Roux en Y Gastric Bypass vs Laparoscopic Sleeve Gastrectomy.

First, I will explain a little bit about each one.

This picture here shows the normal gastrointestinal anatomy. 

When you eat food, you chew it and swallow and the food goes from your mouth, to your esophagus to your stomach.  From there it enters your small intestine.  The first of your intestine is called the duodenum, the middle is the jejunum, and the bottom is the ileum. After food passes through these 3 parts of your small intestines it passes into your large intestine (aka colon) and then is dispelled from your body.

            The size of your stomach is changed from the size of a football to the size of an egg. The small intestine is separated into 2 sections.  The lower portion of the small intestine is attached to the new small stomach pouch.  The upper part of the small intestine is reconnected to the lower part of the small intestine. When a small portion of the small intestine is “bypassed” there is a decrease in the way calories are absorbed. This surgery causes metabolic changes, which helps to improve diabetes and high cholesterol.

(sorry its sideways)

            The size and shape of your stomach is changed from a football to a long narrow sleeve or banana shape. About 70% of the stomach is then removed. The intestines are not re-routed.

Each surgery has their own risks and but the benefits of both are about the same. The amount of weight you may lose may be more with bypass, but it really is all-dependent on how well you follow the diet and exercise plan.  This surgery is a tool.  It is not a quick easy fix.  How much you lose is all on you and how much effort you put into it.

I chose the bypass surgery. Why did I choose this surgery?  #1 – I wanted to have the same surgery as my husband.  #2 – I wanted to have the greater chance of weight loss. #3 – You have a greater chance of “dumping syndrome” with bypass  - and honestly I felt I needed that negative reinforcement to keep me on track.

What is “dumping syndrome”? Dumping happens when you eat foods high in carbs (sugar), lactose, or fat.  Symptoms are weakness, cramping, nausea, vomiting, diarrhea, dizziness, and sweats.  Not everyone will get these symptoms and you are not to use this as a tool to lose weight either.  But once you experience it you don’t want to experience it again.  They did, however, say at the shared medical appointment that if you tend to eat a lot of sweets you should get gastric bypass, as this would really help you.  

Prior to my surgery I am doing my part by not eating as many sweets as I used to, so I don’t go into shock not having them.

After this shared appointment they said they would call the next day to schedule our surgery.  I will be seeing Dr. Trus. He told us he was booking 6-9 weeks out.

Check back tomorrow to find out when my surgery is scheduled for!
