Eating seafood can easily lead to diseases. Excessive histamine in seafood can cause people's physical discomfort. A few people eat fresh fish or seafood because of their natural lack of enzymes that decompose histamine, which can cause allergies, some of which are manifested as pimples in some parts of the body (face, legs, arms, and even the whole body) accompanied by itching symptoms.

Seafood allergy is an allergic disease, which can be divided into acute and chronic. Patients with acute seafood allergy should pay strict attention to diet and avoid spicy, seafood and other foods; Patients with chronic seafood allergy will get worse after eating certain foods. Patients with chronic seafood allergy should be desensitized to allergens in time. In addition, patients should avoid scratching the affected part strongly, scalding with hot water and topical irritant drugs, and avoid eating animal protein food and seafood hair.
