Urticaria, also known as hives, is swelling accompanied by itching and can appear in various shapes and sizes in one area or all over the body. When scratched, the bumps can spread to other parts of the skin.

Some people say that this hives factor can be caused by consuming seafood. Is it true and fact or maybe just a myth? Let's discuss it here.

According to Perdoski (Indonesian Association of Dermatologists and Sex Specialists), one of the causes of hives is consuming allergy-causing foods such as milk and its products, nuts or seafood. So it's true, eating seafood can cause hives.

How can someone be allergic to seafood? The immune system reacts to certain allergy triggers (allergens). The immune system produces antibodies that detect the allergen and cause an inflammatory reaction and the release of a chemical called histamine. Histamine causes itching, fever and other allergy symptoms.

Everyone's immune system is different, and Seafood allergies can cause symptoms that range from mild to severe. Many food allergies do not cause severe symptoms, but can be life-threatening and should be taken seriously.
