Purpose:
to evaluate the effect of hormone replacement therapy (HT) on the weight on perimenopausal women as well as the effect of different treatment regimens on this parameter.
Methods:
a retrospective study of 139 women with menopause for less than 2 years, who were monitored with periodical visits in our department. We compared two groups: women who started HT (n=89) with women who had no hormonal treatment (n=50) and in the two groups, we evaluated the changes in body weight over a 1-year period. In the first group, we assessed the same parameter as a function of different treatment regimens: estrogen alone versus estrogen combined with progestin and standard dose versus low dose. The SPSS® program was used for statistical analysis, with the level of significance set at p<0.05.
Results:
the groups were similar with respect to demographic and baseline characteristics; weight gain was higher in the untreated group (434 vs 76 g), but the difference observed was not significant (p = 0.406); among HT users, those taking estrogen alone had an increased weight gain compared to women taking estrogen with progestin (775 vs 24 g), although no statistically significant difference was observed and the same applied when comparing the dose initially prescribed (92 vs 49 g).
Conclusions:
despite the common belief about weight gain associated with HT, the results of the present study seem to contradict this point, with no additional weight gain beyond that normally associated with this period in a woman's life.

Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
