Center for Bariatrics
This procedure is also known as the Laparoscopic Sleeve Gastrectomy. It is done by removing about 80 percent of the stomach. The remaining portion of the stomach is a tube-shaped pouch that looks like a banana. The procedure works two ways. First, the amount of food (and calories) that can be consumed is reduced because the stomach is so much smaller. Second, the surgery has an effect on the hormones that control factors including hunger, feeling full, and blood sugar. Some studies show that this procedure is as effective as the gastric bypass in terms of weight loss and improvement in Type 2 diabetes.
During sleeve gastrectomy surgery the stomach is reshaped into a long tube or sleeve-like pouch that resembles a banana. The new pouch holds considerably less food, limiting your caloric intake and enabling you to feel satisfied after eating smaller meals. Since you are taking in fewer calories, you will experience steady weight loss after surgery. Another primary advantage of the sleeve is that it reduces production of the hormone that causes hunger. After a small meal, you will not feel hungry for hours; this makes it easier to follow your diet successfully.
Lap Band Surgery
In this procedure, a band is placed around the upper portion of the stomach. This creates a small stomach pouch above the band and the rest of the stomach below the band. With a smaller stomach pouch, a smaller amount of food will give you a feeling of fullness. The full feeling depends on the size of the opening between the pouch and the rest of the stomach. The size of the stomach opening can be adjusted by filling the band with sterile saline, placed through a port under the skin. The size of the opening is gradually reduced over time with additional adjustments. After this procedure, food is digested and absorbed normally.
This procedure is considered the gold standard of weight-loss surgery. It is the most commonly performed bariatric procedure in the world. In this surgery, a small stomach pouch is created by dividing the top of the stomach from the rest of the stomach. Then, the first part of the small intestine is divided and the bottom end of the divided small intestine is connected to the newly-created small stomach pouch. Finally, the top portion of the divided small intestine is connected to the small intestine further down so that stomach acids and digestive enzymes from the bypassed stomach and first portion of the small intestine eventually mix with food.
The newly-created stomach pouch is much smaller, which means that it is possible to eat smaller meals and consume fewer calories. Because the smaller stomach absorbs less food and there is also a segment of small intestine that no longer has food going through it, fewer calories and nutrients may be absorbed. The rerouting of the food system produces changes in the hormones that make you feel fuller and less hungry. Many people who undergo this procedure who have obesity-induced Type 2 diabetes find that the condition is reversed after surgery.
Gastric bypass accomplishes two things: first, it reshapes the stomach into a much smaller pouch, so it can hold less food. Then, it adjusts your digestive tract so the food you eat bypasses a portion of the small intestine (where calories and nutrients are normally absorbed). You will feel fuller after eating smaller meals, and your body will absorb fewer calories and nutrients. The result is rapid, steady weight loss.
Gastric bypass can improve or resolve obesity-related health conditions such as type 2 diabetes, high blood pressure and sleep apnea. Many of our patients enjoy improved health and freedom from pills and medications.
