Don't eat Chili, mustard, raw onion and garlic, fried food and other foods. Dilate capillaries and speed up blood flow. Don't eat allergic foods such as mango, kiwi fruit and pineapple. If it is a skin problem caused by sun allergy, don't eat light-sensitive foods such as spinach and rape, otherwise it will aggravate allergic symptoms.
Diet should be light, eat more fresh fruits and vegetables and drink more water to promote the excretion of allergic substances in the body, which is conducive to the recovery of the disease. Patients with severe allergic symptoms can not only pay attention to diet, but also take oral anti-allergic drugs such as cetirizine and chlorpheniramine. If the skin is itchy, red and swollen, accompanied by symptoms of palpitation and shortness of breath, you need to go to the hospital immediately for oxygen inhalation and intravenous infusion of antiallergic drugs.
