Perimenopause Care
Navigating hormonal transitions with personalized, evidence-based care.
At Three Rivers Medicine in St. Louis, Missouri, our physician-led primary care perimenopause care provides comprehensive evaluation and management for women experiencing symptoms related to the transitional phase before menopause. This stage, known as perimenopause, involves hormonal fluctuations that can affect menstrual patterns, mood, sleep, and overall well-being. Perimenopause care within a primary care context means your symptoms are evaluated in the full context of your health, not dismissed as “just hormones.” Concierge medicine at Three Rivers extends this model with extended visit time, preventive focus, and deep coordination with specialists when needed.
Perimenopause is a natural biological transition that can begin years before menopause, typically in the late 30s to mid-40s. During this time, estrogen and other hormone levels fluctuate significantly, leading to symptoms that overlap with other health conditions. Primary care physicians are uniquely positioned to assess these changes, integrate lab results, and coordinate care for coexisting issues like thyroid dysfunction, sleep disorders, metabolic transitions, and cardiovascular risk.
Recent clinical observations suggest anywhere from 40–80% of women experience perimenopausal symptoms significant enough to seek medical care, including vasomotor changes (hot flashes), mood disturbances, sleep disruption, and menstrual irregularities. Personalized, physician-supervised care helps distinguish perimenopause from other conditions and tailor treatment plans accordingly.
What Is Perimenopause?
Perimenopause refers to the period leading up to menopause when the ovaries begin to produce less estrogen and progesterone. This hormonal transition can last several years and may begin in the late 30s or early 40s, though the timing varies by individual. Symptoms arise from fluctuating hormone levels and may include irregular periods, hot flashes, night sweats, sleep disturbances, mood swings, decreased libido, and changes in menstrual flow.
Not everyone experiences every symptom, and severity can vary widely. Because symptoms overlap with other health conditions — such as thyroid disorders, sleep apnea, anxiety, or metabolic changes — a thorough medical assessment is essential to avoid misdiagnosis.
Common Perimenopausal Symptoms We Assess
- Irregular menstrual cycles and changes in bleeding patterns
- Hot flashes and night sweats
- Mood swings, anxiety, or depression
- Sleep disturbances or insomnia
- Decreased libido or vaginal dryness
- Weight changes or altered metabolism
- Memory or concentration issues (“brain fog”)
Why Physician-Led Care Matters
Perimenopause care that is physician-led and integrated into primary care provides continuity and coordination. Unlike symptom-specific clinics or oversimplified online interventions, primary care contextualizes symptoms within your broader health — including cardiovascular, metabolic, and mental health. This approach helps avoid misdiagnosis or ineffective treatment plans.
Women’s health transitional phases often require careful interpretation of symptoms because hormonal changes may mimic or mask conditions like thyroid disease, depression, or sleep disorders. Evidence supports comprehensive assessment over isolated symptom treatment.
How Primary Care-Based Perimenopause Care Works
Step 1: Detailed Medical Evaluation
Your clinician conducts an in-depth review of symptoms, medical history, and lifestyle. This includes documenting menstrual cycle changes, sleep patterns, mood concerns, and other health indicators that may influence your transition. Primary care evaluation ensures symptom context is not overlooked.
Step 2: Targeted Diagnostic Testing
While hormone levels fluctuate and single tests may not definitively diagnose perimenopause alone, lab work can be helpful in ruling out other causes such as thyroid dysfunction, anemia, or metabolic imbalances. Testing is ordered thoughtfully to guide medical decisions rather than as routine screening in every case.
Step 3: Personalized Care Plan
If perimenopause is contributing to your symptoms, your clinician creates a personalized plan. This may include hormone therapy when indicated, non-hormonal treatment options, lifestyle support strategies, and coordination with specialists such as cardiology or endocrinology when complex needs arise.
Step 4: Monitoring and Follow-Up
Perimenopause is a dynamic state; symptoms and health priorities change over time. Regular follow-up visits allow your physician to monitor symptom progression, adjust treatment plans, and manage related health factors such as bone health or cardiovascular risk.

Frequently Asked Questions
What is perimenopause and when does it start?
Perimenopause is the transitional phase before menopause when estrogen and progesterone levels begin to fluctuate, often causing symptoms like irregular periods, hot flashes, mood changes, sleep disruption, and brain fog. According to the North American Menopause Society (NAMS), it can begin 4 to 8 years before menopause, with the average onset in the mid-40s — though some women experience symptoms as early as their late 30s. At Three Rivers Concierge Medicine in St. Louis, Dr. Shoemaker evaluates these symptoms in context rather than dismissing them as "just stress."
How do I know if my symptoms are perimenopause or something else?
That's exactly why physician-led evaluation matters — perimenopausal symptoms overlap significantly with thyroid dysfunction, depression, anxiety, sleep disorders, and metabolic changes. Dr. Shoemaker orders targeted labs and reviews your complete health picture to distinguish hormonal transition from other treatable conditions. Getting the diagnosis right is the difference between effective treatment and months of trial-and-error with the wrong approach.
Do you automatically prescribe hormones for perimenopause?
No — Dr. Shoemaker evaluates whether hormones are appropriate based on your specific symptoms, health history, risk factors, and lab results, consistent with guidelines from both the North American Menopause Society and the Endocrine Society. Some patients benefit from hormone therapy; others respond better to lifestyle modifications, non-hormonal treatments, or addressing underlying conditions like thyroid dysfunction. The goal is the right treatment for your situation, not a default protocol.
How is perimenopause care at Three Rivers different from a hormone clinic?
Hormone clinics and med spas typically focus on one thing: prescribing hormones. At Three Rivers, perimenopause care is integrated into primary care, which means Dr. Shoemaker also monitors your cardiovascular health, metabolic function, bone density, mental health, and overall well-being — not just your hormone levels. This matters because perimenopause affects your entire body, and treating it in isolation misses the bigger picture.
What labs do you order for perimenopause?
Lab work may include estradiol, FSH, progesterone, testosterone, thyroid panel (TSH, free T3, free T4), metabolic markers, CBC, and vitamin levels — chosen based on your symptoms and clinical picture, not run as a blanket panel. Dr. Shoemaker interprets these results in context, because hormone levels fluctuate during perimenopause and a single snapshot rarely tells the full story. Testing is thoughtful and targeted at our Creve Coeur office, not reflexive.
Can perimenopause cause anxiety and depression?
Yes — research published in JAMA Psychiatry confirms that hormonal fluctuations during perimenopause directly affect serotonin, dopamine, and other neurotransmitters that regulate mood, with women 2 to 4 times more likely to experience a depressive episode during this transition. These symptoms are frequently misdiagnosed and treated with antidepressants alone when the underlying hormonal shift is the primary driver. Dr. Shoemaker at Three Rivers evaluates whether your mood symptoms are hormonally mediated before recommending treatment.
Is perimenopause care covered by insurance?
The physician visits, lab work, and prescribed medications associated with perimenopause evaluation and treatment are typically billable through insurance. Your concierge membership at Three Rivers covers the extended visit time, direct physician access, and ongoing monitoring that makes this care thorough and responsive.
