I had a gastric bypass in 2003, then a tummy tuck in 2005. in 2012 i had bowl obstructions and had explo. surg. it feels like tuck was let loose.

Possible Hernia: You may have developed an incisional hernia from the exploratory surgery. Suggest you see your surgeon.

Careful: Your subsequent surgeries should not have caused your tummy tuck to "come loose". If you have a new bulge, the most important thing is to make sure you do not have an incisional hernia. See your bariatric surgeon who might order a cat scan to make sure. If you do not have a hernia, see your plastic surgeon who might be able to revise your tummy tuck if there is a significant amount of laxity.

Hernia or diastase: If an exploratory laparotomy was performed on an emergency basis, it is possible that a pre-existing diastasis that was repaired at the time of your abdominoplasty may have recurred. It is also possible you are experiencing an incisional hernia as suggested by the other physicians. It is difficult to make a diagnosis without imaging which should be considered after being examined by your surgeon.

More info: More info about the symptoms as well as knowledge of the details if the previous operation such as incision type and location, and a physical exam are really necessary to provide a reasonable answer to whether or not there is a serious problem or this is a normal postoperative sensation. You should see your surgeon it primary care doc to find out. Hope this helps.

Need Exam: Based on your description and history, it is very likely that during the exploratory laparotomy, the muscle repair done during the tummy tuck surgery was released. This may cause you to feel like the abdominal wall is lax again. Otherwise, you may have developed a postoperative/incisional hernia. Either way, in-person examination will be necessary for precise diagnosis and recommendations.
