Other drivers of hormonal disharmony

We’ve just talked about stress as a key driver of hormonal imbalance. For many women, especially in perimenopause and menopause, this is the biggest factor. By our late 30s, 40s, and 50s, the habits we “got away with” earlier often stop working. At the same time, protective hormones naturally decline, which can intensify symptoms. Let’s look at other common drivers. Not ovulating. If you’re having anovulatory cycles, you won’t produce progesterone from the corpus luteum. Less ovulation means less progesterone, which tips the balance toward estrogen. Synthetic hormones. Oral contraceptives and some hormonal coils work by suppressing ovulation. The bleed you see on the pill is a withdrawal bleed, not a true menstrual period. Progestin-only options use progestins, which do not act like bioidentical progesterone and can still reduce true progesterone exposure. Over time, this can contribute to imbalances. HRT configuration. We’ll go deeper later, but an estrogen-only approach or using progestins instead of bioidentical progesterone can drive symptoms. Even with bioidenticals, the ratio matters. Too little progesterone relative to estrogen can keep you symptomatic. Xenoestrogens. Our modern environment contains compounds that behave like estrogens. These can be found in certain plastics, synthetic fabrics, home and body products, and even tap water. Some foods contain phytoestrogens, which can be supportive in balance, but an over-reliance without dietary diversity can nudge the system. Alcohol. It can destabilize blood sugar, burden the liver, and worsen hormonal symptoms. Weight. Excess adipose tissue increases aromatization, converting androgens to estrogens. Conversely, being underweight or chronically restricting calories can suppress ovulation, raise cortisol, slow thyroid function, and lower progesterone. Fasting and under-eating. Skipping meals, especially breakfast, can spike cortisol and drop blood sugar, driving more stress signaling and pulling resources away from progesterone. Gut and liver function. Estrogen needs to be metabolized and cleared. If the liver is overburdened or digestion is sluggish, estrogen can recirculate, contributing to estrogen dominance. Thyroid. Low thyroid function reduces progesterone production and impairs the T4 to T3 conversion. Estrogen dominance can further slow thyroid conversion, creating a loop. Nutrient gaps. B6 supports corpus luteum function. Retinol supports steroid hormone synthesis from cholesterol. Vitamin D, zinc, magnesium, and vitamin C all play roles in hormonal balance and stress resilience. Light exposure. Inadequate daylight and excessive artificial light, especially at the wrong times, can dysregulate circadian rhythms, appetite hormones, ovulation cues, and progesterone signaling. We’ll translate this into clear lifestyle steps later. So beyond stress, think about ovulation status, contraception history, HRT balance, environmental exposures, alcohol, weight patterns, eating rhythm, gut and liver health, thyroid function, nutrient status, and light. Notice what resonates for you. Next, we’ll do a practical action for this module, then move into nutrition in The Nourished Woman.
