Could a sneeze pop my suture? (Photo)

It is unlikely that you have caused any suture damage from sneezing and it sounds like the bulge is due to a fluid accumulation. A seroma (or fluid collection) is a common and frustrating problem after a tummy tuck. I recommend being patient and wearing compression garments to help minimize the swelling. Your bulge should resolve when the fluid accumulation resolves. #tummytuck #recovery #seroma 

I think this is almost impossible. Nevertheless, if you have concerns visit your plastic surgeon and let him check the area in question.

Depending on what type of suturing was performed and what pattern it was in, it is possible that the force of a sneeze could pop a stitch. The fact that there is fluid there makes it more likely that it is just a fluid collection and not a popped stitch.

Snapping your sutures would be an extremely rare event from sneezing.  I all likelihood you would probably feel pop and an "immediate" bulge.  Your bulge description is consistent with a seroma.  Even after it resolves that area will have prolonged swelling and a potential bulge.  As long as the seroma goes way the bulge should disappear! 

Theoretically any forceful flexion of the abdominal muscles could tear one of these plication sutures.  Usually a sneeze would not do this, but it is possible-- your surgeon would know best how secure or tenuous the sutures were and if this is a realistic possibility.  Based on the fact that your surgeon is aspirating the area, perhaps he thinks a fluid collection such as a hematoma or seroma is more likely.  An ultrasound can sometimes help confirm a fluid collection or the separation of the suture line. Hope this helps!--Erik Hoy, M.D.

From what you're describing it doesn't sound like you popped a suture. More likely you have a small seroma, which is very common after tummy tuck. In order to help get rid of the bulge you need to limit your activity(bending at the waist) and continue wearing your compression garment. You may also need repeat drainage by your surgeon.
