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!

The onset of winter brings with it chilly and dry winds. For some, it s the time to enjoy the chill weather with hot water baths and soothing drinks, and for others it s time to brave the long persistent cold and flu like symptoms which cause sickness and discomfort.

People who are allergic to the winter season can catch a cold on the slightest exposure to cold air. Sometimes, it s difficult to ascertain whether it is cold or an external allergen. In people prone to winter allergies, the allergies are mainly caused due to the allergens present in the environment. Mostly, winter allergies are also caused by the same allergens that are triggered in the summer season. 

Thus, people who have some or the other form of seasonal allergy is likely to suffer from allergies as the season changes.

Pet dander (flakes of skin in an animal's fur or hair) allergies are believed to escalate in winter since pets are mostly indoors during this season. The best way to deal with this is keeping the pet s area clean and dry, washing and changing of the bedding regularly, and avoiding physical contact as much as possible.
Dampness of clothes, blankets and shoes at home can be an allergy trigger for many people. The best way to control this type of allergy is to keep damp clothes and shoes in sun for some time. However, this may not work in many countries with extreme cold climates, which lack sunshine in their environment.
Decaying leaves and other yard waste can cause allergies due to mould and mildew. Mopping and sweeping the floors and garden can help alleviate the problem to some extent.
Dry climate can cause irritation in the nose and throat. It s important to replenish the body with adequate liquids and water rich fruits and veggies. It s important to choose your drinks wisely. Too much tea or coffee can also dehydrate the body. Go for ginger lemon honey infused in warm water for best results.
Allergy symptoms can also be caused due to too much moisture in the environment. It can give rise to a stuffy or runny nose, sneezing and coughing. Thus it s best to avoid sitting in a moist environment for long.
Sinus congestions are also common during the winter season. Steam inhalation and hot showers can help relieve the symptoms and provide relief.
Whether you are allergic to pets, moisture, dampness, dry weather or chilled winds, the thumb rule is twofold to understand what triggers your allergies and to avoid your exposure to those allergens. As we all know, allergies have no cure and they need to be managed. Drugs also help in controlling the allergy symptoms to some extent. However, it s best to prevent them as far as possible. If you are confused about what triggers your allergy, make sure to consult your doctor.

What is Allergic Asthma?

Allergic asthma is the condition in which the symptoms of an asthmatic attack appear after exposure to certain allergens. 90% of the cases of asthma in children are allergy driven, while in adults, the percentage is said to be around 50%.

An allergy happens when an individual's immune system exhibits massive reaction or fights vigorously against substances like pollen, dust, animal dander or certain other minute particles which are actually not harmful to the body but are considered so by the immune system.

Symptomatic changes in cases of allergic asthma:

If the symptoms of an asthma attack occur only when you are subjected to these triggers or irritant particles, your case is allergy driven.

In such cases, the airway reacts aggressively to the entry of such allergens.

The airway muscles tighten up and inflammation is observed.

Breathing becomes painful and compromised, and mucus accumulation sets in very quickly.

Coughing is a common phenomenon, as the body tries to expel the mucus accumulated.

The allergens mentioned above are not the only triggering agents. Basically, anything that causes irritation could trigger an allergy and an asthmatic attack thereafter. Symptoms in the case of allergy driven asthma are more or less the same as seen in other asthmatic cases.

Confirming the cause of asthma as allergic or not:

The doctor would give you a much better clarification on whether you're asthma is allergy driven or not. There are pretty much two ways to decipher the same:

One is to administer a tiny amount of allergen to the skin and making a note of the reaction to that. Whether the reaction is a normal one or an aggressive one would tell if an individual has an allergy or not.

Specific IgE test may be done to confirm the cause, or to test the presence of an allergic reaction in the individual.

All your queries pertaining to allergic asthma and asthma, in general, are more than welcome.

What is Allergic Asthma?

Seasonal allergies are usually characterized by sneezing, coughing and other allergic reactions. Also known as hay fever and allergic rhinitis, the condition tends to appear only during certain seasons of the year. The disease is triggered by changes in the weather and exposure to certain allergens like dust. The allergens cause the body to release histamine into the blood thus, resulting in symptoms of allergy.

The symptoms of seasonal allergy are:

    Coughing
    Sneezing
    Congestion in the nose
    You may experience a blocked and runny nose
    You may have an itchy nose

Ayurveda is a holistic method of treatment that focuses on improving your overall well-being. The various Ayurvedic remedies for treating seasonal allergies are:

    Restrict Dairy Intake: You need to cut dairy out of your diet as dairy products have all the characteristics of a cold food. They tend to create imbalance in the  kapha  dosha in the body, thus leading to various diseases.
    Ayurvedic Detox: Consider doing an Ayurvedic detoxification to cleanse the body of the various toxins. It helps in smoothing out the  dosha  balance and hence improves your overall well-being.
    Nasya: This process requires you to put drops of medicated oils inside your nostrils. This lubricates the nasal cavity and prevents the allergens from causing an allergic reaction in the body.
    Eat More Warm Foods: Try to eat warm and cooked foods as much as possible. Eating frozen foods is not recommended as the nutrients from the food may not be absorbed properly owing to a weak digestive system which may be the result of a bout of severe seasonal allergies. Include foods such as soups and porridge and you have a perfect dish to gorge on.
    Exercise on a Regular Basis: Make sure you exercise on a regular basis to improve your fitness levels and also to keep a check on your weight. Certain  yoga  poses such as the downward dog and the cobra help to improve the digestive process. Add cardio workouts such as running and swimming to improve the health of the lungs.
    Add Spices: Add spices to your cooking such as turmeric or garlic as they help in rejuvenating the respiratory system.

Seasonal Allergies - 6 Natural Remedies That Help you Manage 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

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.
