What is an allergy ?
Allergies are very common and increasing in India affecting around one in Five people at some time in their lives. Allergy is also one of the major factors associated with the cause and persistence of asthma. 

Seasonal allergies make life miserable for millions of Indian and people in living in this world.

What happens when you have an allergic reaction ?
When a person who is allergic to a particular allergen comes into contact with it, an allergic reaction occurs. This begins when the allergen (for example, pollen) enters the body, triggering an antibody response. The antibodies attach themselves to special cells, called mast cells. When the pollen comes into contact with the antibodies, the mast cells respond by releasing certain substances, one of which is called histamine. When the release of histamine is due to an allergen, the resulting swelling and inflammation is extremely imitating and uncomfortable

Causes of allergy
The most common causes of allergic reactions are :
Dust mites
Pollen
Food such as peanuts, cow’s milk, soy, seafood and eggs
Cats and other furry or hairy animals such as dogs, horses, rabbits and guinea pigs
Insect stings
Moulds
Medicines

Effects of Allergy on the body?
Depending on the allergen and where it enters your body, you may experience different symptoms. 
For example, pollen, when breathed in through the nose, usually causes symptoms in the nose, eyes, sinuses and throat (allergic rhinitis). Allergy to food usually causes stomach or bowel problems and may cause hives (urticaria). Allergic reactions can also involve several parts of the body at the same time.

The nose, eyes, sinuses and throat

When allergens are breathed in, the release of histamine causes the lining of your nose to produce lots of mucus and to become swollen and inflamed. If causes your nose to run and itch and violent sneezing may occur. Your eyes may also start to water and you may get a sore throat.

The lungs and chest 

Asthma can sometimes be triggered during an allergic reaction. When and allergen is breathed in, the lining of the passages in the lungs swells and makes breathing difficult. Not all asthma is caused by allergy, but in many cases allergy plays a part.

The stomach and bowel

Most stomach upsets are caused by richness or spiciness in food itself, rather than an actual allergy to it. However, foods that are most commonly associated with allergy include peanuts, seafood, dairy products and eggs. Cow’s milk allergy in infants may occur and can cause eczema, asthma, colic and stomach upsets. It may also lead to failure to thrive. Some people cannot digest lactose (milk sugar). This intolerance to lactose also causes stomach upsets but must not be confused with allergy.

The skin 

Skin problems such as eczema (dry, red, itchy skin) and urticaria (also known as hives) often occur. Hives are white, itchy bumps which look and feel like insect bites. Food may be a factor in some cases of hives and eczema.
