Sleeve Gastrectomy vs Gastric Bypass

When choosing a weight loss surgery there are several questions you may ask. The most prevalent that most people ask themselves is which type of procedure should I get?

The two most popular weight loss surgery procedures are the gastric sleeve and gastric bypass. Most doctors who are not recommending lapband, recommend one of this two types of weight loss surgery.

The gastric sleeve is considered the safest of the two surgeries, but you will not lose as much weight with the gastric sleeve or vertical sleeve surgery as you will with the gastric bypass or the Roux-en-Y bypass surgery. There are also other items to consider. While patients normally lose more with with the gastric bypass, there are also more complications associated with this surgery are well as longer recovery times.

The gastric sleeve surgery involves removing a portion of the stomach thus making it smaller and it restricts food intake. Since the stomach stays pretty much in tact, then the chances of the patient not getting enough nutrients is reduced.

The gastric bypass procedure also restricts the amount of food intake a patient can consume, but it also creates a malabsorption effect where some of the nutrients are bypassed( thus the name gastric bypass) the stomach area. This can increase the likely hood that a patient will not receive the proper nutrients and can cause complications.
