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!

A rash on your child s body or their regular cough bouts can sometimes be triggered by an allergy.

Symptoms of common allergies

Nasal Congestion: It is referred to as stuffy nose, which is very common in kids. Allergies are the most common cause of chronic nasal congestion (a stuffy nose) in children. Sometimes a child s nose is congested to the point that he or she breathes through the mouth, especially while sleeping.
Allergic rhinitis (hay fever): It is also common and its symptoms include a runny or itchy nose and constant sneezing. A child with allergies may also have itchy, watery, red eyes and chronic ear problems. Even though it s commonly known as  hay fever,  allergic rhinitis isn t triggered by hay and doesn t cause fever.
If you suspect your child has an allergy, make an appointment to see a specialist. Start a diary before the appointment and keep track of what symptoms your child experiences and what you think causes them.

Diagnose of House Dust Mite Allergy:

To diagnose this type of allergy, doctors check the patient physically and if the patient has problems persistently round the year, then he/she may be advised to take an allergy test. Allergy tests consist of skin prick tests and blood tests.

Skin Prick Test: Skin Prick Test, or SPT, is not a conclusive test for every patient. The doctors determine the result by comparing the conditions. In SPT, the doctors put a small drop of possible allergen on the skin and prick the skin with a needle to see the reaction. If a person is allergic to the allergen, he/she may observe a wheal, itching, or redness in the area. However, the doctors determine the results based upon the time and place of the symptoms he/she is complaining of.
Blood Test: Blood test is an excellent tool when the patient cannot give successful skin test. Blood tests are referred by the doctors in the cases when the patient is taking some medicines that interfere with the skin test or to the kids who cannot tolerate skin test. The blood sample is obtained by the doctors, and an allergen is added to the sample. The lab doctors observe whether there is any reaction in the sample due to the allergen.
Treatment:

The best way to fight house dust mite allergy is to avoid allergens. The doctors suggest measures to keep the surrounding dust free and use the covers or sprays that kill dust mites. The dust mites thrive in warm and humid areas. Hence, one should keep the surrounding cool and open to stop their growth. Many patients do not get complete relief from allergies with medicine, and in such cases, doctors provide special therapies and sprays to keep the dust mites away.

Conclusion:

There are many treatment options available depending upon the severity and condition of the allergy. However, it is best to consult a doctor before opting for any treatment or medicines.

House Dust Mite Allergy - All You Should Know!

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.

Diet, Nutrition & Ayurveda Treatment For Allergic Rhinitis!

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

Nuts are a rich source of energy but are also one of the most common food allergens. Both children and adults can suffer from nut allergies. While some children may outgrow the allergy, for others this is a lifelong condition. When it comes to children, the sibling of a child who is allergic to nuts also has a high risk of being allergic to them as well.

Nut allergies can be categorized as an allergy to peanuts or an allergy to tree nuts. Tree nuts are nuts that grow on trees such as walnuts, cashew nuts and almonds. Peanuts are not considered tree nuts as they grow underground in the form of legumes. A person can be allergic to both types of nuts but it is not necessary that if you are allergic to peanuts, you should avoid almonds as well and vice versa.

There are laboratory tests to determine the types of food you can be allergic to but in most cases, you realize you are allergic to something only after consuming it. Some of the symptoms of nut allergies include:

Redness
Rashes
Tenderness of the skin
Hives
Swelling of the hands and feet
Sneezing
Runny nose
Sore throat
Watery eyes
Nausea
Vomiting
Stomach cramps
Diarrhea
Shortness of breath
Most of the symptoms that affect the skin and respiratory system can be relieved with the help of antihistamines. Cold compresses can also help relieve itchiness caused by nut allergies.
One of the most severe forms of nut allergies can result in Anaphylaxis. This can be described as the swelling of the throat so much so that the airways are blocked and it becomes difficult to breathe. It is often accompanied by swelling of the facial features and itchiness. The only way to relieve this swelling is with an adrenaline injection. This reduces the swelling and reopens the airways. The most common type of adrenaline injection is known as an epi pen.

Some types of foods that commonly contain nuts and should be avoided include baked goods, pesto, nougat, marzipan, soups, multigrain bread, honey, granola, sauces such as hot sauce and barbeque sauce, salad dressings and veggie burgers. Nuts are often also used as thickening agents and hence if you know you are allergic to nuts, pay attention to food labels before you buy any product and make it a habit to tell your server in a restaurant that you are allergic to nuts.
