Generally it takes 3 months for the scar creation which is strong enough to hold your abdomen. However complete scar creation process and tissues remodeling is over after a year from the surgery.
After that time, if there is no hernia
, abdominal belt should be useless. However if it is still necessary in your case, it is possible that you still have a hernia present.
That is why I suggest you to visit general surgeon
, have physical examination and ultrasound
if any doubts.
You should also know that when you do wear abdominal belt, back muscles (so important for spine stabilization) are getting weaker and weaker. So such belt should be used only temporarily (when lifting or bending). And after 3 months of surgery it should be not used at all.
Hope this will help.
