It has been 8 mos. Why is my stomach protruding and hard as if I’m pregnant? (Photo)

Dear MichelleMiMi,
I understand your concern. However, without a proper assessment, it would be difficult to determine what went 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.

From your photos and description it appears the contour that concerns you is likely from visceral fat. This cannot be addressed through a tummy tuck, but weight loss should bring improvement. It could possibly a fail of the diastasis repair which would require surgical intervention to correct.

If it is flat when you wake up and the protrudes as the day progresses, you may have some food allergies that cause your abdomen (large colon) to swell as you eats those foods. Bread and dairy are often the culprits. Your surgeon can tell if any excess fluid is present and needs to be drained. You can ask for an ultrasound to check if you want.
