Estrogen plays an important role in a woman’s body throughout life. But after 40, its balance with other hormones like progesterone begins to shift. This can lead to a common but overlooked condition called estrogen dominance.
At Skinny Seattle, we work with women who feel off but are told their hormones are “fine.” In this blog, we explain estrogen dominance, how it impacts weight and mood, and how lab testing helps uncover what is really going on.
What Is Estrogen Dominance?
Estrogen dominance occurs when estrogen is too high relative to progesterone. This does not always mean estrogen itself is abnormally high. Sometimes, progesterone is just too low, making estrogen effects more pronounced.
This imbalance can cause a variety of uncomfortable symptoms, especially during perimenopause and postmenopause when hormone levels fluctuate.
Common Symptoms of Estrogen Dominance
Women often blame themselves for how they feel. But these symptoms are not about willpower. They are about hormones that need support.
You might be dealing with estrogen dominance if you experience:
- Weight gain, especially around the hips and thighs
- Breast tenderness
- PMS or irregular periods
- Mood swings or anxiety
- Fatigue and sleep disturbances
- Brain fog
- Water retention or bloating
- Headaches or migraines
If several of these sound familiar, it is time to explore what your hormones are doing behind the scenes.
Root Causes of Estrogen Dominance
Hormone balance depends on multiple systems working in harmony. Here are some of the most common contributors to estrogen dominance:
- Perimenopause: Natural hormone shifts often result in lower progesterone, making estrogen appear dominant.
- Chronic stress: High cortisol suppresses progesterone production.
- Poor liver detoxification: Your liver is responsible for clearing excess estrogen.
- Gut health issues: Estrogen can recirculate in the body if digestion is impaired.
- Environmental toxins: Chemicals in plastics, cosmetics, and food can act like estrogen in the body.
- Obesity or high body fat: Fat tissue produces estrogen, which can worsen imbalance.
At Skinny Seattle, we address these causes using a root-cause approach rather than just treating symptoms.

The Impact of Estrogen Dominance on Weight
Estrogen dominance is a major reason why midlife weight gain becomes so frustrating. This hormonal state promotes fat storage, especially in the lower body and abdomen. It also slows metabolism, increases water retention, and can cause cravings and emotional eating.
You may find that the same habits that once worked for you no longer make a difference. The real solution lies in restoring hormonal harmony, not just cutting calories.
How We Identify Hormone Imbalance
Most traditional doctors do not test for hormone ratios. They may check basic levels but miss the patterns that matter.
We use comprehensive lab testing to help us build a clear map of what is happening in your body and what to target with care.

Frequently Asked Questions
What is estrogen dominance and why does it happen after 40?
Estrogen dominance means there is too much estrogen compared to progesterone. It often happens in midlife as progesterone drops faster than estrogen.
Can estrogen dominance cause weight gain?
Yes. It promotes fat storage in the hips, thighs, and belly and can increase water retention and slow metabolism.
