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!

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 trigger allergies
Some of the common foods that trigger allergies are:
1. Peanuts
2. Shellfish
3. Other forms of tree nuts such as almonds, walnuts etc.
4. Gluten rich grains such as wheat, rye barley, oats
5. Certain types of fish
6. Eggs
7. Soy products
8. Milk (allergic reactions mostly occur within children)

Some other foods which have been known to cause allergies in rare cases are:
1. Meats such as pork, chicken, beef, mutton
2. Corn and corn products
3. Gelatin
4. Certain spices such as mustard, garlic and coriander among others
5. Certain seeds such as poppy, sunflower, or sesame

Symptoms of allergies
In certain cases, the allergies might manifest immediately, almost in a matter of minutes, within the body. However, in many cases, it may take a few hours for it to show up. The symptoms may range from mild to quite severe. Mild symptoms will make it quite hard to actually diagnose it as a food allergy.

Some of the milder symptoms could be:
1. Hives or eczema could form on your skin which may be very itchy. These would look like raised swollen areas that could be red, inflamed, and dry.
2. The inside of your mouth and ears may become itchy
3. You could suddenly develop a runny or a blocked nose and start sneezing or coughing.
4. Your eyes may become watery, red and itchy
5. You may develop a funny taste in your mouth
6. Others symptoms may include throwing up and even loose motions

Other severe forms of allergies can be caused mostly by shellfish and peanuts and other forms of nuts and fish. Symptoms in such cases would look like:
1. Uneven heartbeat
2. Difficulty in swallowing and breathing
3. Feeling of extreme weakness, confusion
4. Passing out or feeling light headed
5. The tongue, throat or lips may swell up
6. Chest pain

Common Foods that Can Trigger 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!

While some people look forward to spring and the beautiful flowers that bloom, for others this is a time of extreme discomfort triggered by pollen allergies. Pollen is probably one of the most difficult allergies to fight as it is invisible and is literally present everywhere. Sneezing, coughing, a runny nose, congestion and watery eyes are the most common symptoms of a pollen allergy. However, you can minimise your troubles by following a few simple steps.

Keep an eye on the pollen count: Not every day has the same amount of pollen in the air. Pollen density is also affected by the time of the day. Pollen count refers to the amount of pollen present in the air during a specific time period. You can find out the pollen count of your area online or through a number of apps. Once you know the pollen count. You can plan your day accordingly and step out or stay in.
Plan your time spent outdoors wisely: It isn t always possible to stay indoors even if you know the pollen count is high. However, you can still plan your time so as to not be outdoors at peak pollen times. 5am to 9am are the worst times to step out as this is when most plants pollinate. Hence avoid stepping out during this time. Windy days can also worsen the situation by spreading pollen around. If you must go for a jog early morning, avoid thoroughfares and gardens and instead pick a route around residential streets.
Protect yourself: Face masks may not look very good but can help reduce the amount of pollen being inhaled. If you find yourself sneezing a lot during pollen season, consider investing in a painter s mask that can filter the air being inhaled and exhaled. If you are stepping out to do yard work or know that you re going to spend a lot of time in heavy traffic areas, take your antiallergenic medication before you step out instead of waiting for an allergic reaction to begin.
Have plenty of showers: Try making it a habit to have a shower and changing your clothes as soon as you come home. This prevents the outdoor pollen from circulating in your home. Follow this routine even if you ve simply been gardening outdoors. While showering, do not forget your hair. If you do not want to shampoo it every day, simply rinse it out to get rid of all the pollen.

Pollen Allergy - 4 Tips To Keep Yourself Safe!

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.
