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!

An estimated 10 to 30 percent of people across the world suffer from Allergic rhinitis. Allergic rhinitis, more commonly known as hay fever, is a condition wherein the immune system overly responds to allergens resulting in inflammation in the nose. As you might be aware, an allergen is typically a harmless substance present in the surroundings causing an uncomfortable allergic reaction.

Following is a detailed account of the condition.

Symptoms-
Some of the most common symptoms of allergic rhinitis include,

Sneezing
Stuffy and runny nose
Persistent coughing
Itchy and watery eyes
Sore throat
Frequent headaches
Dark circles under the eyes
And, symptoms associated with eczema
Further, it also results in hives and excessive fatigue. An allergic person is likely to feel many of these symptoms within a few minutes of coming into contact with an allergen. Some symptoms, such as recurrent fatigue and headaches can only happen when there is long-term exposure to allergens. There are some people, who rarely undergo any signs, and this happens when a person is exposed to the allergens in massive quantities.

Causes of Allergic Rhinitis:
When the body comes in contact with the allergen, it triggers the release of histamine which is a natural chemical that defends the body from the allergen. This histamine can lead to allergic rhinitis and the associated symptoms which may range from a blocked or a runny nose to itchy eyes. Common allergens include pollen, dust mites, animal dander, grass pollen, and mold.

There are two variants of allergic rhinitis- seasonal and perennial.

Seasonal- Seasonal allergies usually occur during specific seasons owing to the response to outdoor allergens. For example, during a specific time in the year such as spring, the pollen can cause allergies in a person. Also, when trees and flowers release pollens during the fall and summer, seasonal allergic rhinitis can be seen on the rise.
Perennial- On the other hand, perennial allergens tend to linger all-round the year, and pet dander, mold or dust mites come under perennial allergic rhinitis causing allergens.
Diagnosing and treating allergic rhinitis-
When a person is suffering from minor allergies, a physical exam may be required. But a doctor may also perform some tests for identifying the best course of treatment as well as prevention plan for a particular patient. A skin prick test is one of the best ways to determine whether you have allergic rhinitis.

This health issue can be treated in a variety of ways which range from home remedies to medications to alternative therapies. Common medications include antihistamines, decongestants and nasal sprays and eye drops.

Staying away from a known allergen is the best possible way to prevent allergic rhinitis. When diagnosed, it is necessary to consult your doctor as the condition may sometimes lead to complications.

Allergic Rhinitis - Everything That You Ought To Know

What is allergic rhinitis?

Allergic rhinitis is defined as allergic symptoms in the nasal passage. Allergic rhinitis can be seasonal (occurring during specific seasons) or perennial (occurring year round). The allergens that most commonly cause seasonal allergic rhinitis include pollens from trees,grasses and weeds, as well as spores from fungi and moulds. The allergens that most commonly cause perennial allergic rhinitis are house dust mites, cockroaches,animal dander,and fungi or moulds. Perennial allergic rhinitis tends to be more difficult to treat.

How does allergic rhinitis occur ?

This condition occurs when allergens (allergy- causing substances) come into contact with the nose, and usually also the ears, sinuses, and the throat. When allergens come in contact with the lining of the nose and sinuses, they trigger the cells to release the chemical histamine, which causes the allergy symptoms described below.

What are the symptoms ?

Nasal congestion 
Sneezing 
Watery " runny nose" 
Itchy eyes,nose,or throat 
Puffy eyes or 'allergic shiners'
Post nasal drip 
Tears 
These symptoms may occur during a certain season or year long. They can occur at any age. 

What is the treatment for allergic rhinitis ? 

A number of medications ,including antihistamines, intranasal corticosteroids, and decongestants are available to control symptoms. Allergen immunotherapy could provide long lasting benefit. You can "train" your immune system not to react exaggerated to an allergen anymore.

Allergic Rhinitis - Signs That You are Suffering from 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.

Food Allergies - How To Deal With Them?

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.

Allergies: Causes, Symptoms and How Homeopathy Deals With It Efectively

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.
