I have VERY puffy upper and lower abdomen 15 days post full Tummy tuck (no lipo). Is this normal? (photos)

You certainly seems to be healing as expected. I tell my patients they will notice the majority of there swelling settle over the first 6 weeks however they will notice increased swelling throughout the day for about 3 months. Try not to worry as you are still very early in your healing. You look great and will do well given adequate time.

It is normal at this stage to still be swollen.  We normally tell our patients to wait 3 months for the majority of swelling to be gone.  You look great, congrats on your surgery.

I am sorry to hear about your concerns after tummy tuck surgery. As always, it is best to be seen in person ( by your plastic surgeon) for precise diagnosis and treatment. Generally speaking, abdominal wall "swelling" after tummy tuck may be related to:
1. Swelling in the soft tissues. This may take several months to resolve and may worsen with increased activity or at the end of the day. Patience is required to allow for resolution of the swelling. The swelling occurs because of the interruption of venous and lymphatic channels that occurs during the tummy tuck operation.
2. Fluid accumulation in the space between the skin and the abdominal wall muscle. this may consist of blood ( hematoma) or serum (seroma). This fluid accumulation can generally be diagnosed by physical examination ( occasionally ultrasound may be helpful). Treatment consists of aspiration; several episodes of aspiration may be necessary.
3. Separation of the abdominal wall muscle repair may lead to a swelling/bulge appearance. This may be diagnosed on physical examination with your surgeon examining you in different bodily positions. One of the steps of a tummy tuck procedure involves reapproximation (plication) of the rectus muscles. These muscles have spread apart during pregnancy and/or weight gain. Bringing them together again in the midline helps to “tighten” the abdominal wall as well as to narrow the waistline.
4. Residual adipose tissue may be confused for swelling. Again this is most easily diagnosed by physical examination. Additional liposuction surgery maybe necessary to improve the results of surgery.
Generally, it takes many months for swelling to resolve after tummy tuck surgery and it may take up to one year (or greater) a complete skin redraping to occur.
I hope this helps.
