With a food allergy, there is an Fkod reaction of the body's immune system to a particular type of food. People with certain symptoms might need to be tested for celiac disease, but few people with gluten intolerance have celiac disease. In some instances, babies will develop bloody diarrhea. Formal double-blinded, placebo-controlled food challenge tests are the ideal test for diagnosis but are logistically difficult and expensive so not done very often in practice.

Food allergy and intolerance management -

Around two in children and one in adults have a nut allergy in the UK. Nuts are a staple These are all possible symptoms of a food allergy. They range from the mild reactions and chronic symptoms to the most severe and life-threatening ones.

Some of these symptoms are the same as those which can be caused by a non-IgE food allergy. So this shows how complicated it can be to determine whether you have an allergy or an intolerance.

An allergy is a response by the body's immune system to something called an allergen that is not necessarily harmful in itself. Certain people are sensitive to this allergen and have a reaction when exposed to it.

Some allergic reactions are mild and harmless, but others are severe and potentially life-threatening anaphylaxis. See the separate leaflets called Allergies and Anaphylaxis for more information. There are different types of food allergy, depending on which part of the immune system responds.

The acute, sudden-onset reactions tend to be caused by antibodies called immunoglobulin E IgE. These are called IgE-mediated reactions. As a result of these reactions, various chemicals are made, including histamine.

Histamine causes many of the allergy symptoms and this is why antihistamines can be used to treat some allergic reactions. There are also non-IgE-mediated reactions which tend to be more delayed and less severe. In these reactions the symptoms are not caused by IgE.

Instead other parts of the immune system, such as a type of white blood cell, called a T cell, cause the problem. Common reactions include skin problems such as rashes and eczema, and tummy abdominal symptoms and bowel disturbance.

This causes diarrhoea and tummy abdominal symptoms bloating and pain after milk is drunk or dairy products are eaten. It happens because of a deficiency of lactase, an enzyme in the body that digests the sugar in milk lactose.

Unless lactose is broken down, the body cannot absorb it. You can be born without any lactase, or only a low level, or you can develop lactase deficiency - often after an episode of infection of the gut gastroenteritis.

See the separate leaflet called Lactose Intolerance for more details. Certain foods and chemicals in foods may directly affect the body and cause symptoms.

For example, some people find that the food additive monosodium glutamate MSG causes flushing, headache, abdominal pains and bloating. However, the exact way in which foods and additives may cause symptoms is often not clear.

There is controversy about whether certain food additives E numbers are responsible for various symptoms, especially in children. Also, there is uncertainty as to whether certain foods can make symptoms worse in some people who have conditions such as irritable bowel syndrome IBS , migraine and eczema.

Some people, especially children, may develop physical symptoms such as feeling sick and diarrhoea if they eat, or are offered, foods they have come to dislike.

Strictly speaking this is not a true food intolerance. It may, however, be difficult to distinguish between avoidance and intolerance in children.

Also, many people incorrectly assume symptoms they have are due to food intolerances when in fact their symptoms are not due to food.

Consequently, people commonly cut things out of their diet that they believe to be the cause of their problems. In itself this can lead to further problems. In summary, food intolerance often ends up being a rather vague term which is sometimes difficult to clarify.

Some people get a type of allergic reaction to certain foods that only causes symptoms in the mouth and throat. It tends to cause itching, tingling, and swelling of the mouth, lips and throat.

Fresh fruit, vegetables and nuts commonly cause this. It can be confused with an extreme form of allergic reaction anaphylaxis. It has the potential to be serious, as swelling in the mouth and throat can affect the ability to breathe; however, this is rare.

The symptoms start within minutes of eating and tend to settle completely within an hour. Often if you have this condition, you can eat cooked versions of these foods with no problem, but the raw food gives you symptoms.

This is because the proteins causing the allergic reaction are destroyed by the cooking process. Oral allergy syndrome usually affects people who get hay fever , and may also be called pollen food syndrome. Note : an ambulance should be called immediately if you feel faint, have difficulty breathing or feel like your throat is closing up.

It is very difficult to know how common true food allergy really is. Studies tend to come up with very different figures. depending on how they are set up. They suggest that in the developed world anywhere between 1 and 17 people out of have a food allergy.

People tend to report food allergy more often than it is confirmed by formal testing. Many people mistakenly believe they have food allergies. Also, children can 'grow out' of allergies - for example, to cow's milk.

The number of people with food allergies seems to be rising. However, the severity of these allergies varies. If you think you have, or your child has, a food allergy, you should seek medical advice. Usually your GP would be the first port of call.

You may be referred to a consultant in hospital often an immunologist or an allergist. This would be for further tests to confirm the diagnosis. This would often happen if a severe allergic reaction or anaphylaxis has occurred, or if a child is not growing well and has gastrointestinal symptoms such as diarrhoea.

If you think you or your child have a food intolerance, it depends on the severity of symptoms as to how promptly you seek medical advice.

In milder, less clear-cut situations, it is often worth spending some time yourself trying to work out which foodstuff is the culprit. Keeping a diary of what is eaten is a simple activity that can be helpful in some cases.

You need to write down everything that is eaten and any reaction that you have. A food diary does not provide a diagnosis but it does suggest which type of food s could be the culprit s , allowing further tests.

If it is thought that you have an IgE-mediated allergy, there are two main types of test that can be done:. This is usually done in a specialist hospital allergy clinic. Because an anaphylactic reaction is possible, there needs to be access to resuscitation equipment including adrenaline epinephrine.

A small drop of liquid containing the food substance is placed on to the skin of the forearm and a needle is used to prick the skin, through the droplet.

This allows the food to enter the skin. After a period of time, the droplet is wiped off and the skin is looked at to see if there has been a reaction, and how big this is.

Usually there would be an itchy red area with a surrounding white raised swelling called a wheal. See the separate leaflet called Skin Prick Allergy Test for more details. Blood tests can detect if your blood contains specific IgE antibodies.

You can set up household rules to prevent cross-contamination when storing, preparing and serving food. You have more time to read food labels and, for parents of children with food allergy, teach your child this skill in a relaxed setting. Always have an Anaphylaxis Emergency Plan and an auto-injector at home.

Ideally you should keep at least two auto-injectors on hand, in case you need a second dose during an allergic reaction. Download an Anaphylaxis Emergency Plan. Remember The kitchen refrigerator is a great place to post a copy of your emergency plan.

Symptoms of allergic reactions to foods are generally seen on the skin hives, itchiness, swelling of the skin. Gastrointestinal symptoms may include vomiting and diarrhea. Anaphylaxis pronounced an-a-fi-LAK-sis is a serious allergic reaction that happens very quickly.

Symptoms of anaphylaxis may include difficulty breathing, dizziness or loss of consciousness. Without immediate treatment—an injection of epinephrine adrenalin and expert care—anaphylaxis can be fatal.
