What postoperative complication might the nurse suspect in a client who experienced fatigue and tingling in the feet after Billroth I surgery?

After Billroth I surgery, which involves resection of part of the stomach and anastomosis to the duodenum, one potential postoperative complication is pernicious anemia. This condition arises due to the decreased production of intrinsic factor, which is necessary for the absorption of vitamin B12.

Patients who have undergone this type of surgery may not adequately absorb vitamin B12 from their diet or supplements, leading to vitamin B12 deficiency. The symptoms of this deficiency, which can include fatigue, weakness, and neurological symptoms such as tingling or numbness in the extremities, align with the client's reported symptoms.

The fatigue the client experiences can stem from anemia, while the tingling in the feet may result from neurological involvement due to prolonged deficiency, ultimately indicating possible peripheral neuropathy. Recognizing these symptoms is crucial for early detection and management of pernicious anemia in these patients, thus addressing both their dietary needs and any potential supplementation of vitamin B12 they may require.
