Metabolic & Bariatric Surgery

Are You a Candidate?

Bariatric landing central.jpg Bariatric surgery is a medically proven way to treat obesity and has helped many people live more fulfilling, active and healthier lives. But it is part of an entire process of change.

You may have already tried to lose weight through diet and exercise, and these major lifestyle changes haven’t worked. You might want to be able to play with your kids, climb the stairs again, and you wonder if you’ll have support before, during and after bariatric surgery.

That’s why our entire team is here: for you. The OSF Saint Francis Surgical Weight Loss Center participates in the Metabolic & Bariatric Surgery Quality Improvement Program (MBSQIP), and is committed to high-quality standards for its surgical procedures and the complete lifestyle assistance that accompanies them. This section prepares you for weight loss surgery and explains the different surgical options available at our center.

Bariatric surgery changes your digestive system by limiting how much you can eat, or by changing how you absorb nutrients, or both. The result of these procedures and continued support is that, over time, patients can lose up to 60-80% of their excess body weight.

It’s because our expert team is comprehensive, coordinated and focused on your well-being that we are:

  • The only accredited center in Peoria
  • The only team with a designated fellowship-trained surgeon in the area (FASMBS)

Accreditation from the American College of Surgeons (ACS) Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) formally acknowledges our commitment to providing quality care and maintaining excellent short- and long-term outcomes.

  • Bariatric Surgery Center Mission

  • The goal of the OSF Saint Francis Bariatric Surgery Center is to provide excellent, personalized, care for patients requesting weight loss surgery. We strive to assist you in achieving a realistic goal weight, a positive attitude about your health and an overall improved lifestyle. By adhering to the recommendations and guidelines of the American Society for Bariatric Surgery, we look forward in helping you in your journey for a longer, healthier life.

    Because proper weight control management requires a motivated patient and continued support, we offer a multidisciplinary program for healthy weight loss. We provide a wide range of services led by an integrated team of specialists who will explain every procedure and help you achieve long-term success.

  • Our Services

    • Weight-loss surgery
    • Bariatric surgery (either first-time surgery or addressing a previous bariatric surgery)
    • Gastric bypass/sleeve
    • Revisional bariatric surgery
    • biliopancreatic diversion with duodenal switch

  • Advanced, Minimally-invasive Procedures

  • OSF Saint Francis is focused on reducing the pain of surgery as much as possible. That's why we specialize in minimally invasive laparoscopic techniques, including:

    These procedures represent the latest advancements in bariatric surgery. With less pain, a lower rate of complications, a shorter hospital stay and a quicker return to normal activities, these procedures let you begin a new lifestyle sooner.

    • Roux-en-Y Gastric Bypass Surgery– is the most frequently performed and most researched weight loss surgery in the United States. During this procedure, a small stomach pouch is created by stapling part of the stomach and part of the intestine is attached to this pouch. Food bypasses a section of the intestine and reduces calorie absorption. The smaller stomach pouch limits the amount of food that can be ingested, so an altered diet and smaller portion sizes become a part of the lifestyle change. As part of this process, hormonal changes also occur that affect metabolism, hunger levels, and blood sugar control. 

    • Vertical Sleeve Gastrectomy– is recommended as a restrictive surgery and is performed as an alternative to Lap Band surgery. A portion of the stomach is removed and the remainder is formed into a sleeve without any intestinal detachment (re-routing). A smaller stomach causes patients to eat less but still feel full. An altered diet and smaller portion sizes are part of a lifelong change needed with this procedure. Because a portion of the stomach is removed, this surgery is not reversible.

  • Weight Loss Benefits

  • The medical and emotional benefits of bariatric surgery begin almost immediately. Over time these benefits can include:

    • Sustained weight loss

    • Improvement or resolution of Type 2 diabetes

    • Lower blood pressure

    • Lower cholesterol

    • Improvement of sleep apnea

    • Improved mobility

    • Reduced osteoarthritis pain

    • Higher energy level

    • Improved self-esteem

  • Becoming A Patient

  • The first step is to send our team a message  speak with our bariatric coordinator  to schedule a consultation. From there, you'll meet with a program surgeon to determine what kind of surgery is best for you. You'll learn about available surgical procedures, possible side effects and how your habits will have to change. A strong determination and commitment to changing your lifestyle partnered with education are the primary tools you will need to be a successful candidate.

    We also encourage you to attend and participate in our free monthly support group, where you can talk with other patients who have had weight loss surgery. Support group details can be found on our  Support Group page .

    In the months leading up to surgery, you will meet with our team monthly (either individually or in a group). You will track your eating and exercise habits to prepare you for the changes needed after weight loss surgery, and also learn key life-long habits for surgical success.

  • Post-Surgery

  • After surgery, your lifestyle will need to include a healthy diet, regular exercise and adherence to a comprehensive follow-up schedule. Within six to eight weeks, most patients return to a normal diet. You will need to chew your food well, eat slowly and refrain from drinking with your meals.

    Although you should be able to eat most foods after surgery, some food intolerance may be experienced. Your hospital stay after gastric bypass surgery or sleeve gastrectomy will range from 1-2 days,. You will need between one to six weeks off work following surgery depending on the amount of lifting and physical activity associated with your job and your surgeon's recommendation.

    You can also attend monthly support groups to connect with other people who have had weight loss surgery.

    In addition, you can participate in our long-term bariatric clinic to check your latest vitamin levels, meet with our team to keep you on track with your diet and exercise plan, answer any medical questions and more.
