KEY DRIVERS OF DISEASE
The key drivers of disease are chronic inflammation, lifestyle factors, environmental and metabolic stress, and cellular dysfunction. These underlying elements produce symptoms, which lead to a diagnosis and subsequent treatment by a health care provider. Understanding each element in detail is essential to shifting away from traditional symptom-based care.
THE NEW HEALTH CARE PARADIGM
In the new health care paradigm, prevention and wellness are primary goals. Instead of relying on the “endless treatment model” that simply manages symptoms, there is a growing focus on identifying and addressing the root causes of disease. By promoting wellness and preventing chronic disease, the health care system can achieve better outcomes for individuals and the community.
DISEASE: WHY TREATING SYMPTOMS IS NOT ENOUGH
The current health care system is structured to treat symptoms rather than prevent the onset of disease. Health and wellness have often been secondary priorities, with short visits, fragmented care and medication-centered solutions dominating medical practice. This approach leaves little room to address crucial factors such as nutrition, stress, environmental exposure and social support.
Many people mistakenly believe that disease begins with a diagnosis of conditions like diabetes, heart disease, depression or autoimmune disorders. Disease often develops years or even decades before a diagnosis is made and treatment is initiated. The focus on chronic disease management and crisis care rarely cures the underlying issues, leading to the prevalence of “comorbidities” and only achieving “remission” or “control” at best.
The health care system falls short by neglecting the complex series of root causes that silently erode health long before individuals become patients. Most chronic diseases are not inevitable. Rather, they result from a combination of biological vulnerability, long-term lifestyle exposures, social and environmental stressors, and delayed intervention by the health care system.
Biological vulnerability + long-term lifestyle exposure + social and environmental stressors + a system that intervenes too late.
This explains why prevention, health literacy, community engagement and early interventions are critical. These principles have been addressed in previous op-eds, emphasizing the need for a community approach, especially through faith and civic organizations.
BIOLOGICAL AND PHYSIOLOGICAL ROOT CAUSES
Chronic diseases such as heart disease, diabetes, respiratory illness, arthritis and dementia have biological roots that originate within the body’s physiological systems. These internal mechanisms cause tissue and organ damage, resulting in low-grade, persistent inflammation. If left unchecked, chronic inflammation develops and leads to the onset of major disease.
Additional influences include poor diet, obesity, stress, infections, toxins and lack of sleep. Insulin resistance and metabolic dysfunction are central to conditions like Type 2 diabetes, fatty liver disease, PCOS and cardiovascular disease, often developing years before diagnosis. Oxidative stress, caused by an excess of free radicals, overwhelms antioxidant defenses and damages DNA and cells, leading to immune dysregulation, either underactive, such as chronic infections and cancer risk, or overactive, such as autoimmune disease and allergies. These processes develop slowly in response to daily exposures, habits and stressors.
LIFESTYLE AND BEHAVIORAL ROOT CAUSES
Lifestyle and behavioral root causes are modifiable, yet they account for the largest burden of disease. Key factors include:
• Poor nutrition: Diets high in ultra-processed foods, excess sugar and refined carbohydrates, low fiber and micronutrient deficiencies directly contribute to metabolic disease, gut dysfunction and inflammation.
• Physical inactivity: Lack of exercise leads to muscle loss, insulin resistance, depression and mental illness.
• Sleep deprivation: Insufficient sleep impairs immune function, hormonal regulation and mental health.
• Chronic stress: Prolonged elevation of cortisol results in hypertension, anxiety, depression, immune suppression and weight gain.
ENVIRONMENTAL ROOT CAUSES: TOXIC EXPOSURES
Exposure to toxins in the environment is a major contributor to disease. Air and water pollution are linked to asthma, COPD, heart disease and cancer. Endocrine-disrupting chemicals found in plastics, pesticides and cosmetics interfere with hormones, affecting fertility and thyroid function and increasing the risks of obesity and cancer. Toxins such as lead, mercury, arsenic and mold can cause neurological damage, chronic fatigue syndromes and immune dysfunction.
SOCIAL DETERMINANTS OF HEALTH ROOT CAUSES
Social determinants are powerful predictors of disease, often outweighing genetic factors. They directly impact people where they live. These include food deserts, unsafe housing and environmental exposure zones. Income and education are strongly related to chronic disease rates, with lower income correlating with higher rates of chronic disease.
Limited access to care, caused by unsafe neighborhoods and lack of transportation, leads to delayed diagnosis and worsens health outcomes. Health inequities often impact generations. Social isolation and lack of community support exacerbate health issues, especially in rural and inner-city areas.
PSYCHOLOGICAL AND EMOTIONAL ROOT CAUSES
Adverse Childhood Experiences are strongly associated with heart disease, substance abuse disorders, autoimmune disease and mental illness. Unresolved trauma affects nervous system regulation, immune response and pain perception. The mind-body connection is a physiological reality, not just a theory.
HEALTH SYSTEM AND CULTURAL DRIVER ROOT CAUSES
The current health care system operates reactively rather than proactively. The sick-care model focuses mainly on treating symptoms and less on the key drivers of disease or the Seven Core Lifestyle Interventions. It also fails to thoroughly address the social determinants of health care.
Polypharmacy is an adverse effect of a medication-centered solution to chronic disease. Prescription medications, supplements and over-the-counter drugs have their own side effects and often interact adversely with each other, sometimes presenting as a new disease. Time-limited provider visits of 10 to 15 minutes make it difficult to address complex root causes, encouraging a focus on symptom management. As a result, more time and resources are spent treating disease rather than improving health and wellness.
THE ROLE OF FAITH AND CIVIC COMMUNITIES
Communities do not need to wait for health care reform to address the root causes of disease and support good health. They can develop health care ministries and committees that offer education on the Seven Core Lifestyle Interventions, which counter many of the root causes of disease.
CONCLUSION: A PARADIGM SHIFT
Transitioning from an endless cycle of disease symptom management to preventive health with a focus on the key drivers of disease is what patients need and want. In fairness to many good health care providers, the trend toward preventive health care is already underway. The reimbursement system needs to catch up to allow providers more time with their patients and less time on administrative functions.
