Still have lower belly pooch - Is a tummy tuck revision needed? (photos)

I am 10 months post op. I am 5’5, approximately 168 pounds. I was 171 the day of surgery. I am working out but have definitely hit that age where it’s not as easy to lose weight. I was 43 at the time of the procedure. I am wondering if I need a revision. I still have a lower belly pooch and the left side of my abdomen is larger than the right. I discussed the size difference with my surgeon when I first noticed it but he said that it was nothing. It’s not aesthetically pleasing.
