Options Tailored to You and Your Goals

Our physicians, nutritionists and wellness experts work together to personalize a plan that's focused on lifestyle changes that you can maintain for the long term, providing you with ongoing medical supervision and support. It all starts with a personalized consultation to determine your best option, whether it's advanced bariatric surgery or a customized non-surgical program.

Surgical Options

Gastric Bypass Surgery (or Roux-en-Y)
  • Holy Name's second most-performed weight loss surgery
  • Reversible option uses an adjustable band to limit food intake
  • Safe and effective procedure with very little risk of complications
How it Works
  • Stomach is divided into two parts: one, a small pouch about the size of an egg, and the other, a larger remnant section
  • The pouch, which can now hold only a tiny amount of food, becomes the primary stomach and is connected directly to the lower small intestine
  • Food flows through this new, primary stomach directly into the small intestine, bypassing the larger remnant section of the stomach
  • This "new" digestive track reduces tolerance of weight-gaining fats and refined sugars
Results
  • Patients report a loss of 25-30% of body weight within 12-18 months after surgery
  • Weight loss is also reported in most patients 10 years after the procedure
  • Patients must take daily vitamins
Robotic Sleeve Gastrectomy (or Gastric Sleeve)
  • Most-performed type of bariatric surgery in the U.S.
  • Minimally invasive procedure reduces stomach size, helping you eat less and lose weight
  • Not reversible
  • Popular procedure because it results in less hunger, enabling better food choices, stabilizing the metabolism and promoting a healthier lifestyle
  • Safe and effective procedure with little risk of complications
How it Works
  • Surgery is performed with a one-night stay in the hospital, with most patients returning home the following day
  • Most patients can sit up soon after surgery with little to no discomfort
  • Removes 80% of the stomach, leaving a narrow "sleeve-like" section about the size and shape of a small banana
  • The "new" small stomach holds about 4-5 ounces of food at one time, reducing food consumption, which results in weight loss
  • Digestion and absorption of food and nutrients is not affected
Results
  • Most patients see 20-25% weight loss after surgery
Lap Band Surgery
  • Simplest of the bariatric surgeries doesn't interfere with normal digestion
  • Reduces stomach size and reroutes the digestive system to minimize calorie absorption
  • Adjustable and reversible
How it Works
  • Limits the amount of food a person can eat to about half a cup at one time
  • Silicone band is wrapped around the upper part of the stomach, dividing the organ and squeezing it into an hourglass shape
  • By adding fluid to the band, the surgeon adjusts the opening size between the smaller upper pouch and the remaining lower portion of the stomach
  • Band adjustments are customized for each patient and performed in the physician's office in the months following surgery
  • Because food lingers in the small, upper part of the stomach, digestion occurs slowly; patients feel full faster, stay satisfied longer and experience gradual weight loss as a result
Results
  • Most patients lose 10-15% of their body weight within two years after surgery
Duodenal Switch (SADI-S
  • Reduces stomach size and reroutes the intestines to maximize weight loss while limiting calorie and fat absorption
  • Helps reduce weight by restricting food intake and calorie absorption
  • Safe and effective procedure
  • Not reversible
How it Works
  • Removes two-thirds of the stomach, which ends up taking the shape of a tube or "sleeve"
Results
  • Most patients lose 40% of their body weight within two years after surgery
  • Clinical trials have shown sustained weight loss 10+ years after surgery
  • Requires consistent medical follow-up for vitamin, mineral and protein level observations
  • Some patients report increased frequency of bowel movements and gas

Non-Surgical Options

If you are seeking alternative options to lose weight or manage a chronic condition like diabetes or high blood pressure, non-surgical medical weight loss solutions can help you reach your goals safely and effectively while improving your overall health and well-being.

Endoscopic Sleeve Gastroplasty (ESG)
  • Minimally invasive, outpatient method reduces the stomach's capacity
  • Option for patients who may not be candidates for more invasive surgical procedures or those looking for a less invasive approach to weight loss or who don't want to be on weight loss medications indefinitely
  • Ideal for people with a BMI between 30 and 50
  • Reversible
How it Works
  • Endoscope (flexible tube with camera) is fitted with stitching tools into the stomach to reduce the stomach's size by 70%
  • No incisions are made; the endoscope reshapes and sutures the stomach
  • Promotes sense of fullness, reduces food intake
Results
  • Patients can expect to lose 15-20% of their body weight within one year
  • Patients can reverse the procedure if they wish to in the future
GLP-1 (Glucagon-Like Peptide-1)
  • GLP-1, a hormone naturally produced in the intestines, plays several important roles in regulating glucose metabolism and appetite
  • Taken by injection or medication to mimic effects of the body's own GLP-1
  • Reduces hunger and promoting feeling of fullness after eating
Other non-surgical methods include:
  • Medical weight management: Physician-guided plans using FDA-approved medications when appropriate to support weight loss and metabolic health
  • Nutritional counseling: Personalized meal planning and one-on-one sessions with registered dietitians to develop healthy eating habits
  • Behavioral support: Coaching and counseling to address emotional and psychological factors that may impact weight loss
  • Fitness guidance: Customized exercise plans designed to increase physical activity safely and effectively
  • Ongoing monitoring: Regular check-ins to track progress, adjust plans and provide motivation
