The decline of progesterone affects menopausal women significantly. Progesterone is a hormone that plays a crucial role in regulating the menstrual cycle and supporting pregnancy. Its levels start to fluctuate and generally decline as a woman enters into perimenopause.

Menopause Isn’t All About Estrogen:
In fact, progesterone levels typically decline before estrogen levels. This pattern is primarily due to changes in ovulation. As women approach menopause, ovulation becomes less frequent. Since progesterone is mainly produced by the ovaries after ovulation (in the luteal phase of the menstrual cycle), fewer ovulation events lead to a more noticeable and earlier decline in progesterone levels compared to estrogen.
Estrogen levels also decline as menopause approaches, but this happens more gradually and later compared to progesterone. This imbalance between progesterone and estrogen levels during the perimenopausal period leads to what’s called estrogen dominance and can contribute to various symptoms, such as irregular periods, heavier or lighter menstrual bleeding, and increased premenstrual syndrome (PMS) symptoms.
What is Estrogen Dominance?

The decline in progesterone in relation to a slower decline in estrogen can lead to a state often referred to as “estrogen dominance.” This term describes a condition where the effects of estrogen are more pronounced due to lower levels of progesterone rather than necessarily high levels of estrogen itself.
Many of the symptoms associated with the dreaded “change” are due to this decline in progesterone, resulting in this imbalance of estrogen to progesterone.
Progesterone and Estrogen BFFs:
Think of progesterone and estrogen as BFFs. The relationship between progesterone and estrogen is critical for maintaining hormonal balance and overall health. They are key hormones that work together in the female reproductive system to regulate various bodily functions.
Key Functions of Progesterone Before Menopause:
Progesterone works alongside estrogen to help regulate the menstrual cycle, support the body during pregnancy, improve mood, promote bone health, enhance memory, normalize blood sugar levels, boost libido, improve sleep quality, maintain cardiovascular health, and regulate fluid and electrolyte balance.
In summary, progesterone is integral to many bodily functions related to women’s reproductive health, mental well-being, bone health, cardiovascular maintenance, and overall physical equilibrium. Its decline approaching menopause can lead to a range of symptoms, highlighting its significant role throughout the reproductive years.

What Are the Effects of Progesterone Decline?
Here are the 7 ways progesterone decline affects menopausal women:
- Sleep Disturbances: Progesterone has a natural sedative effect. Its decline can lead to difficulties in falling asleep and staying asleep.
- Mood Fluctuations: Progesterone is associated with mood stabilization. Lower levels can contribute to mood swings, anxiety, and depression.
- Bone Health: Progesterone helps to counteract the effects of estrogen loss on bone density. Reduced levels of progesterone during menopause can, therefore, contribute to an increased risk of osteoporosis.
- Heart Health: Progesterone influences blood pressure and blood vessel health. Its decline may increase the risk of developing cardiovascular issues.
- Menstrual Irregularity: In the perimenopausal period, declining progesterone can lead to irregular menstrual cycles, which can be particularly challenging for female athletes in terms of planning and performance.
- Body Composition Changes: Progesterone helps regulate metabolism and the use of fat for energy. Its decrease can lead to changes in body composition, such as increased central body fat, which might affect athletic performance and overall physical fitness.
- Recovery and Muscle Maintenance: Progesterone has anti-inflammatory properties and may help in muscle recovery. Lower levels could influence recovery times and susceptibility to injury.
Conclusion:
In conclusion, understanding the decline of progesterone during menopause is crucial for managing the associated symptoms and maintaining overall health. As progesterone levels fall, women may experience a range of challenges, from sleep disturbances and mood fluctuations to significant impacts on bone and heart health. Recognizing these changes early on can help in implementing effective strategies to mitigate these effects, such as lifestyle adjustments, dietary changes, and possibly hormone replacement therapy tailored to individual needs. By addressing the imbalance caused by estrogen dominance and supporting the body through this transition, women can enhance their quality of life during menopause and beyond. Becoming proactive about health during menopause isn’t just about adapting to changes—it’s about thriving through them.
