxis):
   • Shortness of Breath: Severe allergic reactions can cause the airways to constrict, leading to difficulty breathing.
   • Wheezing: Constricted airways may produce a wheezing sound, indicative of restricted airflow.
6. Systemic Symptoms:
   • Fatigue: Allergic reactions can be physically draining, leading to feelings of fatigue.
   • Malaise: General discomfort and unease may accompany allergic episodes.

• Pollen:

Commonly associated with hay fever, pollen from trees, grasses, and weeds can trigger allergic reactions.

• Common Allergens:

Proteins in certain foods, such as peanuts, tree nuts, milk, eggs, wheat, soy, fish, and shellfish, can induce allergic reactions.

• Mold Spores:

Mold found indoors and outdoors can be a potent allergen, especially in damp environments.

• Medical Products:

Latex, found in medical gloves and certain medical devices, can trigger allergic reactions in sensitive individuals.

• Workplace Exposures:

Certain occupations expose individuals to allergens, such as dust, chemicals, or animal dander, leading to occupational allergies.

• Medications:

Symptom relief for allergies may involve different approaches depending on the severity and type of allergy. A healthcare professional can assess your condition and recommend suitable management strategies tailored to your individual needs.

• Allergen Avoidance:

Avoiding exposure to known allergens is a primary preventive measure. This may involve lifestyle adjustments, such as using air purifiers, keeping windows closed during peak pollen seasons, or adopting hypoallergenic bedding.

• Immunotherapy:

The goal of allergen immunotherapy, sometimes referred to as allergy injections, is to desensitize the immune system by progressively increasing the number of allergens. A doctor may recommend a long-term management plan, which can include specialist referral or allergy support strategies.

• Emergency Medications:

Individuals with severe allergies may be advised by a doctor on how to prepare for unexpected reactions.

While allergies may not be curable, some individuals find that symptoms can be managed through lifestyle adjustments and professional guidance. Reducing exposure to known allergens may help minimise flare-ups.
