Best Surgery for Weight Loss – Sleeve Gastrectomy, Duodenum, Bariatric Surgery

Obesity in Colorado, one of the leanest states in the US, is on the rise. In fact 21% of the population are obese. Many people are now turning to weight loss surgery such as sleeve gastrectomy, bariatric surgery and duodenum switch surgery. When it comes to weight loss, there are a number of medical procedures available. But it’s important to research all options before making a decision. From bariatric surgery to gastric sleeve weight loss procedures, it’s crucial to understand the different operations and medical procedures first. 

Have you have tried to lose weight in the past, but failed over and over again? Weight loss surgery may be your best option to become healthier. 

Let’s discuss the best surgery for weight loss including:

  • The Lap Band 
  • Duodenum – Duodenal Switch Surgery 
  • The Gastric Bypass
  • Sleeve Gastrectomy 

Duodenal Switch Surgery – Duodenum

The Duodenum Switch procedure (also known as Duodenal Switch surgery) is a gastric reduction for weight loss. The Duodenum procedure is a relatively new operation, introduced in 2007. Designed to replace the D.S with less bypass of the small intestine, making this weight loss surgery less difficult to perform. The single anastomosis duodenal switch procedure (SADI) can help patients to lose weight.

This surgery carries optimistic results and is a good resolution of comorbidities. However, long-term results regarding nutritional deficiencies are yet to be determined. Additional research is required before the Colorado Bariatric Surgery Institute recommends this procedure to our patients. 

The Lap-band.

Developed in Australia in the 1990’s, this weight loss surgery was approved for us in the United States in 2001. The Lap Band procedure is one of the most common weight loss operations. A donut size band is fitted around the upper part of the stomach during a Lap Band procedure in order to create a pouch to restrict the amount of food you can eat. By reducing the size of the stomach, weight loss results are good with many patients experiencing a 50% loss of excess weight with low complication rates.

Gastric Bypass Surgery for Weight Loss

Only one third of weight loss patients have found Lap Band surgery to be effective. A third of patients had fair results after undergoing Lap Band surgery, and the final third did not see any improvement. Complications of slips, prolapses and erosion of the band are common. As a result, Lap Band weight loss surgery is now not a good choice for long term weight loss goals. Surgeons have now stopped giving new weight loss patients this option due to the low success rate when compared to other weight loss procedures. For patients who have found success with this particular weight loss surgery, we continue to monitor their progress and provide medical support and guidance.

The Gastric Bypass

This brings us to the two most common weight loss operations done today—the gastric sleeve weight loss procedures or sleeve gastrectomy, and the Roux-en-Y gastric bypass. Both of these weight loss operations have been around for over 25 years, and have provided long-term weight loss results with few complications.

Gastric Bypass Weight Loss Surgery

The gastric bypass procedure was first developed in the late 1960’s and is carried out in two parts. The first procedure involves making a small pouch out of the upper stomach. The pouch is small to restrict the amount of food the patient can consume. It also helps the patient to feel full while consuming less calories. The pouch will slowly stretch out to be about 25% of a normal size stomach, after 12 months. Then, the poach will stop stretching. The second part of the gastric bypass surgery involves a bypass to the second part of the intestine. This bypass is much shorter than the D.S but still leads to less absorption of food.

This procedure results in good weight loss, 70% of excess weight after 12 months, a good resolution for comorbidities. Resolution or improvement in these obesity-related illnesses and health problems such as type II diabetes, hypertension, obstructive sleep apnea, GERD, knee and back pain, can all be helped with weight loss surgery. This helps to improve a patient’s quality of life and overall health. 

It’s important to keep in mind that gastric bypass surgery can lead to nutritional problems. Supplements are taken post- operation to maintain a healthy diet.

The Gastric Sleeve Weight Loss Surgery

The sleeve gastrectomy procedure is the most common operation for weight loss. It is the first part of the duodenal switch operation. The D.S. operation was only performed on very obese patients during the 1990’s. However, this operation was considered high risk. To make the operation safer, it was split into two procedures. The first performed was a sleeve gastrectomy. The patient was required to lose weight before the second operation could be performed. The second procedure was an intestinal bypass.

Surgeons began to recognize that often the second procedure was unnecessary, as patients lost sufficient weight with the sleeve gastrectomy alone. Consequently, the sleeve is now the most common weight loss operation with good weight loss outcomes. It provides resolution or improvement in co-morbidities, such as type II diabetes, hypertension, obstructive sleep apnea, GERD, and knee and back pain. The gastric sleeve weight loss procedure has great results and few complications.


In conclusion, there are a number of weight loss operations available to patients who require surgery. If you have a BMI, body mass index of 35 or above and have obesity-related medical problems such as type II diabetes, hypertension, obstructive sleep apnea you may be a good candidate for a gastric bypass or a  sleeve gastrectomy. Or, if you have a BMI of 40 or more, you are likely to be a good fit for weight loss surgery. For a subtle approach to weight loss with effective results, choose Peak Medical Weight Loss Clinic.
