Overview
Estrogen is essential for both females and males, responsible for developing secondary sexual characteristics, regulating bone, heart and brain health. Elevated estrogen can cause a hormonal imbalance and result in several reproductive health issues. This blog explains what causes high estrogen levels, symptoms and how to restore the hormonal balance.
What Is High Estrogen?
Estrogen is a key sex hormone that regulates reproductive health, supports bone density and helps maintain metabolic balance. While essential for normal development and sexual characteristics during puberty, abnormally high estrogen levels can disrupt the menstrual cycle and contribute to conditions such as endometriosis, polycystic ovary syndrome (PCOS), fibroids and infertility. Both excess and deficiency of estrogen can affect metabolic, neurological and gender-specific health. Alongside progesterone, estrogen also plays a crucial role in preparing the body for pregnancy.
What Are the Symptoms of High Estrogen in Females and Males?
Females: In females, estrogen plays an important role in puberty and the development of secondary sexual characteristics. Also, it plays a role in regulating the menstrual cycle and maintaining reproductive health. Elevated estrogen levels in women often lead to physical and emotional symptoms such as:
- Bloating
- Water retention
- Breast swelling and tenderness
- Difficulty sleeping
- Fatigue or low energy levels
- Fibrocystic breasts
- Fibroids
- Headaches or migraines
- Irregular or heavy menstrual periods
- Decreased libido
- Mood swings and irritability
- Weight gain in the area of the waist, hips and thighs
- Worsening premenstrual syndrome symptoms
Males: In males, estrogen is produced in small amounts, primarily to maintain bone density and reproductive health. It is essential for sperm production, libido and sexual arousal. The elevated estrogen level in males can disrupt hormonal balance and lead to symptoms such as:
- Enlarged breast tissue
- Erectile dysfunction
- Infertility
- Loss of libido
- Mood changes
- Dry skin
What Causes High Estrogen Levels?
Estrogen levels can be elevated due to a variety of exogenous and endogenous factors, including underlying medical conditions, medication/hormonal therapy and environmental changes.
Underlying medical conditions:
Certain health conditions can increase estrogen production or reduce its breakdown, leading to elevated levels. These include:
- Polycystic ovary syndrome (PCOS)
- Uterine fibroids and endometriosis
- Obesity (excess fat tissue can produce estrogen)
- Hyperthyroidism
- Liver disease (affecting hormone metabolism)
- Ovarian or testicular tumors
- Adrenal gland disorders
Medications and Hormonal Therapies:
Some drugs can raise estrogen levels, either directly or indirectly. These include:
- Hormonal contraceptives (birth control pills)
- Hormone replacement therapy (HRT)
- Select medications, such as certain antidepressants and cardiovascular drugs (less common and often indirect)
Environmental and Lifestyle Factors:
External factors can also disrupt estrogen balance:
- Exposure to xenoestrogens in plastics, pesticides and personal care products
- Diets high in processed foods or alcohol
- Chronic stress, which can alter the progesterone-to-estrogen ratio
By addressing these causes, it is often possible to restore normal estrogen levels and reduce symptoms.
What Are Risk Factors If Untreated High Estrogen?
If high estrogen is left unmanaged, it can increase the risk of several health complications affecting multiple systems in the body:
Reproductive Health Issues
In women, excess estrogen can lead to irregular or heavy menstrual cycles, endometriosis and uterine fibroids. In men, it may contribute to infertility and reduced sexual function.
Increased Cancer Risk
Chronically elevated estrogen, especially without adequate progesterone, is linked to higher risks of:
- Estrogen-receptor-positive breast cancer
- Endometrial (uterine) cancer due to abnormal endometrial growth
- Ovarian and prostate cancers
Metabolic Disorders
High estrogen can promote fat accumulation, particularly in the hips, thighs and waist. Hormonal imbalance may also lead to insulin resistance, increasing the risk of type 2 diabetes and obesity.
Cardiovascular Complications
Hormonal imbalance from elevated estrogen can increase the risk of blood clots, stroke and high blood pressure.
Bone Health
While estrogen usually supports bone density, long-term hormonal imbalance can indirectly contribute to weight-related strain and reduced bone health if associated with other metabolic issues.
Mental and Emotional Health
High estrogen may trigger mood disorders such as irritability, anxiety or depression. Prolonged hormonal imbalance can also affect cognitive and brain health over time.
How to Diagnose if Estrogen Level Is Increased?
High estrogen is diagnosed primarily through laboratory testing. The most common method is a blood test, which measures the levels of estrogen in the circulation. Less frequently, estrogen levels can be assessed using saliva or urine tests, but blood testing remains the standard for accuracy.
Estrogen exists in three main forms, and testing may focus on one or more depending on age, sex or clinical situation:
- Estrone (E1): The main estrogen after menopause; supports bone health and other estrogen-related functions.
- Estradiol (E2): The most biologically active and abundant form; regulates the menstrual cycle, supports reproductive and bone health and is essential during puberty.
- Estriol (E3): Produced in large amounts during pregnancy; vital for fetal development.
A healthcare provider evaluates these results alongside symptoms, medical history and other hormone levels to determine if estrogen is abnormally high and to guide appropriate treatment.
What Are Treatment Options for High Estrogen?
Managing high estrogen involves a combination of medical treatment, lifestyle changes and environmental adjustments. The approach depends on the underlying cause and severity of the hormonal imbalance.
Address Underlying Medical Conditions
Treating conditions that contribute to high estrogen can help restore hormonal balance. This includes managing:
- Polycystic ovary syndrome (PCOS)
- Obesity
- Liver disease
- Thyroid disorders
- Adrenal gland abnormalities
- Uterine fibroids or tumors
Medical Interventions
Medications may be prescribed to regulate estrogen levels or relieve symptoms:
- Hormonal birth control (to balance estrogen and progesterone)
- Hormone blockers or selective estrogen receptor modulators (SERMs)
- GnRH analogues to control hormone production
In certain cases, surgical interventions may be necessary, but only when there are structural abnormalities or tumors causing elevated estrogen. Examples include:
- Adrenalectomy (removal of adrenal glands)
- Oophorectomy (removal of ovaries)
- Myomectomy (removal of uterine fibroids)
Dietary and Lifestyle Management
Lifestyle changes can help support hormonal balance:
- Maintain a healthy weight
- Eat cruciferous vegetables (broccoli, cauliflower, kale)
- Follow an anti-inflammatory diet
- Limit alcohol consumption
- Engage in regular physical activity
Reduce Exposure to Xenoestrogens
Avoid chemicals that mimic estrogen, such as:
- Plastics containing BPA or phthalates
- Certain pesticides
- Some personal care products (lotions, cosmetics)
Combining medical treatment with lifestyle and environmental adjustments can help restore estrogen to normal levels and reduce related symptoms.
Conclusion
High estrogen is more than just a hormonal imbalance; it can affect multiple aspects of health, from reproductive and metabolic function to mental well-being. While lifestyle, environmental exposure and medical conditions can contribute to elevated estrogen, the good news is that it is manageable.
By understanding the symptoms, seeking timely medical evaluation and making targeted lifestyle and dietary changes, individuals can restore hormonal balance, reduce long-term health risks and improve overall quality of life. Early awareness and proactive management are key to preventing complications and supporting lasting health in both women and men.
