No, it is not normal for a tummy tuck incision to be opening up, forming keloids, or have fluid coming from it 8 months after surgery. This could be a sign of a complication such as an infection, delayed healing, or a seroma (a collection of fluid under the skin). It is important to consult with your plastic surgeon as soon as possible to determine the cause of the problem and receive appropriate treatment. The time it takes for the incision to heal will depend on the severity of the issue and the treatment required. Treatment options may include antibiotics, wound care, and surgical intervention, such as removing keloid tissue or draining a seroma. Your plastic surgeon may also recommend additional measures to promote healing, such as avoiding strenuous activity or using compression garments. In general, it is important to follow your surgeon's post-operative instructions carefully and attend all follow-up appointments to monitor your progress and address any issues as soon as they arise. Prompt attention to any signs of complications can help prevent further problems and improve your overall outcome. Best of luck !
