4 Best Doctors For Allergies In Dera Ismail Khan

An allergy is a hypersensitive immune response to specific allergens. These substances may trigger allergic reactions if ingested or inhaled. Common allergens include pollen, pet dander, dust mites, insect stings, latex, or certain foods and medications. When your body is exposed to an allergen, the immune system identifies it as a threat and produces immunoglobulin E antibodies. As a result, histamines are released which cause different allergy symptoms.

What are the different types of allergies?

Allergies are categorized into the following types:

• Respiratory Allergies: The allergies caused by pollen, mold spores, or pet dander, affecting your respiratory system are termed respiratory allergies. Allergic rhinitis or hay fever is an example of such allergies. In some people, these allergies also trigger asthma symptoms. 

• Food Allergies: Certain foods such as eggs, milk, soy, wheat, peanut, or shellfish may trigger allergic reactions. Ingesting even a small amount of such foods deteriorates health.  

• Insect Sting Allergies: Some people may develop allergies to bees, wasps, hornets, or fire ant stings. In some cases, severe reactions such as anaphylaxis may occur. 

• Skin Allergies: Certain substances like metal, latex, cosmetics, or poison ivy may cause allergic skin symptoms such as itchiness, hives, or skin rash. 

• Drug Allergies: Antibiotics such as penicillin, nonsteroidal anti-inflammatory drugs, or anticonvulsants may cause allergies in some people. 

• Occupational Allergies: Work environments also expose individuals to allergens including chemicals, dust, or animal dander, leading to occupational allergies.

• Pet Allergies: Contact with pet dander, saliva, or urine may trigger allergic symptoms in some folks.
