What is Allergic Asthma?

Allergic asthma is the condition in which the symptoms of an asthmatic attack appear after exposure to certain allergens. 90% of the cases of asthma in children are allergy driven, while in adults, the percentage is said to be around 50%.

An allergy happens when an individual's immune system exhibits massive reaction or fights vigorously against substances like pollen, dust, animal dander or certain other minute particles which are actually not harmful to the body but are considered so by the immune system.

Symptomatic changes in cases of allergic asthma:

If the symptoms of an asthma attack occur only when you are subjected to these triggers or irritant particles, your case is allergy driven.

In such cases, the airway reacts aggressively to the entry of such allergens.

The airway muscles tighten up and inflammation is observed.

Breathing becomes painful and compromised, and mucus accumulation sets in very quickly.

Coughing is a common phenomenon, as the body tries to expel the mucus accumulated.

The allergens mentioned above are not the only triggering agents. Basically, anything that causes irritation could trigger an allergy and an asthmatic attack thereafter. Symptoms in the case of allergy driven asthma are more or less the same as seen in other asthmatic cases.

Confirming the cause of asthma as allergic or not:

The doctor would give you a much better clarification on whether you're asthma is allergy driven or not. There are pretty much two ways to decipher the same:

One is to administer a tiny amount of allergen to the skin and making a note of the reaction to that. Whether the reaction is a normal one or an aggressive one would tell if an individual has an allergy or not.

Specific IgE test may be done to confirm the cause, or to test the presence of an allergic reaction in the individual.

All your queries pertaining to allergic asthma and asthma, in general, are more than welcome.

What is Allergic Asthma?

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!

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.

Best Substitutes for Common Food Allergens

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!

Allergies are a reaction of your immune system to any foreign matter, such as pet dander, pollen or bee venom, and not everyone is affected in the same way.
Antibodies are substances produced by your immune system to protect you from harmful invaders that can cause infections or make you ill.
The immune system produces antibodies when it comes into contact with allergens. Your immune system can recognise any allergen as threatening even if it s not. As a result, your skin, airways, digestive system or sinus gets inflamed.
Allergies can vary greatly in severity from mild irritations to anaphylaxis (a likely life-threatening emergency). Allergies are mostly incurable; however, there are various treatments available to alleviate allergy symptoms.
Causes-
Common triggers of allergy include:
Airborne allergens, such as mould, dust mites, animal dander and pollen.
Certain foods, especially milk, eggs, shellfish, fish, soy, wheat, tree nuts and peanuts.
Insect bites, such as wasp stings or bee stings.
Medications, specifically penicillin-based antibiotics or penicillin.
Latex, or any allergen you touch, causes skin infections.
Symptoms-
Symptoms of allergy depend on its type.
Hay fever (allergic rhinitis) symptoms include:
Sneezing
Itching of the roof of the mouth, eyes or nose
Stuffy, runny nose
Swollen, red or watery eyes (conjunctivitis)
Symptoms of food allergy include:
Tingling mouth
Swollen throat, face, tongue or lips
Hives
Anaphylaxis (a critical, deadly allergic reaction)
An allergy caused by insect stings can manifest in symptoms such as:
Swelling at the site of the sting
Hives or itching
Breathing problems, wheezing, coughing or chest tightness
Anaphylaxis
A drug allergy can lead to symptoms such as:
Hives
Itchy skin
Rashes
Facial swelling
Wheezing
Anaphylaxis
Atopic dermatitis (skin allergy) symptoms include:
Itching
Reddened skin
Peeling or flaky skin
Treatment-
Treatments of allergy include:
Avoiding Allergens: Your doctor can help you take necessary steps to recognise and avoid the allergens that trigger allergies. This is usually the most relevant step in the prevention of allergic reactions and reduction of symptoms.
Medicines to Lower Symptoms: Eye drops, nasal sprays or oral medications are commonly prescribed to reduce reactions and alleviate symptoms.
Immunotherapy: If the allergy is severe or other treatments fail to relieve symptoms, allergen immunotherapy is recommended. In this treatment, you get injected by a number of clarified allergen extracts over the years.
Emergency Epinephrine: If your allergy is severe, your doctor will provide you with an emergency epinephrine shot that you can carry with you everywhere. 

Allergies: Causes, Symptoms and Treatments

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.
