Allergies are exaggerated immune response to certain substances. Food, pollen, insects, medicines are some allergens. Avoiding exposure to allergens and taking precautions are possible treatments.

What are allergies?

Allergies are an exaggerated response of the immune system to certain foreign substances such as food, pollen, medicines, etc. An allergic person's body will consider these substances as foreign and thus a response is produced, while a non-allergic person body considers these substances as harmless and shows no response.
The substances that cause these allergies are known as allergens. The immune system produces IgE antibodies to combat the allergens. Most of the allergies are non-threatening and can be treated or controlled using preventive measures.
Common allergies include asthma, hay fever, stomach upset, insect (bee) sting, etc.

Causes

Allergies are caused by mainly host factors and environmental factors. Host factors are genetic composition, sex, race, age. Environmental factors include a wide array of substances that are categorised as: Food allergies (fish, milk, shellfish, and wheat), Seasonal allergies (spring season allergies by pollen grains), Pet allergies (dogs, cats), Medicine allergies (penicillin, sulphate).
Many a times, the allergen cannot be detected and it becomes difficult to treat the allergic reactions. In such circumstances, it is better to diagnose the type of reaction caused and analyse the sequence so as to detect the allergy causing substance.

Symptoms associated with allergies

Symptoms shown in the body by the exaggerated immune response to an allergen are of a wide array. The inflammation of the tissues lining the skin, nasal passage, eyes, ears, throat produce different symptoms to various allergens. Hay fever due to pollen grains produces sneezing, wheezing, blocked or running nose, irritation in the eyes. Skin reactions (eczema) produces flaky, itchy, patchy, or red coloured skin.
Allergies due to food produce vomiting, loose motions, swelling of throat, mouth, face, lips, and tongue, tingling in the mouth, itching in the mouth. Insect sting causes swelling at insect sting, low blood pressure, restlessness, rashes, irritation, anxiety. Medicine allergies produce swelling of the mouth, lips, face and tongue, itchiness, wheezing, rashes.

Line of treatment

The first line of action, when allergy symptoms are seen is to visit a doctor. One has to avoid exposure to allergen immediately. In cases such as pollen allergies, it is not entirely possible to stop pollen exposure. Precautionary measures are to be taken in such cases. When an allergy reaction is developed to a medication, contact the doctor who prescribed the medicine and ask for an alternative.
Antihistamines are common medications given to treat allergies. These are to be taken only after consulting a doctor. It is advisable to stay away from pets or avoid consuming fish or certain foods if one is allergic to them.

Identifying what causes the allergies can be a challenge - sometimes by trial and error. Thanks for this useful post Vaish3, we all suffer from one allergy or the other - siva
