Benefits of biliopancreatic diversion/duodenal switch

There are several benefits to be had from this surgery. These are as follows:

This procedure guarantees the greatest amount of weight loss as compared to any other obesity procedure. It is also the most durable as well.
Dramatic weight loss. You are looking at 70-80% even 90% in some cases. This tends to happen in the first year after the surgery and slows down in the second and subsequent years.
Not likely to experience ‘dumping syndrome’ (very rare).
You will be able to eat bigger and so more ‘normal’ sized amounts of food than with many of the other procedures such as gastric bypass for example.
This procedure can reduce or even cure many obesity-related conditions such as stroke, Type 2 diabetes, sleep apnoea, asthma, arthritis and back pain, liver disease, high blood pressure, raised cholesterol, heart disease and fertility problems.
Improved sense of confidence and well being. Psychological health will also improve.

These are all positives which will resolve your excess weight problems especially when combined with a healthy lifestyle.
