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?

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.

How to Know if Your Child Suffers From Food Allergy

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!

An estimated 10 to 30 percent of people across the world suffer from Allergic rhinitis. Allergic rhinitis, more commonly known as hay fever, is a condition wherein the immune system overly responds to allergens resulting in inflammation in the nose. As you might be aware, an allergen is typically a harmless substance present in the surroundings causing an uncomfortable allergic reaction.

Following is a detailed account of the condition.

Symptoms-
Some of the most common symptoms of allergic rhinitis include,

Sneezing
Stuffy and runny nose
Persistent coughing
Itchy and watery eyes
Sore throat
Frequent headaches
Dark circles under the eyes
And, symptoms associated with eczema
Further, it also results in hives and excessive fatigue. An allergic person is likely to feel many of these symptoms within a few minutes of coming into contact with an allergen. Some symptoms, such as recurrent fatigue and headaches can only happen when there is long-term exposure to allergens. There are some people, who rarely undergo any signs, and this happens when a person is exposed to the allergens in massive quantities.

Causes of Allergic Rhinitis:
When the body comes in contact with the allergen, it triggers the release of histamine which is a natural chemical that defends the body from the allergen. This histamine can lead to allergic rhinitis and the associated symptoms which may range from a blocked or a runny nose to itchy eyes. Common allergens include pollen, dust mites, animal dander, grass pollen, and mold.

There are two variants of allergic rhinitis- seasonal and perennial.

Seasonal- Seasonal allergies usually occur during specific seasons owing to the response to outdoor allergens. For example, during a specific time in the year such as spring, the pollen can cause allergies in a person. Also, when trees and flowers release pollens during the fall and summer, seasonal allergic rhinitis can be seen on the rise.
Perennial- On the other hand, perennial allergens tend to linger all-round the year, and pet dander, mold or dust mites come under perennial allergic rhinitis causing allergens.
Diagnosing and treating allergic rhinitis-
When a person is suffering from minor allergies, a physical exam may be required. But a doctor may also perform some tests for identifying the best course of treatment as well as prevention plan for a particular patient. A skin prick test is one of the best ways to determine whether you have allergic rhinitis.

This health issue can be treated in a variety of ways which range from home remedies to medications to alternative therapies. Common medications include antihistamines, decongestants and nasal sprays and eye drops.

Staying away from a known allergen is the best possible way to prevent allergic rhinitis. When diagnosed, it is necessary to consult your doctor as the condition may sometimes lead to complications.

Allergic Rhinitis - Everything That You Ought To Know

What is allergic rhinitis?

Allergic rhinitis is defined as allergic symptoms in the nasal passage. Allergic rhinitis can be seasonal (occurring during specific seasons) or perennial (occurring year round). The allergens that most commonly cause seasonal allergic rhinitis include pollens from trees,grasses and weeds, as well as spores from fungi and moulds. The allergens that most commonly cause perennial allergic rhinitis are house dust mites, cockroaches,animal dander,and fungi or moulds. Perennial allergic rhinitis tends to be more difficult to treat.

How does allergic rhinitis occur ?

This condition occurs when allergens (allergy- causing substances) come into contact with the nose, and usually also the ears, sinuses, and the throat. When allergens come in contact with the lining of the nose and sinuses, they trigger the cells to release the chemical histamine, which causes the allergy symptoms described below.

What are the symptoms ?

Nasal congestion 
Sneezing 
Watery " runny nose" 
Itchy eyes,nose,or throat 
Puffy eyes or 'allergic shiners'
Post nasal drip 
Tears 
These symptoms may occur during a certain season or year long. They can occur at any age. 

What is the treatment for allergic rhinitis ? 

A number of medications ,including antihistamines, intranasal corticosteroids, and decongestants are available to control symptoms. Allergen immunotherapy could provide long lasting benefit. You can "train" your immune system not to react exaggerated to an allergen anymore.

Allergic Rhinitis - Signs That You are Suffering from it?

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.
