Whats a malt allergy
Imagine being allergic to a substance that makes up about 70 percent of the ground and almost as much of our bodies. But for some, a rare allergy to water is harsh reality.
Michaela Dutton, 21, has aquagenic urticaria, which causes her to get hives when her skin comes in contact with water. While physical urticarias are not unusual — people can develop hives within minutes in response to ordinary stimuli including heat, freezing and pressure — sensitivity to water is far less common.
Dutton said she broke out in a red rash and white blisters after she took a bath about a week after her son was born three years ago. Although she ignored the reactions at first, her symptoms worsened and she went to see a doctor and a dermatologist who told her she had a water allergy.
«It’s horrible,» Dutton said. «I couldn’t believe it at first,» Dutton said.
«Water induced urticaria is extremely unusual — there are not numerous cases ever reported,» said Dr. Thomas Casale, chief of allergy and immunology at Creighton University and executive vice president of the American Academy of Allergy, Asthma & Immunology.
«The mechanism has not really been defined.»
It is certain, however, that people with aquagenic urticaria produce histamine from mast cells in the skin which causes redness, rashes and hives if they touch water. Dutton’s sensitivity is such that she can only bathe for about 10 seconds each week and cannot drink water, juice, tea or coffee, opting for diet cola instead. She is also restricted from eating certain fruits and vegetables.
«It’s not a problem with water in the body. It’s when [water] is applied on top of the body,» Casale said, citing additives as a possible cause for the allergic reaction seen on the skin.
Dutton, who lives in Walsall in the UK, also must be careful when holding her 3-year-old son. Her allergy was triggered after his birth and even his tears can cause hives.
«He doesn’t really understand,» Dutton said. «If he falls asleep I own to watch he doesn’t dribble on me.»
Physical urticarias tend to happen in individuals starting in their 20s and 30s but it is impossible to predict how endless the condition will final.
«Some of these can be time limited but some can final for fairly a few years,» Casale said.
Most urticarias are treated with antihistamines but Casale said that because they are so rare, there own been no major breakthroughs in treatments.
How to manage an allergy
In many cases, the most effective way of managing an allergy is to avoid the allergen that causes the reaction whenever possible.
For example, if you own a food allergy, you should check a food’s ingredients list for allergens before eating it.
There are also several medicines available to help control symptoms of allergic reactions, including:
- lotions and creams, such as moisturising creams (emollients) – these can reduce skin redness and itchiness
- decongestants – tablets, capsules, nasal sprays or liquids that can be used as a short-term treatment for a blocked nose
- antihistamines – these can be taken when you notice the symptoms of a reaction, or before being exposed to an allergen, to stop a reaction occurring
- steroid medicines – sprays, drops, creams, inhalers and tablets that can assist reduce redness and swelling caused by an allergic reaction
For some people with extremely severe allergies, a treatment called immunotherapy may be recommended.
This involves being exposed to the allergen in a controlled way over a number of years so your body gets used to it and does not react to it so severely.
Is it an allergy, sensitivity or intolerance?
What’s the Difference Between Wheat Allergy and Celiac Disease?
An allergy to wheat involves an allergic response to a protein in wheat. Gluten is not one of the wheat proteins that typically causes an allergic reaction. Gluten is involved in a condition called celiac disease.
It’s simple to confuse celiac disease with wheat allergy, but they are extremely diverse.
Celiac disease does not cause an allergic reaction. With celiac disease, there is a diverse type of immune system response in the intestines, causing a problem with the absorption of food.
While people with wheat allergy can generally eat other grains, people with celiac disease cannot eat any food containing gluten, which is also found in other grains such as barley, rye, and sometimes oats.
What Are the Signs & Symptoms of a Wheat Allergy?
When someone with a wheat allergy has something with wheat in it, the body releases chemicals love .
This can cause symptoms such as:
- red spots
- throat tightness
- itchy, watery, or swollen eyes
- trouble breathing
- belly pain
- a drop in blood pressure, causing lightheadedness or loss of consciousness (passing out)
Allergic reactions to wheat can differ. Sometimes the same person can react differently at diverse times. Some reactions can be extremely mild and involve only one system of the body, love hives on the skin.
Other reactions can be more severe and involve more than one part of the body.
Wheat allergy can cause a severe allergic reaction calledanaphylaxis. Anaphylaxis might start with some of the same symptoms as a less severe reaction, but can quickly get worse. The person may own trouble breathing or pass out. More than one part of the body might be involved. If it isn’t treated, anaphylaxis can be life-threatening.
How Is an Allergic Reaction to Wheat Treated?
If your kid has a wheat allergy (or any helpful of serious food allergy), the doctor will desire him or her to carry an epinephrine auto-injector in case of an emergency.
An epinephrine auto-injector is a prescription medicine that comes in a little, easy-to-carry container.
It’s simple to use. Your doctor will show you how. Kids who are ancient enough can be taught how to give themselves the injection. If they carry the epinephrine, it should be nearby, not left in a locker or in the nurse’s office.
Wherever your kid is, adult caregivers should always know where the epinephrine is, own simple access to it, and know how to give the shot. Staff at your child’s school should know about the allergy and own an action plan in put. Your child’s save medications (such as epinephrine) should be accessible at every times.
Every second counts in an allergic reaction. If your kid starts having serious allergic symptoms, love swelling of the mouth or throat or difficulty breathing, give the epinephrine auto-injector correct away.
Also give it correct away if the symptoms involve two diverse parts of the body, love hives with vomiting. Then call and take your kid to the emergency room. Your kid needs to be under medical supervision because even if the worst seems to own passed, a second wave of serious symptoms can happen.
It’s also a excellent thought to carry an over-the-counter (OTC) antihistamine for your kid as this can assist treat mild allergy symptoms.
Use after — not as a replacement for — the epinephrine shot during life-threatening reactions.
The exaggeration of the normal effects of a substance. For example, the caffeine in a cup of coffee may cause extreme symptoms, such as palpitations and trembling.
What Is a Wheat Allergy?
When someone is allergic to wheat, the body’s immune system, which normally fights infections, overreacts to proteins in the wheat. If the person eats something made with wheat, the body thinks these proteins are harmful invaders and responds by working extremely hard to fight off the invader.
This causes an allergic reaction.
Wheat allergy is more common in kids than adults, and numerous children seem to "outgrow" their wheat allergy over time.
Where a substance causes unpleasant symptoms, such as diarrhoea, but does not involve the immune system.
People with an intolerance to certain foods can typically eat a little quantity without having any problems.

What Else Should I Know?
If allergy testing shows that your kid has a wheat allergy, the doctor will give you guidelines on keeping your kid safe.
Your kid must completely avoid products made with wheat. Although most allergic reactions to wheat happen after eating a wheat product, sometimes people can react to raw wheat that they breathe in (such as a baker who inhales flour in the workplace).
Natural food stores and the health food section in grocery stores generally own safe alternatives, including wheat-free breads, crackers, and breakfast cereals.
Also, glance for substitute flours made from potato, rice, wheat, barley, oats, and corn. For information on foods to avoid, check sites such as the Food Allergy Research and Education network (FARE).
Always read food labels to see if a food contains wheat. Manufacturers of foods sold in the United States must state whether foods contain any of the top eight most common allergens, including wheat. The label should list "wheat" in the ingredient list or tell "Contains wheat" after the list.
Some foods glance OK from the ingredient list, but while being made they can come in contact with wheat.
This is called cross-contamination. Glance for advisory statements such as "May contain wheat," "Processed in a facility that also processes wheat," or "Manufactured on equipment also used for wheat." Not every companies label for cross-contamination, so if in doubt, call or email the company to be sure.
Cross-contamination can happen if wheat gets into a food product because it is made or served in a put that uses wheat in other foods.
This can happen on kitchen surfaces and utensils — everything from knives and cutting boards to a toaster or grill. Fried foods often own the potential to be cross-contaminated, because they can be fried in the same oil as foods that contain wheat.
When eating away from home, make certain you own an epinephrine auto-injector with you and that it hasn’t expired. Also, tell the people preparing or serving your child’s food about the wheat allergy.
Sometimes, you may desire to bring food with you that you know is safe. Don’t eat at the restaurant if the chef, manager, or owner seems uncomfortable with your request for a safe meal.
Also talk to the staff at school about cross-contamination risks for foods in the cafeteria. It may be best to pack lunches at home so you can control what’s in them.
Other things to hold in mind:
- Don’t feed your kid cooked foods you didn’t make yourself or anything with unknown ingredients.
- Make certain the epinephrine auto-injector is always on hand and that it is not expired.
- Tell everyone who handles the food — from relatives to restaurant staff — that your kid has a wheat allergy.
March 3, — In the world of allergies, there are a few common culprits to which numerous sufferers can relate.
Pollen, peanuts and even egg and wheat are some that are widely known and, hence, widely understood.
They’re annoying for certain, but at least their victims can take solace in the fact that they are not alone in their distress.
But what of those whose allergies drop exterior of the mainstream.
For example, those allergic to meat?
«We’ve been looking into this for a couple of years, but it was really unclear how widespread it was,» said Dr. Scott Commins, an allergist and immunologist at the University of Virginia. On Sunday, Commins presented the findings of his latest research on meat allergies before those gathered at the annual meeting of the American Academy of Allergy Asthma and Immunology (AAAAI) in New Orleans.
What Commins and his colleagues found in their preliminary study of 60 patients was that some people may own an allergy to a carbohydrate naturally found within meat. He said that while allergies to certain proteins in meat has been documented before, such cases are extremely rare. But the thought that there is another component of meat that can spur allergies means that the pool of people within the population who own a meat allergy may be more than previously suspected.
It gets stranger. Commins said the patients with this allergy that he studied experienced a peculiar delay in symptoms.
«Initially they will experience nothing,» he said. «About three to four hours in, they’ll start experiencing some itching, which often proceeds to hives.»
Commins said that in some patients the reaction can get even worse, progressing to breathing difficulties, acute onset diarrhea and cramping.
While more details on this allergy will only come with additional research, Commins said the preliminary results propose that people with certain blood types — specifically B and AB — may be less likely to own this type of allergy than those with other blood types.
He also said the research shows that those who own been bitten by ticks or certain other blood-sucking insects may be more likely to own this allergy.
«What is it about tick or chigger bites that causes the production of this antibody?» he said. «We don’t ponder it is something infectious, as with Lyme disease and other conditions, but we are certainly keeping an open mind.»
Dr. Clifford Bassett, assistant clinical professor of medicine and otolaryngology at The Endless Island College Hospital, SUNY-HSCB, in Brooklyn, N.Y., who was not involved with the research, called the study «thought-provoking,» particularly in patients whose allergies own no conventional explanation, a condition shelved under the description «idiopathic anaphylaxis.»
«This condition, idiopathic anaphylaxis, often goes with no concrete cause for it,» he said.
«We should consider this [research] in evaluating this condition.»
Under, we explore 11 other unusual allergies with which a few must contend — in some cases on a daily basis.
Substances that cause allergic reactions are called allergens.
The more common allergens include:
- latex – used to make some gloves and condoms
- medicines – including ibuprofen, aspirin and certain antibiotics
- mould – these can release little particles into the air that you can breathe in
- animal dander, tiny flakes of skin or hair
- insect bites and stings
- dust mites
- grass and tree pollen – an allergy to these is known as hay fever (allergic rhinitis)
- food – particularly nuts, fruit, shellfish, eggs and cows’ milk
- household chemicals – including those in detergents and hair dyes
Most of these allergens are generally harmless to people who are not allergic to them.
Symptoms of an allergic reaction
Allergic reactions generally happen quickly within a few minutes of exposure to an allergen.
They can cause:
- wheezing and coughing
- a red, itchy rash
- red, itchy, watery eyes
- a runny or blocked nose
- worsening of asthma or eczema symptoms
Most allergic reactions are mild, but occasionally a severe reaction called anaphylaxis or anaphylactic shock can happen.
This is a medical emergency and needs urgent treatment.
Getting assist for allergies
See a GP if you ponder you or your kid might own had an allergic reaction to something.
The symptoms of an allergic reaction can also be caused by other conditions.
A GP can assist determine whether it’s likely you own an allergy.
If they ponder you might own a mild allergy, they can offer advice and treatment to assist manage the condition.
If your allergy is particularly severe or it’s not clear what you’re allergic to, they may refer you to an allergy specialist for testing and advice about treatment.

What causes allergies?
Allergies occur when the body’s immune system reacts to a specific substance as though it’s harmful.
It’s not clear why this happens, but most people affected own a family history of allergies or own closely related conditions, such as asthma or eczema.
The number of people with allergies is increasing every year.
The reasons for this are not understood, but 1 of the main theories is it’s the result of living in a cleaner, germ-free environment, which reduces the number of germs our immune system has to deal with.
It’s thought this may cause it to overreact when it comes into contact with harmless substances.
