Is it possible that my muscle separation became undone?

Hi,
Unfortunately, the first 6 months after muscle repair is the danger zone to where the sutures can be popped if the intra-abdominal pressure exceeds its threshold. However, the sutures used for this repair are usually VERY strong and are made to withhold force. It is very unlikely, but not completely impossible. I would go get assessed by your surgeon and even inquire if he uses continuous or interrupted sutures in his muscle repairs. In the meantime, I would be wearing very tight compression to support your abd wall.

Hello! Thank you for your question! It would be best to be assessed by your plastic surgeon who completed your surgery to examine you. The rectus abdominis muscles are sutured together during a tummy tuck. Rarely, the sutures can come apart when there is extra stress against the muscles, such as with vomiting. This would most commonly happen shortly after surgery. When this occurs, multiple pops can sometimes be heard and felt by the patient. I would generally expect that after four months that enough scar tissue has formed in the area that it would be less likely for separation to occur at that time.
