Reviews Of Our Gastric Sleeve Surgery Results

Susan's Before & After

I tried pretty much every diet you can think of I've tried: motivation, Weight Watchers, Slimming World, all of them.

Happy, but wish I’d done it sooner. That’s my only regret, is that I didn’t think of doing it sooner, instead of struggling for 41 years with my weight.

Belfast Patients Gastric Sleeve FAQ

Weight loss after a sleeve is achieved in two ways.

  1. The volume of the stomach is dramatically reduced and more resistant to stretching. This means you feel full, with remarkably small amounts of food.
  2. The second mechanism of weight loss occurs through changes in a hormone called ghrelin. Ghrelin is normally produced in the fundus of the stomach (the large part removed during surgery) so that after surgery, levels of ghrelin fall dramatically. Given that ghrelin is a strong appetite stimulant, this means there is a marked loss of appetite – so you have no desire to eat. It’s likely that other appetite hormones are involved, which help to make you feel satisfied with much smaller volumes of food.

Another result of these hormonal changes is that diabetic control can start to improve even before you lose weight.

Aside from the two main mechanisms Another feature of the sleeve is that patients report changes in food preferences, with a reduced interest in sweets, high fat foods and alcoholic drinks, though whether these changes are sustained in the longer-term is not clear.

Short term weight loss

A patient’s weight loss is largely dependent on how much effort they put into the nutritional and exercise program.

Generally, the more you interact with the program, the more successful you will be. However, Auralia has never had a patient who simply hasn’t lost weight on our gastric sleeve program.

Whilst every person is different, we would expect our gastric sleeve patients to lose around 6-7 stone within the first 12 months. However, many of our patients have lost as much as 11 stone within this time. This is largely dependent on how compliant the patient is with the after-care program.

The gastric sleeve offers a dramatic weight loss relatively easily but unlike the gastric band, the long term weight loss isn’t as favoured.

Long term weight loss

The gastric sleeve gives you a dramatic weight loss early but the long term results show that the patients actually regain weight over time. This weight regain occurs due to a combination of stretching the gastric remnant (what’s left of the stomach after the surgery), poor dietary habits, and the return of appetite thanks to an increase in ghrelin levels.

Our Gastric Sleeve price starts from £9,500. At Auralia we can help you spread the cost of the surgery up to 36 monthly payments.

The three main risks to having a gastric sleeve fitted are:

Bleeding: This is the most common complication to occur. A blood transfusion
may be required with a re-operation, but it can be managed without further
surgery.
Leakage: This is the most dangerous complication to occur and it happens when
the contents of the stomach leak through the long-staple line. It can occur in the
first couple of days after the surgery. It is difficult to manage and may require the
patient to stay in the hospital longer.
Reflux: If you have a history of heartburn (reflux) then you won’t be able to opt for
the gastric sleeve. This is because your reflux will become worse after the
operation and you will be less likely to receive successful weight loss. Chronic
reflux can be a really serious problem in the lower gullet (oesophagus) which is
why this risk should not be taken lightly.

To qualify for a gastric sleeve, you must:
● Be between the ages of 25-50
● Have a BMI of 30 kg/m2 or higher
● Have no history of reflux/heartburn
● Have no history of previous weight loss procedures
● Be completely aware of the risks and benefits of the gastric sleeve

Advantages
● Excellent initial weight loss
● Does not require frequent clinic attendance for adjustments
● Reduces hunger hormones (unlike the gastric band)
● Preservation of normal passage of food through the stomach (unlike
gastric bypass)

Disadvantages
● Supplementation to avoid nutritional deficiencies
● Increased risk of reflux post-surgery
● Need for long-term vitamin and mineral
● Risk of leak and bleeding – sleeve is the riskiest procedure
● The tendency to weight regain in longer-term

There is no doubt that the sleeve can be an excellent choice for some patients and it has obvious advantages compared with the other surgical options. However, the risks are not trivial and there is a tendency to regain weight over time.

If you would like to consider a sleeve, the key thing to remember is that you must stick to the nutritional and physical activity guidelines with which you will be provided.

The mistake made my many sleeve patients is that they think it’s an easy option because it really takes away the appetite and so doesn’t seem to need the same commitment to lifestyle change. This is completely wrong. The reduction of appetite due to changes in ghrelin may not be permanent and if you start eating large quantities again, you may stretch the remaining portion of your stomach. If this happens weight re-gain is inevitable.

REMEMBER: For long-term success the sleeve requires the same commitment to permanent lifestyle change as any other surgical weight loss procedure.
