Non-allergic rhinitis is defined as a condition causing abundant chronic watery rhinorrhoea which is not allergic in aetiology. It is a general term having a number of conditions, which include Hormonal rhinitis, Vasomotor rhinitis, Occupational rhinitis, Drug-induced rhinitis, Non-allergic rhinitis with eosinophilia syndrome (NARES). Australia has a particularly high prevalence of allergic rhinitis by global standards. It is the most common chronic respiratory condition in Australia. It affects about 15% of the population, particularly those of working ageA total of 1,107 patients (73%)had AR, whereas 404 (27%) had NAR. AR patients had more severe symptoms and recurrent conjunctivitis, whereas NAR patients had slightly more frequent episodes of recurring headaches as well as olfactory dysfunction. PNIF, blood eosinophil counts and VAS of nasal symptoms were higher in patients with AR.
Commonly, though not always, many patients with non-allergic rhinitis report that cigarette smoke, hairspray, and perfume trigger symptoms. However, in the end, studies are needed in order to determine whether allergies and/or chronic sinusitis are truly present or not before pursuing further treatment that may be unhelpful. Such studies include CT scans of the sinuses to evaluate the presence of a chronic sinus infection as well as allergy testing to determine if allergies are present. If both tests come back normal, one must abandon the diagnosis of chronic sinusitis as well as allergies and consider non-allergic rhinitis as they main culprit. Non-allergic rhinitis can't be cured. But it can be controlled by: Avoiding rhinitis triggers, Using home remedies such as nasal irrigation, Taking over the counter and prescription medications.
