  • Does not require an implantation, as opposed to the silastic ring used in gastric banding
  • The procedure decreases both the stomach’s size and the secretion of ghrelin, a hormone that stimulates appetite; the procedure removes the portion of the stomach that produces ghrelin
  • No malabsorption, No Vitamin or Mineral Deficiency
  • There are no cross-connections or reroutes of the intestinal tract
  • Less long-term maintenance than gastric banding
  • More weight loss than Adjustable Gastric Banding
  • Can offer the benefit of initially decreasing the body weight in the severely obese patient, to prepare him or her for another surgery at a later time

  • Sustained weight loss, in accordance with limited diet
  • Does not require the implantation of a foreign body, such as a silastic ring
  • More weight loss than in Gastric Banding
  • Less long-term maintenance than gastric banding
  • Offers both restrictive and malabsorptive effects
  • Major clinical database of information available

  • No stomach resection
  • No vitamin or nutrient definitions because of malabsorption
  • No cross-connections or reroutes of the intestinal tract
  • No protein-caloric malabsorption

  • No Surgery Required
  • The operation takes about 20-30 minutes to complete

  • Anemia may result from malabsorption of vitamin B12 and iron in menstruating women
  • Decreased absorption of calcium may bring on osteoporosis and metabolic bone disease
  • May cause dumping syndrome (condition in which stomach contents move too quickly through the small intestine.) Can result in nausea, weakness and sweating, faintness and diarrhea — especially after sweets
  • Potential for gastric leaks (due to stapled resection of the stomach)

  • Less weight lost compared to bypass or sleeve procedures
  • Risk of band slippage or erosion, which may require more surgery
  • Port or tube leakage may lead to mechanical failure
  • Regular follow-ups and adjustments required

Gastric Bypass vs Gastric Sleeve

The procedures involved in gastric bypass surgery are different than those performed in gastric sleeve surgery. Only a highly qualified bariatric surgeon can help you to make the decision about which procedure will be most beneficial for your specific condition.

Gastric Bypass Surgery for Specific Conditions

Gastric bypass surgery is a procedure in which a smaller stomach is created, separated from the rest of the stomach system. This surgery decreases the capacity of the stomach, creating a “full” feeling much more quickly, as the food fills a much smaller area. The remaining portion of the stomach will no longer hold food, but the normal blood vessels remain intact. This procedure is now performed laparoscopically, via smaller incisions, for a faster recovery time with less pain.

This surgery involves stapling the stomach and re-routing the intestinal tract, and as such, is a complex surgery. The changes to the digestive system alter how nutrients from food are absorbed by the body, and greatly limits the amount of food that can be consumed. For some patients, this will be the most effective surgical procedure, as it reduces the quantity of food that can be consumed and the number of calories your body is capable of absorbing. The end result can be fast, efficient weight loss. At West Medical, our team of surgeons and medical support personnel have extensive experience in this procedure, and are focused upon patient safety and health above all.

Gastric Sleeve Surgery for Gradual Weight Loss

Gastric sleeve surgery is a more recently developed form of bariatric surgery which has become one of the most commonly used procedures. This surgery is effective in resolving weight problems for people who have been unable to reduce the amount of excess weight through diet and exercise. The process involves changing the shape of the stomach, which decreases its capacity by nearly 85%, leading to curbed hunger. It results in a healthy, more gradual loss of excess weight.

One interesting facet of this procedure is that a hormone that creates the sensation of hunger is also reduced, and patients report that not only are they consuming far less food, their feelings of hunger are diminished – an important aspect of comfortable, consistent weight loss. After surgery, your diet must be carefully managed by choosing the correct foods in the proper quantities, as well as adding certain vitamin supplements. We work with you as a team throughout the entire process, and you will know how to manage your food intake correctly. Gastric sleeve surgery is performed laparoscopically, with small incisions, is less complex to perform than gastric bypass surgery, and has a lower risk of complications.

Which Surgery is Right for You?

A full evaluation of your condition and your overall health is the first step in determining the surgical procedure that will bring about the most positive results for you. Gastric bypass surgery has been proven to be effective for patients suffering from Type 2 diabetes, and has the benefit of a fast loss of excess weight. Type 2 diabetes patients who have a BMI over 35 (click here to view our BMI calculator), or those who are now pre-diabetic due to weight should discuss bariatric surgery with our team. Gastric bypass surgery can result in significant improvements in the condition and a much healthier life going forward.

Understanding Bariatric Surgery for an Informed Decision

Any surgical procedure carries risk, and it is important that a complete analysis of your health is undertaken when determining which surgical procedure will be most effective in your case. As obesity is a health risk in itself, and known to create other serious health problems, bariatric surgery can bring about a level of weight loss that has been impossible to reach through diet and exercise. At West Medical, we focus upon patient care at every step of treatment.
