Your body may usually react to harmless substances which include food, pets, pollen, mold and latex, drugs, and insects. This is your immune system responding to foreign substances, which are called allergens.
Symptoms of having an allergic reaction are the following but not limited to runny nose, itching, rashes, swelling or fatigue.
Allergies usually vary from minor to severe. Anaphylaxis is a serious, life-threatening response that can lead to difficulty of breathing, lightheadedness and loss of consciousness. If you’re having these symptoms, seek medical help immediately. Doctors identify allergies by using skin and blood testing.
Common types of allergens include:
- Animal products. These include pet dander, dust mite waste, and cockroaches.
- Drugs. Penicillin and sulfa drugs are common triggers.
- Foods. Wheat, nuts, milk, shellfish, and egg allergies are common.
- Insect stings. These include bees, wasps, and mosquitoes.
- Mold. Airborne spores from mold can trigger a reaction.
- Plants. Pollens from grass, weeds, and trees, as well as resin from plants such as poison ivy and poison oak, are very common plant allergens.
- Other allergens. Latex, often found in latex gloves and condoms, and metals like nickel are also common allergens.
Preventive measures on allergic reaction is to stay away from triggers that may cause reactions. However, if you are caught in the middle of an allergic reaction, medications like antihistamines can control the symptoms. These are available over the counter or prescribed depending on the severity of your allergies.
Some allergic reactions may be so severe that may be considered a medical emergency. It is recommended to know allergic reaction first aid during emergency situations.
