The Central Effects of Thyroid Hormones on Appetite

Abstract EN

Obesity is a major public health issue worldwide.

Current pharmacological treatments are largely unsuccessful.

Determining the complex pathways that regulate food intake may aid the development of new treatments.

The hypothalamic-pituitary-thyroid (HPT) axis has well-known effects on energy expenditure, but its role in the regulation of food intake is less well characterised.

Evidence suggests that the HPT axis can directly influence food intake.

Thyroid dysfunction can have clinically significant consequences on appetite and body weight.

Classically, these effects were thought to be mediated by the peripheral effects of thyroid hormone.

However, more recently, local regulation of thyroid hormone in the central nervous system (CNS) is thought to play an important role in physiologically regulating appetite.

This paper focuses on the role of the HPT and thyroid hormone in appetite and provides evidence for potential new targets for anti-obesity agents.
