Which of the following is a common complication of dialysis that requires monitoring?

Anemia is a common complication of dialysis that requires ongoing monitoring due to the way dialysis affects the kidneys' ability to produce erythropoietin, a hormone that stimulates red blood cell production. Patients on dialysis often experience a decrease in red blood cell count because their kidneys cannot produce sufficient erythropoietin, leading to chronic anemia.

Moreover, the removal of blood during the dialysis process can result in the loss of red blood cells. This is particularly crucial to monitor because anemia can cause fatigue, weakness, and an overall decline in quality of life for patients. Managing anemia typically involves regular blood tests to check hemoglobin levels, along with treatments like erythropoiesis-stimulating agents or iron supplementation to help boost red blood cell production.

While constipation, nausea, and headaches can also occur in dialysis patients, they do not carry the same level of significance or prevalence as anemia, which specifically impacts the hematologic status of these patients and requires careful observation and management to prevent further complications.
