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.

4 Most Common Food Allergies

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. We can excuse it by calling it a common flu or a heat rash, but the reason behind it might be something you are not aware of. Your child might be allergic, and it is imperative for you to find out that exact thing your child is allergic to, it can be dust, nuts that you may think is beneficial for your child s health or even the fabric of the clothes you put on them. Allergies are caused when children come in contact with allergens, which can he inhaled, injected or even eaten unknowingly. If you see any of the symptoms of allergies, consult your doctor at the earliest and do not treat it lightly.

Some common triggers for allergies

These are divided into four groups

Foods: Certain foods like peanuts, eggs, milk and it products which you feed your child might be triggering their allergy.
Outdoors: When kids play outside pollens from trees or flowers might causes allergies. Even insect bites and stings are a major trigger
Indoors: Animal fur or hair and even dust mites and mold that exist in your house can trigger an allergy
Irritants: Common irritants like cigarette smoke, perfumes or even car exhaust should be watched out for.
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.

Common Allergies in Children - That You Need to Know!

Food is a very important part of your life as it provides all the necessary nutrients required by your body and is essentially, the fuel for all things to function within. However, many people may have aversion to certain kinds of food as it causes adverse reactions within their body. Let s look at some of the common food allergies that people commonly report and how to identify them.

Allergies v/s Intolerances: It is important to note here that there is a significant difference between food sensitivities or intolerances and allergies. Sensitivities or intolerances cause adverse effects on your body inevitably when you consume certain types of foods. One such example is diarrhea, caused by ingesting cheese or milk by lactose intolerant people. However, allergies are caused when the immune system within your body mistakes harmless food as something that might harm you and thus tries to protect you from its effects. This results in reactions within your body which may be very painful and problematic.

Common Foods that Can Trigger Allergy

It is no longer so surprising to read about alarming air pollution levels in our cities. On more than one occasion, these levels have risen above the danger levels. For some people, this may simply create an annoying fog that makes it difficult to see. For others, it can cause serious health issues. Air pollution is one of the most common reasons for the growing instances of asthma and allergies. Children are most susceptible to such diseases caused by air pollution.

Asthma and Allergies
Asthma can affect children even before their fifth birthday and the condition is characterized by breathlessness caused by a constriction of the airways. While the root cause of asthma is unknown, it is usually seen that asthmatic patients are more sensitive to others to particles in the air such as pollutants, dander, dust, smoke etc. Thus, the airways construct as a reaction to these allergens. Changes in the weather, a sudden cold draft or the flu can also aggravate asthma.

Can you Protect Your Children from Asthma?
Wheezing, panting, finding it difficult to breathe and a persistent cough are some of the signs of asthma. If you notice these symptoms, you must consult a doctor immediately. At home, here are a few things you could do.

Avoid exposing your children to smoke: Do not smoke around your children or allow others to smoke around them. If you cannot give up the habit, wear a smoking jacket when you smoke and take this off before you play with your children. When you ll go out, drive with the windows up so that your child does not inhale exhaust smoke. Set your air conditioner to circulate air within the car itself.
Dust often: Try and keep your home as dust free as possible. Use a wet cloth to clean so that the dust does not fly in the air. Wash all your bed linen once a week. Carpets and rugs should be vacuumed regularly or dusted outside. It may also be a good idea to invest in dust mite impermeable covers for your child s mattress and pillows.
Keep your Pets clean: If you share your home with pets, bathe them once a week and brush them daily. Do not let them climb on to the furniture or your beds. Also, avoid having their toys lie on your beds.
Wear a face mask: Try and time your child s outdoor activities when the pollution levels are low. Buy yourself and your child a face mask that will filter the air they breathe in. These should be worn whenever they play outdoors.
These simple steps could help your child be healthier and can prevent asthma and other such allergic reactions.

Increasing Asthma & Allergy In Children - What Should You Do?

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.
