Our Board-Certified Surgeon Explains
What to Expect With a Gastric Bypass
For some people who struggle with obesity, diet and exercise just aren't enough to achieve healthy weight loss. Gastric bypass surgery is a tried-and-true method of helping patients control their appetites and lose weight.
Techniques and technology have been improving steadily over the last 55+ years, and the procedure is one of the safest and most reliable gastric procedures available today.
Dr. St. Laurent explains how laparoscopic gastric bypass surgery benefits patients who have developed significant underlying medical conditions as a result of obesity.

“My first appointment was very insightful. I left the office confident, informed and empowered to make the right choice for my health.”

Consultation
Dr. St. Laurent will complete a thorough analysis of your medical history and conduct some tests to determine whether gastric bypass or another type of bariatric surgery is right for you. If you both mutually agree to move forward with surgery, your gastric procedure will be scheduled.
Preparation
Carefully follow all of Dr. St. Laurent's instructions. Practice healthy habits, like quitting smoking and limiting your alcohol consumption. Refrain from certain medications, especially ones that make it difficult for your blood to clot, like ibuprofen and aspirin. You'll also need to make arrangements for someone to help you around your home after your bariatric surgery.
Anesthesia
When the day of your weight loss surgery arrives, the first step will be to put you under general anesthesia so you are fully asleep during the procedure.
Incisions
Next, Dr. St. Laurent will make several small incisions in your abdomen to access your stomach and small intestine. He will insert a laparoscope and small surgical tools through the incisions.
Stomach Division
Dr. St. Laurent will divide your stomach into two separate sections using surgical staples, ensuring that the upper section, which will contain food, is much smaller than the lower section.
Rerouting the Intestine
After separating your stomach, a portion of your small intestine will be connected directly to the upper pouch, allowing food to pass directly through it.
Close Incisions
Once the small intestine is connected to the upper pouch, the gastric bypass is complete. Dr. St. Laurent will remove his tools and stitch the incisions shut. The entire procedure, including connecting your small intestine to the upper pouch, usually takes between one hour and 90 minutes.
Recovery
Generally, an overnight hospital stay is required after gastric bypass surgery. Dr. St. Laurent will monitor your progress and release you when you can walk short distances comfortably and eat a reasonable amount of your diet.
Once you are released, you will need to limit your activity for up to two weeks. After that time, you can gradually increase your activity level over the next few weeks. You will also need to modify your diet, gradually adding in solid foods until you can tolerate them easily. Most patients return to a normal diet and activity levels in around six weeks.
Healthy Weight Loss
After you are fully recovered, it is important to eat a healthy diet and lead a healthy lifestyle to achieve the best possible weight loss results. At our office in Houston, Texas, we continue to support our patients well after their bariatric surgeries with nutritional and psychological counseling. As you continue to work with us, you should experience noticeable weight loss within six months.
We Minimize the Risks
Associated With Gastric Bypass Surgery
Like any surgical procedure, gastric bypass surgery could cause an infection or excessive bleeding. There's also a chance that the stomach or intestines could be damaged during the procedure. Gastric bypass surgery is uniquely associated with a complication known as "dumping syndrome." When food passes from the stomach into the small intestine too quickly, it can cause nausea, vomiting, and diarrhea.
By choosing Dr. St. Laurent, you greatly reduce your chances of encountering any of these issues. He has completed thousands of surgeries and uses the safest, most precise technology during every procedure. Dr. St. Laurent will also give you detailed instructions after surgery so that you can avoid dumping syndrome.
How Our Team Ensures
Comprehensive & Long-Term Results
In addition to providing a customized lifestyle plan created by our full-time dietitian, Michelle, our practice helps gastric bypass patients by providing:
Emotional Support
Dr. St. Laurent believes that obesity is a disease — not a moral failing. This philosophy led him to complement weight loss surgery with psychological help to achieve the best possible results. He and his expert team will work tirelessly to help you conquer any emotional and mental obstacles holding you back from a healthier lifestyle.
Body Contouring
Gastric bypass results in incredible weight loss. Unfortunately, this can also lead to loose skin, wrinkles, and stretch marks that develop after the rapid reduction in weight. We provide various thermal and laser-based body contouring procedures that you can undergo to eliminate these cosmetic concerns, allowing you to feel even more comfortable in your new body.

"I really thought I would struggle...but when I chose to take the guidance of Dr. St. Laurent and Michelle seriously instead of like a suggestion, it wasn't a terrible transition."
