Three months after bypass surgery, you can judge whether the sternum is healing by the color of the local scars and whether the scabs are reforming and shaping, and you need to consult your doctor in time to be examined under the guidance of a professional doctor. Three months after bypass surgery can be observed through the open chest surgery scar color becomes lighter, the volume shrinks, suggesting better healing. Generally the color of the scar is a good indicator of how well the wound as well as the sternum is healing. For patients with a median incision of the sternum, which is immobilized by wires after surgery, the bone scab, as the endpoint of bone healing, has a good indication of the healing of the sternum, and the bone scab needs to be examined by imaging to determine the healing of the sternum. After the bypass surgery, you need to have regular checkups, avoid physical activities until you have fully recovered, and take standardized medication under the guidance of your doctor.
