Correlation of Hypothyroidism and Obesity
Obesity and hypothyroidism are common diseases, and consequently clinicians should be particularly alert for the possible thyroid dysfunction in obese patients. The relationship between thyroid function and obesity is likely to be bidirectional, with hypothyroidism affecting weight, but obesity also influencing thyroid function. Both serum thyroid-stimulating hormone and fT3 are typically increased in obese individuals, likely mediated by leptin. Following LT4 treatment for overt hypothyroidism, weight loss appears due to water weight rather than fat. Selected thyroid analogs might be a means to improve weight loss by increasing energy expenditure in obese patients during lasting hypocaloric diet.
