There are many types of seafood available for consumption. People who love eating seafood often order shellfish, which are seafood forms like lobster, crab, squids, octopus, oysters, clams or shrimps. Allergy to these types of foods can develop unexpectedly. People who have consumed shellfish in the past without having any problems can also have an allergy to this, out of the blue. This allergy can be very dangerous. Shellfish allergy can develop at any age, and the reactions are sometimes life threatening. It can be more severe every time it occurs.
Shellfish protein can be added to non-shellfish foods or added as ingredients in other foods as well. Hence knowing "what you eat" is imperative if you have had an allergic episode earlier. If a person is allergic to fish, then he is sure to show allergic reactions to shellfish too.
People tend to outgrow food allergies over the years, but shellfish allergies usually remain with the victims and last for the rest of their lives. Food allergies are different from environmental allergies. You may not be able to prevent it since you may not be able to take a medicine prior, to prevent an allergic reaction.
A very important component in shellfish and other seafood is the Omega-3 polyunsaturated fatty acids, which has been proved to be healthy for anyone. Since the consumption of seafood has increased the world over, more people are falling prey to allergies. One of the most common allergic reactions to eating prawns is the formation of hives which is an itchy red welt on the skin. Eczema is also an allergic reaction to eating shellfish.
As we are aware, the body's immune system works as a defense mechanism to keep the body healthy.

The symptoms of these allergic reactions can be many. Few are listed below:
Different reactions can occur in different people, and after eating different forms of shellfish. Each individual will show reactions in varying degrees.
