Could Over Exertion be Causing Post Tummy Tuck Swelling?

Swelling of the lower abdomen is entirely normal at 6 weeks post op. Of course you need to be active with 3 young children, and it is great that you feel well enough to do your regular activities, as demanding as they are. Swelling, particularly in the lower abdomen will fluctuate with activity and often be worse in the evening than in the morning. This will improve over time. As long as the incision is healing and your surgeon does not feel there is a collection of fluid under the skin in this area, what you are experiencing is normal and will resolve.

Swelling normally takes a few weeks to subside. On average, most of the swelling goes away after about 3 months, and depending on the extent of surgery, this may even take up to 6 months. A full tummy tuck will involve a lengthier recovery period than a mini. During these weeks and months, you'll notice the swelling gradually lessening, although the rate at which this lessens can be affected by increased physical activity. So, yes, your activities may be contributing to the swelling. Please continue to wear your binder and talk to your surgeon for their advice.

I would give it more time....But it is not unusual to see swelling up to 6 months later after exertion...or for  no reason at all!!! But by 3 months you should have an idea!
