Gastric bypass surgery involves creating a small stomach pouch and constructing a 'bypass' of some of the small intestine.
Gastric banding involves placing a silicone band around the uppermost part of your stomach to restrict the passage of food.
Sleeve gastrectomy involves removing a sleeve of the stomach leaving behind a banana shaped and sized stomach.
How successful is bariatric surgery?
Studies show that bariatric surgery can effectively improve, resolve or even ‘cure’ many of the associated conditions. You can expect:
- Improvement in or complete resolution of type 2 diabetes, hypertension, and sleep apnoea
- On average a 60% reduction of your excess weight
What are the complications and risks associated with bariatric surgery?
As with any surgery, there may be immediate and long-term complications and risks.
Discuss the benefits and risks with your Brighton Bariatric healthcare team.
Possible risks can include, but are not limited to:
- Complications due to anaesthesia and medications
- Deep vein thrombosis and pulmonary embolism
- Wound infection
- Leaks from staple lines
- Breathing problems
- Spleen injury
- Stenosis (narrowing of a passage)
In general, the operative complications associated with Roux-en-Y gastric bypass in the hands of a skilled surgeon is approximately 5%, and the operative mortality (death) is approximately 0.5%. For gastric banding and sleeve gastrectomy, the operative morbidity is approximately 5% and operative mortality is approximately 0.1%.
What are the possible side effects of bariatric surgery?
Side effects include:
- Vomiting, Diarrhoea, Bloating, Increased gas
- Nutritional deficiencies
- Need to avoid pregnancy temporarily
- Excessive sweating
What impact do my medical conditions have on the decision for bariatric surgery?
Medical problems, such as serious heart or lung problems, can increase the risk of any surgery. On the other hand, many serious medical conditions may improve or resolve after successful bariatric surgery. The risks of the surgery are weighed against the benefits you are likely to get from losing weight and improving your health profile. A full discussion and thorough medical evaluation will be carried out by your Brighton Bariatric surgeon and anaesthetist. If it is found during your initial consultation or following further evaluation that Bariatric Surgery is not right or appropriate for you for whatever medical or psychological reason we will discuss the options available to you either privately or via the NHS and your GP.
How long do I have to stay in the hospital?
It varies from person to person. Generally, the hospital stay (including the day of surgery) can be one to two days for a gastric band and two to three days for a laparoscopic gastric bypass and sleeve gastrectomy.
Can I get pregnant after bariatric surgery?
Most doctors recommend that women of childbearing age wait at least one year after the surgery before a pregnancy. Approximately one year postoperatively, your body should be fairly stable (from a weight and nutrition standpoint), and you should be able to carry a normally nourished foetus.
What about postoperative pain and discomfort?
Many people think bariatric surgery will be followed by a long and painful recovery period. However, most patients report experiencing only discomfort and soreness rather than pain. Recovery does, however, vary from patient to patient.
Almost all patients have keyhole laparoscopic surgery which, compared to open surgery, offers:
- A shorter hospital stay
- Faster recovery
- Less pain
- Less abdominal trauma
- Less scarring
