Does having Lipo on your abdomen tighten your vagina?

No liposuction of the abdomen does not tighten your vagina.  There are various procedures, surgical and nonsurgical for vaginal tightening.  Discuss these options with your gynecologist.

You should not expect that lipo would tighten your vagina. You may be thinking of what may happen if you remove a lot of fat from the Mons Pubis area. In this case you might experience some tightening but not enough to consider this a benefit from an alternate procedure. Good luck.

There is no relation whatsoever!  These are entirely separate anatomical systems. You may wish to discuss this with your gynecologist.
