Do you struggle with obesity? Are you considering surgical options? If you’re thinking about having weight loss surgery, you are likely thinking if a loop duodenal switch SADI-S or SIPS surgery) is the best option.

You may have read in the media or heard stories about this loop duodenal switch with sleeve gastrectomy (SADI-S or SIPS) has helped people drop a lot of weight and feel healthier, particularly if they have serious weight problems or health issues from being overweight.

However, what’s the truth? Check out what Dr Harald Puhalla has to say.

What Is Loop Duodenal Switch Surgery?

The loop duodenal switch surgery is a weight loss procedure that combines two techniques:

  1. Sleeve Gastrectomy: This surgery takes out a big part of the stomach about 80% so it’s smaller. This helps you feel full after eating just a little bit.
  2. Single Anastomosis Duodeno-Ileal Bypass: In this surgery, a part of your small intestine is moved. This helps your body absorb less from what you eat, which helps with losing weight

How Effective is Loop Duodenal Switch Surgery?

Studies show that SADI-S surgery works really well:

  • Weight Loss: Most people lose 75% to 95% of the extra weight they had, with most of the weight that usually lost between 12 and 18 months.
  • Type 2 Diabetes Improvement: About 96% of people said that their type 2 diabetes gets much better or cured in one year.
  • Long-Term Results: After 10 years, most people have still maintained the 80% weight loss.

What To Expect During Recovery?

Recovery from SADI-S is a gradual process. 

  • Hospital Stay: Most patients return from hospital within 1–2 days.
  • Dietary Changes: Right after surgery, patients only start with a liquid diet, then slowly move to eat soft foods, and then normal to solid foods
  • Supplements: After surgery, patients need to take special vitamins and protein supplements every day for the rest of their lives. So they don’t miss out on the nutrients their body needs.

After getting the SADI-S surgery, many people feel a big improvement in their daily lives. They say it’s easier to walk and do things, and problems like sleep apnea and high blood pressure often go away.
