onion allergy

Dust mite particles are often found in pillows, mattresses, carpeting and upholstered furniture. They float into the air when anyone vacuums, walks on a carpet or disturbs bedding and they settle once the disturbance is over.

Dust mites are a common cause of asthma in children.

A house does not need to be visibly dirty to trigger a dust mite allergy reaction. The particles are too tiny to be seen and often cannot be removed using normal cleaning procedures. In fact, a vigorous cleaning can make an allergic person’s symptoms worse.

Cockroaches
Cockroaches live in all types of buildings and neighborhoods. Some people develop allergy symptoms when they are around cockroaches. Tiny particles from the cockroach are a common component of household dust and may be the true cause of a dust allergy.

Mold
Mold is a fungus that makes spores that float in the air. When people with a mold allergy inhale the spores, they get allergy symptoms. There are many different kinds of mold—some kinds you can see, others you can’t.

Molds live everywhere—on logs and on fallen leaves, and in moist places like bathrooms and kitchens. Tiny mold particles and spores are a common component of household dust doxycycline tablet and may be the true cause of a dust allergy.

Pollen
Pollen comes from trees, grasses, flowers and weeds. People can be allergic to different types of pollen. For instance, some people are allergic to pollen from only beech trees; others are allergic to pollen from only certain kinds of grasses. Pollen is a common component of household dust and may be the true cause of a dust allergy.

Animal hair, fur and feathers
Pets can cause problems for allergic patients in several ways. Their dander (skin flakes), saliva and urine can cause an allergic reaction, especially when combined with household dust. In households with birds, feathers and bird droppings can also become embedded in household dust and cause problems for people who are allergic to them.

Treatment
If you think you may have an allergy to any of the components of house dust, see an allergist. To pinpoint the cause of your symptoms, the allergist will ask detailed questions about your work and home environments, family medical history, frequency and severity of symptoms and exposure to pets and other possible triggers.

Sometimes the medical interview will reveal a likely culprit—for instance, a girl who gets a stuffy nose every time she plays with a friend’s cat might have an allergy to cats or to the dust infused with cat hair in her friend’s house.

Often an allergist will need to conduct a skin test to determine exactly what is triggering an allergic reaction.

Skin tests involve using a small, sterile probe to prick the skin with extracts from common allergens, such as tree pollen and pet dander, and observing the reaction. A positive reaction (a raised welt with redness around it) may indicate that you are allergic to that substance. Occasionally, your allergist may order a blood test and a skin test to confirm an allergy.

After a dust allergy is identified, your allergist will recommend one or more of the following treatments:

Medications
Allergy shots (subcutaneous immunotherapy)
Tablets (oral immunotherapy)
Changes to your household routineIt’s more common to fear an insect sting than to actually be allergic to one. An allergist is an expert who can explain the difference between an allergic reaction and a normal reaction, thus reducing anxiety and preventing unnecessary medical expense.

Thousands of people enter hospital emergency rooms or urgent care clinics every year suffering from insect stings. It has been estimated that potentially life-threatening allergic reactions occur in 0.4% – 0.8% of children and 3% of adults. At least 90 – 100 deaths per year result from insect sting anaphylaxis.

The majority of insect stings in the United States come from wasps, yellow jackets, hornets and honeybees. The red or black imported fire ant now infests more than 260 million acres in the southern United States, where it how to buy wellbutrin has become a significant health hazard and may be the number one agent of insect stings.

Insect Sting Allergy Symptoms
Pain
Redness
Swelling (in area of sting and sometimes beyond)
Flushing
Hives
Itching
Anaphylaxis (less common), a potentially life-threatening reaction that may impair breathing and can cause the body to go into shock
Insect Sting Allergy Management and Treatment
Avoid insects.
Immediately inject epinephrine (adrenaline) if symptoms of anaphylaxis develop.
Consider allergy shots (immunotherapy).
Symptoms
The severity of an insect sting reaction varies from person to person. A normal reaction will result in pain, swelling and redness confined to the sting site. You can disinfect the area (washing with soap and water will do) and apply ice to reduce the swelling.

A large local reaction will result in swelling that extends beyond the sting site. For example, a sting on the forearm could result in the entire arm swelling. Although alarming in appearance, this condition is often treated the same as a normal reaction. An unusually painful or very large local reaction may need medical attention. Because this condition may persist for two to three days, antihistamines and corticosteroids are sometimes prescribed to lessen the discomfort.

Fire ants, yellow jackets, hornets and wasps can sting repeatedly. Honeybees have barbed stingers that are left behind in their victim’s skin. These stingers are best removed by a scraping action, rather than a pulling motion, to avoid squeezing more venom into the skin.

Almost everyone stung by fire ants develops an itchy, localized hive or lump at the sting site, which usually goes down within 30 to 60 minutes. This is followed by a small blister within four hours. This usually appears to become filled with pus-like material by eight to 24 hours. However, what is seen is really dead tissue, and the blister has little chance of being infected unless it is opened. When healed, these lesions may leave scars.

Treatment for fire ant stings is aimed at preventing secondary bacterial infection, which may occur if the pustule is scratched or broken. Clean the blisters with soap and water to prevent secondary infection. Do not break the blister. Topical corticosteroid ointments and oral antihistamines may relieve the itching associated with these reactions
