TT with MR 5 months ago - not pleased with my results. Surgeon says it's visceral fat. It's squishy and a lot of skin (Photo)

There is no harm getting a second opinion. Pre operative photos would be helpful to determine what may be causing the abdominal contour. If it is visceral fat then weight loss is the way to improve your results. An exam would be needed to determine if further liposuction or skin removal is indicated.

Dear waggies,
I understand your concern. However, without a proper assessment, it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Based on your photos you have almost nothing of excess of subcutaneous fat, your problem is not that.
Your problem is the protruding appearance and the lack of shape around the waist. What you are pinching is excess of width and another skin resection won’t eliminate excess of width.
Your real problem is your muscle. You need to get redone the Tummy Tuck to tighten the muscle, I predict 5-6 inches muscle repair (13-15 cm), redrape the skin, may remove an extra inch of skin, no more, and create a beautiful smaller belly button and a tapered more curvaceous shape. .
I honestly consider you will have an awesome result!!
Be encouraged.
