Food Allergy: It is extremely important for people who have true food allergies to identify them and prevent allergic reactions to food because these reactions can cause devastating illness and, in some cases, be fatal.

FOOD ALLERGIES

Food Allergy is an immune system reaction that occurs soon after eating a certain food. Most food-related symptoms occur within two hours of ingestion; often they start within minutes. In some very rare cases, the reaction may be delayed by four to six hours or even longer. 

A food allergy can trigger a severe allergic reaction called anaphylaxis. Emergency treatment is critical for anaphylaxis. Untreated, anaphylaxis can cause a coma or even death.

If you are allergic to a particular food, for example, you may first experience itching in the mouth as you start to eat the food. After the food is digested in the stomach, abdominal symptoms such as vomiting, diarrhea, or pain may start.

  • When the food allergens enter and travel through the bloodstream, they can cause a drop in blood pressure.

  •  As the allergens reach the skin, they can induce hives or eczema, 

  •  When they reach the lungs, they may cause bronchospasm (wheezing or constriction of the lungs).      All of this takes place within a few minutes to an hour.

Not everyone who experiences symptoms after eating certain foods has a food allergy or needs to avoid that food entirely; for instance, some people experience an itchy mouth and throat after eating a raw or uncooked fruit or vegetable. 

The most common food allergy signs and symptoms include:

  • Tingling or itching in the mouth
  • Hives, itching or eczema
  • Swelling of the lips, face, tongue and throat or other parts of the body
  • Wheezing, nasal congestion or trouble breathing
  • Abdominal pain, diarrhea, nausea or vomiting
  • Dizziness, lightheadedness or fainting


Anaphylaxis--In some people, a food allergy can trigger a severe allergic reaction called anaphylaxis.

This can cause life-threatening signs and symptoms, including:

  • Constriction and tightening of airways
  • A swollen throat or the sensation of a lump in your throat that makes it difficult to breathe
  • Shock with a severe drop in blood pressure
  • Rapid pulse
  • Dizziness, lightheadedness or loss of consciousness


Many food allergies are first diagnosed in young children, though they may also appear in older children and adults. Food allergy can strike children and adults alike. While many children outgrow a food allergy, it is also possible for adults to develop allergies to particular foods. Foods, mostly  responsible  for the majority of allergic reactions include:

  • Cow’s milk
  • Soy
  •  Eggs
  •  Fish
  •  Peanuts
  • Shellfish
  • Wheat
  • Tree nuts 
The Food  itself isn't harmful, but the way your body reacts to it is.

To diagnose a food allergy a doctor must first determine if the patient is having an adverse reaction to specific foods. This assessment is made with the help of a detailed patient history, the patient's diet diary, or an elimination diet.

An allergist / immunologist, often referred to as an allergist, is a pediatrician or internist with at least two additional years of specialized training in the diagnosis and treatment of allergies, asthma, immune deficiencies and other immunologic diseases.

Yeah! Online education is being blamed as a miss concept of financial burden, even when we are supposed to learn by our computer, laptop or any other such developed media. This is because we are being claimed the online expenses even we are not supposed to pay. Hence, government should operationalize.
