Sarah's Story, Part 2: Finding the Biological Clues
This is Part 2 of Sarah's story. If you haven't read Part 1, I recommend starting there, where I introduce Sarah and explain how her symptoms led us to investigate her environmental exposures: https://purealternatives.us/blogs/news/plastic-chemicals-in-humans-what-one-patients-laboratory-results-revealed
The Investigation Continues – Following the Biological Clues
When Sarah's Total Tox report came back, I wasn't looking for one smoking gun. Environmental illness rarely works that way. What caught my attention was the overall pattern. Rather than one isolated exposure, her report showed elevated compounds from several completely different categories. Plastic-associated chemicals, pesticide metabolites, heavy metals, and numerous mold toxins were all represented. Together, they painted a picture of a body carrying a substantial toxic burden rather than reacting to a single exposure.

One result stood out immediately. Sarah's BPA level measured 19.25 µg/g, nearly four times higher than the laboratory's upper reference value. Most people recognize BPA as a chemical used in plastics, food can linings, and thermal receipts, but fewer realize how extensively it has been studied. BPA has been associated with altered hormone signaling, oxidative stress, mitochondrial dysfunction, neuroinflammation, and metabolic changes. While no single laboratory value proves that BPA caused Sarah's symptoms, a result this elevated deserves attention as one piece of a much larger biological picture.
The report became even more interesting as we continued reading. Alongside BPA were elevated levels of an organophosphate pesticide metabolite, thallium, multiple aflatoxins, fumonisins, gliotoxin, ochratoxin A, sterigmatocystin, and zearalenone. These compounds come from very different sources. Some are associated with plastics, others with agricultural chemicals, others with environmental molds, and others with metals. Yet despite their different origins, many affect remarkably similar biological pathways. Again and again, research points toward oxidative stress, mitochondrial dysfunction, chronic inflammation, immune dysregulation, and disruption of normal cellular signaling.

The suboptimal levels are not to be dismissed because they fall below the laboratory's cutoff for "high." Individually, these findings may not raise immediate concern. Collectively, they tell us that her body was interacting with a wide variety of environmental chemicals every day.
This is where systems biology becomes so valuable. The body doesn't experience these compounds one at a time. Every cell responds to the total environment surrounding it. Multiple chemicals, each capable of influencing oxidative stress, mitochondrial function, inflammation, hormone signaling, or immune regulation, can converge on many of the same physiological pathways.

The next question practically asks itself. If Sarah was carrying this much environmental burden, why hadn't her body already removed it? We often think about detoxification as something the liver does, but the liver is only one member of a much larger network. Detoxification depends on coordinated communication between the liver, bile, intestines, kidneys, skin, lungs, and one system that receives surprisingly little attention: the lymphatic system.
Unlike the circulatory system, which has the heart to keep blood moving, the lymphatic system has no single pump. Instead, lymph movement depends on several mechanisms working together, including diaphragmatic breathing, skeletal muscle contraction, the rhythmic contraction of the lymphatic vessels themselves, the pulsation of nearby arteries, changes in body position, and a series of one-way valves that keep lymph moving in the proper direction.
One of the most important drivers of lymphatic flow is the diaphragm. Each deep breath creates subtle pressure changes between the chest and abdominal cavities that help draw lymph upward through the thoracic duct before it returns to the bloodstream near the heart.
Every breath does more than move air through the lungs; it also helps move lymph through the body.
Why Does Lymphatic Flow Slow Down?
Like every physiological system, the lymphatic system functions best when the body is healthy, active, and resilient. But because lymph has no dedicated pump capable of overcoming obstacles or compensating for prolonged inactivity, lymph can move more slowly through the tissues.
A number of factors may contribute to reduced lymphatic circulation:
Sedentary lifestyles that reduce normal muscle contractions
Shallow breathing that limits diaphragmatic movement
Previous surgery or scar tissue
Injury or trauma
Chronic inflammation
Restrictions within connective tissues (fascia)
Obesity
Certain medical conditions that affect lymphatic function
The composition of lymph itself can also change. During illness or chronic inflammation, lymph may contain greater amounts of inflammatory proteins, immune cells, cellular debris, and other biological waste. These changes can alter the workload placed on the lymphatic system and influence how efficiently material is transported from the tissues back into circulation.
The result is not that toxins suddenly become "trapped." Rather, the movement of tissue fluid and the substances it carries may become less efficient. From a physiological perspective, this means inflammatory molecules, cellular waste products, and other compounds may remain within tissues longer before reaching the organs responsible for processing and elimination.
This concept is important because it shifts our thinking away from individual organs and toward biological networks. The liver may function normally, the kidneys may filter appropriately, and the intestines may be healthy, yet if the transport system responsible for delivering material to those organs is functioning less efficiently, the overall process of elimination may also become less efficient.
How Do Toxins Reach the Lymphatic System?
Environmental chemicals enter the body through many different routes. We inhale them in polluted air, absorb them through the skin, consume them in food and water, and encounter them through countless everyday products. Mold toxins may be inhaled or ingested. Heavy metals can enter through food, drinking water, occupational exposures, or certain consumer products. Regardless of the source, once these compounds enter the body, they begin interacting with biological systems.
Some remain in the bloodstream only briefly before being metabolized and eliminated. Others enter tissues throughout the body, where they may be transformed, stored temporarily, or gradually released back into circulation over time. Many environmental chemicals are fat-soluble, allowing them to partition into fatty tissue and cell membranes rather than remaining exclusively in the blood.
As these compounds move between the bloodstream and surrounding tissues, they become part of the normal exchange of fluids that occurs throughout the body but each compound has its own chemical properties, preferred routes of metabolism, and methods of elimination. The important point is that the lymphatic system serves as one of the body's major transportation networks, helping move material from the tissues back into circulation where further processing and elimination can occur.

Why We Started with Sarah's Lymphatic System
Sarah's laboratory testing demonstrated a significant environmental burden, including elevated levels of plastic-associated chemicals, multiple mycotoxins, pesticide metabolites, and heavy metals. At the same time, her health history, physical examination, and symptom pattern suggested that her body was struggling to maintain normal physiological balance.
If toxins, inflammatory molecules, and cellular waste products are not moving efficiently from the tissues to the organs responsible for elimination, stimulating detoxification alone may not address the underlying problem. Before increasing the body's workload, it often makes sense to improve the systems responsible for moving material through the body.
That became the starting point.
Our initial focus was not on aggressive detoxification. Instead, we concentrated on improving the body's drainage pathways, supporting healthy lymphatic movement, reducing physiological congestion, and creating a stronger foundation for the body's own detoxification processes. Only after those systems were functioning more effectively did it make sense to increase efforts aimed at mobilizing and eliminating stored environmental chemicals.
This systems-based approach recognizes that detoxification is not a single event or the responsibility of one organ. It is the coordinated work of multiple physiological systems, each depending on the others to function efficiently. By improving transport before increasing elimination, we sought to work with Sarah's biology rather than simply asking it to work harder.
An Unexpected Setback
Over the months that followed, Sarah initially experienced meaningful improvement. Better nutrition, targeted supplementation, and a gradual, systems-based approach appeared to be moving her in the right direction.
Then everything changed.
Rather than continuing to improve, many of her symptoms returned. Sleep became disrupted again. Fatigue increased. Brain fog persisted, and muscle pain worsened despite continuing the program.
This wasn't necessarily a sign that treatment had failed. Sometimes, as stored compounds begin to mobilize, the body's transport and elimination systems simply cannot keep pace.
Instead of pushing detoxification harder, we took a step back.
We shifted our focus to strengthening the body's drainage pathways, supporting healthy lymphatic movement, bowel function, hydration, gentle movement, and the other physiological systems involved in elimination. The goal was not to detoxify faster, but to help her body detoxify more efficiently.
That change in strategy proved to be an important turning point.
Looking Beyond the Laboratory Report
Four months after beginning treatment, we repeated Sarah's Total Tox testing. The results were encouraging. While not every marker improved, many of the compounds that were initially most elevated had declined substantially.

What changed?
While not every marker improved, several of Sarah's most elevated compounds declined substantially during the first four months.

More importantly, her case reinforced a lesson that extends far beyond one patient.
Detoxification is not simply about taking the right supplement or following the latest cleanse. It is a coordinated physiological process involving transport, transformation, and elimination. When one part of that network struggles, the entire system can be affected.
That is why I believe it is so important to ask a different set of questions.
Instead of asking, "What supplement removes this toxin?" we should first ask, "How well are the body's normal transport and elimination systems functioning?"
Those questions often lead us toward the biology that matters most.
Sarah's story is not proof that one protocol works for everyone. Every individual has a unique health history, genetics, lifestyle, and lifetime of environmental exposures. Together, these factors make up what scientists call the exposome—the sum of all the internal and external influences that shape our biology over a lifetime.
Sarah's Story Continues
By now, we had a much clearer understanding of why Sarah had become ill and why we chose the treatment strategy we did. What we didn't know was how her body would respond.
Recovery is rarely a straight line. There were improvements, unexpected setbacks, important discoveries, and moments that completely changed the direction of her care. Those experiences ultimately became some of the most valuable lessons of Sarah's journey.
In Part 3, the final installment of Sarah's story, I'll share what happened over the months that followed; the changes she made, the obstacles she faced, the lessons we learned together, and how a deeper understanding of her biology gradually helped transform her health.
