Allergic rhinitis – what are the cause of Allergic rhinitis? Part 2

Allergic rhinitis - a guide

Allergic rhinitis – a guide

Allergic rhinitis is caused by an allergic reaction to an allergen, such as pollen, dust and certain animals.

Oversensitive immune system

If you have allergic rhinitis, your immune system – your natural defence against infection and illness – will react to an allergen as if it were harmful.

If your immune system is oversensitive, it will react to allergens by producing antibodies to fight them off. Antibodies are special proteins in the blood that are usually produced to fight viruses and infections.

Allergic reactions don’t occur the first time you come into contact with an allergen. The immune system has to recognise and “memorise” it before producing antibodies to fight it. This process is known as sensitisation.

After you develop sensitivity to an allergen, it will be detected by antibodies called immunoglobulin E (IgE) whenever it comes into contact with the inside of your nose and throat.

These antibodies cause cells to release a number of chemicals, including histamine, which can cause the inside layer of your nose (the mucous membrane) to become inflamed and produce excess mucus. This is what causes the typical symptoms of sneezing and a blocked or runny nose.

Common allergens

Allergic rhinitis is triggered by breathing in tiny particles of allergens. The most common airborne allergens that cause rhinitis are described below.

House dust mites

House dust mites are tiny insects that feed on the dead flakes of human skin. They can be found in mattresses, carpets, soft furniture, pillows and beds.

Rhinitis isn’t caused by the dust mites themselves, but by a chemical found in their excrement. Dust mites are present all year round, although their numbers tend to peak during the winter.

Pollen and spores

Tiny particles of pollen produced by trees and grasses can sometimes cause allergic rhinitis. Most trees pollinate from early to mid-spring, whereas grasses pollinate at the end of spring and beginning of summer.

Rhinitis can also be caused by spores produced by mould and fungi.

Animals

Many people are allergic to animals, such as cats and dogs. The allergic reaction isn’t caused by animal fur, but flakes of dead animal skin and their urine and saliva.

Dogs and cats are the most common culprits, although some people are affected by horses, cattle, rabbits and rodents, such as guinea pigs and hamsters.

However, being around dogs from an early age can help protect against allergies, and there’s some evidence to suggest that this might also be the case with cats.

Work-related allergens

Some people are affected by allergens found in their work environment, such as wood dust, flour dust or latex.

Who’s most at risk?

It isn’t fully understood why some people become oversensitive to allergens, although you’re more likely to develop an allergy if there’s a history of allergies in your family.

If this is the case, you’re said to be “atopic”, or to have “atopy”. People who are atopic have a genetic tendency to develop allergic conditions. Their increased immune response to allergens results in increased production of IgE antibodies.

Environmental factors may also play a part. Studies have shown certain things may increase the chance of a child developing allergies, such as growing up in a house where people smoke and being exposed to dust mites at a young age.

Millions of us cutting out everything from gluten and dairy to sugar and fat….but how many of us really need to?

Millions of us are cutting out different foods and ingredients from our diets, without any medical guidance to do so.

That’s according to new research released today which shows that almost one in ten have eliminated dairy from their diet – half of those based on their own self-diagnosis, slightly less wheat – more than 40% having self-diaganosed an intolerance, and a similar number gluten – with half of those having made the decision based on their own knowledge.

Furthermore, following the war on sugar in the last two years, one in five of us have eliminated it from our diets, while one in six have ditched fat.

The study by Nutricentre also asked respondents what other measures they have taken to improve their health and or lose weight in the last two years, with a third having tried eating smaller portions, one in six skipping meals and a similar number skipping breakfast.

More than one in 20 have gone on a juice diet, while slightly less have tried weight management classes and soup diets, with some having gone vegetarian and some vegan.

But do these measures actually work? And what do you need to know if you are set on cutting out certain foods in 2016?


Recent research suggests:-

• As many of us continue on with our new year health kicks, a new study released today looks at the trend for eliminating food groups from our diets as a fix-all solution to weight and health issues

• Almost one out of ten say they have cut out dairy in the last two years, with similar numbers having eliminated gluten and wheat

• More than 40% who have eliminated those food groups have done so after self-diagnosis

• With the war on sugar one of the biggest health stories of the last year, it’s no surprise that more than a fifth have cut out sugar, while one in six have got rid of fat in their diet

• But could the trend for cutting things from our diet without medical advice to do so, be unnecessary?

So Patient Talk interviewed Shona Wilkinson, a leading nutritionist, to get the facts straight!

PatientTalk.Org – What are the common food groups being eliminated and why? And is the overall effect a positive one?

Shona Wilkinson- Nutricentre has done a study on over 2000 people, and we’ve actually seen that about 1 in 10 people are cutting out a common food group. These seem to really be wheat, dairy, fat, and sugar, as the predominant ones. So sometimes this can be necessary, and sometimes it can’t. So we just have to be a bit careful if were cutting out whole food groups from our diet, to make sure that were not cutting out nutrient groups as well.

PatientTalk.Org- Is it really possible to cut out fat and sugar from a diet given basic chemistry?

Shona Wilkinson- Probably not. And I don’t know quite why you’d want to cut them totally out of your diet. Why would you want to cut out fat from your diet? This was a message that was going around in the 70s and still seems to be hanging on out there at the moment, so no we don’t want to cut fat out of our diet. Sugar, yes it’s not great for us, but again we don’t want to cut it totally out of our diet. And as soon as you cut something out of your diet, the one thing you can guarantee is that you have real cravings for it, so don’t cut it totally out of your diet, we’re talking about reducing it.

PatientTalk.Org- And how much of it is intolerance related?

Shona Wilkinson -As far as the wheat and dairy is concerned, quite a lot of it. So talking about wheat, quite often people when they have wheat in their diet it can give them digestive problems, so it could be cramping, it could be diahrrea, it could be constipation, quite often a lot of bloating as well. So that can be an intolerance. As far as dairy is concerned, common side effects of having dairy are usually kind of mucus related, a blocked nose, blocked air passages, that kind of thing.

PatientTalk.Org- Okay. What is the difference between an allergy and intolerance?

Shona Wilkinson- There’s a big difference between an allergy and an intolerance, so an example would be, being a celiac. A celiac is someone who has got an auto immune disease and cannot have gluten in their diet. So that’s an actual allergy. The difference there would be someone who gets digestive problems after they’ve had gluten. So rather than it being very severe it could be just a bit of bloating. So they are very two distinct different things.

PatientTalk.Org – So in terms of severity, an allergy is a way more severe problem than an intolerance?

Shona Wilkinson- Absolutely and it can in some cases be life threatening.

PatientTalk.Org – Why has gluten intolerance increased in the last few years?

Shona Wilkinson- Yes gluten intolerance has seemed to increase in the last few years and there’s two schools of thought about this. Partly because one reason could be its quite trendy at the moment to follow a gluten free diet. The other reason is purely the amount of gluten we have in our diets nowadays. So we may have toast or cereal for breakfast, followed by a sandwich or baguette or some sort for lunch, followed by a pasta meal in the evening. That’s quite a common diet for a lot of people nowadays, and if you think about it that’s wheat, wheat, wheat for every single meal, and it’s just becoming too much for our bodies to deal with. So if you’re in that kind of situation, it’s just a matter of reducing your intake, or perhaps cutting out of your diet for 12 weeks and then slowly reintroducing it at a steady slow level and letting your body let you know what is the amount it can deal with every day.

PatientTalk.Org – What is the difference between celiac and gluten intolerance?

Shona Wilkinson – yes so celiac is an actual auto immune disease. It’s medically recognized and it can be life threatening. An intolerance is when you get slight digestive conditions after eating wheat containing food. So they are very different, one is a medical condition and one is more an intolerance that you just can’t cope with it as much.

PatientTalk.Org – What is a juice diet and how would it work?

Shona Wilkinson – Yeah, the juice diet again is quite trendy at the moment, especially it being January. Basically its people living for probably usually about 7 days, just purely on juices. We have to be very careful about this because it’s not really training you on how to eat healthily so by the end of your juice diet you can just go back to your normal unhealthy eating habits. But also with juices, they tend to be predominately fruit, which can be high sugar content. So not the healthiest of thing, not something a nutritionist usually recommends.

PatientTalk.Org- Is there much evidence of self-diagnosis? How is it done? What are the dangers, if any, associated with self-diagnosis?

Shona Wilkinson – Yes the study done by Nutricentre shows that 40% of people have eliminated food groups from their diet just on self-diagnosis. This is usually just by monitoring their symptoms, some people keep a food diary and monitor any symptoms they’ve got after they’ve eating a certain type of food. A lot of people reading things on the internet. There aren’t really any dangers of this unless you’re cutting out a food group and not getting the nutrients that you need. So for example if you become a vegan, then you have to be careful that you’re still getting the nutrients that you need there. Self-diagnosis can also be done through a blood test, which is quite an accurate way to see if you’ve got a food intolerance. There’s lots of other tests out there which I wouldn’t necessarily recommend, but a blood test is the most accurate.

PatientTalk.Org – Does this trend suggest a decrease in confidence in traditional health care providers?

Shona Wilkinson- I don’t think it does, I think it’s just that people are more health aware nowadays, and they have access to more information through the internet.

PatientTalk.Org- What common ways are used by empowered patients to improve their health?

Shona Wilkinson- Yes, I think people are now more aware of their health. They’re more aware of where to find out information. I think also people know that if you cook your food at home you know exactly what’s going into that food. Whereas if you buy a ready meal for example you can probably guarantee it’s got sugar and salt in it to begin with because that’s what our taste buds like. So I think the health empowered patient is knowing that they want to cook their food at home and be a bit more aware of exactly what they’re eating.

PatientTalk.Org- Finally what advice would you give to somebody who has just diagnosed themselves with an allergy or intolerance?

Shona Wilkinson – Yes I wouldn’t like to think that anyone is diagnosing themselves with an allergy that has to be done by a medical professional. If they think they have a food intolerance, try keeping a food diary and making sure that you do. And perhaps speak to a nutritionist to get some advice, the best way to deal with this.

Up to a quarter of us now may suffer from allergies.

Allergy levels are on the rise with an estimated 1 in 4 Brits suffering from an allergy at some point in their lives

Research has identified an increasing trend of people suffering with allergies, with hay fever, skin allergies and rashes the most common problems faced. Experts have seen numbers of allergy sufferers grow in the last two decades, with an annual rise of approximately 5%.

Currently, 20% of children have allergy issues and a child is twice as likely to suffer if their mother is allergic. Dr Pixie McKenna, the UK’s leading female medic, encourages early diagnosis and correct management of the allergy: “When we think about allergies, we often think of the great outdoors and this is undoubtedly where the majority of contact with potential triggers occurs. However, it’s important to consider the impact of indoor allergens like dust mite, pet hair and pollen particles that can find their way indoors. “


“Thankfully, gone are the days when we had to rely solely on elbow grease to tackle allergens in the home; now there are some fantastic products on the market including Hotpoint’s vacuum cleaners, steam mops, washing machines and tumble dryers which carry the UK Allergy seal of approval.”

Providing one explanation for this rapid growth in allergies, Dr Pixie said: “It is well known that early exposure to bacteria and microorganisms in childhood primes our immune system and current thinking holds that our environment has become so sterile that we are missing out on exposure to both bad and good germs. This isn’t of course to say that we should revert back to a world without sanitation, but as researchers, we need to challenge ourselves to understand why early exposure to microbes makes us less likely to be allergic. We need to harness their USP to help us reduce global allergy rates”

Allergens can find their way into the home from outdoors and Brits are making basic mistakes that are increasing their chances of suffering from allergies. Spending a day outdoors causes pollens and other allergens to stick to clothing, so experts suggest putting all clothes into the washing machine as soon as possible to avoid bedding down with pollen. There is no quick fix when it comes to allergies, but a proactive approach to managing an allergy is the best solution.
