Sinusitis patients often first complain about a lack of smell and taste whereas allergic rhinitis patients, while blocked up, will normally be able to smell and taste, says Dr Jessica Tattersall, general allergist and medical rhinologist in Sydney.
But there are some important co-morbidities to consider among allergic rhinitis patients, one of them being asthma, she says.
“If you have asthma you have an 80% chance of having allergic rhinitis and if you have allergic rhinitis, there’s a 40-60% chance you also have clinical or sub-clinical asthma,” Dr Tattersall says.
Another indication is allergic conjunctivitis, which also often occurs with allergic rhinitis.
