Thyroid Stimulating hormone (TSH), free Triidothyronine (fT3), Free thyroxine (fT4), Body Mass Index (BMI)Abstract
Background: It is well known that Thyroid Hormones play a key role in regulating energy
homeostasis. The association between thyroid hormones and energy expenditure is well established. There is
inverse relationship between obesity and energy expenditure. There is a limited data on thyroid function in
euthyroid obese young individuals. Objectives: The present study was designed to evaluate the relationship
between thyroid function and obesity in euthyroid young individuals. Materials & Methods: Obesity was
defined as per Body Mass Index. (BMI)Undergraduate medical students were grouped as normal, overweight
and obese as per their Body Mass Index Thyroid function was assessed by measuring fT3, fT4 and TSH levels by
using automated chemiluminescence immunoassay system. Results: We found that the levels of TSH showed
significant increase in overweight and obese subjects (p< 0.001) however there was no statistical difference in
the levels of fT3and fT4 in overweight and obese students as compared to normal(p> 0.05). Interpretation &
Conclusion: Our results suggest that thyroid function though within the normal range could be one of several
factors acting in concert to determine body weight in a population. Even slightly elevated serum TSH levels are
associated with an increase in BMI.
