Weight Loss Surgeries helps a person lose weight. Bariatric surgical procedures cause weight loss by restricting the amount of food intake, causing less absorption of calories, or by a combination of both gastric restriction and malabsorption. They either limit the amount of food you can intake or reduce your ability to absorb nutrition and in some cases both.
Weight loss surgeries work in variable and different ways. This includes restriction, which reduces the number of calories that one can consume by limiting the size of food that the stomach can hold. The other mode is malabsorption, which similarly minimizes the number of calories and consequent nutrients that the body can duly absorb. This is gained by shortening some parts of the intestine.
When this surgery is essential?
This procedure is done when the person has a high risk of potentially life-threatening health issues related to weight gain, such as the following:
Thus this procedure is not for everyone who is obese. And also screening processes are done to see if you are a suitable candidate for this surgery. Many weight loss surgeries are available to patients, but here are five main ones.
Types of weight loss surgeries
Duodenal Switch with Biliopancreatic Diversion
This procedure entails positioning the duodenal much more faraway and further along the ileum. The gall bladder is also removed. For example, this procedure results in very few calories being absorbed by the body from the food consumed. The stomach also secretes very little amounts of hunger-causing hormones, making the individual not feel hungry fast.
Weight Loss Surgeries
The duodenal switch also results in overall health progress by lowering the risk of some illnesses such as cancer after surgery. It can also treat some metabolic problems and even diabetes. Most doctors however avoid it, as it is tough and labouring to perform. It consumes more time and requires extensive follow up after surgery.
In biological and technical terms, the gastric band is referred to as laparoscopic adjustable gastric banding. The procedure entails the creation of a small pouch with the use of a gastric band well placed around the stomach. The pouch can be filled with very little amounts of food, limiting the amount of food that one can eat in order to fill it. In this case one feels full very fast, eliminating the need to consume great amounts of food.
Likewise, the gastric band is fastened after surgery by attaching it to a device placed under the skin, which is at the centre of the chest. In order to attain the desired results, the band is tightened severally. Also, this is done to prevent any need for anesthesia by injecting the device with some saltwater with the use of a needle through the skin.
Endoscopic Sleeve Gastroplasty
This procedure is generally considered safer than other bariatric surgeries. Symptoms such as pain and nausea can be observed for several days which can be easily fixed by pain and nausea medicines. For instance, most people fully recover in two to three days. Although this procedure is not a temporary one by it is a procedure that can be reversed. However, as this surgery is quite a new procedure, the long-term effects and risks are unknown.
In this procedure, an extensive part of the stomach is reduced, making it very small in comparison to the way it was prior to the surgery. Just as with the previous surgeries, one feels full very fast thus massively reducing the amount of food that one consumes.
For the most part, the new smaller stomach will secrete very small amounts of hormones that cause hunger, making you not feel hungry as fast as you used to be.
Gastric bypass is also known as Roux-en-y gastric bypass. As a result of the stomach is subdivided into two parts. Thus a small pouch is created at the top of the stomach with the use of surgical staples. Also, the rest of the stomach is bypassed by directly connecting the pouch to the small intestine. Similarly, it hugely reduces the amount of food needed for one to fill full. This ultimately ensures you consume less food, and thus you will absorb very few calories. Your body shall also absorb very few minerals.
Despite this, gastric bypass has a coupling weakness in that if one does not adhere to a very good and strict diet, it could cause dumping syndrome or even possible malnutrition.
Therefore indifferent to other types of surgeries, an intra-gastric balloon is quite temporary, as it is only left in the stomach for a maximum of six months. Your doctor fills the balloon with air and then places it into the stomach with the use of a very narrow tube, which goes down through the mouth. Such as the balloon is inflated upon reaching the stomach. It is also important to note that there exist two types of balloons namely the single and the dual balloon. Hence your choice depends on the size of the stomach plus the results you are looking to achieve.
The previous surgeries all have different advantages and disadvantages. For instance, the duodenal switch is the most useful, as it results in much more weight loss followed by the gastric sleeve and gastric bypass. Gastric balloon only results in 25-30% of the excess body weight after a year compared to duodenal switch, gastric sleeve, and gastric bypass where one loses around 70% of the surplus weight under the same time or duration. It is therefore vital to do some extensive research and doctor consultations before opting for any kind of the highlighted surgeries.
Risks and complication of bariatric surgery
BPD/DS risk factors include the following

- Adverse reaction to anesthesia

Pros and Cons of Biliopancreatic Diversion
Biliopancreatic diversion is very effective and successful when compared to other types of weight-loss surgeries. Also, it produces very long-term results extending to 18 to 24 months after the performance of the surgery. In fact, the surgery ensures that there is the maintenance of weight loss of around 80% of the excess weight even 10 years post-surgery. Such as this prevents any recurrence of future instances of obesity.
Enhanced quality of life after weight loss surgeries
The procedure improves the quality of life, and this can be due to improved mobility. Your fitness after weight loss also tops into a boosted self-esteem and a better sense of living. In addition to this, the surgery helps to alleviate and improve other health issues or illnesses often attributed to obesity. An example is a hypertension and diabetes. All these help to improve the quality of your life
Adjustability after weight loss surgeries
The biliopancreatic diversion procedure is adjustable. This means that there is a partial chance of reversing it through the performance of another surgery.
An excellent choice to other weight loss procedures
Biliopancreatic diversion is suitable especially if you have tried other weight loss methods but didn’t succeed. However, it could complete other weight loss methods such as working out.
Weight loss surgeries complications
Among all other weight-loss surgeries, biliopancreatic diversion is the most complicated. However, it is an open surgery, making it very delicate. It is for this reason that the procedure should be done by a professional. Due to its complexity, biliopancreatic diversion happens to be quite difficult. The main reason behind this is that it is performed as an open surgery instead of laparoscopically. Thus it has a death risk of 1 for every 200 surgeries done. Its complexity, therefore, suggests that the risk of death is very high compared to other surgeries.
Apart from causing death, you could be at risk of getting anemia due to a lack of iron. You can also get osteoporosis if you do not take supplements as directed by your doctor.
Extended recovery time
In short, the recovery time for biliopancreatic diversion ranges from 6 to 8 weeks. This could make you take substantial time off work to ensure that you recover properly.
Flatulence and high stool frequency
After a biliopancreatic diversion procedure, you will find yourself visiting the washrooms more than the ordinary person. Flatulence and further diarrhea can also happen spawning from the ingestion of very fatty foods.
How to keep weight off after weight loss surgeries?
