A common complication during hemodialysis is hypotension. This condition can occur due to several factors associated with the dialysis process. During hemodialysis, excess fluid is removed from the blood, which can lead to a sudden drop in blood volume. As the volume decreases, blood pressure may fall, resulting in hypotension.

Additionally, the rapid removal of fluid can lead to changes in electrolyte levels and trigger vasodilation, further contributing to a decrease in blood pressure. Symptoms of hypotension during dialysis can include dizziness, nausea, vomiting, and in severe cases, loss of consciousness. It's crucial for dialysis staff to monitor patients closely for signs of hypotension and to manage any drops in blood pressure appropriately.

The other conditions mentioned are less commonly seen as direct complications of hemodialysis. Dehydration can be a concern, but it is more related to the patient's overall fluid balance rather than a direct complication of the dialysis session itself. Hypoglycemia may occur in diabetic patients undergoing treatment, but it is not a typical complication of the dialysis process. Hyperthermia is also not a common issue during hemodialysis; instead, the treatment typically aims to maintain normothermia.
