Upper tummy bulge - can I do anything about this? (Photo)

I would go back to your surgeon and be examined to see if the muscle tightening has weakened or come loose.

Thank you for reaching out with your concerns about an upper tummy bulge nine months following your FL tummy tuck. Your pictures are quite informative and help in assessing the situation.
From what is visible, the bulge could either be a collection of fat or potentially a hernia. My first recommendation is to consult with your original surgeon for a precise evaluation. If a hernia is suspected, an ultrasound might be necessary to check for any fascial defects.
In case it's not a hernia, we're possibly looking at either localized fat accumulation or a weakened abdominal wall. If a fascial plication (muscle tightening) was not performed during your FL tummy tuck, this could potentially contribute to weakening of the fascia and the subsequent bulge.
Therefore, revisiting your plastic surgeon for a thorough assessment is crucial. An ultrasound may indeed be required to determine the exact nature of the bulge. If the ultrasound results are negative, implying no hernia or significant fascial defect, then the focus might shift to lifestyle modifications such as caloric restriction and increased physical activity to address the issue.
I hope this guidance helps you in taking the next steps to resolve the upper tummy bulge you're experiencing post your FL tummy tuck.
Sincerely,
Dr. Katzen

Thank you for your photos and question. If your weight has stayed the same the bulge may indicate that your muscle repair has failed in the upper abdomen. I encourage you to visit with your surgeon for an examination.
