Gastric Bypass Surgery

Gastric Bypass Surgery

Advanced Cosmetic Surgery offer Gastric Bypass surgery for people suffering with obesity.

Gastric Bypass surgery combines the surgical reduction in the size of the stomach and also bypassing part of the small intestine.

The reduction in the size of the stomach means thats less food can be consumed and the bypassing of part of the small intestine results in less food being absorbed into the body.

After the Gastric Bypass operation, weight can be lost by three mechanisms which work in combination with each other:

  • The size of the stomach is reduced which minimises the size of meals that can be consumed. People feel less hungry after a much smaller meal.

  • The stomach usually empties into the top of the small intestine where digestive enzymes start to digest the food - After the Gastric Bypass, the food bypasses the top part of the intestine to a place further down, reducing the enzyme activity and thus reducing the number of calories absorbed.

  • After the Gastric Bypass when a person eats too much sugar, the body is 'tricked' by the sugar into releasing too much of a hormone called insulin. This reduces blood sugar levels, making the person feel light-headed and queasy. This leads to a genuine distaste for the wrong types of food and acts as a built-in mechanism to prevent people over-eating the wrong types of food.

Each person's needs and requirements are different. Your suitability for the procedure will be discussed with your surgeon, should you wish to book a consultation.
