  • Nine months post-op.

    • The nine month mark depends on your weight loss at the six-month check in. If you lost a significant amount of weight at the six-month mark, your doctor will set a reasonable goal to hit, such as an extra two to five percent of your weight.
  • One year after surgery.

    • At this point, most patients have lost about 60 to 80 percent of their weight depending on their starting weight.
