Breast Reduction Surgery is a medium to large surgery with some risks, but the safety is generally controllable. A few patients may experience complications such as blood loss, insufficient blood supply, and bilateral breast irregularities. 1. Blood loss is the most common complication of breast reduction surgery. If the operation time is longer, more blood will be lost during the operation, and blood transfusion may be needed to correct it during and after the operation. 2. Surgery may result in insufficient blood supply to the remaining part of the breast, causing localized breast or nipple and areola necrosis. 3. After breast reduction surgery, it may result in both breasts not being the same size, as it is difficult to achieve absolute symmetry during surgery, and if the degree of inconsistency is large, a second revision will be required. Overall, breast reduction surgery is a routine surgery with controllable safety, and it is recommended to go to a regular hospital for the surgery.
