Types of weight loss surgery: Educating yourself about the same and more
If you are presently mulling a weight loss surgery then the first thing that you should do is educate yourself about the options made available for you. Now, let us clarify from the very beginning that weight loss surgeries are performed with the help of minimally invasive techniques today. They are malabsorptive or restrictive in nature whereby the surgeon leaves you with a smaller stomach so that you absorb fewer nutrients at the first place.
In certain cases the surgeon implants an electrical device which facilitates the weight loss process by interrupting the nerve signals between the brain and the stomach. This one is the newest technique employed for weight loss today.
Causes: Who qualify for these weight loss surgeries?
There are several types of weight loss surgery performed today (as has already been mentioned above). Which surgery should you opt for? This question can best be answered by your surgeon. The types of surgeries thus chosen by different people differ with weight loss goals, suitability and other factors.
People having Body Mass Index (BMI) of 40 or more generally qualify for this treatment – which means one has to be around 100 pounds overweight – in case of a man and 80 pounds overweight in case of a woman.
People who have lower BMI but are still grappling with problems like obesity, type 2 diabetes, heart disease and high cholestrol may seek the merits of a weight loss surgery as well.
However, a credentialed surgeon will only advise a surgery once he is sure that other means like exercise and diet have failed.
Treatment: What the different procedures entail
Adjustable Gastric Banding is a common type of bariatric surgery where the surgeon ties your stomach with an adjustable band to squeeze it into an upper and a lower section. There’s a small channel connecting the two portions. The purpose of the small channel is to slow down the emptying of the upper (smaller) part.
After this surgery, patients aren’t able to have more than one cup of food.
Sleeve Gastrectomy is another common type of surgery which entails the surgeon eliminating around 75% of the stomach only to leave a sleeve or narrow tube behind.
Gastric bypass combines the malabsorptive and restrictive weight loss techniques, whereby the surgeon divides the stomach into two sections- totally sealing off both the parts from each other. The upper part of the stomach is then connected with the lower part of the small intestine.
The least invasive of the weight loss treatments discussed here the Maestro Rechargeable System. The device serves more like a pacemaker sending electrical pulses to a nerve positioned between the brain and the stomach. This is the vagus nerve which informs the brain when the stomach is full. The abdomen holds the device which is programmed to work with the nerve during waking hours.
Risks and results
The patients should have a clear idea about the risks of each of the treatmewnt options before stepping inside the clinic.
The adjustable gastric baning surgery has a faster recovery period than gastric bypass and is safer as well. However, risks include vomiting after eating too much, the leak and the misplacement of the band.
Additionally the weight loss process is slower.
Sleeve gastrectomy is irreversible and associated with short-term risks like infection, leak and formation of blood clots.
Though gastric bypass is associated with immediate benefits like faster weight loss and gradual recuperation from obesity-related diseases like high blood pressure, diabetes and arthiritis, there are certain risks to be taken into account. The loss of nutrients from your body can result in anemia and osteoporosis.
