Why skin rashes develop after eating shrimp?

If the individual develops skin rashes after eating shrimp, he/she is most likely to experience food allergy. It is a known fact that allergies to shrimp are one of the most prevalent food allergies. Shrimp are a variety of shellfish that have a casing. Shellfish consist of both crustaceans and mollusks such as oysters, clams, squid, abalone, lobster, shrimp and crab. Skin rashes develop as an initial response that must not be ignored. If you suspect that an individual is allergic to shrimp or other foods, a doctor must be consulted. Tests will be carried out to determine the exact cause of the allergy.

How an allergic reaction occurs

Always bear in mind that an allergic reaction to any food starts due to an erratic immune response. There are certain proteins present in shrimp that are erroneously identified by the immune system as dangerous to the body. This triggers an immune response to generate antibodies that will attack the protein. When the individual is exposed to the shrimp protein in the future, the immune system releases histamine which is the substance that is responsible for developing the skin rashes and other accompanying symptoms.

What are the symptoms?

An allergic response can trigger skin rashes in a span of minutes up to a few hours after consumption of shrimp. The reaction to shrimp tends to vary in which the mild symptoms include the development of skin rash and itchiness. In case of a severe reaction, the individual can develop other symptoms including swelling of the lips, mouth, face and tongue as well as hives.

An individual who is highly allergic can also develop wheezing and a feeling that the throat is closing, making it difficult to swallow or breathe.

An individual who is highly allergic can also develop wheezing and a feeling that the throat is closing, making it difficult to swallow or breathe. This is considered as a serious scenario that entails immediate medical care. If the individual develops skin rashes after consumption of shrimp, he/she must not eat again until the allergy has been confirmed. Allergic reactions can end up worse after each exposure.

What happens during a severe reaction?

It is important to note that shrimp and other shellfish are main triggers of anaphylaxis which is a severe allergic reaction. Anaphylaxis is considered life-threatening which involves the whole body, resulting to the release of histamine from all the tissues in the body.

The symptoms of this reaction develop at a quick pace which includes confusion, abdominal cramps, slurred speech, confusion, wheezing, vomiting, difficulty breathing, rapid heart rate and fainting. If this reaction is not treated right away, it can progress into coma and even death. This is a medical emergency that require emergency assistance. Individuals who are prone to severe allergic reactions usually bring along an EpiPen wherever they go. If one is available during a severe attack, you have to administer a shot to counteract the symptoms. If you want to learn more on how to use an EpiPen, take a course on first aid at Vancouver today.
