Abstract：
:Stress has been shown to negatively affect the immune system, alter the body's metabolism, and play a strong role in the development of mood disorders. These effects are mainly driven through the release of hormones from the hypothalamic-pituitary-adrenal axis (HPA). Additionally, women are more likely to be affected by stress due to the estrogen fluctuation associated with their menstrual cycle. This study aims to evaluate the effect of chronic restraint stress, applied for 30 days, and estrogen replacement on behavior, glucose level, and the lipid profile of ovariectomized rats. Our results suggest that stress increases sweet food consumption in OVX females treated with estradiol (E2), but reduces consumption in animals not treated. Furthermore, stress increases locomotor activity and anxiety as assessed by the Open Field test and in the Elevated Plus Maze. Similarly, our results suggest that E2 increases anxiety in female rats under the same behavioral tests. In addition, stress reduces glucose and TC levels. Moreover, stress increase TG levels in the presence of E2 and decrease in its absence, as well as the estradiol increase TG levels in stressed groups and reduced in non-stressed groups. Our data suggest an important interaction between stress and estrogen, showing that hormonal status can induce changes in the animal's response to stress.
