In reality, dust allergy is precipitated by dust mites, a kind of microorganisms that thrive in dust. They acquire their food from dead skin cells and absorb water from the environment and thrive. Moist and warm environments are ideal for them to thrive. However, they themselves don t cause allergic symptoms. 

It is the response of the immune system to them that precipitates the symptoms. Once they are inside the human respiratory system, the immune system responds to them in a negative way. This leads to the production of histamines, a kind of protein that abates swelling, cough, mucous production, runny nose, sneezing, etc.

Symptoms of Dust Allergy:

Dust allergies may lead to various symptoms, some of which may be short lived, while others may be chronic. Some of these symptoms may also be life threatening. While in general people may suffer from running nose, stuffy nose, sneezing, coughing, itchy eyes, postnasal drip, swollen skin under the eyes, etc., in severe cases, people may also suffer from asthma, chest pain and tightness, trouble in sleeping due to shortness of breath, bouts of severe cough, sinus infection, etc.

Risk Factors:

Some of the common risk factors are: 

Family History: People who have a family history of dust allergy are most susceptible to this problem. These people develop a sensitivity to dust mites.

Exposure: Exposure to dust mites is the main cause of dust allergy. If someone is exposed to dust mites for a long time, it enhances the risk of allergy symptoms.

Being a Child: Children are more susceptible to it than adults. They are more likely to develop allergies during childhood and early adulthood compared to adults.

Diagnosis:

Most dust allergy symptoms are similar to common cough and cold symptoms. This is why it is necessary to confirm that the symptoms owe their origin to dust allergy. As a primary physical examination, the doctor may examine the lining of nasal passage to see if it is swollen.

In case the person is allergic to dust or pollen, the lining of the nasal passage is likely to become inflamed. However, the doctor also needs to conduct some tests. He may conduct skin tests and blood tests to confirm the allergy. If the allergy is confirmed, the doctor goes for treatment.

Treatment:

There are a number of treatment options for dust allergy. Some of these may act as over-the-counter to counter the effects of dust allergy, while others may act as modulators to modulate the immune response.

Antihistamines: These are medicines that counter histamines responsible for allergic reactions like itching, runny nose, sneezing, etc.

Corticosteroids: Corticosteroids are usually delivered through nasal sprays to bring down inflammation and control the allergic response of the immune system.

Decongestants: They help to decongest nasal airways which get inflamed and swell up due to allergic reactions.

Leukotriene Modifiers: These medicines block certain immune system chemicals responsible for allergic reactions and prevent allergic reactions.

Immunotherapy: The doctor may go for immunotherapy if no other effort is yielding any results. This therapy trains the immune system so that it does not become sensitive to dust mites. It is delivered via injections.

Conclusion:

The primary defense against dust allergy is avoiding breathing in dust. However, if a person is already exposed to them, there are a number of medicines and treatment options to prevent a flare up.

Dust Allergy - Risks, Diagnosis & Treatment Of It!

Every year, the emergency rooms at hospitals get flooded by cases of allergic reactions from food. According to a census, about 15 million Indians suffer from some kind of food allergy. The symptoms of food allergy may vary from itchy mouth to potentially fatal conditions like anaphylactic shock. Other symptoms of an allergic reaction can present themselves as difficulty in breathing, swelling of the tongue, rashes and intestinal discomfort.

According to specialists, allergies to food can develop at any age, at any time. Hence, if you suspect a sudden allergic reaction to a food that you have consumed before without any problem, it is advised to consult your doctor.

Here is a list of the most common food allergies that people suffer from frequently-

MILK: Milk is the most common food that children and infants are allergic to. Milk allergy must not be confused with lactose intolerance wherein a person faces many difficulties in digesting the sugar present in milk. The two conditions are not related. Milk allergy is the hypersensitivity reaction that happens in response to certain proteins present in milk and can be potentially deadly. Most children are seen to outgrow their allergy to milk.
WHEAT: It is a common misconception to confuse Celiac's disease with a wheat allergy. Wheat allergy exclusively occurs due to the hypersensitivity to the protein present in wheat alone. In Celiac's disease, it is the gluten in the food they are hypersensitive to, which is also present in rye, barley and oats.
SOY: Soy is a very common allergic food and most children seem to outgrow it by the age of 10. Most of the time, soy allergy is not too severe and the symptoms presented are mostly mild. Although, cases of anaphylaxis in reaction to soy have been reported. Soy and soy protein are very common ingredients found in food, hence it is advised to check the ingredients present before consuming it.
SHELLFISH: This allergy usually does not go away and you are most likely to deal with all your life. Most people who experience allergies from shellfish are most likely to be hypersensitive to both crustaceans (lobsters, shrimps and crabs) and mollusks (mussels, oysters, scallops and clams). This type of allergy can become very intense and you must even avoid the steam produced from cooking shellfish. For some people, the mere contact with shellfish can trigger an allergic reaction.

4 Most Common Food Allergies

Food allergy is actually an abnormal response triggered by the immune system to food as if it is threatening. Food intolerance looks similar to food allergies. However, the difference lies in how each one of them affects an individual. Food allergy is extremely intrinsic and to an extent, affects the internal organs. 

On the other hand, food intolerance is less severe, mostly just affects the digestive system due to the inability to digest that particular food properly, leading to an upset stomach. Most of the people suffer from food intolerance only, but they confuse it with food allergy.

About ninety percent of all cases of food allergy are related to only eight types of food as per research statistics. These are milk, tree nuts, egg, peanut, soy, wheat, shellfish, and fish.

The Reaction:\

In order to understand how symptoms manifest, it is of utmost importance, in this case, to understand how an allergic reaction to food occurs. An allergic reaction is a bi-step process as discussed further.

Step1: On exposure to the food allergen for the first time, the body reacts abnormally and produces IgE antibodies against the perceived allergen. These circulate throughout the entire body with blood and attach themselves to basophils (found in blood) and mast cells (found in sites like the nose, lungs, throat, gastrointestinal tract, skin, etc.).

Step 2: The next time the body is exposed to a particular food allergen, it gets alert and alarms the tissue that releases histamine in large quantity. Depending on the site of release, allergy symptoms are caused, ranging from mild to severe to potentially life-threatening (for example, in anaphylaxis).

The time span for an allergic reaction manifesting into symptoms can vary between a few minutes to several hours post exposure to the food allergen. The site of mast cells for release of histamine greatly affects the location and timing of the reaction.

Who is at Higher Risk?

If a person has a family history of developing a food allergy, it creates even greater chances for him/ her to have the same or similar reactions. If both the parents have some kind of allergic reaction to food, it is very likely that the child would have that too.

Symptoms:

Symptoms of food allergies largely depend on the sites of mast cells that release histamines. It is possible that these sites are located in nose, ears, or throat leading to itching in mouth, having a trouble in swallowing and breathing, and swelling of lips and tongue. If the location is in the gastrointestinal tract, it may lead to vomiting, diarrhoea, and abdominal pain. If it is in the skin, it might lead to hives, itching, decolourization, pigmentation, worsened eczema, etc.

Cross Reactivity:

If a person has an allergy to a particular food, it is advisable to abstain from similar types of food. For example, if somebody is allergic to crab, he/ she should abstain from shrimp, crayfish, lobster, etc. too as they might also trigger the reaction. This is called cross reactivity.

Treatment:

It is always advisable to abstain from foods which cause an allergic reaction in an individual. However, in case it has already occurred, there are two major types of medication which help in relieving the symptoms. Antihistamines are used for treating mild to chronic reaction, whereas adrenalines are used for severe reaction like in anaphylaxis.

Take Away:

Food allergy is usually a condition for life and cannot be permanently treated. However, symptoms can be relieved. Therefore, it is advisable to avoid the allergy, causing group of food.

Food Allergy - Everything About It!

Food allergies can be defined as a sign of danger given by the human body when it considers some particular food items as harmful. This is basically an allergic reaction to some food proteins. As per the Center for Disease Control and Prevention, about 4 to 6 percent of kids and 4 percent of adults worldwide are affected by different types of food allergies. The most interesting fact about the food allergies is that you can develop an allergy to a particular food at any age. Also, one can develop an allergy to a particular food even when you have been eating that food with ease all these years.

Food allergies can be categorized into main types:

Immunoglobulin E (IgE) mediated allergies: These allergies occur mostly in infants and children and can be seen for milk, peanuts, eggs, soy, and wheat. Moreover, the affected body areas include the mouth, skin, eyes, heart, brain, and gut.
Non-IgE mediated food allergies: These allergies normally affect the digestive tract and symptoms of these food allergies take a long time to develop.
Let us have a detailed look at different methods that can assist you in dealing with different food allergies.
Remove food items that can trigger allergy
It is obvious that food allergy is pertaining to a particular food and thus it is advisable to remove the triggering food items from your diet. It is also advised to remove the byproducts of such food items. This will minimize the danger of food allergy. There are some common food items which can trigger the food allergies which are:

Milk
Eggs
Wheat
Fish
Peanut as well as tree nuts such as walnuts
Shellfish
Soy
Try to stock your pantry with alternatives to the allergic food items. There is no need to make your taste buds suffer by removing food items which can activate allergies. You can try alternatives to such food items and have a healthy life. Read the label on food while shopping for groceries as most of the triggering ingredients are common in many of the food items. Thus, it is advisable to read the ingredients on the food labels before you buy them. You can also look for these common names for allergens:

Glucosamine for Shellfish
Flour, triticale, durum, vital wheat gluten for wheat
Natto, tempeh, shoyu, miso, Edamame, for soy
Roe, surimi, nuoc mam, fish gelatin for fish
Rennet casein, tagatose, whey, rennet casein, casein in milk
Lysozyme, vitelline, surimi, albumin, livetin, globulin, and lysozyme for egg
Write down your meal plans
Preparing your own meal can minimize the risk of food allergies. Thus, try to make your own food and keep a memo of what you would like to eat in a meal. This way you can eliminate the dishes which include triggering ingredients. These above-mentioned methods can surely help you in preventing food allergies effectually. However, if the symptoms of food allergies are severe, do not hesitate to take medical help.

Food Allergies - How To Deal With Them?

Allergies are a reaction of your immune system to any foreign matter, such as pet dander, pollen or bee venom, and not everyone is affected in the same way.
Antibodies are substances produced by your immune system to protect you from harmful invaders that can cause infections or make you ill.
The immune system produces antibodies when it comes into contact with allergens. Your immune system can recognise any allergen as threatening even if it s not. As a result, your skin, airways, digestive system or sinus gets inflamed.
Allergies can vary greatly in severity from mild irritations to anaphylaxis (a likely life-threatening emergency). Allergies are mostly incurable; however, there are various treatments available to alleviate allergy symptoms.
Causes-
Common triggers of allergy include:
Airborne allergens, such as mould, dust mites, animal dander and pollen.
Certain foods, especially milk, eggs, shellfish, fish, soy, wheat, tree nuts and peanuts.
Insect bites, such as wasp stings or bee stings.
Medications, specifically penicillin-based antibiotics or penicillin.
Latex, or any allergen you touch, causes skin infections.
Symptoms-
Symptoms of allergy depend on its type.
Hay fever (allergic rhinitis) symptoms include:
Sneezing
Itching of the roof of the mouth, eyes or nose
Stuffy, runny nose
Swollen, red or watery eyes (conjunctivitis)
Symptoms of food allergy include:
Tingling mouth
Swollen throat, face, tongue or lips
Hives
Anaphylaxis (a critical, deadly allergic reaction)
An allergy caused by insect stings can manifest in symptoms such as:
Swelling at the site of the sting
Hives or itching
Breathing problems, wheezing, coughing or chest tightness
Anaphylaxis
A drug allergy can lead to symptoms such as:
Hives
Itchy skin
Rashes
Facial swelling
Wheezing
Anaphylaxis
Atopic dermatitis (skin allergy) symptoms include:
Itching
Reddened skin
Peeling or flaky skin
Treatment-
Treatments of allergy include:
Avoiding Allergens: Your doctor can help you take necessary steps to recognise and avoid the allergens that trigger allergies. This is usually the most relevant step in the prevention of allergic reactions and reduction of symptoms.
Medicines to Lower Symptoms: Eye drops, nasal sprays or oral medications are commonly prescribed to reduce reactions and alleviate symptoms.
Immunotherapy: If the allergy is severe or other treatments fail to relieve symptoms, allergen immunotherapy is recommended. In this treatment, you get injected by a number of clarified allergen extracts over the years.
Emergency Epinephrine: If your allergy is severe, your doctor will provide you with an emergency epinephrine shot that you can carry with you everywhere. 

Allergies: Causes, Symptoms and Treatments

Your child is fond of nuts and has eaten a chocolate with nuts but shortly after that develops a skin rash and starts to itch. The rash may even spread to the surrounding area. This is an indication of food allergy to nuts.

What happens is simple - the body's immune system recognizes specific proteins in the food as harmful (antigens) and produces antibodies which can combat them. This leads to an allergic reaction which can vary from something as simple as a skin rash to severe breathing issues.
Though any child can develop food allergies, in most cases, there is a strong hereditary linkage. If parents have had a history of allergy to certain foods, then there is a strong likelihood that the child could have that food allergy too.

Some of the common foods that can cause allergies are as follows:
1. Cow's milk
2. Eggs
3. Nuts (peanuts, walnuts, pecans, cashews or hazelnuts)
4. Soy
5. Wheat
6. Fish (salmon, cod and others)
7. Shellfish (lobsters, shrimps and others)
Of these, peanuts, seafood, and milk are the most common food stuffs that lead to allergies.

Because the child is yet to realize that he has eaten something that his system will not readily accept, the allergic reaction can be described in various ways, as below:
1. Scratching or itching on the tongue
2. Change in the voice - can become husky or hoarse
3. Burning of the tongue
4 tingling of the tongue
5. Funny feeling in the mouth
6. Feeling of something stuck in the throat
7. Itchy feeling or bugs in the ears
8. Throat going thick
9. Bump on the back of the tongue

These are some ways that a child can describe his allergic reaction. Some of the mild symptoms of a food allergy are as follows:
1. Hives (red, swollen, itchy areas on the skin)
2. Eczema of the skin (dry, itchy rash)
3. Nasal congestion
4. Sneezing
5. Itching of the tongue and the mouth
6. Nausea or vomiting
7. Stomach pain

Severe symptoms include:
1. Severe swelling of the lips and tongue that can block breathing
2. Inability to swallow
3. Difficulty breathing
4. Turning blue
5. Dropping of pulse
6. Drowsiness

As the parent identifies a similar reaction when eating the same food item, they can suspect allergic reactions and immediately reach out to the doctor. A detailed discussion will help establish the causative agent. Once that is known, then avoiding food allergies is quite easy. In fact, a well-informed child will know that avoiding certain foods is very beneficial. This will improve the quality of life of the child, help avoid missing school due to allergic reactions, and help avoid the child (and the parent) suffering.
