Mini Gastric Bypass Vs Sleeve

When you are thinking of getting a mini gastric bypass vs sleeve surgery, you are in front of two of the most popular procedures to fight obesity, limit weight regains, and enjoy a healthier life. At SIOS you can find a team of experts with over 16 years of experience in the field of obesity surgery, working according to the most demanding standards known to date. The first thing you should know is that both, mini gastric bypass and sleeve surgery, are restrictive and malabsorption procedures. This means that they work by reducing stomach size and, at the same time, limiting the amount of food and nutrients that can be absorbed by the body.

The main difference between the two procedures is that, while mini gastric bypass involves re-routing the small intestine to a smaller stomach pouch, sleeve surgery removes a large portion of the stomach, leaving a tube-like structure. When you decide to trust SIOS at the time of selecting the best option between a mini gastric bypass vs a sleeve surgery, you are trusting a responsible institution with over 16 years of experience in the field and all the tools needed to complete daily operations efficiently. Both procedures are effective in promoting weight loss and limiting weight regain, but mini gastric bypass has been shown to be more effective in the long term. This is probably because it leads to a greater reduction in stomach size and, as a result, to greater restriction of food intake.

If you need to know everything about mini gastric bypass vs sleeve surgery, do not hesitate to contact us; we will be glad to assist you and tell you everything you must know about this. You should consult with a team of experts to discuss which one is best for you, based on your individual needs and medical history.

Understanding Bariatric Obesity Surgery

Every person and their body are different.  What works for one person, may not work for another.  There are many different surgeries available but finding the right one for you that is safe and healthy is our utmost priority.  Your health and lifestyle as well as food and weight concerns need to be carefully considered in the decision of which obesity surgery is best for you.


Depending on your individual weight and health, you may be a candidate for weight loss surgery. In order to determine whether this weight loss option is for you, take these first steps:

Medicare-Funded Sleep Studies

A good night’s sleep is important for good health and also for maintaining a healthy weight. Obesity may contribute to sleep problems such as sleep apnea, and sleep problems can also contribute to obesity. SIOS offers sleep studies, fully funded by Medicare.
