In this episode of Sixty Plus Uncensored, host Sebastian Frey speaks with functional medicine physician Dr. David Bilstrom about why so many people today feel chronically tired, inflamed, stressed, and unhealthy despite living in a time with more advanced medical technology than ever before. Rather than viewing chronic illness as a collection of separate symptoms requiring separate medications, Dr. Bilstrom presents a broader perspective focused on inflammation, gut health, hormone balance, stress, and the body’s natural ability to heal when underlying imbalances are properly addressed. Throughout the conversation, he repeatedly emphasizes that the body is not designed to constantly work against itself and that many modern health problems, whether they involve digestion, sleep, hormones, energy levels, cognition, blood vessels, or chronic pain, are often connected through deeper inflammatory and metabolic processes. What makes the discussion especially compelling is that Dr. Bilstrom does not frame health as something achieved through quick fixes, extreme discipline, or miracle supplements. Instead, he encourages a more thoughtful approach centered on understanding why the body became imbalanced in the first place and then creating conditions that support recovery, resilience, and long-term health. While the conversation explores topics ranging from autoimmune disease and cortisol to gut dysfunction, low testosterone, nutrient deficiencies, sleep, and longevity, the larger message remains remarkably hopeful: many people may be far more capable of improving their health than they have been led to believe.
Why Chronic Disease Has Become So Common
Early in the conversation, Dr. David Bilstrom explains that one of the most significant health challenges today is the dramatic rise in chronic disease. According to him, people are now experiencing serious health problems in their 20s and 30s that previous generations often did not encounter until much later in life. While modern medicine has become extraordinarily effective at handling emergencies, acute illness, trauma, and life-saving interventions, he believes it has been far less successful at addressing the deeper root causes of chronic conditions that gradually develop over years or even decades. In his view, many people are living longer than previous generations, but not necessarily healthier, and that distinction becomes an important theme throughout the interview.
Dr. Bilstrom points to the modern environment as a major factor contributing to this growing health crisis. Throughout the discussion, Seb describes modern life as a kind of “toxic soup” filled with processed foods, pesticides, plastics, environmental chemicals, chronic stress, poor sleep habits, antibiotics, overstimulation, and constant exposure to inflammatory triggers. Dr. Bilstrom largely agrees with that characterization, explaining that many aspects of modern life place ongoing stress on the immune system and contribute to chronic inflammation throughout the body. According to him, the body is often asked to adapt to conditions it was never designed to handle continuously over long periods of time.
Importantly, Dr. Bilstrom clarifies that inflammation itself is not inherently harmful. Inflammation is actually a normal and necessary part of the body’s immune response. The body uses inflammation to fight infections, eliminate damaged cells, and protect itself from injury or harmful invaders. Problems begin when inflammation becomes excessive, chronic, or is unable to properly shut off. Instead of resolving naturally after a threat passes, the immune system can remain activated for long periods of time, gradually contributing to tissue damage, metabolic dysfunction, and chronic disease.
According to Dr. Bilstrom, excessive inflammation is connected to many of the most common health conditions people face today, including cardiovascular disease, diabetes, arthritis, autoimmune disorders, chronic fatigue, cognitive decline, digestive dysfunction, and hormone imbalance. While these conditions may appear unrelated on the surface, he believes inflammation often acts as a shared underlying driver linking them together. That perspective becomes one of the central themes throughout the entire conversation: many chronic illnesses may not be isolated problems at all, but rather different expressions of deeper systemic imbalance occurring throughout the body over time.

Understanding Inflammation Beyond the Buzzword
The term “inflammation” has become so common in modern health conversations that many people hear it constantly without fully understanding what it actually means. Throughout the interview, Dr. David Bilstrom spends considerable time explaining that inflammation is not a disease by itself, but rather a biological process that can either protect the body or, when dysregulated, gradually contribute to chronic illness. Under normal conditions, inflammation is essential for survival. When the immune system encounters a virus, harmful bacteria, injury, or toxin, it creates inflammation as part of the body’s defense and healing response. In those situations, inflammation is protective and necessary. Problems begin when the body becomes stuck in a prolonged inflammatory state where the same immune mechanisms that normally help us recover remain activated for too long and begin contributing to ongoing damage instead.
One of the more interesting aspects of the discussion is the way Dr. Bilstrom connects inflammation across multiple body systems rather than viewing it as isolated to one condition or organ. He explains that the “itis” at the end of many medical diagnoses literally refers to inflammation. Arthritis means inflammation of the joints. Tendonitis refers to inflammation of tendons. Colitis refers to inflammation in the colon. Although the affected body part changes, the underlying inflammatory process remains remarkably similar. In his view, this highlights how many seemingly unrelated conditions may actually share deeper biological mechanisms connected to immune dysfunction and chronic inflammation.
Dr. Bilstrom also emphasizes that inflammation does not always create immediate or obvious symptoms. Some organs “complain” loudly through pain, stiffness, swelling, or discomfort, while others can remain relatively silent for years before problems become noticeable. Joint inflammation may quickly get someone’s attention because it causes pain and reduced mobility, but inflammation inside blood vessels, organs, or metabolic systems may progress quietly over long periods of time without obvious warning signs. This becomes especially important when discussing cardiovascular disease. Many people think of heart disease primarily in terms of cholesterol, but Dr. Bilstrom argues that inflammation inside blood vessels plays a central role in the hardening and narrowing of arteries that eventually contribute to cardiovascular problems.
The broader point he repeatedly returns to is that inflammation in one area of the body often suggests broader systemic inflammation elsewhere. Someone struggling with chronic joint pain, digestive discomfort, skin issues, fatigue, or hormone imbalance may also have inflammatory processes affecting metabolism, blood vessels, immune function, or brain health, even if those problems have not yet fully surfaced. Throughout the interview, Dr. Bilstrom encourages listeners to think about inflammation not as a single symptom or diagnosis, but as a larger underlying process that may connect many different aspects of long-term health and aging.
The Gut as a Central Control System
One of the strongest themes throughout the interview is the importance of gut health and the central role it plays in overall wellness. Dr. David Bilstrom repeatedly describes the gut as one of the body’s foundational systems, explaining that its influence extends far beyond digestion alone. According to him, approximately 80% of the immune system surrounds the digestive tract, which means disruptions within the gut can strongly affect inflammation, immune regulation, hormone balance, metabolism, and even mental and emotional health. Throughout the conversation, he presents the body as a highly interconnected system, and the gut becomes one of the clearest examples of that interconnectedness in action.
A major focus of the discussion is the intestinal microbiome, the ecosystem of bacteria and microorganisms living inside the digestive tract. Dr. Bilstrom explains that many aspects of modern life can gradually damage the balance between beneficial and harmful bacteria within the microbiome. Processed foods, chronic stress, antibiotics, environmental toxins, poor sleep, nutrient deficiencies, and long-term inflammation may all contribute to microbiome disruption over time. When that balance becomes unhealthy, inflammation throughout the body often increases as well. In Dr. Bilstrom’s view, many chronic diseases may be linked, at least in part, to dysfunction within the gut and the microbiome, even when symptoms appear in completely different areas of the body.
The conversation also explores the growing body of research surrounding what scientists refer to as the “gut-brain axis.” While many people have heard the gut described as the body’s “second brain,” Dr. Bilstrom expands on that idea by explaining that researchers are now studying gut connections not only to mental health, but also to the skin, immune system, hormones, metabolism, cardiovascular health, and other major systems throughout the body. In his view, improving gut health may positively influence much more than digestion alone. It may also affect inflammation levels, energy, mood, sleep quality, hormone regulation, cognitive clarity, and long-term disease prevention. Throughout the interview, he consistently encourages listeners to think about health more holistically rather than viewing symptoms as isolated problems disconnected from one another.
Why Stress and Cortisol Matter So Much
Another major topic throughout the conversation is chronic stress and the hormone cortisol. Seb openly discusses his own experiences with poor sleep, ongoing work pressure, mental exhaustion, and feeling constantly overwhelmed by responsibilities, which leads to a broader discussion about how modern stress affects long-term health. Dr. David Bilstrom explains that while cortisol is often labeled as a “bad” hormone, the reality is much more complex and nuanced. In fact, cortisol is essential for survival. According to Dr. Bilstrom, it is one of the few hormones people literally cannot live without because it plays a critical role in regulating inflammation, energy production, immune function, and the body’s overall stress response.
The problem, he explains, is not cortisol itself but rather the body becoming trapped in a prolonged state of stress where cortisol regulation becomes disrupted over time. Under healthy conditions, cortisol follows a natural circadian rhythm. Levels should be highest in the morning to help people wake up feeling alert and energized, then gradually decline throughout the day before reaching their lowest point at night to support rest and recovery. Chronic stress, however, can interfere with that rhythm in significant ways. According to Dr. Bilstrom, both emotional and physical stress contribute to the problem. Emotional stress may come from work pressure, anxiety, caregiving responsibilities, financial strain, lack of rest, or ongoing mental overwhelm. Physical stress can come from nutrient deficiencies, chronic inflammation, poor gut health, infections, toxin exposure, sleep disruption, or hormone imbalance.
Over time, the nervous system can become stuck in a constant stress response where cortisol remains chronically dysregulated. Some people begin feeling exhausted in the morning but unusually wired or restless at night. Others may experience anxiety, poor sleep, digestive issues, irritability, brain fog, chronic tension, or difficulty recovering physically and emotionally. One of the more helpful distinctions Dr. Bilstrom makes is that the body is designed to handle temporary stress, not constant stress. A short burst of cortisol during a dangerous or demanding situation is protective and useful. The problem arises when the nervous system never fully returns to a calm and regulated state. When stress remains continuous for months or years, the effects often begin accumulating throughout multiple body systems.
Dr. Bilstrom also emphasizes that chronic stress affects far more than mood alone. In his view, long-term stress becomes deeply intertwined with many major chronic health conditions because it influences digestion, inflammation, hormone production, blood sugar regulation, immune function, sleep quality, and metabolic health all at the same time. That interconnected perspective becomes a recurring theme throughout the interview. Rather than viewing stress as simply an emotional issue, he presents it as a full-body physiological burden that can gradually disrupt nearly every foundational system involved in long-term health and aging.

Low Testosterone and Modern Hormone Imbalance
Hormone balance becomes another important focus during the interview, particularly when Seb discusses his own bloodwork showing elevated LDL cholesterol and low testosterone levels. This personal example opens the door to a broader conversation about how increasingly common hormone imbalance has become, especially among men. Dr. Bilstrom explains that low testosterone is now appearing in men at much younger ages than many people realize. In his view, this trend is closely connected to modern lifestyle and environmental factors, including chronic stress, poor sleep, nutrient deficiencies, toxin exposure, inflammation, disrupted gut health, sedentary behavior, and ongoing physical and emotional strain. Rather than seeing hormone imbalance as an isolated issue, he believes it often reflects larger dysfunctions happening throughout the body.
One of the more interesting parts of the discussion centers around cholesterol and its role in hormone production. Dr. Bilstrom challenges the common belief that LDL cholesterol is simply “bad” and explains that cholesterol actually serves as one of the body’s foundational building blocks for hormone synthesis. According to him, the body uses cholesterol to produce testosterone, estrogen, progesterone, cortisol, DHEA, and several other important hormones. Because of that relationship, he suggests that elevated LDL levels may sometimes represent the body attempting to compensate for hormone deficiencies, chronic stress, or other underlying imbalances. Rather than looking at cholesterol in isolation, he encourages a more nuanced understanding of how different systems within the body interact with one another.
The conversation also explores how nutrient deficiencies and gut dysfunction may interfere with healthy testosterone production and hormone regulation. Dr. Bilstrom discusses the possible roles of zinc deficiency, iron dysregulation, poor detoxification pathways, chronic inflammation, stress, and microbiome disruption in contributing to hormonal imbalance over time. Throughout this portion of the interview, he consistently pushes back against the idea of isolated “quick fixes.” Instead of simply prescribing hormone replacement therapy immediately, he prefers investigating why the body may be struggling to regulate hormones naturally in the first place. That philosophy reflects one of the larger themes running throughout the entire conversation: symptoms are often connected to deeper biological mechanisms that deserve attention rather than temporary suppression alone.
The Difference Between Normal and Common
One of the most thought-provoking ideas Dr. David Bilstrom returns to repeatedly throughout the conversation is the distinction between what is common and what is truly normal. Conditions such as obesity, diabetes, chronic fatigue, poor sleep, arthritis, cardiovascular disease, hormone imbalance, digestive dysfunction, and cognitive decline have become so widespread in modern society that many people now assume they are simply inevitable parts of aging. Dr. Bilstrom strongly challenges that assumption. In his view, just because a condition has become common does not automatically mean it is biologically normal or unavoidable. He believes many chronic illnesses that are now considered “typical” may actually reflect long-term dysfunction within the body rather than natural aging alone.
Throughout the discussion, Dr. Bilstrom repeatedly emphasizes that chronic conditions usually develop gradually over years or even decades. By the time symptoms become obvious enough for someone to seek medical help, the body may already have been struggling with inflammation, nutrient deficiencies, stress, poor sleep, metabolic dysfunction, hormonal imbalance, and gut disruption for a very long time. In many cases, symptoms such as fatigue, brain fog, joint pain, digestive discomfort, anxiety, poor recovery, or low energy are not isolated problems at all. Instead, he sees them as early warning signs that deeper systems within the body may already be under strain.
This perspective significantly shapes the way Dr. Bilstrom approaches both prevention and treatment. Rather than waiting until a serious disease fully develops, he believes people should begin identifying and addressing imbalances much earlier whenever possible. According to him, the same underlying processes contributing to current symptoms are often the very same processes that may later contribute to cardiovascular disease, diabetes, dementia, autoimmune disorders, mobility decline, or accelerated aging. Someone struggling with poor sleep, chronic stress, digestive issues, inflammation, or hormone imbalance in their 50s may already be experiencing patterns that influence long-term health outcomes decades later.
For that reason, Dr. Bilstrom places strong emphasis on prevention, resilience, and long-term health span rather than simply extending lifespan alone. His broader message throughout the interview is that people should not automatically normalize feeling exhausted, inflamed, mentally foggy, or physically limited simply because those experiences have become widespread. Instead, he encourages listeners to become more curious about the deeper factors shaping their health and to recognize that earlier intervention, lifestyle changes, and better foundational support may significantly influence both how they feel today and how they age over time.
This conversation also connects closely with Why a Growth Mindset Matters at Any Age, which explores how many assumptions people hold about aging, decline, and limitations may deserve to be challenged.
Why Health Span Matters More Than Longevity Alone
Toward the latter part of the interview, the conversation shifts toward aging, mobility, and long-term quality of life. Seb speaks openly about watching his parents struggle with mobility limitations in their 80s and reflects on how emotionally difficult it can be to see aging parents gradually lose physical confidence and independence. That personal moment becomes the foundation for a broader discussion about what healthy aging actually means. Rather than focusing only on how long people live, Dr. David Bilstrom emphasizes the importance of preserving the quality of life throughout the aging process. In his view, extending lifespan alone is not a meaningful goal if people are unable to remain mentally sharp, emotionally engaged, physically mobile, and socially connected as they grow older.
This concept, often referred to as “health span”, becomes central to Dr. Bilstrom’s overall philosophy. Throughout the conversation, he repeatedly emphasizes that the body is often far more adaptable and resilient than many people assume. While he fully acknowledges that aging naturally brings changes, he does not believe severe decline should automatically be accepted as inevitable or untouchable. Instead, he argues that many aspects of poor aging outcomes may be influenced by decades of chronic inflammation, stress, metabolic dysfunction, hormone imbalance, poor sleep, sedentary habits, nutritional deficiencies, and long-term disruption within the body’s foundational systems. In other words, many of the problems commonly associated with aging may not come from age alone, but from accumulated imbalances that develop gradually over time.
Importantly, Dr. Bilstrom’s perspective is not built on unrealistic promises or denial of aging itself. He does not suggest people can completely avoid every physical challenge or health condition later in life. Rather, he encourages people to focus on creating conditions that support resilience, recovery, and healthier function for as long as possible. That includes improving sleep quality, reducing chronic stress, supporting gut health, correcting nutrient deficiencies, maintaining movement and muscle mass, supporting hormone balance, and paying closer attention to emotional well-being. Throughout the interview, he presents healthy aging not as a miracle outcome or a matter of perfection, but as the result of consistently supporting the body’s interconnected systems over time. His message ultimately feels hopeful because it shifts the conversation away from fear and resignation and toward the idea that many people may still have more influence over their long-term health and quality of life than they realize.
The Foundational Triad: Vitamin D, Probiotics, and Butyrate
One of the most practical and memorable parts of the interview centers around what Dr. Bilstrom calls the “foundational triad.” According to him, three particular elements play especially important roles in supporting gut health, regulating the immune system, and reducing chronic inflammation throughout the body: vitamin D, probiotics, and butyrate. While each serves a different function, Dr. Bilstrom believes they work together in ways that may significantly influence overall health and long-term resilience. Throughout the conversation, he repeatedly returns to the idea that many chronic conditions are connected to inflammation and microbiome disruption, making these foundational supports especially important in functional medicine approaches.
Vitamin D becomes a major focus because Dr. Bilstrom believes many people are deficient without realizing it. He explains that standard lab reference ranges are often based on broad population averages rather than what may be truly optimal for long-term health and immune function. As a result, many individuals are told their vitamin D levels are technically “normal” even when those levels may still be suboptimal from a functional health perspective. He also discusses the role of vitamin D receptors in the gut and how dysfunction or resistance at those receptors may contribute to inflammation, immune imbalance, and microbiome disruption over time. In his view, vitamin D influences far more than bone health alone and may play a meaningful role in immune regulation, mood, inflammation control, and overall metabolic function.
Probiotics become another important piece of the discussion. Dr. Bilstrom describes probiotics as beneficial bacteria that help restore balance within the gut microbiome, especially after years of stress, poor diet, antibiotics, environmental toxins, and other lifestyle disruptions. Because the gut and immune system are so closely connected, he believes supporting healthy bacterial balance may positively influence digestion, inflammation, hormone regulation, and even cognitive and emotional health. The broader point he emphasizes is that many people spend years unintentionally damaging the microbiome without realizing how deeply it may affect the rest of the body.
The third element, butyrate, is less familiar to many listeners but becomes one of the most fascinating topics in the conversation. Butyrate is a short-chain fatty acid naturally produced by healthy gut bacteria, particularly when those bacteria ferment certain types of dietary fiber. According to Dr. Bilstrom, butyrate plays a major role in reducing inflammation, supporting the integrity of the gut lining, regulating immune responses, and influencing cellular health. He also discusses butyrate’s role in “epigenetics,” meaning it may help influence how certain genes are expressed, potentially turning down harmful inflammatory pathways while supporting healthier cellular function. Whether or not listeners fully agree with every scientific claim discussed, the larger message remains consistent throughout the episode: gut health appears deeply connected to overall health in ways modern medicine is still actively learning to understand.
Moving Beyond “One Pill for One Ill”
One of Dr. David Bilstrom’s strongest criticisms of conventional healthcare is what he calls the “one pill for one ill” approach. In his view, modern medicine often treats symptoms individually rather than looking at how different systems throughout the body influence one another. As a result, someone may end up taking one medication for cholesterol, another for sleep, another for anxiety, another for blood pressure, another for blood sugar, and another for joint pain without ever addressing the larger inflammatory or metabolic patterns connecting those problems. Over time, this fragmented approach can leave people feeling discouraged, overwhelmed, and frustrated because they may still feel unwell despite managing multiple symptoms separately.
Rather than focusing only on symptom suppression, Dr. Bilstrom believes healthcare should also ask a deeper question: why did the body become imbalanced in the first place? Importantly, he is not arguing that conventional medicine has no value or that medications should never be used. Instead, he encourages a more comprehensive approach that combines symptom management with a deeper investigation into root causes. Throughout the conversation, he repeatedly emphasizes that the body functions as a highly interconnected system. Gut health, inflammation, hormone balance, stress, sleep, nutrition, immune function, and metabolism all influence one another in complex ways. Because of that connection, improving one foundational system may positively affect many seemingly unrelated symptoms at the same time.
This philosophy becomes especially important when discussing prevention and long-term quality of life. Rather than waiting until a major disease develops, Dr. Bilstrom encourages people to identify and address imbalances as early as possible. In his view, symptoms like fatigue, poor sleep, digestive problems, chronic stress, inflammation, or low energy are often signals that the body is struggling long before more serious conditions appear. By paying attention to those early warning signs and supporting the body more proactively, he believes many people may be able to improve not only how they feel today, but also their long-term health, mobility, cognition, and resilience as they age.

A More Hopeful View of Aging and Health
By the end of the conversation, one message becomes especially clear: Dr. David Bilstrom believes many people underestimate the body’s capacity to adapt, recover, and improve over time. While he fully acknowledges the realities of aging, chronic stress, and the challenges of modern life, his perspective remains fundamentally hopeful rather than fearful. He does not present health as something achieved through perfection, extreme discipline, rigid routines, or constant self-optimization. Instead, he repeatedly emphasizes the importance of consistency, awareness, and supporting the body’s foundational systems in a sustainable way. Throughout the discussion, he explains how different aspects of health are deeply interconnected; gut health, sleep quality, stress management, hormone balance, nutrition, movement, and emotional well-being all influence one another in meaningful ways. In his view, the body is often working continuously to heal and rebalance itself when given the right support and conditions to do so. That perspective feels especially encouraging for older adults and for anyone hoping to preserve energy, mobility, cognition, and long-term quality of life. Rather than accepting chronic illness, exhaustion, or physical decline as inevitable, Dr. Bilstrom encourages people to become more curious about the deeper factors shaping their health and to recognize that meaningful improvement may remain possible far longer than they assume.
