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

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.

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

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