What Is Food Allergy? Food allergy occurs when person's immune system reacts badly against specific types of food. It is an unnatural response of a body towards a food triggered by immune systems of the body. If are allergenic to some specific food, then even a small consumption of that food can aggravate signs and symptoms of allergy breathing trouble, itching and digestive problems and can easily make you sick. Sometimes food allergy may produce life threatening symptoms known as anaphylactic reactions in which person can die immediately. After the consumption of allergic food person's immune system produce specific antibodies IgE to protect the body from dangerous effects of food which is also referred as self defense mechanism of the body. If next time someone consumes the same food then immune system reacts very badly and produce large amount of chemicals called histamines for self defense. The chemical histamine creates lots allergic signs and symptoms in different parts of the body including gastrointestinal tract, respiratory system, cardiovascular system and skin. Food allergy can be easily recognized like shin rashes, swelling of lips, tongue, throat and face, wheezing and abdominal pain. The degree of reaction depends from person to person another depending on how much of the allergen was ingested along with the strength of body's immune system. These symptoms develop immediately after eating specific type of food. Signs and Symptoms: Signs and symptoms vary from person to person some people and develop within few minutes after eating food. Some people feel just uncomfortable with symptoms like itching, tingling sensation in mouth, facial edema, nasal congestion, breathing trouble, vomiting, diarrhea and dizziness. But for other people these allergic reaction may be life threatening and the symptoms include airways obstruction due to swelling, severe breathlessness, sudden drop of blood pressure, tachycardia (fast pulse rate) and unconsciousness. Causes: Milk, peanuts, tree nuts, soy, eggs, wheat, fish are the most common food that induce allergic reactions. Many children in their early stage of life are allergic to soy milk, wheat and eggs which gradually vanish with age. There are some food that can never be overcome with the age like Sensitivity to shellfish and fish. Risk factors Family history: many people are highly susceptible to food allergies if allergies, asthma or hives runs in their family. Other allergies: Those you are allergic to one food then the chances of allergic to another food increases. Age: Children especially infants and toddlers are more susceptible to food allergies.

Tests and diagnosis Blood or Skin scratch tests are the commonest test for diagnosis of food allergy.
