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

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!

Pollen is a common trigger for seasonal allergies. It may manifest as runny nose, cough, sneezing, stuffy nose, swelling around the eyes, etc. People begin to feel the bite of pollen allergy during spring when pollination in plants begins.

Pollen allergy affects a vast majority of people, and over-the- counter allergy relief medication is big business. However, it must be noted that there is hardly any permanent cure for pollen allergy. Nevertheless, there are ways in which one can get relief from the symptoms.

What Is Pollen and How Does It Cause Allergy:

The microscopic granules contained in flowering plants are known as pollen. While almost all flowering plants have pollen, all of them don t cause allergies. Plants that have bright flowers can hardly trigger allergy symptoms. It is the tiny and dry pollen that comes from trees, weeds, and grasses that precipitate the symptoms. These granules blow in the wind and get into the respiratory system. This precipitates an immune reaction which produces histamines. These are the chemicals that cause sneezing, stuffy nose, itching, runny nose etc.

Pollens can traverse distances of up to about 100 miles from the source. Since different varieties of plants, trees and weeds pollinate at different times, the season of pollen allergy is quite an extended one. It calls for precautions to prevent allergies and medicines and means to counter the effects.

Pollen Allergy Relief:

Allergy medicines are the best way to get relief from allergy symptoms. Doctors suggest starting on these medicines even before the onset of pollination season. These medicines are known as Antihistamines, which counter the effects of pollen.

These medicines block the histamine receptors in the ear-nose-throat region and thereby nullify the effects of pollen. If a person continues to take antihistamines throughout the pollination season, he/she deny the histamines a chance to get attached to the receptors and precipitate symptoms.

However, if a person is already suffering from the symptoms, antihistamines will not be able to quickly stop the problem. It will also not be able to reverse the effects of allergies. However, it can surely prevent exacerbation of symptoms.

Doctors also suggest using nasal corticosteroids for at least two weeks before pollination season so that the symptoms can be kept at bay. They work by modulating the response of the immune system and thereby preventing the release of chemicals that trigger allergies. If people take these medicines before exposure to pollen, they may even stabilize the immune system and prevent it from reacting to pollen.

Quick Allergy Relief:

If a person has not been proactive enough to take allergy medicines before the onset of pollination season, one needs to fight out the symptoms. However, there are some home remedies that can help a person put up a good fight with the irritating symptoms. One can do regular nasal irrigation with saline water several times a day throughout the pollination season to get some relief from allergies.

Conclusion:

There is hardly any perfect treatment for pollen allergy. However, one can stay safe with antihistamines or corticosteroids starting before exposure to pollen. In case a person gets attacked by these pollen allergies, seeking an immediate help is always advisable and recommended. Following the preventing instructions will help a person to fight against these allergies.

Pollen Allergy - How To Get Relief From It?

The number of allergens are many and knowing what triggers your allergies can get complicated. The common triggers that are known to trigger allergic rhinitis are:

Moulds
Fungi
Pollen, the most common cause for allergies
Dust mites, and the faeces of dust mites that can cause severe allergic reactions
Cockroaches
Animal dander, which includes cat hair, dog fur, and may also include little flakes of skin
Avoiding the above mentioned triggers is more of a general guideline for the management of allergies. The lifestyle changes that you make to manage allergies:

Keep yourself hydrated at all times. Drink about eight to ten glasses of water every day. This will allow the mucous to be expelled with ease, if you experience any nose block.
During seasons like spring, when the amount of pollen in the air is at its maximum, limit your exposure. Try to stay indoors to avoid exposure to pollen or dust in the air.
Make it a point to take a shower before going to sleep as the residues of pollen and dust stuck to your skin are likely to make your symptoms worse.
Use fresh bedding and clothes every day. This will help to reduce your exposure to allergens.
Remove your carpets. Carpets are home to dust mites and pollen grains which become difficult to remove even with vacuum cleaners. Remove the carpets during the allergy season, and replace with hard flooring.
Keep windows and doors shut to avoid dust and pollen grains from entering the house and possibly causing allergies.
Avoid staying around pets. It that is not possible, then wash them at least once a week to reduce allergies.
Prevent inhaling cigarette smoke or smoking cigarettes. The smoke can be very harmful and can increase the risk of asthma in kids.
Avoid outdoor trips during seasons when the pollen count is high.

Allergies - Lifestyle Changes That Can Help Manage it!

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.
