symptom

What are the symptoms of seafood allergy? People often experience a special kind of poisoning after eating seafood, which manifests as allergy-like symptoms such as skin itching, redness, edema, etc. However, these people may just be sensitive to certain fish. If a subcutaneous test is done or there is no allergic reaction to seafood under monitoring, you can still eat alternative fish or seafood without having to refuse all seafood.

Eating stale or rotten green-skinned red meat fish can cause poisoning; pickled salted fish, if the raw materials are not fresh or not pickled thoroughly, contains a lot of histamine, which can also cause poisoning after eating. People with allergies may also experience symptoms of poisoning if they consume small amounts of histamine.

The onset of poisoning is rapid, usually 0.5 to 1 hour after ingestion, sometimes as little as 5 minutes, and sometimes as long as 4 hours. When the disease occurs, the symptoms are mild, recovery is rapid, and death occurs occasionally. Common symptoms include flushing, dizziness, headache, palpitations, chest tightness, shortness of breath, swelling of the face and lips, numbness of the mouth, tongue and limbs, nausea, vomiting, and itchy skin.

Causes

The cause of seafood allergy is that seafood is rich in a large amount of foreign proteins, which directly or indirectly activate immune cells, causing the release of chemical mediators, and then produce a series of complex biochemical reactions. When antibodies and antigens work together, the human body shows allergic symptoms.
