Our bodies react to external factors in very strange fashion. Reaction of our body’s immune system to any allergen is called allergy. There are various types of allergies which have either similar or very specific symptoms. Though some of these symptoms may disappear with time, it is a good idea to keep a note of allergies one suffers from, so that these can be informed to the doctors in case of need.
Allergies are a common ailment in a person’s life. There are many types of allergies symptoms which may either be common or specific in nature. Some of these allergies symptoms fade away with time, but a few of them are very persistent.
They are a common ailment that nearly everyone faces sometime in life. They are our immune system’s reaction to any allergen. These allergens come from food we eat, air we breathe, things we touch, clothes we wear, cosmetics and toiletries we use and even the medicines we take; in short, from anything which our bodies reject. The external irritating factor is called allergen and the body releases histamines to fight these allergens and safeguard itself.
The severity of these symptoms can increase or decrease depending on the duration of exposure to allergen. Most of the time they are simple irritants but may prolong and become severe if the source of allergen is not determined and removed. Allergies symptoms may subside or continue depending on how the body reacts to different allergens. For some allergens the body stores information in form of ‘mast cells’ which fight the allergens and release histamines to protect the body when the allergens attack the body next time.
Just as there are various allergies like food allergy, environmental allergy (pollution, heat, dust, pollen etc), insect sting allergy, hay fever allergy, drug allergy, mol allergy, latex allergy, sinusitis allergy, cockroach allergy there are numerous allergies symptoms

Out of the various types of allergies, those caused by food and environmental pollution cannot be avoid. Food allergies symptoms occur within two hours of ingestion; delayed reactions happen in children. Some people develop symptoms like itching in mouth and throat after eating raw fruits and vegetables. The body considers these foods as its enemy and prepares antibodies to fight against the allergens. Though some of the symptoms may subside with time, there are some allergens that may cause repeated attacks. These include allergies to sea food, fish and nuts.
These may sometimes cause severe allergies symptoms like:
- swelling up of throat and tongue,
- difficulty in breathing,
