Frequently Asked Questions (FAQ)

We have listed here some of the more commonly asked questions from our patients about the Gastric Bypass procedure.

Q: How long does a gastric-bypass take?

This depends on the experience of the surgeon and if it is being done as an open or closed (keyhole) procedure. Open gastric bypass operations usually take 90-120 minutes, but laparoscopic bypasses may take up to twice as long to perform.

Q: How long will I be in hospital?

For open operations, most patients are discharged on the third or fourth post-operative day. Patients who have the laparoscopic procedure can go home on the second or third post-operative day.

Q: What are the benefits of gastric bypass?

For the seriously obese, the benefits of the gastric bypass procedure very much outweigh the risks. In general:

75% of patients are expected to lose 75 to 80% of their excess body weight, most of which is lost in the first two years following surgery.

Major improvements in risk factors for heart disease and cancer.

Around 70-80% of patients with hypertension will be off medication and cholesterol levels will fall.

Most type II diabetics will be cured.

There will be major improvements in a whole range of weight-associated conditions. These could include sleep apnoea, asthma, joint pain, arthritis, reflux, fatigue, shortness of breath.

Patients report less depression, improved self-esteem and confidence along with an overall increased sense of well-being.

Q: What are the risks of gastric bypass?

As with any surgery, there are operative and long-term complications and risks associated with gastric bypass, including:

•  Bleeding (haemorrhage).

•  Complications due to anesthesia and medications.

•  Infections.Pulmonary emboli (blood clots on the lung).

•  Deep vein thrombosis.

•  Dehiscence (wound breakdown).

•  Leaks from staple line.

•  Injury to the spleen.

•  Marginal ulcers.

However, in experienced hands the risks of the procedure nowadays are very small. Most published reports show that the overall mortality rate for gastric bypass surgery is less than 1%. It’s also important to note that not only does bypass result in reduced absorption of calories, it may also reduce absorption of important vitamins and minerals such as iron, vitamin B-12 and calcium. Deficiencies in these nutrients can lead to many problems.

Iron deficiency causes anemia and weakness and deficiencies in calcium can cause osteoporosis.

Lack of daily B-12 can lead to neurological problems. This is why patients undergoing gastric bypass are recommended to take a daily vitamin and mineral supplement. “

Dumping syndrome,” in which the consumption of sugar causes abdominal cramping and diarrhoea, can also occur.

Some people will also regain some weight in subsequent years.

A Word of Caution

Although there is no doubt that surgery can be both life-transforming and life-saving, the decision to go ahead with surgery is a serious one. Any general anaesthetic involves a measure of risk and individuals with serious degrees of obesity are at greater risk than their non-obese counterparts.

You should ensure that the surgeon you choose is experienced and that the full panoply of specialist advice is available at the hospital you choose. The choice of surgeon is crucial. This is not a procedure for the general surgeon. It should only be carried out by those who are specially trained in the surgery of the upper abdomen (upper GI surgeons).

The Need for Long-Term Follow Up

A final note of caution is to remember that surgery is not a cure for obesity. It is not a magic bullet and will not guarantee results without complete dedication by yourself and by your physician.

If you are going to be successful you will have to continue to work on the behaviours which are important for anyone attempting to lose weight, including physical activity, reducing portion sizes, avoiding energy-dense foods etc.

For this reason, you should ensure the hospital of your choice has available a structured, long-term behavioural and lifestyle programme, with nutritional support, which you should join immediately after surgery.
