Exercising, diet control, naturopathy, and weight loss supplements are known ways for weight reduction. When all these methods fail and one does not get his desired result then weight loss surgeries are an inevitable option left for extremely obese people.
People with diabetes, high blood pressure, cardiovascular disease have a high chance of stroke because of their excessive weight.
Nowadays, doctors are recommending these weight loss surgeries for quick and immediate relief from weight loss and its related diseases.
Most of the surgeries require a drastic lifestyle change and strict diet control and one who escapes it may face serious complications.
Here are different most common types of weight loss surgery.
Gastric Bypass Surgery
It is also known as Roux-en-Y gastric bypass.
It is the most popular method of the surgeries for weight loss and within six months one shall see drastic weight loss. In this surgery, the stomach is divided into two parts, the upper part is smaller and directly connects with the small intestine. This upper part is also known as a pouch. This pouch is less able to accommodate a large portion of food. This will limit food intake greatly. Because of the less space available to accommodate food in the stomach, the person feels early fullness and thus he eats less.
As food now bypasses the part of the stomach and the small intestine, the body absorbs fewer calories.
the National Institute of Diabetes and Digestive and Kidney Diseases research found that this surgery is relatively safe for weight loss. (1)
Vagal Blockade or vBloc
The vagus nerve runs from the brain to the stomach.
Its one of the main functionality is to tell stomach when it is full.
The vagal blockade is a pacemaker-like device which is implanted under the skin near the rib cage.
The device blocks the signals sent by the brain through the vagus nerve to the stomach to let you know you are hungry, so ultimately you do not feel that you are hungry and feel fuller and satisfied.
It is a similar method like gastric bypass in separating two sections of the stomach. It is laparoscopic surgery.
In this surgery, surgeons use an inflatable band to separate the upper part(smaller) of the stomach to the lower part(larger). And there is no “bypass” in this surgery.
Both the sections are connected through a small channel, which slows down the emptying of the upper stomach(smaller). Food needs to be well chewed and the person feels full after ½ to 1 cup of food. If you eat more then you will vomit right back.
In this surgery, part of the stomach is separated and removed from the body. The tubelike remaining smaller portion of the stomach is left. As now the size of the stomach becomes smaller, so it can’t hold much food.
Small size stomach produces less appetite-regulating hormone ghrelin, which may reduce the desire for food intake.
It is a restrictive weight loss surgery, which includes deflated balloon in the stomach (through the mouth). After placing in the stomach, it is filled with the saline solution, and ultimately you feel full and curb your hunger.
There is no surgery involved and no hospital stay required. It is the cheapest and least invasive weight loss surgery.
