What is
mixed rhinitis?
There
are many patients who think that they have nasal allergies. They complain of
chronic nasal congestion, runny nose, postnasal drainage, sinus congestion and
headaches. Their nasal and sinus symptoms are usually set off by exposure to
various triggers such as changes in the weather, certain perfumes,
cigarette smoke, changes in temperature, strong moldy smells and sometimes with
exposure to allergens such as dust, cats, dogs, and pollens. These patients
have both allergic and non-allergic rhinitis which means that they have both
allergic and irritant triggers.

Is there such a thing as a hypo-allergenic pet?
It is amazing how much people claim that there is such a thing as a hypoallergenic pet. This is truly a myth. A lot of people think that pet allergies are caused by the dog’s or cat’s fur or hair, when in reality it is caused by a protein that is in the pet’s saliva or urine. This allergenic protein sticks in the pets dander, or hair and gets circulated into the environment.People who develop pet allergies usually have the genetic predisposition to become allergic. If you have one parent who has some form of allergies such as allergic rhinitis, asthma, or eczema there is a 30% chance that one will become allergic. If both parents have some form of allergies, there is a 50% chance of developing allergies
There is usually a period when the individual does not have the pet allergy. It is only after a significant time of exposure that his body starts having the immune reaction to develop allergic antibodies or IgE antibodies that causes one to develop allergy symptoms. Once he or she has enough allergic antibodies, then that individual will start having allergy symptoms when exposed to the pet. These allergy symptoms would include sneezing, itchy eyes, itchy nose, runny nose as seen in someone with allergic rhinitis and conjunctivitis; wheezing, shortness of breath and coughing, as seen in someone with allergic asthma. They may also develop hives when the pet allergen present in saliva or other animal secretions come in contact with their skin causing allergic urticaria.
