The simplest approach to lose weight is to tell people to exercise and have a balanced diet. However, experts say that implementing these healthy changes to eating and exercise habits are not easy, especially for those who are overweight or obese. A person is considered obese if his body mass index is 40 or above.
There are a lot of people who are struggling with the bothersome areas of fat in their body. These areas do not really respond to the traditional non-surgical types of treatments like lifestyle and dietary changes. In this case, bariatric surgery can be the solution. Patients that have potentially life-threatening obesity resort to this type of surgery.
Bariatric Surgery: What is it?
This surgery spans a range of weight loss surgeries that could end one’s struggle with obesity by making permanent changes to the person’s anatomy. The procedures such as gastric banding, sleeve gastrectomy, and gastric banding have proven to be safe and effective in reducing a great amount of excess body fat.
Ways of Performing the Surgery
Every weight loss surgery works in one of three ways below:
A procedure like Vertical banded gastroplasty limits the amount of food intake of a person by surgically shrinking the size of the stomach.
Duodenal switch and biliopancreatic diversion are among the malabsorption procedures with a goal of inducing decreased absorption of calories from foods by shortening the amount and rerouting a portion of the small intestine.
A Combination of Both
Procedures in the given category take advantage of both malabsorption and restriction. In a combined procedure, the stomach is created and connected to the small intestine.
Open or Laparoscopic Surgery
A bariatric surgery could be performed with the use of open or laparoscopic surgery method that involve opening the abdomen by laparoscopy or the standard manner.
Traditionally, the bariatric method is an open procedure in which the surgeon creates a long incision to open the stomach. With this long incision, such an open procedure often results in longer stay in the hospital. Patients of this surgery often need week to heal before they can return to work and do physical activities. Moreover, a longer wound might put the patient at a risk of wound complications like hernias and infections.
The majority of bariatric procedures are performed through laparoscopic technique. The approach is more minimally invasive as it is performed through small abdominal incisions. On an average, 4-6 ports are made in the abdomen with the use of complex instruments like a small video camera that is being inserted to perform the said procedure.
Since laparoscopic surgery needs a smaller cut, it demands for shorter hospitals stay. With this, there will be lesser recovery time, as well as smaller scars. The majority of surgeons opt for this approach as it causes less tissue damage and has lesser risk of wound complications like hernias and infections which often happen after surgery.
