Environmental Allergens

The majority of people around the world are allergic to something or the other. Among the common triggers of allergic reactions include specific food types, pollen, dust, fungi and sometimes chemicals in medicines. Allergic reaction can cause mild irritation in some people and in some, they may be fatal. That is why it is important for people who have allergies to carry their anti-allergy medicines at all times. The best thing to do is avoid coming into contact with what you are allergic too.


What is it?

Allergies are the response of the immune system to a substance. When your body, the immune system to be precise, does not agree with something, you will experience an allergic reaction. Allergies are hypersensitive disorders, and when ignored, can lead to conditions like diarrhea, asthma, vomiting, sinusitis, and swelling of the face or other body parts.

Allergies are the over exaggerated reaction of a person’s immune system to a particular substance or particle. That is why something, that is good for you, may prove to be dangerous for another individual who is allergic to it.

While most allergies are developed at an early age, some people can become allergic to certain substances as they age. There is no saying what may cause the allergy or what they may become allergic to, but the most common factor causing an allergic reaction is changes in the immune system.

Treatment for allergies, therefore, include natural treatments, steroid injections and medicines that modify the structure of the immune system and minimize the reaction. People who are allergic to particles in the environment, like dust, pollen and such are more susceptible to their reactions.

 

Symptoms

The allergic reactions that people have can range from mild and fatal. The early stages of an allergic reaction could be acute and result in rashes, or running nose, itchy eyes, etc. that cause discomfort in the person. Severe allergies can lead to

  • Sneezing and running nose (Rhinitis)
  • Sinusitis
  • Coughing, some people may have an attack of asthma on exposure to allergens
  • Redness of the eye, itching and watering of eyes (Hayfever and Allergies)
  • Breakout of hives, rashes with inflammation of the skin
  • Vomiting and diarrhea
  • Bloating of stomach, pain in the abdomen

Often, the allergies may appear in the form of rashes or a common cold and may occur repetitively. In such cases, the first step is to identify what you are allergic to and also consult a doctor for preventive medication.


Causes

 Allergies can be caused due to

  • Foods like nuts, dairy products, fish, etc.
  • Non-food proteins like latex
  • Toxins that interact with certain proteins in the food
  • Hereditary (genetic structure causes allergies in some people)
