How may the normal digestive process change with this procedure?
What will be an ideal response?
• The procedure may change the digestive process both physically and chemically.
• The stomach has been partially resected, which will reduce the holding capacity of the stomach.
• Gastric emptying may also change depending on the status of the pylorus and the vagus nerve and any other anatomical changes.
• Loss of the duodenum reduces the overall surface area for digestion and absorption.
• Nutrition concerns include the potential for vitamin and mineral deficiencies.
• Possible reductions in gastric acidity may result in inadequate iron absorption (due to the acidic environment being necessary to maintain the reduced ferrous state of iron)
• Changes in gastric anatomy may cause inadequate intrinsic factor to be secreted.
- This would prevent normal B12 absorption and lead to a subsequent deficiency.
- Research has confirmed that patients who have had gastric surgery have a high prevalence of vitamin B12 deficiency.
• The duodenum is no longer functional but the jejunum will accommodate the functions of the duodenum over time.
• Initially there may be a reduction in some enzyme function—specifically for lactase (causing typically transient lactose-intolerance).
• Finally, transit time is affected, which may result in dumping syndrome.
