Why do I have eczema after eating fish?

If an individual eats fish and develops blister-like rashes that weep and crusts over, he/she is experiencing an allergic reaction to fish. It is estimated that fish allergies affects millions of individuals all over the world. A distinctive symptom of allergy to fish is the manifestation of eczema along with other skin rashes after eating particular seafood. It is important to note that fish allergy can also progress to an allergic reaction that can even lead to death.

Close look on fish allergies

In most cases, fish allergy occurs once the body perceives the proteins in fish as a threat to the body. The immune system overly reacts to these proteins and starts to defend the body by producing IgE antibodies that fights off the fish proteins.

The IgE antibodies trigger a reaction in the body that causes other chemicals to react, resulting to the distinctive allergy symptoms. Take note that eczema can develop as a result of fish allergy in some individuals. Fish allergy is also connected to anaphylaxis which is a severe life-threatening reaction that abruptly develops. If the individual experiences dizziness, shortness of breath, rapid heart rate, hives and confusion, call for emergency assistance right away.

What is eczema?

Eczema is considered as a lasting skin condition in which the skin is highly sensitive to a variety of triggers that can cause the rash to flare-up. Just like with other allergies, the skin overly reacts to certain substances that trigger swelling, inflammation and itchiness.

If the individual experiences dizziness, shortness of breath, rapid heart rate, hives and confusion, call for emergency assistance right away.

This skin condition is quite common among children but can last a lifetime, affecting adults. The usual triggers of eczema include extreme cold or heat, airborne allergens, stress and food allergies. If an individual is allergic to fish, he/she might experience an outbreak of eczema after a few minutes of ingesting seafood.

The irritation in the skin can cause flare-ups of eczema. If the individual eats fish and ends up with an allergic reaction, large amounts of histamine are released into the skin, resulting to inflammation. After a few minutes after eating fish, spots around the mouth start to develop as well as on the face or other parts of the body. These spots slowly develop into itchy bumps that are filled with fluid. If the individual scratches the bumps, they will ooze and leave the skin prone to infection.

Management

The treatment starts by avoidance of fish in the diet. The minor symptoms of fish allergy typically respond to over-the-counter antihistamines and can help improve eczema.

Once eczema develops, you have to apply a cold compress over the affected area to minimize the itchiness and swelling. You can also apply hydrocortisone cream to keep the rash under control. In addition, avoid wearing tight-fitting clothing and keep the skin properly moisturized.
