Gastric Bypass Surgery


Gastric bypass surgery can help you lose a significant amount of weight and establish positive long-term dietary habits. By rerouting the stomach, gastric bypass can limit calorie absorption, resulting in rapid weight loss. Dr. Liza María Pompa González and our team at LIMARP® in Tijuana, Mexico, use the latest technology to ensure that your treatment is as safe and successful as possible. This procedure is beneficial for patients who are obese and having difficulty losing weight with diet and exercise alone. As one of the more commonly performed bariatric surgeries, gastric bypass surgery can help you establish a healthy lifestyle and restore your confidence.

What is Gastric Bypass Surgery?

Gastric bypass surgery, also known as Roux-en-Y, divides the stomach into two different pouches: a small upper pouch and a much larger lower pouch. After the dissection, the smaller pouch is connected to the lower small intestine, while the small intestine is repositioned and reattached to both the upper and lower pouches. By creating a much smaller stomach, it restricts the amount of food you can consume, allowing you to rapidly lose weight. The best candidates for this procedure include patients who are morbidly obese with a BMI over 40 or struggling from serious weight-related health conditions such as diabetes, sleep apnea, and hypertension. During your initial consultation, Dr. Pompa will perform a thorough examination to ensure that you are a good candidate for this procedure.

How Does it Work?

During the first part of the procedure, Dr. Pompa will create an incision across the top of your stomach using laparoscopic technology and carefully divide it into two portions. Once the smaller portion has been removed from the majority of the stomach and upper small intestine (duodenum), she will staple the sides closed to create a pouch and connect the lower portion of the pouch to the small intestines (jejunum). This smaller pouch will be able to hold about a cup of food at a time, restricting the amount of food consumed and allowing you to feel fuller faster.

At LIMARP, we have performed more than 3,000 successful weight loss surgeries for patients from all over the world.

Once the small pouch has been effectively created, she will staple the lower portion of the stomach closed and reconnect the duodenum to the newly bypassed small intestine. By creating a smaller stomach that bypasses the duodenum and digests directly into the lower part of the smaller intestine, much of the food will not be processed, thus restricting the absorption of calories and nutrients.

What to Expect on the Day of Surgery

Prior to your procedure, Dr. Pompa will provide you with a list of pre-op instructions to follow, including a strict supervised diet to help prepare your body for surgery. 

On the morning of your procedure, it is vital that you do not eat or drink anything, unless otherwise directed by your doctor. Once you arrive at our surgical facility, you will be taken to a private room where you will meet your surgical team. They will answer any last-minute questions and provide a hospital gown and compression socks to wear. If necessary, our anesthesiologist can provide you with oral sedation beforehand to help you relax. After all the pre-surgical tests have been completed, you will then be taken to the surgical room and given general anesthesia. Once you are comfortably sedated, Dr. Pompa can begin the procedure.

Recovering from Gastric Bypass Surgery

Once the procedure is completed, you will be taken to a comfortable, private recovery room where Dr. Pompa will monitor you for the first few days before releasing you to go home. Because this procedure is considered major abdominal surgery, it is imperative that you follow your postsurgical at-home care instructions carefully to reduce your chance of developing complications.

As your stomach adjusts, you may experience discomfort, nausea, vomiting, constipation, fatigue, and some depression for the few weeks after your procedure. Resting, taking medications as directed, minimizing your daily activity, and following your post-op diet can help reduce any uncomfortable symptoms as your body recovers.

Since each patient responds to surgery differently, the rate of recovery varies from patient to patient, but in most cases, you can expect to return to work around two to three weeks after surgery. As nausea subsides and your appetite returns, you can begin to enjoy eating most foods around in about three to four months. The key to recovery is maintaining a healthy diet and being patient with your body as it adjusts.

Are There Any Risks Involved?

Patients who undergo gastric bypass surgery have a greater chance of developing:

  • Nutritional and vitamin deficiencies
  • Stomach stretching caused by overeating
  • Stomal stenosis (a narrowing between the stomach and small intestines)
  • Disintegration of stomach staples
  • Gallstones
  • Dumping syndrome (food digesting too quickly from the stomach to small intestines)
  • Prolonged digestive issues, such as nausea, diarrhea, and fatigue

Working with qualified healthcare providers and following their instructions can greatly reduce these risks.
