Precision Hormone Testing • Personalized Care • Real Answers for Midlife Women
Perimenopause isn’t “just aging.”It’s a hormone transition that impacts your brain, mood, metabolism, sleep, heart, gut, and relationships — often long before your period stops.
At Precision Health MD in Fullerton, CA, we specialize in helping women finally understand what’s happening in their bodies and get a clear, personalized plan that restores energy, mood, sleep, metabolism, and confidence.
You don’t have to feel overwhelmed, dismissed, or “not yourself” anymore. You deserve care that listens deeper, asks better questions, and treats you — not “normal” lab ranges.

What Is Perimenopause?
Perimenopause is the transition leading up to menopause and can start as early as age 35.
Hormones don’t decline gently — they swing wildly, causing symptoms that feel random, confusing, and often misdiagnosed.
The most common symptoms include:
-
Unpredictable periods
-
Heavy bleeding or clotting
-
PMS that feels “different”
-
Mood swings or irritability
-
Anxiety or heart palpitations
-
Brain fog or memory lapses
-
Sudden fatigue
-
Poor stress tolerance
-
Weight gain (especially midsection)
-
Night sweats or hot flashes
-
Insomnia or 3 a.m. wake-ups
-
Low libido
-
Vaginal dryness or pain
-
Headaches or migraines
-
Skin changes & hair thinning
If you feel like your body changed overnight — you’re not imagining it.
Why Symptoms Get Dismissed
Most women never get real answers because:
Standard lab ranges miss early hormone changes
Most OB/GYNs aren’t trained in integrative hormone care
Symptoms get labeled as “stress,” “aging,” “anxiety,” or “normal”
You’re told to “wait until menopause”
You’re offered a pill, not an explanation
No one looks at how hormones affect your whole system
At Precision Health MD, we change that. We listen deeply, connect the dots, and treat the root causes — not just manage symptoms.
Personalized Integrative Treatment Plan
Treatment may include:
Bioidentical Hormone Therapy (BHRT)
Customized dosing of estrogen, progesterone, and testosterone when appropriate.
Sleep & Mood Optimization
Targeting how hormones affect brain neurotransmitters.
Metabolic & Weight Support
Insulin resistance often rises in perimenopause — we address it directly.
Stress & Nervous System Regulation
Perimenopause makes your system more reactive; we help stabilize it.
Gut–Hormone Connection
Because microbiome shifts affect estrogen balance.
Lifestyle, nutrition, supplements, and precision diagnostics
Evidence-based, personalized, and supportive.

Integrative Women's Health FAQ
Integrative women's health combines conventional medical treatments with evidence-based complementary approaches to address the root causes of health issues. This holistic approach considers nutrition, lifestyle, stress management, hormones, and environmental factors to optimize women's health throughout all life stages, from reproductive years through menopause and beyond.
While conventional gynecology focuses primarily on diagnosing and treating symptoms with medications or surgery, integrative medicine looks deeper to find and address root causes. We use advanced lab testing to identify underlying imbalances in hormones, nutrients, gut health, and metabolism. Treatment plans include personalized nutrition, lifestyle modifications, supplements, and stress management alongside conventional treatments when needed. The goal is sustainable healing, not just symptom management.
We treat a wide range of women's health conditions including PCOS (polycystic ovary syndrome), endometriosis, irregular periods, PMS and PMDD, thyroid disorders (including Hashimoto's), infertility, perimenopause and menopause symptoms, hormone imbalances, chronic fatigue, digestive issues like SIBO and IBS, autoimmune conditions, weight management challenges, and overall health optimization for women at any life stage.
Yes, we offer bioidentical hormone replacement therapy for women experiencing perimenopause, menopause, or hormone imbalances. BHRT uses hormones that are molecularly identical to those your body produces naturally. We start with comprehensive hormone testing, then create personalized treatment plans that may include estrogen, progesterone, testosterone, and thyroid optimization. We carefully monitor your progress and adjust dosing to achieve optimal symptom relief while prioritizing safety.
Your first appointment typically lasts 60-90 minutes. Dr. Roelands will review your complete health history, current symptoms, lifestyle factors, diet, stress levels, sleep patterns, and health goals. She'll discuss any previous lab work and may recommend comprehensive testing to assess hormones, nutrient levels, thyroid function, metabolic markers, and gut health. By the end of your visit, you'll have a clear understanding of potential root causes and a personalized treatment plan to begin your healing journey.
Yes, we specialize in thyroid disorders including Hashimoto's thyroiditis. Our approach goes beyond just treating TSH levels. We perform comprehensive thyroid testing including TSH, Free T3, Free T4, Reverse T3, and thyroid antibodies. We address root causes such as gut health issues, nutrient deficiencies (selenium, zinc, vitamin D, iron), chronic inflammation, and food sensitivities. Treatment includes personalized nutrition plans, gut healing protocols, stress management, appropriate thyroid medication when needed, and regular monitoring to optimize your thyroid function and reduce antibodies.
We offer a comprehensive approach to menopause that can include both natural and conventional options based on your preferences and needs. Natural approaches include specific dietary changes to support hormone balance, phytoestrogen-rich foods, targeted supplements like black cohosh or evening primrose oil, stress reduction techniques, sleep optimization, and exercise programs. For women who need more support, we offer bioidentical hormone therapy. We work with you to find the right combination that relieves hot flashes, night sweats, mood changes, sleep disruption, and other symptoms while supporting long-term bone and cardiovascular health.
