Mini Gastric Bypass main advantages are that it has been shown to give the best weight loss long term, with approximately 80% of patients successfully losing a substantial amount of weight.
It usually allows a wide range in the types of foods patients can tolerate, and therefore usually allows a very good quality of life. It has been shown to have a very high resolution of Type 2 diabetes, High blood pressure and sleep apnoea. These effects are often seen sooner than in other procedures such as a sleeve gastrectomy or Lap band surgery. It has a lower risk profile than Roux en Y gastric bypass as it has only one bowel join (anastomosis) and there is less long term problems with abdominal pain and bowel obstructions than Roux en Y gastric bypass surgery

Mini Gastric bypass can be more successful weight loss in patients who tend to eat sweet snacks than the sleeve or Lap band surgery. If patients eat sugary foods after gastric bypass surgery then these are rapidly absorbed and cause rebound low blood sugar (dumping syndrome).This often makes patients feel unwell by feeling faint and lightheaded. It will “smack your hand if you’re naughty” is what one of patients’ description. This can often help patients avoid sweet thingsin significantquantities; a small amount is usually tolerated but a large amount e.g. a whole snickers bar will lead to unpleasant side effects.

The Mini Gastric Bypass may be well suited to patients who have been previously unsuccessful with other forms of weight loss surgery, e.g. Lap band or Sleeve gastrectomy. There is increasing studies from around the world that has shown it to have the most success when used in revisionsurgery with approximately 70 % of patients achieving substantial weight loss.

The thing to remember is that because you will be eating less and/or your body will be absorbing less, it is important to focus on good quality nutritious meals to ensure your body gets all the nutrients it needs.

Regular follow up with our team, as well as the dieticianis very important. We ask that you take a multivitamin at least once but sometimes twice a day. Some patients may require extra vitamins
e.g. B12, Vitamin D, Folate, Iron and Calcium if they are low in these essential vitamins.

We check all patients essential vitamin levels preoperatively, and recommend regular pathology testing of vitamin levels every 6-12 months post operatively. Sometimes more frequently if patients are low in any essential vitamins. These can be arranged with our clinicians or through your GP if you would prefer. Whilst it is still low risk, approximately 5% of patients, may develop low levels of essential vitamins if they don’t take the multivitamin because it can lead to serious complications if not treated it is important to take the multivitamins and have the regular blood tests.
We recommend at least Annual blood tests of FBC, ELFT, Vitamin B12, Folate, Iron studies and Vitamin D.If you have any questions about this please contact the team

Like all surgery there are risks involved with this operation.
The potential risks and complications with a single anastomosis gastric bypass include, but are not limited to, leak from the anastomosis. A leak in the join which can happen in 1% of patients can be extremely serious, and can have potentially life threatening complications. It may require further surgery and a longer stay in hospital bleeding, damage to the surrounding structures including the liver, spleen, stomach and oesophagus, blood clots in the leg veins or lungs, hernia formation and wound infection, ulcer development at the bowel join, gall stones which can occur in approximately 20% of patients (this may require another surgery to remove the gall bladder).
Dumping syndrome leading to diarrhea and nausea. Vitamin and nutrient deficiencies can occur in 5% of patients who don’t take suitable multivitamin/mineral supplements. Hence the need for annual blood tests to avoid complications

Very occasionally 1:500 patients can, lose too much weight, have vitamin problems, have excessive dumping syndrome and need a reversal. Gastric Bypass is considered permanent, but it can be reversed if required.Unfortunately patients who have a reversal usually have rapid weight gain.

It’s possible to not lose enough weight or to regain weight after weight-loss surgery. This weight gain can happen if you don’t follow the recommended lifestyle changes. If you frequently snack on high-calorie foods, for instance, you may have inadequate weight loss. To help avoid regaining weight, you must make permanent healthy changes in your diet and get regular physical activity and exercise.

It’s important to keep all of your scheduled follow-up appointments after weight-loss surgery so that your doctor can monitor your progress.
