Is This Normal Swelling for 6 Months Po Tummy Tuck? (photo)

You look about right to me.  One thing you might consider is the numbness after tummy tuck surgery.  When you go to the dentist, the numb lip feel larger than it really is.  The same is true in your abdomen after surgery.  The lower part is numb and this makes you feel like it is swollen.  Do your best to be patient and I think some of this sensation will pass in the next six months to a year.  Good luck.

A set of preop photos and a side view that shows the abdomen (the posted side view is cut off) would be necessary to comment on the outcome. A tummy tuck can remove excess skin and fat, and tighten the abdomenal wall, but none of these items without limitation. 

When a person sits, the chest and pelvis are moved close together, and the abdominal wall tissues are not infinitely elastic, so the skin buckles and the fat seems to thicken. This may happen somewhat less in a patient your size who never had a TT and whose skin elasticity is better, but it happens to some extent to all.  You won't see pictures of swim suit models sitting. 

Please consider posting some before photos and more useful responses should be forthcoming;
