  • Hay Fever
  • House Dust Allergy
  • Latex Allergy
  • Mold Allergy
  • Pet Allergy

Signs and Symptoms

The dust and pollen allergies are caused due to airborne particles causing symptoms affecting eyes, nose, and lungs. In case of hay fever otherwise known as allergic rhinitis causes irritation of nose, redness of eyes, sneezing and itching.

In some cases the allergens when inhaled can cause asthmatic symptoms leading to narrowing airways otherwise known as bronchoconstriction and excessive mucus production in the lungs, difficulty breathing (dyspnea), wheezing and cough.

Few people are also allergic to food, insect stings and medications such as penicillin, antibiotics and aspirin. Food allergy symptoms usually comprise of abdominal pain, bloating, vomiting, diarrhea, itchy skin, and swelling of the skin during hives. Though they rarely cause asthmatic problems or rhinitis

Medicines, insect’s stings and antibiotics can cause anaphylaxis which affects multiples organ systems such as respiratory system, circulatory system, and also digestive systems.

The severity rate of the allergy can cause cutaneous reactions, bronchoconstriction, edema, hypotension, coma, and even fatality. It can happen immediately or at times there is a delay for reaction to be triggered.

Causes of Allergies

Food allergies are caused due the patient’s sensitivity to peanuts, while other allergens can be tree nuts, pecans, pine nuts, and pistachios. Some patients are also allergic to seeds such as sesame seeds and poppy because they contain oil and proteins that can trigger an outburst.
