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!

Dust mites belong to a family of ticks and spiders, and cannot be seen through bare eyes. They thrive in places which are warm and humid.

Dust mite allergies are the most common type of allergy found in many people. Patients suffering from house dust mite allergies may also face sneezing and a runny nose. The symptoms are just the same as asthma.

The best way to get rid of dust mite allergies is to make the house as much dust-free as possible.

In case a person is attacked by any of these dust mites, doctors may also suggest some medicines to suppress the symptoms and ease the condition.

Symptoms of House Dust Mite Allergy:

House dust mite allergy causing inflammation in the nasal passages may show signs like:

Watery eyes

Runny nose

Redness in the eyes

Sneezing

Congestion

Facial itching

Redness and skin spores opening

Face infection

If the allergy is contributing to Asthma, the following signs are observed:

Difficulty in breathing

Heaviness in the chest

Chest pain

Wheezing sound with cough and cold

Shortness of breath

The signs of a house dust mite allergy can be severe in some cases. However, allergies are not life-threatening, but prolonged symptoms may affect health. A mild allergy-like runny nose or sneezing are common. However, if a person is suffering from symptoms for a more extended period of time, he/she should consult an ENT specialist for the same.

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!

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.

10 Foods That Help You Fight Allergies

Silicosis is a lung disorder that develops as a result of exposure to dust, which has silica (chemical compounds) content. Silicosis significantly makes you prone to other serious health disorders. It is an incurable disorder and a prescribed dosage of medications in the form of cough syrups or antibiotics can help in the regulation of the symptoms. Inhalers are also useful to clear the blocked air passages. In extreme cases, the doctors might suggest a transplant of the lung to eradicate silicosis.

Causes
Silicosis is caused primarily due to a long- term exposure (usually 5-15 years) to silica. But a short-term exposure (for a few weeks or months) can also result in silicosis, which tends to worsen considerably as time progresses, if not diagnosed in its early stages. Silica is a natural dust particle, which is found in abundance in rocks, sand, bricks or concrete. Once silica gets into your body through inhalation, these particles tend to damage the tissues of the lungs by inflicting minor incisions. This considerably disfigures the lungs, thereby making the whole process of breathing rather troublesome. Long-term exposure to silica might further lead to lung cancer. People who work in mines, glass or asphalt manufacturing industries, iron and steel industries and construction sites are at increased risks of developing this condition.

Symptoms
The Symptoms of Silicosis begin mildly, but tend to worsen with time. The symptoms of Silicosis are as follows:
a. The initial symptoms include severe weariness, repeated instances of coughing and experiencing trouble while breathing. These symptoms usually recur as time progresses.

b. In the latter stages of silicosis, the symptoms gradually worsen accompanied by severe pain in the chest along with fever, night sweat and sudden loss of body weight.

Silicosis might make you susceptible to other infections related to the respiratory systems such as tuberculosis.

Prevention
In order to prevent Silicosis, you should wear suitable protective gear and a respirator on your face while working in a place which has risks of silica exposure.

Causes and Symptoms of Silicosis

Food allergies have been on the rise and many food items have been identified as potential allergens. Common items like citrus fruits, coconut, peanuts, tree nuts, gluten can cause allergies. You don't need to stay away from your favorite dish just because it contains one of the allergy-causing ingredients. You can customize your dish with suitable substitutions and enjoy your food without worrying.

Peanut

Peanut is one of the most common allergy-causing items. It has severe effects on people who are allergic to it. On its consumption, the throat of allergic person swells up, blocking the airways which can lead to anaphylaxis. So, for people who are allergic to this grain legume, peanut -laden cuisines like Thai food, peanut butter, and jelly are all prohibited. But you can replace peanut with sesame seeds, pumpkin seeds, and hemp which are available in butter form as well.

Citrus fruits

Lime, orange, lemon, and grapefruit have been seen to cause discomfort in both adolescents and adults. There are so many citrus-flavored drinks that it becomes difficult to find a nice harmless drink. But, if you are allergic to these fruits you can go for strawberry, raspberry, and apple-flavored drinks, which are easily available.

Coconut

Coconut is used in place of milk in vegan recipes; it can replace milk in food items like ice cream, sweet drinks, and curries. If you are allergic to coconut, substitute it with rice, soy, oats milk and even soaked cashews.

Wheat

Wheat is not only off limits to people with celiac disease who have to lead a gluten free life but for some who are allergic to wheat specifically. Pasta, bread and many other kinds of foods are made up of wheat, but you can opt for tapioca or rice flour which is also used to make such items.
