Weight loss surgery as a final resort can fruitfully help severely overweight or obese people lose excess weight. There are a number of diverse types of weight loss surgeries to prefer to. Discuss with your health care provider to discuss whether or not you make a good candidate for weight loss surgery, which course of action would work best for you and whether natural options like Slimirex might be safer and more effective.

How Does Weight Loss Surgery Work?

There are 02 basic types of weight loss surgery that are currently used for weight lessening. Restrictive procedures work by decreasing food intake. Malabsorptive procedures, then again, alter digestion, and cause food to be badly digested and partly absorbed so that it is eliminated in the stool.

Restrictive Procedures:

Restrictive weight loss surgery works by altering the size of the stomach, to decrease the amount of food that can be consumed at one time. It does not, yet, mess about the normal absorption or digestion of food. Unlike old weight loss surgery,  arestrictive weight loss surgery involves the creation of a small stomach pouch in the upper portion of the stomach. The capability of this pouch is about one half to one ounce. Then the pouch connects to the rest of the stomach through an outlet known as a "stoma." The abridged stomach capacity permits the patient to feel fuller with less food, and by decreasing overall food intake, the patient can reach sustained weight loss plan in a  special method . The achievement of this weight loss surgery eventually depends upon the ability of the patient to alter his or her eating habits. After surgery, it is probable that the patient will only be able to consume a maximum of one half cup full of food at each sitting. Fulfillment with these requirements is necessary to keep away from stretching the pouch and defeating the purpose of the surgery.

* Vertical Banded Gastroplasty: This is restrictive weight loss surgery in which the upper stomach near the esophagus is stapled perpendicularly for about 2 - 1/2 inches to create a smaller stomach pouch. The outlet or stoma that attachs to the rest of the stomach is restricted by a band or ring that slows the emptying of the food and permits the patient to feel fuller with less food consumption. After ten years, studies explain that patients can maintain at least 50% of targeted excess weight loss.

Advantages

The primary advantage of this restrictive procedure is that a reduced amount of well-chewed food enters and passes through the digestive tract in the usual order. That allows the nutrients and vitamins (as well as the calories) to be fully absorbed into the body.
After 10 years, studies show that patients can maintain 50% of targeted excess weight loss.

Risks

Postoperatively, stapling of the stomach carries with it the risk of staple-line disruption that can result in leakage and/or serious infection. This may require prolonged hospitalization with antibiotic treatment and/or additional operations.

Staple-line disruption may also, in the long-term, lead to weight gain. For these reasons, some surgeons divide the staple-line wall of the pouch from the rest of the stomach to reduce the risk of long-term staple-line disruption.

The band or ring applied may lead to complications of obstruction or perforation, requiring surgical intervention.

Characteristically, these procedures, while creating a sense of fullness, do not provide the necessary feeling of satisfaction that one has had "enough" to eat.

Because restrictive procedures rely solely on a small stomach pouch to reduce food intake, there is the risk of the pouch stretching or of the restricting band or ring at the pouch outlet breaking or migrating, thus allowing patients to eat too much.

Around 40% of patients undergoing these procedures have lost less than half their excess body weight.

As is the case with all weight loss surgeries, readmission to a hospital may be required for fluid replacement or nutritional support if there is excessive vomiting and adequate food intake cannot be maintained.

* Laparoscopic Adjustable Gastric Banding: This restrictive weight loss surgery, also identified stomach banding, makes use of  a band to divide the stomach into 02 portions. The band is placed around the higher most part of the stomach, dividing the stomach into a small upper portion and a bigger lower portion. Because food is keeping pace, most patients feel occupied faster. Food digestion happens through the normal digestive progression. This surgery can be reversed as the band can easily be removed from the stomach. As with other weight loss surgeries, the success of this procedure is based on the compliance of the patient with a restricted diet and the development of an exercise system.

Advantages

This method is:
1. less invasive surgical intervention available for the treatment of morbid obesity, as no alterations are made to the anatomy of the stomach or intestines.
2. the only method which enables a perfect calibration of the stoma diameter and pouch size (small part of the stomach which remains above the band).
3. the only method where the width of the stoma can be modified postoperatively without further surgery.
4. the only totally reversable method in obesity surgery, in which the anatomy of the stomach is entirely restored to its original form, after the band is removed.

About weightloss

Average weightloss obtained with the laparoscopic adjustable gastric band is comparable to traditional surgical methods.
The percentages listed below represent average excess body weight loss over a period of 5 years.
3 months: 20% (excess body weight loss)
6 months: 20-40%
1 year: 58%
4 years: 65%.

It is of course essential that you comply with:

-  medical advices
-  dietary instructions
-  follow-up controls
-  exercising

* Gastric Sleeve Resection: This is a relatively new approach. It is the first component of the duodenal switch operation and involves removing the lateral 2/3rds of the stomach with a stapling device. It can be done laparoscopically ( keyhole surgery) but is not reversible. It basically leaves a stomach tube instead of a stomach sack.

This is the first component of a Biliopancreatic Diversion / Duodenal Switch where the stomach is reduced in size by removing the lateral 2/3rds leaving the stomach in the shape of a tube. Sometimes it is offered to patients as part of a two stage Bypass operation particularly if they are super obese ( BMI>60) because it allows good weight loss until the patient gets down to a safe weight and the more radical bypass can then be offered laparoscopically when they are at a safer weight. The residual stomach capacity is about 200mls so a generous entree should be possible.

Issues with Tube gastrectomy

1. Stomach tube may stretch up over time leading to late weight regain. The extent of this is currently unknown

2. The amount of weight reduction is in the region of 40-60% of excess wt lost over the 
first 1-2 years.

3. There is no malabsorbtion to nutrients

4. If weight is regained the second stage of Duodenal Switch or Gastric Bypass can be added laparoscopically.
 

What are the risks associated with gastric sleeve resection?

The risk of postoperative complications average out between 3-5%. This includes infections, pneumonia or bleeding. Severely overweight patients run a higher risk of incurring operative complications. The risk of mortality is, according to literature, below 0.3%.
It is also possible to regain weight after some time, because snacks and high calorie food could make the band ineffective.
The main goal is to make radical changes in your lifestyle after gastric sleeve resection. You must learn to have five meals a day and no snacks in between. Also, high calorie drinks such as coca cola, ice-tea or any other soft drinks must be avoided.
Possible risks specific to gastric sleeve resection and their frequency according to statistical data found in the literature and in our series:
- Stomach mucus irritation and swelling due to vomiting or antiinflammatory drug use
- Wound infection
- Blood loss after surgery
