Bariatric Surgery Weight Loss – What to Expect

Bariatric surgeries often result in long-term weight loss success. Studies vary but most suggest that the majority of patients do reach their weight loss goals and report a higher quality of life. The amount of weight loss after surgery depends on many factors including the type of surgery and the patient’s commitment to lifestyle changes. Patient participation is the key to achieving long-term success. According to a survey conducted by the American Society for Metabolic and Bariatric Surgery, patients who complied with doctor recommendations lost about 35% more weight, and were more likely to keep it off, than those who did not follow medical advice as strictly. Only about 10% of patients experience long- term weight gain. In addition to weight loss, bariatric surgeries often improve, or even eliminate, obesity- related health conditions such as Type 2 diabetes, high blood pressure, sleep apnea, and heart disease.

Lap-Band Weight Loss Results

Lap-Band patients generally lose weight more slowly in the first couple years than gastric bypass and gastric sleeve patients; however, studies reveal that they achieve comparable total weight loss after 10 years. Lap-Band patients generally lose anywhere from 25% to 80% of their excess body weight. Allergan, Inc., the maker of the Lap-Band, promotes that their surgical solution is a slow, steady, and safer means for long-term weight loss. According to studies published on its website, after 12 months, Lap-Band weight loss patients lose, on average, 47.5% of their excess weight and reduce their BMI by 8.9 points. The majority of patients maintain weight loss at the second year. Allergan reports that obesity-related health conditions show significant improvement after 12 months as well. Improvements or resolutions were evident in 93% of patients with pre-existing asthma, 90% with Type 2 diabetes, 93% with sleep apnea, 90% with gastro reflux, and 79% with hypertension.

Gastric Sleeve & Gastric Bypass Weight Loss Results

Initial bariatric weight loss is more rapid with gastric bypass and gastric sleeve surgeries than with Lap- Band gastric banding. By 18 months after surgery, Roux-en-Y gastric bypass weight loss patients lose an estimated 50% to 70% of their excess body weight. Gastric sleeve patients should expect to lose 30% to 50% of their excess weight in the first 6 to 12 months, and a total of 50% to 70% of their excess weight by year 2. Gastric bypass patients are likely to maintain 50% of their weight loss for 10 years or more. Gastric bypass results also show significant, and more rapid, improvements in obesity-related conditions with 70% of patients with improved hypertension and 90% of patients with improved or resolved Type 2 diabetes. While data suggests that long-term results are comparable by 10 years post surgery, gastric bypass patients report a slightly higher total average weight loss than patients with only gastric banding.

Great Expectations: Weight Loss After Bariatric Surgery

Post-Bariatric Surgery Weight Loss - What to Expect

In this video, Dr. Steve Poplawski discusses expected weight loss amounts for patients after bariatric surgery.  Using a bell curve graph, Dr. Poplawski diagrams what the expected percentage of excess body weight loss will be and what are some of the driving factors that determine where on the curve a patient will fall. Dr. Poplawski suggests that the average gastric bypass patient can expect to lose about 65% of her excess body weight and that the average gastric band / Lap-Band patient should see between 40% and 50% excess weight loss. He further illustrates that patients who outperform…

  • What surgery did you have? I remember feeling this way. Mine was related to not having a regular system yet. I have struggled with digestive health.

It is like Metamucil, but tastes much better and the powder does not clump. I buy it at CV...
