Somebody asked this question on Facebook & I was interested to see that quite a few people did have issues with it.
I have had issues for the last two years that was being attributed to me having sinus problems. I have been under a specialist Taste & Smell ENT clinic - there are only 3 in the whole of the country!
However it would be interesting to see if it is a problem connected to auto immune conditions.
Some people have had it attributed to the medication we are on but I don't think that theory is conclusive.
There is a fairly new group supporting people with taste & smell issues called The Fifth Sense
Although taste & smell is one of the five senses very little credit is given to the impact that it has on people's lives.
If we had problems with hearing & sight we would be referred to the appropriate doctor, however this doesn't happen with taste & smell.
