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!

Allergic rhinitis is characterized by symptoms of a runny nose, congestion, itchy eyes and sneezing. This disorder is usually caused by allergens such as pollen and dust. Commonly known as hay fever, allergic rhinitis may exhibit the following symptoms:

The symptoms of allergic rhinitis are:
1. You may experience a runny nose and congestion in the nose
2. You may have allergic conjunctivitis where your eyes turn itchy and watery
3. Persistent coughing
4. Symptoms of sneezing
5. Swelling may develop underneath the eyes
6. You may have an itchy nose
7. Constant signs of fatigue

Causes
Allergic rhinitis or hay fever causes the immune system to recognize certain airborne substances as harmful. The immune system in the body starts to form antibodies to combat these irritants. The antibodies cause the body to release  histamine , a chemical that triggers the symptoms of allergic rhinitis.

The various triggers that may cause allergic rhinitis are:
1. Dust mites
2. Tree pollen
3. Grass pollen
4. Spoors from outdoor and indoor fungi
5. Ragweed pollen

The treatment for this disorder is to avoid exposure to the triggers. Mild symptoms of this disorder may be treated with over-the-counter medications whereas severe symptoms may require prescription medications.
The various medications for allergic rhinitis are:

Antihistamines: Antihistamines may be administered as pills or nasal sprays; these medications can help with itching and sneezing. Antihistamines help in limiting the effects of histamine in the body.
Nasal corticosteroids: These prescription medications can help treat itching and inflammation in the nose. They are usually the first medications that are administered.
Decongestants: Decongestants are over-the-counter medications that can be used to treat congestion in the nose. You should be careful not to overuse these medicines as they can increase blood pressure.
Allergy shots: If medications do not relieve symptoms of allergic rhinitis, the doctor may prescribe allergy shots to treat the disorder. The injections contain allergens in small amounts which are injected over a period of time; this causes the body to get used to these allergens, resulting in a reduction of the symptoms.

Allergy - Best Ways Ayurveda Can Help Manage It!

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.

    Coughing

    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.
