• #2 Allergies: Types, Symptoms, Treatment & Management

  https://my.clevelandclinic.org/health/diseases/8610-allergies

  Allergies happen when your immune system mistakenly identifies foreign proteins in pollen, pet dander, medications, food or other substances as something harmful (as if it were a virus or bacteria). Inhaling, eating or touching something you’re allergic to activates mechanisms meant to protect you and flush the allergen out of your system. This causes your symptoms, which can sometimes be life-threatening. […] What to expect when you have allergies depends on what kind they are. Seasonal or pet allergies are generally more likely to cause irritating, but not life-threatening, reactions. Food and drug allergies and bee stings are more likely to cause serious reactions. You’ll probably need to carry an epinephrine injector if you have one of these allergies.

• #3 Hay fever – Symptoms and causes – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/hay-fever/symptoms-causes/syc-20373039

  When someone has hay fever, the immune system identifies a harmless airborne substance as being harmful. This substance is called an allergen. The body produces immunoglobulin E (IgE) antibodies to protect against allergens. When the body comes in contact with an allergen, these antibodies signal the immune system to release chemicals such as histamine into the bloodstream. This causes a reaction that leads to the symptoms of hay fever. […] Hay fever can interfere with enjoyment of activities and cause you to be less productive. For many people, hay fever symptoms lead to missing work or school. […] Hay fever symptoms can keep you awake or make it hard to stay asleep. This can lead to fatigue and a general feeling of being unwell, called malaise. […] Hay fever can worsen symptoms of asthma, such as coughing and wheezing. […] Prolonged sinus congestion due to hay fever may increase your risk of getting sinusitis an infection or inflammation of the membrane that lines the sinuses. […] In children, hay fever often is a factor in middle ear infection, called otitis media.

• #4 A Complete Guide to Allergies – Allergy & Asthma Network

  https://allergyasthmanetwork.org/allergies/

  A person with an allergy has an overactive immune system. When people have an allergy, their immune system reacts to harmless things, such as grass pollen, pet fur, or a specific food. Something that is normally harmless but causes a reaction is called an allergen. […] In people with allergies, the usual way the immune system treats things like pollen, mold, dust mites or animal dander is changed, and the body identifies these as dangerous invaders. Then, your immune system creates a specific IgE antibody to fight it if the allergen enters your body again. […] When you come in contact with the same allergen later, the body is ready to respond with its protective IgE antibodies for that allergen. The antibodies attach themselves to white blood cells called mast cells that line the mucous membrane of the nose, eyes and lungs and cause inflammation. Cilia, the tiny hairs that trap and sweep allergens out of the way, become bogged down with mucus and fluid and allergy symptoms appear.

[…] Allergy symptoms occur when your immune system overreacts to a typically harmless substance such as pollen, dust mites, or foods. When exposed to this substance (known as a trigger or allergen,) your bodys immune system will respond: the immune system will release chemicals such as histamine. histamine and other chemicals will result in the symptoms you experience such as itching, hives or sneezing. This immune system response is called an allergic reaction.

Signs and symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes. Symptom onset is often within minutes following allergen exposure, and can affect sleep and the ability to work or study. Some people may develop symptoms only during specific times of the year, often as a result of pollen exposure. Many people with allergic rhinitis also have asthma, allergic conjunctivitis, or atopic dermatitis. […] The characteristic symptoms of allergic rhinitis are: rhinorrhea (excess nasal secretion), itching, sneezing fits, and nasal congestion/obstruction. […] The symptoms of allergies resemble those of the common cold; however, they often last for more than two weeks and, despite the common name, typically do not include a fever.

  If you’re one of the 50 million Americans who suffers from allergies, your symptoms may bloom when the seasons shift. Itchy, watery eyes, a tickly throat, and a stuffy, runny nose can make you dread springing ahead—and falling back. Likely triggers include tree pollen, grass, mold, and ragweed. […] Whatever the cause, allergies can make you feel miserable. “One aspect of allergies is that you can be really tired or fatigued, so it wipes you out,” says Christina Price, MD, a Yale Medicine allergist and immunologist. The fatigue can cause confusion about the source of your discomfort: Do you have allergies or a cold? It matters because you should treat them differently. […] The severity of your reaction depends on how much of a threat your body perceives an allergen is. Take pollen, for example. “Most people don’t have an immune response to pollen, but a certain percentage of people’s immune systems see it as foreign and dangerous and they treat it like a pathogen or infection,” says Dr. Price.
