Acute effect of propranolol on resting energy expenditure in hyperthyroid patients.

Objective: Hyperthyroidism is a common endocrine disorder which leads to higher resting energy expenditure (REE). Increased activity of brown adipose tissue (BAT) contributes to elevated REE in hyperthyroid patients. For rapid control of hyperthyroid symptoms, the non-selective β-blocker propranolol is widely used.

Resting Energy Expenditure and Cold-induced Thermogenesis in Patients With Overt Hyperthyroidism.

Context: Thyroid hormone (TH) is crucial for the adaptation to cold.

Objective: To evaluate the effect of hyperthyroidism on resting energy expenditure (REE), cold-induced thermogenesis (CIT) and changes in body composition and weight.

Methods: This was a prospective cohort study at the endocrine outpatient clinic of a tertiary referral center.
