Expected Weight Loss: Duodenal Switch
Weight loss surgery is a method of losing weight that is drastic and dramatic for most. It is a decision that has been come to with a great deal of discussion and decision making. One of the main factors in deciding if you want to go through a weight loss surgery is in knowing how much weight you can expect to lose.
While weight loss is sure to happen with the Duodenal Switch, there is no guarantee as to exactly how much each patient will lose or when. Some of the factors that will alter this number are how well the surgery goes, how much you adhere to a new nutrition and dietary plan and what type of exercise plan and life changes you follow through with. These are essential when it comes to weight loss and long term results from any weight loss surgery.
The average weight loss reported by surgeons and various studies in patients that undergo Duodenal Switch surgery is between 70% and 80% of the excess weight of that patient. This is true of patients that have long term follow up and that have made significant changes to their lifestyles. When considering these numbers it is important to realize that a success in bariatric surgery is actually realized when the procedure over 50% of loss in excess weight. The success rate for these surgeries is considered to be 80% according to studies.
The excess weight is determined when you take the current weight of the patient and subtract what is considered to be a healthy weight. Professionals use percentages when discussing weight loss because each patient can experience some type of weight loss and the amount of weight loss is personal to the individuals starting numbers and excess weight. Using the base excess weight number will allow you to determine your percentage of weight loss.
How Much to Expect
According to the Archives of Surgery, a study compared patients who had duodenal switch surgery with those who had gastric bypass surgery and found that sustained weight loss was more successful in duodenal switch surgery patients. Two years following their weight loss surgery, the average amount of weight loss that was both sustained and maintained by DS patients was 79% versus just 67% in gastric bypass patients. This study looked at 1,545 DS patients and 77,406 gastric bypass patients from 2007 to 2010.
The same study found that as many as 20% of gastric bypass patients failed to lose half of their excess body mass index or BMI at the one year follow-up mark as well as at their two-year appointment. While duodenal switch surgery patients only had a 9% and 6% failure rate respectively.
Duodenal switch surgery patients also have more success in the resolution of comorbidities such as high blood pressure, high cholesterol and Type II Diabetes. A study showed that an overall total cholesterol decrease of .24 mmol/L occurred in gastric bypass surgery patients, while a reduction of 1.07 mmol/L occurred in duodenal switch surgery patients.
Also low density lipoprotein, anthropometric measures, fat-free mass reductions and fat masses in general were more common in patients who had duodenal switch patients versus gastric bypass surgery. While both groups experiences glucose concentration reductions, C-reactive protein reductions as well as blood pressure reading reductions, there were no large difference between the groups. However, the results shown for the duodenal switch surgery patients were remarkable in terms of reduction of the need for medication and overall resolution of the disease in the long term.
