Description

The aims are twofold; firstly to assess feasibility of recruitment to a randomised control trial (RCT) comparing two band management strategies (intention to maintain band inflation versus band deflation); and secondly, to explore women’s physical and psychological experiences of pregnancy following LAGB using motivational theory as a framework.

Layman's description

Being overweight is a growing issue which can create problems in pregnancy for mother and baby. Weight-loss surgery is becoming more common, particularly for young women.

Gastric banding is one type of weight-loss surgery in which a band with a fluid-filled balloon is placed around the stomach using keyhole surgery. The band splits the stomach into two parts. The space taken up by the inflated band slows food passing from the upper to the lower part; causing food to collect in the upper part, resulting in a feeling of fullness more quickly. This reduces the amount of food that can be eaten and results in weight-loss. Once the band is in place, the balloon can be adjusted to control the amount of food passing from the upper to the lower part and therefore the amount of food eaten.

More often now women who have a gastric band in place are becoming pregnant. At the moment we have no information to guide doctors on how best to deal with the gastric band in pregnancy. Keeping the band inflated may reduce the food women eat and the weight they gain in pregnancy. It may also make other problems such as high blood pressure and diabetes, (which occur more often when a person is overweight), less likely to happen. However, keeping the band inflated may affect the growth of the baby, so it may be better to deflate the gastric band early in pregnancy. More studies are needed to see how inflating or deflating the gastric band in pregnancy affects the mother and her baby.

Women who are overweight are more likely to suffer low mood and have a poor self- image before weight-loss surgery. However, some studies show that women have lower risk of depression and a better image of themselves after weight-loss surgery. What hasn’t been looked at is how pregnancy may affect the wellbeing and mood of women who have a gastric band. We are also unsure what issues would be most important to women if they had to make a decision on whether they keep their band inflated or deflated in early pregnancy. We plan to ask women who are pregnant after gastric band surgery about their experiences of pregnancy and what issues (e.g. risk of problems for mother or baby) would affect their views on whether the band should be inflated or deflated in pregnancy. We also plan to find out whether women would have liked to take part in a study comparing inflation with deflation of the band in pregnancy, and what could have made them taking part in such a study more likely. This will help us plan a large study to answer the main question: inflate or deflate the band in pregnancy?
