In addition to the high temperature in summer, mosquitoes are also annoying. Some people may get a small red bump after being bitten by a mosquito, while others may become horrible after being bitten. The bigger the mosquito blister, the more toxic the mosquito is? The truth: It depends mainly on the type of mosquito and personal sensitivity There is a saying online that "the bigger the mosquito bite, the more poisonous the mosquito is." Many people believe this statement. So what is the truth? Copyright image, no permission to reprint "After being bitten by a mosquito, symptoms such as wheals, papules, and itching will appear on the skin. What we often call mosquito bites are local allergic reactions of the skin." said Liu Ruiling, deputy chief physician of the Department of Allergy at Tianjin Medical University General Hospital. "The degree of inflammation after a person is bitten by a mosquito is mainly related to the type of mosquito and personal sensitivity." Liu Ruiling explained that when a person with an allergic constitution is bitten by a mosquito, a large amount of histamine and cytokines will be secreted in the body, which will trigger an allergic reaction. In mild cases, wheals, papules, and angioedema will occur, and in severe cases, systemic reactions will occur. In addition, the size of the mosquito bite is also related to the part of the body that is bitten. Loose connective tissue areas such as the eyelids, lips, and back of the hands are prone to edema after being bitten, and the mosquito bite will also appear larger. After being bitten by a mosquito, do not scratch it hard. Scratching will exert mechanical pressure on the local skin and also accelerate blood flow, which will aggravate the inflammatory response and cause the mosquito bite to become larger.
