What dietary modification is most likely prescribed for an older adult after a subtotal gastrectomy?

After a subtotal gastrectomy, it's essential for an older adult to adjust their dietary intake to accommodate changes in digestion and absorption that occur after part of the stomach has been removed. The correct approach is to resume small, easily digested feedings gradually. This strategy helps minimize symptoms such as dumping syndrome, which can occur when larger amounts of food enter the intestines too quickly.

Smaller, more frequent meals can also enhance nutrient absorption and ensure that the individual is able to consume enough calories and nutrients without overwhelming their altered digestive system. Foods that are easily digestible will also help in reducing gastrointestinal discomfort and aid in recovery.

In contrast, other options like eating three large meals a day could lead to discomfort and digestive issues, especially since the stomach capacity has been reduced. Eliminating all protein from the diet would be detrimental, as protein is crucial for healing and maintaining muscle mass. Likewise, beginning a high-fiber diet immediately may not be advisable, as the digestive system needs time to adjust post-surgery, and high-fiber foods can exacerbate gastrointestinal upset if introduced too soon.
