Can Bariatric Surgery Be Reversed? Sleeve, Bypass & SIPS Explained

Can Bariatric Surgery Be Reversed? Sleeve, Bypass & SIPS in Focus

Many patients in Naperville, Oak Brook, La Grange, and throughout Chicago’s western suburbs ask: Can bariatric surgery be reversed?

The answer depends on the type of procedure you’ve had—or are considering. At University of Chicago | AdventHealth LaGrange Hospital, Dr. Jihad Kudsi, Medical Director of Bariatric Surgery, helps patients understand their long-term options, including revisions and reversals when needed.

Sleeve Gastrectomy: Not Reversible, But Convertible

• What it is:About 80% of the stomach is permanently removed.
• Can it be reversed?❌ Once the stomach is removed, it cannot be put back.
• Conversion options:✅ A sleeve can be converted to:

• Gastric Bypass(for reflux, weight regain, or diabetes)
• SIPS/SADI-S(for enhanced weight loss or diabetes control)
  • Ideal for:Patients in Burr Ridge, Hinsdale, and Downers Grove looking for a simpler surgery with potential to upgrade later if needed.

Gastric Bypass: Technically Reversible, Rarely Needed

• What it is:The stomach is divided and rerouted to bypass part of the small intestine.
• Can it be reversed?✅ Yes, but...

• Reversal is complex and riskier than the original bypass.
• It’s only considered in rare cases(e.g., severe complications or malnutrition).
  • Alternative:Often, a revision or conversion is a safer choice than a full reversal.
  • Best for:Patients in Oak Brook, Western Springs, or Elmhurst who need stronger metabolic effects for diabetes or severe obesity.

SIPS (SADI-S): Convertible but Not Easily Reversible

• What it is:A sleeve combined with a single-loop intestinal bypass (duodenal switch).
• Can it be reversed?⚠️ Very difficult. Because it alters both the stomach and intestines, reversal is extremely rare.
• Can be revised or adjusteddepending on symptoms or nutritional needs.
• Best for:Patients from Naperville, Lombard, or Willowbrook who need aggressive weight loss and diabetes control.

So, What If You Regret Your Surgery?

Most patients don’t—but if issues arise, revisions or conversions are often better options than reversal. Our team at UChicago | AdventHealth LaGrange has extensive experience managing:

• GERD or acid reflux after sleeve
• Weight regain years later
• Nutritional concerns or intolerance

• Sleeve gastrectomyis permanent, but convertible.
• Gastric bypassis reversible, but rarely recommended.
• SIPS/SADI-Sis not designed for reversal, but can be revised.

With the right guidance, you don’t have to fear the “what-ifs.” Every step is designed with safety, long-term success, and your evolving needs in mind.
