How do your allergies develop?

How do our bodies mistake otherwise harmless substances for potential dangers and cause the unpleasant, and sometimes even fatal, symptoms of allergy?
From the mother anxiously watching for signs of wheezing the first time her child eats peanut butter to the retiree’s sudden reaction to shellfish, allergies can strike at any point during our lives.
Allergens, or molecules with the potential to cause allergy, are everywhere in our environment.
When the body mistakes one of these substances as a threat and reacts with an immune response, we develop an allergy.
And what causes the symptoms that many are so familiar with?
This is called a Type 1 immune response, and the cell type at the heart of this process is the regulatory T cell.
When friend becomes foe That being said, in some individuals, the body’s immune cells see the allergen as a threat, and a pro-inflammatory response occurs as a result.
This is called a Type 2 immune response, and a different class of T cell appears on the scene: T helper type 2 cells.
The first exposure to an allergen that results in a Type 2 immune response is called allergic sensitization.
Our bodies can react by developing eczema (atopic dermatitis), hay fever (allergic rhinitis), allergic asthma, food allergies, or anaphylaxis, which is a severe and potentially deadly allergic reaction.

5 things to know about fall allergies

5 things to know about fall allergies

Fall allergies are coming, be prepared.
Dr. Jeffrey Culp, an allergist with Wilmington Health, said spring allergens include tree and grass pollen while fall sufferers struggle with mold and weeds. A secondary fall allergy can also be dust mites.
But Culp said this will just let in mold spores and ragweed pollen, which will only lead to worsening symptoms. The first rule of dealing with fall allergies is avoidance, he said.
Keep windows and doors closed and run the air conditioning, especially in the car. Change air filters regularly and use a dehumidifier to keep mold spores down.
Avoid drying clothes on an outdoor clothing line and check pollen counts daily either online or in the newspaper.
Decongestant sprays can wear off quickly, allowing nasal swelling to come back worse.

Feeling allergy symptoms? Blame Hurricane Irma, some doctors say

Feeling allergy symptoms? Blame Hurricane Irma, some doctors say

Feeling allergy symptoms? You can blame Hurricane Irma for that.
Autumn is the second-worst time of year for allergic reactions in Florida, following the spring blooming season, said Dr. Richard Lockey, a Joy McCann Culverhouse Chair in allergy and immunology at the University of South Florida’s College of Medicine. Ragweed and mold are the most common sources of allergies in the fall weather, though prolonged grass and pollen often play a role at the end of summer as the season changes. “I’m not sure we can blame the hurricane for the high pollen count right now, it happens every fall. This is just the time of year when weeds are pollinating. But maybe there’s more mold this year because of the rainy, humid summer we had.”
That long rainy season has butted up against a very active hurricane season this year, which created a slightly unusual, highly concentrated period for pollen and mold that could make just about anyone itchy and sneezy, explained Dr. Juan Guarderas, who specializes in allergy and immunology at the University of Florida.
Then a high-pressure system moved into the area, bringing the dry weather with it,” Guarderas said.
The dry air is beautiful and fresh, but you invite pollen in with the windows down.”

Alpha-gal allergy: What you need to know

Alpha-gal allergy: What you need to know

Alpha-gal allergy is a condition more commonly known as red meat allergy.
An alpha-gal allergy can cause a person to have anaphylactic and hypersensitivity reactions when they eat meat.
The term alpha-gal is short for galactose-alpha-1, 3-galactose, a carbohydrate molecule that can cause an allergic reaction in people with an alpha-gal allergy.
Cetuximab contains the same alpha-gal sugar as meat, although the association was not made with tick bites until Platts-Mills himself was later bitten by ticks and developed the allergy.
Symptoms Most people discover they have an alpha-gal allergy after eating red meat.
Symptoms do not necessarily occur every time the person eats red meat.
Often a doctor or allergist will ask: what and how much the person ate before the reaction how long it took for symptoms to develop what symptoms occurred and how long they lasted Characteristics of red meat allergies differ from other allergies, as people do not usually experience symptoms until at least 2 hours after eating red meat.
In this case, all mammal meats should be avoided.
The first-line treatment for the serious reactions of anaphylaxis is epinephrine, which is available on prescription as an auto-injector.
If people live in an area where Lone Star ticks are prevalent, there are ways to avoid getting bitten.

Itchy gums: Causes, relief, and prevention

Itchy gums: Causes, relief, and prevention

What are the possible causes, and are itchy gums an early warning sign that can help prevent other health problems?
Less common causes of itchy gums include: teething in younger children teething in adults between the ages of 17 and 21 when the wisdom teeth usually come through tooth abscesses Poor dental hygiene is the underlying reason for many cases of itchy gums because the teeth and gums are not kept clean enough, and plaque builds up.
Options for treatment and relief There are a few simple things that people can do at home straight away to relieve gum itching and irritation: brushing teeth, flossing, and using an antibacterial mouthwash rinsing the mouth with a saltwater solution taking an over-the-counter antihistamine if itching has been caused by an allergy A person should see their dentist if itching persists or if other symptoms are present.
When to see a doctor or dentist It is important to see a dentist if symptoms persist, as the first stage of gum disease or gingivitis can usually be controlled and treated easily.
If mouth injuries or bruxism cause itchy gums, wearing a customized mouth guard that prevents teeth grinding is likely to be the best option for preventing further damage to the teeth and gums.
Prevention The most important way to prevent itchy gums, and the problems that can be associated with them, is to keep teeth and gums clean.
Smoking can negatively affect oral health, including staining teeth or slowing down the healing process.
Hormonal changes, new medication, or an allergic reaction can cause itchy gums.
If someone is concerned or has symptoms that last more than a few days after treatment at home, they should consult a dentist.
Teeth often get more attention than gums, but looking after gums by brushing and flossing regularly and keeping an eye on any changes or irritation, is key to good overall oral health.
