Obesity surgery and your options

Take time to choose the best treatment for you. Not every surgery is the same and not every person is the same.

There are many different surgeries available but finding the right one for you is our utmost priority.  We support you in choosing the most appropriate obesity surgery for you and your needs by providing enough information to you in order to make an educated decision.

All weight loss surgeries physically limit the amount of food intake. However, each type of surgery has positives and negatives. The considerations in choosing your obesity surgery include –


When choosing a surgeon, you should consider the type of operations they perform, and how many. Surgeons who perform operations routinely will be more experienced and some have more experience in particular types of obesity surgeries than other types. The surgeons at SIOS have extensive experience, adopt best surgical techniques, and provide exceptional quality of care.


All surgery comes with varying long and short-term risks, and obesity surgery is no different.  We talk you through all the pros and cons to find the right surgery for you.


Every person and their body are different.  What works for one person, may not work for another.  Your health and lifestyle as well as food and weight concerns need to be carefully considered in determining which obesity surgery will work for you.

Lap Band Surgery

The band is placed at the upper part of the stomach . It allows people to feel satisfied after eating only a small amount of food. As the size of the inlet to the stomach can be adjusted, food is slowed down on its journey, allowing you to eat small quantities of food over the same time that others will eat a large meal.


Sleeve (Tube) Gastrectomy

This operation has some resemblance to the old – fashioned so – called ‘stomach stapling’ procedures of the 1980s and 1990s (the vertical banded gastroplasty) and has probably replaced them worldwide. It involves removing the outer part of the stomach, thus significantly reducing the capacity to store food and generate hunger signals.


Gastric Bypass

Several forms of this procedure have been performed over the last three decades. It is based on an operation which has been used to treat stomach ulcers and cancers for more than a century, and the name is derived from the name of the French surgeon who first described the use of a small segment of small bowel to divert bile and acid away from the stomach and oesophagus.


Revision Surgery

All surgical procedures for obesity, both old and new, are designed to change how the person processes food. Although all of these procedures are designed to be permanent, in reality not all the effects of the surgery are permanent. Over time, parts of the stomach and oesophagus can stretch and sag, and patients can develop new conditions such as ulcers or reflux.
