In reality, dust allergy is precipitated by dust mites, a kind of microorganisms that thrive in dust. They acquire their food from dead skin cells and absorb water from the environment and thrive. Moist and warm environments are ideal for them to thrive. However, they themselves don t cause allergic symptoms. 

It is the response of the immune system to them that precipitates the symptoms. Once they are inside the human respiratory system, the immune system responds to them in a negative way. This leads to the production of histamines, a kind of protein that abates swelling, cough, mucous production, runny nose, sneezing, etc.

Symptoms of Dust Allergy:

Dust allergies may lead to various symptoms, some of which may be short lived, while others may be chronic. Some of these symptoms may also be life threatening. While in general people may suffer from running nose, stuffy nose, sneezing, coughing, itchy eyes, postnasal drip, swollen skin under the eyes, etc., in severe cases, people may also suffer from asthma, chest pain and tightness, trouble in sleeping due to shortness of breath, bouts of severe cough, sinus infection, etc.

Risk Factors:

Some of the common risk factors are: 

Family History: People who have a family history of dust allergy are most susceptible to this problem. These people develop a sensitivity to dust mites.

Exposure: Exposure to dust mites is the main cause of dust allergy. If someone is exposed to dust mites for a long time, it enhances the risk of allergy symptoms.

Being a Child: Children are more susceptible to it than adults. They are more likely to develop allergies during childhood and early adulthood compared to adults.

Diagnosis:

Most dust allergy symptoms are similar to common cough and cold symptoms. This is why it is necessary to confirm that the symptoms owe their origin to dust allergy. As a primary physical examination, the doctor may examine the lining of nasal passage to see if it is swollen.

In case the person is allergic to dust or pollen, the lining of the nasal passage is likely to become inflamed. However, the doctor also needs to conduct some tests. He may conduct skin tests and blood tests to confirm the allergy. If the allergy is confirmed, the doctor goes for treatment.

Treatment:

There are a number of treatment options for dust allergy. Some of these may act as over-the-counter to counter the effects of dust allergy, while others may act as modulators to modulate the immune response.

Antihistamines: These are medicines that counter histamines responsible for allergic reactions like itching, runny nose, sneezing, etc.

Corticosteroids: Corticosteroids are usually delivered through nasal sprays to bring down inflammation and control the allergic response of the immune system.

Decongestants: They help to decongest nasal airways which get inflamed and swell up due to allergic reactions.

Leukotriene Modifiers: These medicines block certain immune system chemicals responsible for allergic reactions and prevent allergic reactions.

Immunotherapy: The doctor may go for immunotherapy if no other effort is yielding any results. This therapy trains the immune system so that it does not become sensitive to dust mites. It is delivered via injections.

Conclusion:

The primary defense against dust allergy is avoiding breathing in dust. However, if a person is already exposed to them, there are a number of medicines and treatment options to prevent a flare up.

Dust Allergy - Risks, Diagnosis & Treatment Of 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.

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

Can Food Allergies Be the Likely Cause of Your Infertility?

Infertility in a woman refers to the inability to conceive after having regular unprotected sex. Cases of unexplained infertility have been on the rise recently.  Though obstructed fallopian tubes and ovulation disorders are some of the common causes of infertility, reasons pertaining to dietary changes can also be responsible. Food allergies and dietary changes affect infertility to a great extent; and if you're struggling with conception or infertility, heeding to your diet can help.

Below is a list of diet constituents that are likely to cause infertility.

1. Gluten - Gluten is a protein found in grains like wheat, rye, and barley. Among the general population, women suffering from unexplained infertility have a higher incidence of gluten intolerance. Gluten intolerance is also related to miscarriages, and if left undiagnosed can lead to malabsorption of micronutrients like iron and zinc. Following and maintaining a gluten-free diet may relieve a sufferer from the symptoms. Try and include gluten free cereals like rice, corn and gluten free oats to manage the situation.

2. Inflammation - Another connection of food allergies and infertility would be inflammation. Inflammation occurs when the food allergens reach the stomach. This inflammation, if heightened, can cause damage to the fallopian tubes and the ovary. The body responds to the food allergens by treating it like a foreign substance that needs to be eradicated, and when your immune system is subjected to chronic inflammation, it can lead to infertility.

Additionally, apart from food allergies, even the consumption of certain foods and beverages can be a reason behind infertility, with those being rich in caffeine being a major cause. Increased consumption of caffeine can augment the risk of infertility and delayed conception. However, avoiding caffeine and eliminating problematic foods along with a careful scrutiny of your diet can increase your chances of getting pregnant.



Can Food Allergies Be the Likely Cause of Your Infertility?

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.

Nuts - How To Know If You Are Allergic To Them?

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!

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.
