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!

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.

How to Know if Your Child Suffers From Food Allergy

Breathing is inhalation and exhalation, where oxygen is inhaled into and carbon dioxide is released from the body. Air passes through the nose, which has fine hair and mucus to filter out suspended particles in the air like pollen. When the person s immunity is weakened or is highly reactive, the mucosa reacts to many substances which are generally present. This is known as allergic rhinitis.

Types: Depending on the occurrence, it can be:

Seasonal: For instance, in spring when there is too much pollen in the air; known as hay fever. This is an acute rhinitis and subsides with a change in weather.
Chronic: This is when the body reacts to some normal substances like eggs, animal dander, extreme cold, dust, mites, etc. via an allergic reaction.
Causes of allergic rhinitis as per Ayurveda

Mandagni   low digestion strength
Kapha vruddhi   increase of Kapha dosha
Allergens   external factors such as pollen, dust etc
Residing with pet animals
Exposure to humidity, dust, cold
Virudh aahara   wrong food combinations
Long term intake of drugs like aspirin, leading to depleted immunity and making the person prone to dust allergies.
Symptoms:

Runny nose for prolonged periods of time
Chronic congestion
Persistent sneezing
Teary eyes
Fever and headache
Ayurveda believes that this is due to excessive kapha dosha. So, in order to manage allergic rhinitis, two approaches should be taken. Foods which increase kapha should be avoided, and elimination of kapha from the body should be targeted.

Non-medical ways to combat allergic rhinitis: 

Prevention has a big role to play in managing allergic rhinitis.

Whether it is animal dander, eggs, tomatoes, or extreme cold, if you know it could cause an attack, stay away from it.
Chew foods properly to ensure through absorption of vitamins and minerals, which are essential for immunity
Boil water with a spoonful of turmeric and a pinch of salt and drink it regularly
Basil and mint leaves can be boiled in water and consumed for improving allergic rhinitis
Clove and pepper can be chewed to get immediate relief
A mixture of crushed clove and pepper mixed with turmeric and honey works wonders for allergic rhinitis
Eat seasonal fruits and vegetables. They are more likely to be chemical-free, are cheaper, fresher, and definitely more nutritious.
Carrots eaten with a bit of fat produce the best defense against allergic rhinitis, as the beta-carotene in it is fat soluble.
Whole grains, green leafy vegetables, seasonal fruits and vegetables, and dairy products, contain a number of vitamins and minerals which help in fighting allergic rhinitis
Ayurvedic remedies like shilajit and guduchi boost immunity function
Neem, Ashwagandha, liquorice, cinnamon, tulsi, and curcumin are proven remedies for allergic rhinitis.
Panchakarma specifically aimed at rhinitis include Nasya, Dhoomapana (medicated smoking) and emesis (vaman ). This helps in eliminating kapha which is believed to cause allergic rhinitis.
Though allergic rhinitis is a very common condition, the treatment is also easy and many home remedies help in managing the condition.

Lifestyle improvement:

Always keep cloves and black peppers with you. Immediately keep two pieces of it in mouth when you feel of attack.
At the pre attack or attack rub Nilgiri oil , Mint oil, or pain balm on chest and get fomentation.
Keep watch on the elements that causes irritation for you and stay away from this.
Use mask while driving vehicle or going through public places.
Always take warm water bath.
Do not expose to hot sunrays.
Regularly take inhalation of steam.
Regularly go for morning walk in warm weather.
Do sufficient exercise.
Do not reside in dark or dump places. Get fresh air.
Do not get sleep at day time or immediate after dinner.
Take sufficient rest.

Diet, Nutrition & Ayurveda Treatment For Allergic Rhinitis!

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!

Allergies are caused by unnatural reactions between your body's immune system and foreign substances, which have gained access into the body. When these substances, known as allergens, enter your body, your immune system produces antibodies, which are responsible for warding off unwanted substances like harmful viruses or diseases and helping in the body's overall resistance.

The main cause of allergy is the uncontrolled reaction between the immune system's antibodies and harmless allergens. Allergic reactions are triggered when antibodies, like histamine, come into contact with particular types of allergens. These may include:

    Certain eatables: Peanuts or sea food
    Medications: Penicillin or penicillin-based antibiotics
    Airborne allergens: Pollen, mold, or dust mites
    Insect stings: Bee stings or scorpion stings
    Latex: Latex or other substances, which are responsible for causing allergic skin reactions

Symptoms of allergies depend upon a wide range of factors, which are subjective and vary from person to person and from allergen to allergen. Depending upon the type of allergen involved and the nature of the allergy, symptoms may include any of the following:

    Facial swelling
    Wheezing
    Severe itching
    Swollen or red and watery eyes
    Hives
    Flaky skin which can peel off

These symptoms are common in mild to moderate allergies, such as atopic dermatitis, hay fever, drug or food allergies. There are certain rare cases (say, scorpion stings), however, in which the allergic reaction turns out to be potentially life-threatening. This type of reaction is known as anaphylaxis. Here are its signs and symptoms:

    Nausea and vomiting
    Loss of consciousness
    Skin rashes
    Intense shortness of breath
    Lightheadedness

Homeopathy effectively deals with any sort of allergy by taking into account individualistic symptoms and thus nipping the root cause in the bud. Natrum Mur, Urtica Urens, Sulphur and Natrum Carb, among others, are very effective medicines against allergies. But these must be taken after due discussion with the doctor as they check out the symptoms and then prescribe the medicine basis that.
