4 Weeks Post-Op TT My Body Involuntarily Stretches, Is this Normal?

At this point, you are well on your way to healing so an involuntary stretch is unlikely to cause a problem.

After 4 weeks you pretty much can do whatever you want so if your body stretches or pulls whatever you should be fine.

Thank you for your question.

I don't know if I am understanding your question properly.. are you meaning that while you are sleeping you are straightening yourself out? I advise my tummy tuck patients to resume their normal activity slowly after the 4 week mark if everything is healing nicely.  It may be best to talk to your surgeon and see what he/she advises.
