Alterations of the levels of the thyroid hormones and the metabolic syndrome
Main Article Content
Abstract
Introduction. More than 10% of the population suffers from alterations in Thyroid hormone levels without knowing who suffers from it, the diagnosis is made with low levels of thyroid hormones and elevated TSH, this pathology is more common in women. Both hypothyroidism and hyperthyroidism can lead to cardiovascular events, arrhythmias, and heart failure. Objective. Determine the impact of Thyroid Hormones on lipid components, triglycerides and HDL cholesterol levels, because they are part of the definition of Metabolic Syndrome. Methodology. A systematic bibliographic review, with information from meta-analysis-type articles, systematic reviews, and case-control studies. Results. When there are alterations in the function of the Thyroid Hormone, they can coexist with the Metabolic Syndrome, which is diagnosed when the person has three or more of the following features, or takes medications to control them, waist circumference greater than 89 centimeters in women and 102 centimeters in males; Elevated triglyceride levels greater than 150 mg / dl; High-density lipoprotein (HDL) cholesterol less than 50 mg / dl in women and 40 mg / dl in men; High blood pressure and high fasting glucose. Both are significantly associated with morbidity and mortality and therefore have a substantial impact on health care, worldwide. Conclusion. Subclinical Hypothyroidism is more frequent in women and the risk increases with age, therefore, greater attention must be paid to the risk of developing Metabolic Syndrome. Likewise, the Subclinical Hypothyroidism group was significantly associated with a higher risk of developing Metabolic Syndrome.
