Seafood is loved by people because of its special umami flavor. Many people living inland buy some fresh seafood every year during the seafood harvest season, because fresh seafood and frozen seafood have different tastes. People's common seafood includes prawns, crabs, shellfish, etc. What should some people do if their faces are swollen after eating crabs? This is a typical symptom of seafood allergy. Let's learn how to relieve it.

First, the symptoms of eating crab allergies

Some people will find some red pimples on their bodies after eating crabs. Skin allergic reactions caused by eating seafood such as crabs are usually called "rashes", and they are itchy and can't be grasped by hands. More serious ones are dizziness, vomiting, headache, head swelling, abdominal pain and diarrhea. This is a typical manifestation of eating crab allergy.

Second, what should I do if I am allergic to eating crabs?

1, if the allergic symptoms are mild, you don't need to take any medicine or special treatment. Don't worry, it will heal itself after 1 or 2 days. Of course, if you want to stop itching early, you might as well drink perilla water.

Practice: Take dried perilla leaves (available in Chinese medicine shops)10 ~12g, put them in a teapot, brew them with 500 ~ 600 ml of boiling water and drink them. This method has a miraculous effect on itching, wheal, papules and abdominal pain caused by eating seafood.

2. If the allergic symptoms are serious and the whole body itching is unbearable:

(1) Try taking common antiallergic drugs (such as loratadine). While taking anti-allergic drugs, you can also take vitamin C. Or you can also apply dermatitis flat ointment to the itchy skin with red rash.

(2) Or you can take Kairuitan or chlorpheniramine orally for antiallergic treatment, and at the same time, it can be treated with vitamin C and calcium gluconate. Triamcinolone acetonide cream can be externally applied locally.

4. You can't eat seafood such as crabs and shrimps during allergies, and don't eat greasy and spicy food.

5. If the allergic symptoms of crabs are very serious, such as dyspnea, cold hands and feet, palpitation, etc., you should go to the hospital immediately and explain to the doctor that you have eaten crabs before.

Third, precautions for eating crab allergies

1 Don't scratch itching with your hands, it will itch more and more. When scratching locally, the temperature will increase, so that more allergens will be released from the blood, which will worsen.

2. Do not apply hot compress after eating crabs. Hot compress once itches is another stimulus, because heat will dilate blood vessels and release more allergens.

3. Eat more fresh fruits and vegetables during allergies, eat less fried, fried or spicy foods, don't eat seafood and eggs, and eat more fresh fruits and vegetables rich in vitamins.
