Obesity cases in the country is increasing. A Centers for Disease Control and Prevention report has supported this claim. It confirms that at least one third of American adults in 2013 are obese. What are the common methods to address obesity?
Balanced diet and regular exercise are the most common methods to have a normal weight. In severe cases, doctors may recommend weight loss surgery to prevent complications. Heart disease, stroke and type 2 diabetes are the common complications of obesity.
Bariatric or weight loss surgery also helps improve the patient’s life quality. This is why weight loss surgeries are starting to rise in America. The American Society of Metabolic and Bariatric Surgery claimed that at least 200,000 patients have tried the operation in 2008.
Roux-en-Y gastric bypass and sleeve gastrectomy are the common weight loss surgeries. Another option is the laparoscopic adjustable gastric banding. Let’s have a deeper look at each one of these to assess their safety and effectiveness.
Types of Weight Loss Surgery
What is Roux-en-Y gastric bypass?
One of the most popular bariatric surgeries is the Roux-en-Y gastric bypass. Patients who undergo this surgery will have lower calorie intake. The operation will also restrict the patient’s capacity to trigger nutrients malabsorption.
How do surgeons perform the Roux-en-Y gastric bypass? The focus of the surgery to have a small pouch at the stomach’s upper part. The aim is for the pouch to be the only one to receive food. This in turn will limit the food and drink intake of the patient.
There is nothing to worry about this weight loss surgery. This is because the stomach will continue to produce digestive juices. Nutrient malabsorption will also take place as the foods will not go through a certain part of the small intestine.
What is sleeve gastrectomy?
Another popular weight loss surgery for obese patients in America is sleeve gastrectomy. It is similar in a way with Roux-en-Y gastric bypass as it lessens the stomach’s capacity to hold food. Let’s have a closer look at how doctors perform this operation.
Sleeve gastrectomy is a safe procedure. Among its results is to cut the appetite of an obese patient. But how will we get to this outcome?
Surgeons will cut out a stomach part to lessen its food-holding capacity. The doctors will then form the remaining stomach part into a tube-shaped structure. This will then decrease the production of ghrelin, the hormone that regulates our appetite.
What is laparoscopic adjustable gastric banding?
How do surgeons perform the laparoscopic adjustable gastric banding? The procedure is different from the first two methods. This weight loss surgery focuses on the addition of an inflatable balloon to the top of the stomach. The balloon has a super small opening to limit the food volume that is going to the stomach.
Patients who undergo this surgery will also have a port under their abdomen’s skin. The port is import to adjust the balloon size. Among its end result is to cut the food-holding capacity of the stomach. Unlike the first method, gastric banding does not help with nutrient malabsorption.
What is biliopancreatic diversion with a duodenal switch?
Another effective weight loss surgery is the biliopancreatic diversion with duodenal switch. This method is somewhat similar to sleeve gastrectomy. How do surgeons perform the operation?
The weight loss surgery starts with the cutting of a big portion of the stomach. The operation leaves the valve in the stomach to still transfer food and fluids to the small intestine. The surgeon will then form a duodenal switch. The switch will be present after the surgeon closes the small intestine’s middle part and connects the end area to the duodenum.
The surgery also aims for the patient to have a biliopancreatic diversion. The diversion will be there once the cut off part of the stomach is connected to the small intestine’s end part. The reattached part will help move the pancreatic digestive enzymes and bile to the intestine.
Effective weight loss is one of the top benefit of this operation. This is because it promotes nutrient malabsorption like the Roux-en-Y gastric bypass.
What is vBloc Therapy?
This weight loss surgery is a little bit different from the other methods. The surgery does not remove any part of the digestive tract. It focuses on adding a device near the rib cage.
This operation is unique. It does not limit the food holding capacity of the stomach but restricts the vagal nerve’s capacity to send hunger stimulants to the brain. End results will then be appetite loss and fast feeling of being full.
Effectiveness of Weight Loss Surgery
It is about time to assess the effectiveness of weight loss surgery. Many people are still questioning their effectiveness in comparison to other non-surgical ways. The effectiveness of weight loss surgery is seen in a study from the BMJ. It reports that non-surgical techniques are less effective than bariatric surgery.
Other clinical studies support the claim of the BNMJ report. These research found a low association of stroke and heart attack with weight loss surgery. Moreover, these studies promote weight loss surgery since it boosts sex drive in obese people.
Other Notes on Weight Loss Surgery
Bariatric surgery is truly effective, safe and beneficial to obese patients. The benefits of this operation will be obtained through constant communication and follow-up checkups with a doctor.
Medical experts also recommend obese patients to first explore the different options available to them before deciding on having the surgery. This will ensure that they choose the operation that will provide them with the best results. They can also check out some tools like the Ethicon Bariatric Surgery Comparison Tool before going through the operation. This tool is helpful as it provides the outcomes of the different surgeries in patients that have the same conditions. It is also recommended to physicians and surgeons as it will help increase their knowledge of the other benefits as well as the risks associated with the different weight loss surgeries before performing them to their patients.
