These procedures contribute to weight loss in the following ways;

  1. a) Malabsorption. The procedures modify the alimentary canal to cause an intentional malfunction in the absorption of nutrients and calories.
  2. b) Restriction. For those who have a big appetite, these procedures may limit the amount of food intake and accommodate by the alimentary canal.
  3. c) Diversion. Ater swallowing the food, some procedures seek to divert the food from the proper digestion and absorption pathway thus reducing the aggregate amount of absorbed food without reducing the food intake.

Let us delve into these procedures in detail.

1)    Gastric sleeve


This is a surgical weight loss procedure that involves resection of part of the stomach (mostly the greater curvature) to form a tube-like structure. Sleeve gastrectomy, therefore, acts in two main ways; reduction of the volume of the stomach this will give you early satiety due to signaling from the stretch receptors on the stomach wall and reduction of ghrelin(a hormone produced by the stomach lining that drives the appetite).


2)    Gastric bypass

Roux en Y bypass is what this procedure is known for. It is a surgery that helps you lose weight by changing how the stomach and small intestine handles the food intake. The small intestine is then cut, the distal end anastomosed with the bag created and the proximal end attached more distally to the small gut. This significantly reduces the amount of food ingested, It reduces the surface area for absorption and at the same time allow regular production and flow of bile and other enzymes.

3)    Duodenal Switch

In the duodenal switch, a sleeve gastrectomy is first done followed by an incision at the duodenum and the ileum. The distal tube (ileum)will be connected to the proximal end of the duodenum while the midsection tube in closed proximally while the distal end is connected to the ileum. This reduces the intestinal length and maintains bile flow.

4)    LAP band

The silicone band will be placed on the stomach to restrict the amount of food to be accommodated. The procedure is done laparoscopically and causes weight loss through restriction of food.

5)    Gastric balloon

Gastric balloon is placed into the stomach and once you are comfortable the procedure can begin. The balloon will occupy a large volume inside the stomach and thus be limiting the amount of food ingested hence bringing about weight loss.

6)    V bloc therapy

V bloc therapy is by far the safest weight loss surgery with a complication of only 3.7%. It works by blocking the vagus nerve which is responsible for sending hunger signals to the brain. This device empowers you to eat less, makes healthier choices and lose weight.
