Which is the Safest Weight Loss Surgery?

Any kind of weight loss surgery will be a significant medical procedure, but there are differences in the risks. If you’re trying to decide which bariatric procedure is right for you, then one aspect you will need to consider is their safety. it.

Types of Bariatric Surgery

Three different types of bariatric procedure are available in London:


  • Gastric band surgery fits an inflatable band around your stomach to separate it into two sections. After the surgery you should feel satisfied after smaller meals because you will feel full when the small section above the band fills with food.

  • Gastric sleeve surgery removes part of the stomach so that you won’t be able to fit as much food into it. You should also feel less hungry because you won’t produce as much of the hormones that stimulate your appetite.

  • Gastric bypass surgery changes the route food takes through your digestive system. A small pouch will be created from the upper part of the stomach and connected to the lower part of your small intestine. The smaller stomach will feel full after smaller meals and food will bypass some of the intestine so that you don’t absorb as many calories.

How Invasive is the Procedure?

One important difference between the bariatric surgery procedures is in how invasive they are. Invasive surgeries require more incisions or more interventions inside the body.


  • Gastric band is least invasive as it simply involves fitting the band around the stomach

  • Gastric sleeve is moderately invasive as part of the stomach is removed

  • Gastric bypass is most invasive as it involves re-routing the digestive system

More invasive surgeries are riskier because there is a greater chance of heavy bleeding, infection and damage to the surrounding organs. The risks are still relatively low for bariatric procedures because they can usually be performed laparoscopically (using keyhole surgery techniques).


How Risky is the Procedure?

Weight loss surgery poses a number of different risks, from minor infections to serious allergic reactions to the anaesthetic.


  • Gastric band surgery has the lowest risks, with 1 in 20 patients experiencing some kind of complications and a mortality rate of 1 in 2000

  • Sleeve gastrectomy causes some complications for 1 in 20 patients and has a mortality rate of 1 in 500

  • Gastric bypass is the highest risk procedure, with 1 in 20 patients experiencing complications and a mortality rate of 1 in 200

Other Factors to Consider

Although it might seem obvious that you should choose the safest weight loss surgery, this isn’t the only factor that you need to consider. You should also think about the success rates and which procedure is most likely to help you to lose weight. The gastric bypass procedure is the riskiest option, but it also tends to produce the best results.

It is also important to weigh the risks of having the procedure against those of remaining overweight. The faster weight loss that is possible after a gastric bypass could be the safest choice if it will help with a medical condition that is putting you at risk. You will need to discuss the risks and benefits in detail with your doctor before making any decisions about your treatment.
