Metabolic syndrome in thyroid disease.

Abstract

Cardiometabolic risk factors like abdominal obesity, hyperglycemia, low high-density lipoprotein (HDL) cholesterol, elevated triglycerides, and hypertension are defined as metabolic syndrome (MetS), which represents one of the most frequent endocrine disorders particularly in a society with increasing weight problems. As more and more evidence is accumulated that thyroid hormones affect components of the MetS, the present review aims to summarize the rapidly expanding knowledge on the pathophysiological interaction between thyroid hormone status and MetS. The review is based on a PubMed search for combinations of thyroid hormone action and MetS, blood pressure, hypertension, hyperlipidemia, cholesterol, HDL cholesterol, glucose, diabetes mellitus, body weight, or visceral fat. A special focus was given for manuscripts published after 2000 but we included seminal papers published before year 2000 as well.
