The main dangers of breast augmentation include infection, breast sagging, and encapsulation spasm. When the above symptoms appear, it is recommended to consult the doctor in time for treatment under the guidance of the doctor. 1. Infection: it is more common after breast augmentation surgery because breast augmentation surgery is an invasive surgery. If the principle of asepsis is not done properly during the operation or the local care is not paid attention to after the operation, it will lead to the symptoms of local infection, which will lead to the symptoms of local redness, swelling, pain, pus and other uncomfortable symptoms. 2. Breast sagging: If the hospital you choose is not a regular plastic surgery hospital, the implant will be implanted under the mammary glands due to the doctor’s improper operation or lack of experience, and breast sagging will occur after the operation. It is necessary to consult the regular hospital in time and re-open the surgery under the doctor’s guidance. 3. Peritoneal spasm: If the quality of the implant chosen is not qualified, it will cause stimulation to the local tissues of the breast or mammary gland after implantation, thus peritoneal spasm occurs, and it is recommended to consult a doctor in time for treatment.
