Sleep disturbances before and after parathyroidectomy for secondary hyperparathyroidism

Preoperatively, a high prevalence of sleep disturbances (97%) was found in patients with symptomatic secondary hyperparathyroidism. We conclude that nocturnal melatonin levels do not change after parathyroidectomy; the improvements in sleep disturbance and the decreases in severity of insomnia are found 3 months after surgery in association with longer sleep hours per night. Decreases of symptoms such as skin itching, bone pain, and general weakness may be the reasons for the improvement in sleep and the decrease in insomnia.
