Common Allergies and Allergic Reactions
When allergy hits, the body begins producing antibodies to fight the invading source. Allergic reactions can include hives, coughs and wheezing.
Today in the United States, roughly one in three adults, and one in four children, experience some type of allergic reaction every year. Often triggered by dust and grass, climate changes are lengthening pollen seasons around the world, and causing additional environmental allergies.
When an allergy attack hits, the body begins producing antibodies against the invading source. Antibodies then release allergy-fighting chemicals made naturally in the body, which may cause side effects ranging from hives and constant sniffling to itchy eyes.
Types of Allergies
Seasonal allergies to grass, weeds and pollen may come and go throughout the year. Symptoms vary but may include a stuffy nose, scratchy throat and red eyes.
Cat and dog dander (shedding skin cells) are common causes of allergies, which may cause hives and itching. Microscopic dust mites and dander are insect-like pests that can trigger sneezing and congestion.
Food allergies to gluten or milk for example, may cause cramps, vomiting and tightness in the throat. Allergies to peanuts and shellfish can be extremely dangerous, sometimes resulting in death.
Hidden mold at home, at school or at work may cause allergic reactions and long-term problems in people allergic to mold spores. Symptoms for mold allergies include coughing and watery eyes – but they can be much worse too.
Is it a cold or an allergy?
Colds are viral infections. Allergies are immune system reactions. They share common symptoms and sometimes it’s hard to tell them apart.
Cold symptoms
- Headache, cough, mucus, sore throat, congestion
- Symptoms should lessen every few days
- Over-the-counter medicine may soothe symptoms
Allergy symptoms
- Itchy red eyes, sneezing and sniffling lasting more than 7-10 days
- Deep wheezing and other respiratory issues lasting weeks
- Take prescribed allergy medications and talk to your doctor about allergy testing
When should you go to urgent care for allergies?
Always consult healthcare providers for severe and sudden allergy symptoms. Extreme (or anaphylactic) allergic reactions are life-threatening and need immediate medical help.
Dangerous allergic reactions include:
- Wheezing or severe shortness of breath
- Hoarseness or extreme tightness in the throat
- Tingling in hands, feet, lips or scalp
