Could Muscles Have Relaxed After Tummy Tuck?

Just based on your photos, it is impossible to give you specific advice or make a diagnosis.  You may have fluid collection or failure of the diastasis repair.  You should definitely discuss this with your surgeon.  

 

Good Luck.

Swelling can take months to resolve. Without a before photo, it would be difficult to say how your results look at this point. However, I think you may want to wait about 4-6 months before you judge your results. By that time, most of the swelling should have resolved so you’ll have a better idea of your results.

it is possible but I'd suggest you wait for at least 6 months to let the swelling all go down. Then talk to your surgeon about your results. When you see your surgeon next week, have them check out the area as well for a better assessment.

You may definitely want to ask your surgeon if your abdominal wall was tightened with sutures. I have found that one row in the mid line of the tummy may not be enough. However, a fluid collection may also be a reasonable cause. Going back to your surgeon will help you answer your concerns. 

Thank you for the question and pictures.

The fullness you have in the abdominal wall  area is either muscle laxity, adipose tissue, or seroma ( fluid collection). Exactly what is going on should be determined by direct physical examination ( examining you in the upright, supine and flexed positions).  Best wishes.
