Why we get hay fever, how to know its hay fever and what we can do to treat hay fever - all answered by a leading consultant amid high pollen warnings
Hay fever sufferers are among those being warned ahead of high pollen counts rolling in over the coronation weekend.
"So children of parents with allergies are more likely to have allergies themselves. But that's not enough. And there's quite a lot of research going on as to why allergies are increasing. "One of the most commonly quoted theories is what we call the hygiene hypothesis. We see that the prevalence of allergies is much higher in developed countries compared to developing countries.
When we get hay fever can also depend on what kind of pollen sets a person off with symptoms. The various pollen types can occur at different times of the year, with grass pollen being the kind 'most people' are allergic to, according to the expert. "Normally having ocular symptoms is one of the things that allows you to distinguish if you're in doubt of could it be cold, or is it an allergy?" says Dr Marinho. "If you've got a cold, there might not be so much itching, it's more of a blocked and drippy nose. If your eyes are involved and get red, watery, itchy and irritated - that's more likely to be allergic.
Lifestyle changes Dr Marinho is reminding people that there are basic lifestyle changes hay fever sufferers may not have considered which could make a big difference when it comes to their symptoms. "There's nasal filters and some barrier methods," Dr Marinho adds. "I think they can be cosmetically acceptable, and they are a barrier that will stop the pollen from going into your nose.
"Lots of patients will think steroids are a problem and they'll have lots of side effects. That's not true. Nasal steroids act on the nose. This is why we want a nasal spray rather than telling patients to take tablets, so that we just use the drug that goes in the organ that we need to treat. It doesn't go anywhere else.Nasal sprays can provide relief - and there are some myths about the steroids that need debunking, according to Dr Marinho.
