Weight reduction surgery comes in a variety of shapes and sizes.

 


They're all performed using keyhole (laparoscopic) surgery under general anaesthesia (while you're asleep), but they operate in slightly different ways.


A surgeon performs keyhole surgery by making small cuts in the tummy and inserting a flexible viewing tube to see inside when performing the procedure.

The most common forms of weight-loss surgery

Gastric band


A gastric band is a band that wraps around the stomach and forms a small pouch at the tip.


Since it takes less calories to fill the pouch, you won't need to consume as much to feel satisfied.


The band is attached to a tiny unit that is inserted under the skin (usually near the middle of the chest). This allows the band to be tightened after surgery.

Approximately 4 to 6 weeks after surgery, the band will be tightened for the first time. This is accomplished by injecting a salt water solution into the device through the skin with a needle. This procedure generally does not necessitate the use of an anesthetic.


To get the band to the perfect tightness for you, tighten it a few times.


Gastric bypass 


Surgical staples are used to build a narrow pouch at the top of the stomach in a gastric bypass.


After that, the pouch is attached to your small intestine, bypassing the rest of your stomach.


This means you'll need less food to feel satisfied, and you'll consume less calories from your meals.

Sleeve gastrectomy


A sleeve gastrectomy involves removing a large portion of the stomach, resulting in a stomach that is much smaller than before.


This means you won't be able to eat as much as you could before surgery, and you'll be able to eat less.


Intra-gastric balloon

A soft balloon filled with air or salt water is inserted into your stomach through a thin tube that is passed down your throat (known as a gastroscopy).


This means you won't need or be able to consume as much food before feeling satisfied. However, this is just a temporary solution, and the balloon is normally left in for no more than 6 months.

Biliopancreatic diversion

The stomach pouch is attached further down the small intestine in a biliopancreatic diversion, which is similar to a gastric bypass.


As a result, you'll consume even less calories from your meal. However, it has more side effects than a gastric bypass and is thus less widely used.

Endolumena from primary obesity surgery

Obesity surgery for the first time endolumena is a modern method for reducing stomach size. An endoscope is a tube that is inserted into your stomach.


The endoscope is then passed through by a surgeon, who uses tiny instruments to bundle your stomach into folds in order to make it smaller.


Obesity surgery for the first time Since endolumena is not actually covered by the NHS, you would have to pay for it.

Which weight-loss surgery is the most effective?

Weight loss surgery of any kind will help you lose a lot of weight, but each has its own set of benefits and drawbacks.


Consider the following scenario:


A gastric bypass or sleeve gastrectomy typically results in faster weight loss than a gastric band, and more people prefer to achieve substantial weight loss with a gastric bypass or sleeve gastrectomy than with a gastric band.

the possibility of a major operation The risk of complications is higher with a gastric bypass or sleeve gastrectomy. But, since gastric bands are removable, the procedure may be reversed if it causes severe problems.

If you're considering weight loss surgery, discuss the various procedures with your surgeon to determine which is right for you.

Assessment before weight loss surgery

Before having weight loss surgery, you'll be referred to a specialist clinic for an evaluation to see if the procedure is right for you.


This could include looking at your:


Diet and eating habits are examined using blood tests, X-rays, and scans.

mental health – this includes questions about your plans for surgery and if you have any mental health problems, in order to determine whether you'll be able to handle the long-term lifestyle changes needed after weight loss surgery.

To further minimize the size of your liver, you might be recommended to follow a calorie-controlled diet in the weeks leading up to surgery. This will make surgery go more smoothly and safely.
