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.
What are the symptoms of seafood allergy? People often have a special kind of poisoning after eating seafood, which is characterized by allergic symptoms such as itchy skin, redness and edema.
However, these people may only be sensitive to certain fish. If you do subcutaneous experiments or monitor that there is no allergic reaction to eating seafood, you can still eat alternative fish or seafood without rejecting all seafood.
If you eat stale or rotten green skin red meat fish, it can cause poisoning; Pickled salted fish, if the raw materials are not fresh or pickled, contain more histamine, which can also cause poisoning after eating. People with allergies may also have poisoning symptoms if they eat a small amount of histamine.
Poisoning occurs quickly, often at 0.5~ 1 hour after eating, sometimes as long as 5 minutes, and for a long time as long as 4 hours. Symptoms are mild at onset, recovery is quick, and occasionally death occurs.
Often manifested as blushing, dizziness, headache, heartbeat, palpitation, chest tightness, shortness of breath, swelling of the face and lips, numbness of the tongue and limbs, nausea, vomiting, itchy skin and so on.
