Gastric
bypass surgery combines reducing 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 is 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 is 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. Persons feel satisfied 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.
Our expert advisors and consultants will happily talk you through
the procedure in detail and answer any questions you may have.
