Climacteric symptoms are related to thyroid status in euthyroid menopausal women

Background Climacteric symptoms are a variety of disturbing complaints occurring during menopausal transition, many of which may be influenced by hormonal abnormalities other than related to sex steroids. Aim of the study In this study, we investigated the association between the intensity of climacteric symptoms measured with the Kupperman index and a thyroid status. Material and methods We evaluated by measuring serum thyrotropin (TSH), and free thyroxine (fT4) 202 euthyroid women admitted to the Department of Gynecological Endocrinology, Poznan University of Medical Sciences because of climacteric symptoms. Patients were both in perimenopause (n = 74) and postmenopause (n = 128), with no history of thyroid disorders. Results Results presented as the mean value and standard deviation were as follows: age 54.2 +/- 4.9 years, BMI 26.8 +/- 4.6 kg/m(2), Kupperman index 26 +/- 13.1 points, TSH 2.4 +/- 2.6 mU/l, fT4 1.2 +/- 0.37 ng/dl. We observed a negative correlation between fT4 and the time since the last menses (R = - 0.38; p = 0.02) as well as between serum TSH concentration and sweating (R = - 0.18; p = 0.03), general weakness (R = - 0.17; p = 0.03), and palpitation (R = - 0.18; p = 0.02) and a positive correlation between fT4 and nervousness (R = 0.34; p = 0.007) and palpitations (R = 0.25; p = 0.04). In the perimenopausal subgroup, there was a positive correlation between fT4 and general weakness (R = 0.42; p = 0.03), palpitations (R = 0.50; p = 0.009), and paresthesia (R = 0.46; p = 0.01). In the postmenopausal subgroup, there was a negative correlation between TSH and sweating (R = - 0.21; p = 0.03). Conclusions Menopausal symptoms are related to thyroid status in euthyroid menopausal women.
