A simple guide to bariatric (weight-loss) surgery. How it works. Bariatric (weight-loss) surgery is a medical procedure to help people lose weight. Losing weight lowers a person’s risk of other conditions and illnesses that are commonly associated with obesity. There are two ways in which bariatric surgery can aid weight loss.
How bariatric surgery helps someone lose weight
Whichever type of bariatric surgery is performed, there are two ways in which it works.
- Restriction – bariatric surgery physically limits how much food can be held in the stomach. As a result, this limits a person’s calorie intake.
- Malabsorption – bariatric surgery shortens or bypasses a section of the small intestine. As a result, the body can’t absorb as many calories or nutrients.
Common types of bariatric surgery
There are many different types of weight-loss surgery. These include:
- Lap band surgery
- Sleeve gastrectomy
- Needlescopic sleeve gastrectomy
Lap band weight-loss surgery
This surgery involves a band being placed around the stomach. The band creates a pouch at the top. With a gastric band in place, the stomach will be full more quickly. This means that a person won’t need to eat as much food before they feel full. The band is adjustable and is tightened to get the desired results.
The surgery is called ‘lap band surgery’ because it is carried out laparoscopically. Typically, your surgeon will make between 1 and 5 surgical incisions in your abdomen through which they will insert surgical instruments.
Sleeve gastrectomy weight-loss surgery
This surgery is where a large portion of a person’s stomach is removed. This makes what’s left of the stomach much smaller. As with lap band surgery, this means a person can’t eat as much and will feel fuller more quickly. This surgery is ideal for people who have obesity-related diseases like hypertension and Type 2 diabetes. Results show that patients can see a weight loss of between 50 and 70 percent of excess body weight following surgery.
Needlescopic sleeve gastrectomy weight-loss surgery
As its name suggests, a needlescopic sleeve gastrectomy is much less invasive when compared to a traditional sleeve gastrectomy. Oftentimes, when surgical procedures are made to be less invasive, their results are not as good. A needlescopic sleeve gastrectomy, however, is just as effective as a traditional sleeve gastrectomy. The benefits of this type of surgery are that the scarring is minimal. In fact, there will only be 4 minute scars, which is much better than the scarring from a traditional procedure.
How to choose a type of bariatric surgery
All bariatric surgery will help a person to lose significant amounts of weight but there are advantages and disadvantages to each type too.
Typically, there will be more weight loss following sleeve gastrectomy surgery and needlescopic sleeve gastrectomy surgery when compared to lap band surgery. However, there is a greater risk of serious complications with sleeve gastrectomies and needlescopic sleeve gastrectomies.
Unlike sleeve gastrectomies and needlescopic sleeve gastrectomies, lap bands can be removed. The procedure is, therefore, reversible and so if there are serious side effects or complications, the band can be taken out and the side effects eliminated. Of course, this means that the patient will no longer benefit from the lap band surgery. This article talks about whether a gastric band is right for you.
