Gastric Bypass Weight Loss: What to Expect and Timeline

Weight loss after gastric bypass varies by starting weight, age, sex, diet, exercise, and adherence to guidelines. On average:

  • 1–2 pounds per week during first 6–12 months
  • 1–2 years to lose 100 pounds

Weight loss is not linear; weekly variation occurs. Follow healthcare team recommendations, including regular follow-ups, for safe, successful outcomes.
