Your stomach has been surgically reduced in size.

The stomach is located in the upper left abdomen. The stomach stores food and breaks it down further. Harmful pathogens are also killed by gastric acid in the stomach. The stomach thus prepares the food for digestion in the intestines. and is connected to the gullet (oesophagus) at its upper end and with the first part of the small intestine at its lower end. There is a sphincter muscle between the stomach and the small intestine known as the pylorus.

The operation removed a large part of your stomach. This has made your stomach’s capacity far less than it was previously.

The operation also involved removing your pylorus and a small section of the beginning of your small intestine. The open end at the top of your small intestine was then stitched shut. A part of your small intestine further down was then stitched to the remaining upper section of your stomach.

Post-surgery, food is now getting from your stomach straight to the part of your small intestine that is lower down. So food is no longer being moved through the top section of your small intestine. However, the digestive juices from your liver and pancreas are still flowing into that section of your small intestine. The digestive juices then blend with the food lower down in the small intestine.

As a result of the operation, food is passing through your stomach and intestine more quickly. So your body is absorbing fewer food components.

The operation involved opening your abdomen via an incision.
