5 Weeks Post-op Tummy Tuck and I Feel Pouchy Again - Swelling or Stretched Muscles?

This is difficult to determine without an examination or physical examination or photo. It is unlikely that your muscles have loosened at 5 weeks and more likely that you are experiencing edema (swelling) or possibe seroma as the cause of your lower abdominal swelling. Improper wear of a garment can also contribute to this appearance

5 weeks postop from a tummy tuck is still early.  You still have swelling.  How much only time will tell.  You certainly would not do anything invasive at this point in time.  Continued use of a girdle, massage will help.  At 6 weeks I like to slowly reintroduce exercise as tolerated.

At 5 weeks many tummy tuck clients have started back with normal normal routines and too much activity can cause the fluid in the tummy stay around longer.  It is normal to still have some fluid in this area until the muscle and fat attach again.  Maintaining use of the tummy girdle can help with this situation as well as slowing some of your activity level until it goes away.  Most often at the 6-8 week period my patients are better with the operation and very few still have fluid in this area.  I recommend you follow-up with your surgeon at the 6-8 week time period if you are not any better.
