There are numerous methods that can be used in losing weight by New York residents. The most widely used are dietary changes and engagement in physical exercise. While these are effective and safe in most people, they tend to take quite long. They may not be appropriate for a person that intends to shed off extra pounds for a special occasion within a short period of time. Bariatric weight loss surgery is an option in this case.
Bariatric operations are also called restrictive surgeries. This term is sometimes used because of the reduction in stomach capacity that is created by the surgeries. The amount of food that can be held by the stomach in any one sitting is considerably reduced and this translates to reduced absorption of nutrients. The few calories obtained from the food are mainly used for the provision of energy with very little going to storage as fat.
The main types of bariatric surgeries that are performed are sleeve gastrectomy and gastric banding. Although the two are fundamentally different, the end results is largely the same. They both cause a significant reduction in the functional size of the stomach which in turn reduces the amount of food eaten. One of the major differences is that banding can be reversed while sleeve gastrectomy is permanent and cannot be reversed.
Gastric banding is usually performed using a laparoscope. It involves the placement of a band (silicon-based) to the upper stomach region so as to cause compression. The lower portion is converted into a small pouch that can hold an ounce of food or less. Laparoscopy makes it possible to conduct the operation through small incisions which leads to fewer complications and less prominent scars.
The silicon band is connected to a long plastic tube that can be easily accessed from an area under the skin. By injecting and withdrawing saline or sterile water into the tube, the pressure that is exerted by the band can be regulated. Injecting the saline into the tube increases the pressure which effectively reduces the size of the stomach further. The reverse happens when the saline is withdrawn.
This surgery is fairly safe but one should be aware of possible risks that exist. Nausea, vomiting, infections and aversion to food are among the most commonly encountered. Releasing the compression slightly by drawing a bit of saline from the tube helps relieve a number of these symptoms. The compression can then be restored slowly over tome to achieve the original stomach size.
Sleeve gastrectomy involves surgical resection of the stomach with the aim of reducing its size. After the operation only 20 to 25% is left. The structure that is left is more tubular which reduces the transit time of food. Reduced absorption of nutrients, therefore, occurs due to two main reasons: the increased transit time and the reduced intake of food. Side effects here are similar to those of banding.
Recovering from the operation takes just a few weeks. One can resume their regular diet after about two weeks. The results vary from one person to another due to a number of factors. These include the surgical technique used, the magnitude of the problem, complications and so on. To increase the chances of success, you will be well advised to adopt a change in lifestyle as well.
