Understanding the glands that regulate your hormones
The complex orchestration of hormones, affecting every cell of a woman’s body begins with the master regulator, the hypothalamus. In turn the pituitary, ovaries, adrenals and thyroid glands work in unison ensuring the delicate balance of hormones is maintained. This delicate balance can easily become overwhelmed without proper support, especially during stressful periods of life.25
1. The hypothalamus at the base of the brain monitors bodily hormone levels and secretes various hormones which in turn stimulate the pituitary gland. 25
2. The pituitary gland just below the hypothalamus, secretes follicle stimulating hormone (FSH) and luteinising hormone (LH) which act on the ovaries, adrenocorticotropic hormone (ACTH) which acts on the adrenal glands and thyroid stimulating hormone (TSH) which acts on the thyroid gland. Also released from the pituitary is prolactin which influences many tissues throughout the body.27
3. The ovaries then secrete the steroid hormones oestrogen and progesterone, regulating fertility and the menstrual cycle among many other functions. The interplay of hormones in the hypothalamic-pituitary-ovarian [HPO] axis is regulated by a feedback mechanism.28
4. Two small adrenal glands sit above the kidneys and release stress hormones such as cortisol, epinephrine and norepinephrine as well as DHEA and androgens. The hypothalamic-pituitary-adrenal axis (HPA) is also regulated by a feedback mechanism.29
5. The thyroid gland regulates temperature and metabolic processes and is also regulated by a feedback mechanism.30
How stress affects your hormones
Stress is well known to impact the reproductive system and contribute to dysfunction.31 High cortisol causes suppression of FSH and LH, leading to disruption of normal menstrual cycle function and lower progesterone.32 Women with adrenal fatigue may also experience low progesterone, because their body makes cortisol in preference to progesterone as a compensatory mechanism.
Prolonged exposure to stress can lead to complete impairment of reproductive function.33 There are both nutrients and herbs that are beneficial in addressing elevated stress and altered reproductive function.15,16 These should always be prescribed by a qualified naturopath following a comprehensive health assessment.
