Following a subtotal gastrectomy, the patient is at risk for dumping syndrome. To prevent this, the nurse should instruct the patient to eat multiple small meals per day. Simple carbohydrates should be avoided, so fat intake must be increased to ensure adequate nutrition. Lying supine for 30 minutes may help delay emptying and prevent hypotension after eating. Although soy milk may be better tolerated than dairy products, there is still sugar in soy ice cream that may cause late dumping. The patient should avoid dairy products such as Greek yogurt, even though it is plain.
