| Abstract: | Objective: The holy month of Ramadan poses a challenge for levothyroxine-treated patients due to altered eating habits and time restrictions. The aim of this study was to examine the impact of lifestyle changes during Ramadan on thyroid function tests in hypothyroid patients taking levothyroxine in the United Arab Emirates.Methods: Retrospective design whereby levothyroxine-treated hypothyroid patients who had thyroid function tests within 3 months pre-Ramadan and within 2 months post-Ramadan were included. We looked at adherence to levothyroxine, eating pattern, and levothyroxine administration in relation to meal times during Ramadan. Pre- and post-Ramadan thyroid function tests and the potential impact of independent variables using a random-intercept mixed effects linear model were examined.Results: A total of 112 patients (89 females) were recruited in the study, with a mean age ± standard error (SE) of 44.70 ± 1.36 years (range, 19.0 to 79.0 years). The mean thyroid-stimulating hormone (TSH) within 3 months before Ramadan was 1.809 ± 0.094 mIU/L (median, 41.5 days; interquartile range [IQR], 25.0 to 73.0 days), while the mean TSH within 2 months post-Ramadan was higher at 3.072 ± 0.312 mIU/L (median, 27.5 days; IQR, 14.0 to 42.0 days). Post-Ramadan, 36 out of 112 patients had a plasma TSH outside of the normal reference range. The independent variable outcomes model showed that older patients and males were more likely to have an increased plasma TSH post-Ramadan. There was no relationship between the time of levothyroxine administration and change in TSH level.Conclusion: Levothyroxine-treated hypothyroid patients showed a significant increase in plasma TSH post-Ramadan, amounting to 2.525 standard deviations, with older patients and males more likely to be affected.Abbreviations: IQR = interquartile range; T4 = thyroxine; TSH = thyroid-stimulating hormone |
