Eligibility for weight loss surgery is assessed based on BMI (Body Mass Index) and the presence of other clinical conditions, called “comorbidities”. Surgery for obesity is considered an appropriate choice you if you have:
In certain circumstances, if you have a BMI lower than 30 you may be a candidate, if you e.g., have poorly controlled diabetes. Though medication and lifestyle changes are normally recommended.
You can calculate your BMI using our BMI calculator. You can also read more about weight loss surgery in our patient introduction guide.
If you are very young or above 65, weight loss surgery might not be the best option for you.
For underage patients (or pre-puberty patients); both you and your family will need to show that enough effort has been put to lose weight with non-surgical alternatives. We will also need proof that your family has visited obesity clinics in pediatric hospitals, or endocrinologists.
For patients aged over 65; the benefits of weight loss surgery will be reduced with age and might even be harmful for you. You should have realistic goals and expectations, and good health and clinical circumstances for weight loss surgery to be a viable option for you.
We recommend booking a consultation with our specialists to evaluate your options.
Your suitability for anesthetics will be assessed during consultation. If you are at high risk of a reaction to anesthetics, we will arrange a review and a consultation with our anesthetist. Depending on your situation, you might be asked to have a consultation with other specialists as well.
Your surgical suitability will be assessed during consultation, where we look at previous abdominal surgeries and how they impacted your abdomen. Previous weight loss surgeries are also considered.
We perform routine investigations and specific blood tests as well, to make sure that all parameters are in line with the norm pre- and post-surgery. In some cases, other tests (like ECG) are recommended.
A good number of people living with obesity suffers from depression and/or anxiety. To us, this can be attributed to the poor public perception and stigmas around obesity. Due to the ignorance of the public and some medical professionals, obesity is often blamed on the person. We understand that this is an oversimplification and misleads most people into wrong opinions around obesity and its causes. SMS is here to help you achieve your goals.
While we do not ask for all our patients to be reviewed by a psychologist, those with recognised conditions will be asked to provide a letter from their psychiatrist or to be reviewed and supported by their psychiatrist before weight loss surgery.
At SMS we do a thorough assessment of all your medical conditions and medications during your consultations.
Bringing a printed list of all medications you are taking and all allergies you have will ease the consultations.
Examples of medical morbidities and the medication adjustment:
Some patients will need to follow a strict diet for weight loss surgery to be a viable option. On average, a weight loss of 5 – 10 kilos is sufficient to proceed with the weight loss surgery.
The diet helps making weight loss surgery safer by softening the liver and allowing more space to operate. Following the diet is therefore essential.
We are now performing mostly sleeve gastrectomy (more than 90% of the procedures performed). Sleeve gastrectomy has proven to generally have better outcomes than gastric bands and gastric bypasses.
When assessing what type of weight loss surgery is best for you, we mainly look at three factors:
We will of course also take your situation and personal preferences into account and consult your choice.
It is our experience that gastric sleeves are most suitable for patients with no previous weight loss surgery, with a few exceptions for patients with:
Research suggests that gastric bypasses cause diabetes remission more than sleeve gastrectomies, but there is still no academic consensus on the topic.
Gastric bypass is not a suitable option for:
Gastric band surgery is not being performed at SMS. We believe the surgery to be outdated and, although it has fewer potential complications and is reversible, the risks of ruining the esophagus, stomach erosion or slipping are too high in the long term for this option to be preferred to other surgeries. Quality of life is also more heavily impacted by banding than the other options available.
