Our Root-Cause Investigation Methodology
Functional Root uses a structured, data-informed root cause approach to chronic symptoms, evaluating the body as an interconnected system instead of a collection of isolated complaints. The methodology below is the framework behind every engagement with Yelena Tselenchuk, BCDHH.
Key Takeaways
- Step 1 - Investigate: Gather the full picture through a comprehensive intake, TCM observational review, and targeted functional testing before any recommendations are made.
- Step 2 - Interpret and Prioritize: Translate complex results into clear findings, pattern recognition across systems, and a prioritized sequence.
- Step 3 - Recommend and Strategize: Personalized, data-informed recommendations sequenced to what your body can actually handle right now.
- Step 4 - Support and Refine: Ongoing reassessment that builds on prior work instead of starting over.
That is not a failure of effort. It is a gap in investigation.
Why Investigation Matters
Conventional care typically assigns one specialist per symptom. Your fatigue goes to one provider. Your digestive issues go to another. Your hormone concerns go to a third. Each evaluates in isolation, and the connections between systems are never explored. The result is a familiar pattern: several rounds of "your labs look normal," a label, a prescription, and a quality of life that continues to decline.
Where conventional evaluation asks "is there disease?", this whole body health assessment asks a different question: where is function declining, and what's driving it? That shift is what the four-step methodology below is built to answer.
Step 1 - Investigate: Gathering the Complete Picture
Every engagement begins with investigation, a thorough, system-wide effort to understand what's happening in your body before any recommendations are made. This isn't a quick intake form and a 15-minute conversation.
Comprehensive intake questionnaire
Before your first live session, you complete a detailed questionnaire covering full health and symptom history, diet and digestion, lifestyle and sleep, stress load, prior testing, and a timeline of when symptoms began or shifted. It creates a system-wide symptom map, not a single-complaint intake.
Traditional Chinese Medicine observational review
You submit photos for assessment of the face, tongue, eyes (iridology), and nails. These observations add a layer of pattern recognition that lab work alone cannot provide.
Several hours of practitioner preparation
Yelena reviews your complete intake, cross-references symptoms with your observational review, and identifies the areas that require deeper attention. The investigation begins well before the video call.
Targeted functional testing when appropriate
Tests are chosen based on what your intake reveals, spanning gut health, nutrient status, hormone signaling, detox capacity, and stress physiology. Every test is selected for a reason. Nothing is ordered speculatively.
Why it matters: Recommendations made without data are opinions. This step replaces guessing with a clear, factual baseline.
Step 2 - Interpret and Prioritize: Making Sense of the Data
Data is only useful when understood in context. Step 2 is where raw results, intake findings, observational patterns, lab values, symptom history, are translated into a coherent picture of what's happening and why.
Labs interpreted in context
Every marker is evaluated alongside your lifestyle, diet, stress, health history, and timing. A value inside a "normal" reference range may still be far from optimal, and in context it often tells a very different story.
Pattern recognition across systems
How gut imbalances affect nutrient absorption, which affects energy and hormone production. How stress physiology drives sleep disruption, which compounds cognitive symptoms. How detox capacity contributes to inflammatory patterns that show up as skin, weight, or immune changes. Siloed evaluations miss these relationships.
Prioritized findings
Not everything that's "off" needs to be addressed at once. You leave this step knowing what to address first, what to address later, and why.
Why it matters: This is where confusion becomes clarity. You stop wondering "what's wrong" and start understanding what your body has been communicating all along.
Step 3 - Recommend and Strategize: A Plan Built on Your Data
With a clear picture and established priorities, the next step is informed action. Recommendations are personalized to your physiology, lifestyle, capacity, and specific findings. There are no generic protocols.
Nutrition adjustments drawn from your lab findings, not generalized meal plans. Lifestyle modifications aligned with what your data shows your body needs. Supplement support selected to address identified gaps, not a long list of "just in case" additions. Where relevant, gut repair strategies and sequenced detox support.
Why it matters: You're not handed a list of 30 changes to make at once. You're given the right interventions in the right order, with enough context to make informed choices about your own body.
Step 4 - Support and Refine: Adjusting as the Body Responds
Root-cause work doesn't end with the first set of recommendations. As your body responds, symptoms shift, capacity improves, and new patterns emerge. The plan has to adapt with them.
Follow-up reassessment
We evaluate which symptoms have shifted and what that tells us about the original findings, whether priorities need reordering, and when the next layer of investigation is appropriate.
Cumulative, not start-over
Every piece of data builds on what came before. Follow-up sessions deepen the investigation rather than restarting it. When something changes, it's understood in the context of everything that's already been examined.
Steady momentum over straight-line progress
Some weeks bring noticeable improvement. Others feel slower. What matters is direction, and this step is what keeps you moving in one.
Why it matters: Many women who come to Functional Root have already cycled through multiple providers, each starting from scratch. This step prevents that cycle.
What Sets This Approach Apart
The methodology above may sound different from what you've experienced in conventional care or other wellness settings. That difference is intentional.
Whole-body investigation, not siloed care
Every symptom is evaluated as part of a connected whole. Lab data is assessed alongside lifestyle, diet, stress, history, and timing. Full context reveals patterns that fragmented care can't.
Facts with context, not numbers without meaning
A thyroid marker in the "normal" range means something different for a woman sleeping eight hours and feeling rested than for one sleeping eight hours and waking exhausted. Context determines meaning.
Root-cause investigation, not symptom management
The focus is on what's driving symptoms across systems, not how to suppress them. Unresolved patterns tend to progress.
Sequencing matters
Detox, gut repair, and hormonal support only work when the body is ready to respond. Introducing them too early can worsen symptoms.
Clarity before action
You understand what's happening and why before any protocol begins. No list of changes without the rationale behind them.
Agency, not dependency
The goal isn't a practitioner-for-life relationship. It's helping you understand your body clearly enough to make confident decisions, with guidance when you need it and independence when you're ready.
Who This Is For
This methodology is built for women who have been told their labs are "normal" but still feel far from fine, who are tired of guessing, and who want a structured investigation instead of another round of symptom management. It works best when you're willing to engage with the intake process, sit with the data, and move through recommendations in sequence.
It's probably not the right fit if you're looking for a quick fix, a single supplement recommendation, or a protocol that skips the investigation. Root-cause work is thorough by design, because meaningful clarity requires comprehensive data and careful analysis.
What Patients Say
Frequently Asked Questions
What should I expect before my first naturopathic session?
Before your first session, you complete a comprehensive intake questionnaire covering your full health and symptom history, diet, lifestyle, stress patterns, and prior testing. You also submit photos for a Traditional Chinese Medicine observational review. Yelena then spends several hours reviewing your intake and mapping symptom patterns across body systems before you ever meet live. Your first session begins with a detailed foundation already in place, so the conversation focuses on connecting patterns and identifying priorities rather than starting from scratch.
How long does the investigation process take?
The timeline varies based on symptom complexity and scope of testing. An initial session is typically scheduled within one to two weeks of completing intake. When functional lab testing is recommended, most at-home collection kits arrive within a few days, and results are typically available within two to four weeks. The full investigation, from first session through initial interpretation and recommendations, generally spans four to eight weeks. Follow-up refinement is scheduled based on individual progress.
Do I need to do lab testing?
Functional lab testing isn't required for every engagement, but it's frequently recommended because it provides measurable data that strengthens the investigation. Standard blood panels use broad reference ranges designed to identify disease, not declining function. Functional testing evaluates areas that standard panels often miss: gut microbiome balance, nutrient deficiencies, hormone patterns, detox capacity, and metabolic markers. Whether testing is appropriate for your situation is discussed during the initial consultation or first session.
How is this different from what my primary care doctor does?
Primary care is designed to identify and manage disease. This methodology is designed to identify and address functional imbalance before it progresses, using a wider set of tools (functional labs, TCM observational review, systems-level pattern recognition) and interpreting results in the context of your daily life. It's a complement to conventional care, not a replacement.
Is the whole process virtual?
Yes. Functional Root is 100% virtual. Intake is completed online, sessions are conducted over Zoom, and functional testing uses at-home collection kits shipped directly by the laboratory. Blood draws, when needed, are scheduled at a local lab near you (available in all states except New York).
Ready to Begin Your Investigation?
If you've spent months or years searching for answers that never came, or you've been told your labs are "normal" while your quality of life keeps declining, this is a different path forward. The free naturopathic consultation is a 15-minute conversation to understand where you are, what you've been experiencing, and whether Functional Root is the right fit. No sales pitch. Just clarity on your options and an honest recommendation for where to start.
