Obesity & Weight Loss Surgery

This very much depends on how your assessments go with our team. Some patients have significant problems that need to be dealt with first before we can go ahead with surgery. This may take repeat visits to us over a number of months as well as other investigations (such as into sleep disorders).

The amount of weight lost after surgery depends on the type of operation, but more importantly on changing your lifestyle and eating habits. Weight loss requires reducing your food intake and increasing exercise. If you don’t stick to this then you will not lose enough weight and may even to put it back on again. It is important to be realistic about weight loss. The primary aim of weight loss surgery is to solve the problems caused by your obesity and not to get you to your ideal weight. If you lose more than 50% of your extra (excess) weight and it doesn’t come back on again this will be classed as a success. In general weight loss is faster after gastric bypass and sleeve gastrectomy surgery with most of the weight lost within the first 6 months and stabilising after 12-18 months. Gastric band surgery causes a slower more gradual but steady weight loss.

After significant weight loss there will inevitably be some areas where the skin starts to sag (around the tummy, under the arms and thighs, and breasts). How bad this is depends on how much weight you lose, your age and skin tone (generally younger patients have a better skin tone). How much this effects you is personal with some patients not being bothered by it, and others finding it very difficult to cope with. Occasionally the skin folds can become infected or sore if they are difficult to keep clean and dry. The only way to effectively deal with loose skin is with plastic surgery although this is not routinely funded within the NHS unless there are exceptional circumstances. You will need to discuss this with your GP if you feel that it becomes a major problem.

Some people notice that they lose some hair or that it becomes thinner after weight loss. This can be distressing, but it is only temporary and usually gets better after a few months. Many patients describe developing very dry skin when losing weight rapidly. You can combat this by drinking plenty of fluids, taking your multivitamin and applying a good moisturising cream daily.

This depends on your type of work, but generally gastric band patients have 1-2 weeks off work and the gastric bypass or sleeve gastrectomy patients have longer (up to 6 weeks)

The National Bariatric Surgery Registry, 2010 reported that the average excess weight patients lost after 1 year was approximately 40% for gastric banding, 50% for sleeve gastrectomy and 70% for gastric bypass. The amount of weight lost after surgery however varies greatly from person to person. Ultimately, it is down to the changes you make to your lifestyle and eating habits. Weight loss requires reducing your food intake and increasing exercise. If you don’t stick to this then you will not lose enough weight and may even to put it back on again.
