Gastric Bypass Surgery Statistics: Weight Loss Success Rate

Patients who undergo laparoscopic Roux-en-Y gastric bypass (LRYGB) typically achieve 62-65% excess weight loss over time.

This means that a patient with a body mass index (BMI) of 45 could lose around 30-35 kg after surgery.

The weight loss achieved through gastric bypass is sustainable for up to two decades. Patients can lose most of their excess weight in the first 1-2 years after the surgery.

Studies based on long-term data suggest that at least nine out of 10 patients maintain at least 10% weight reduction from their baseline even after 20 years, 7 maintain about 30% and 4 maintain at least 30% in 12 years after surgery.

Gastric bypass results can improve significantly if patients carefully follow their doctor’s instructions.

Gastric Bypass Surgery Stats on Obesity-Related Conditions

LRYGB can also lead to significant improvements in various obesity-related medical conditions, such as –

  • Type 2 diabetes
  • Hypertension
  • High cholesterol
  • Sleep apnea

According to a study published by the National Institutes of Health (NIH), at least 83% of patients with type 2 diabetes experience remission or significant improvement in their diabetes after gastric bypass surgery.

Their fasting glucose and hemoglobin levels return to normal in these patients. The remaining 17% of patients exhibit marked improvement in these areas.

As per the study published by the American Journal of Hypertension, nearly 60-70% of patients registered significant reduction in obesity-hypertension. The researchers relied on post-operative data of up to ten years.

Similar studies conducted in the past demonstrate that 95% of patients with high cholesterol see their cholesterol levels improve after LRYGB.

80% of patients with sleep apnea experience significant improvement or resolution of their symptoms.

Gastric Bypass Surgery Statistics - How Does It Compare to Other Bariatric Surgeries

In terms of overall success rate, most people would consider long-term weight-loss and improvement in obesity-related medical conditions when they decided to take the bariatric surgery route. 

Laparoscopic Roux-en-Y gastric bypass is more effective than laparoscopic vertical sleeve gastrectomy and Laparoscopic adjustable gastric banding.

In comparison to LRYGB’s 62-65%, LVSG and LAGB result in about 47% excess weight loss.
