Chronic diseases have become a leading cause of death and disability worldwide. Non-communicable diseases such as heart disease, cancer, and diabetes cause 41 million deaths each year, accounting for 74% of all deaths worldwide.1 In the United States, these conditions account for eight of the top ten causes of death.2
The transition from communicable diseases to chronic, non-communicable diseases began in the early 1900s, driven by advances in hygiene, nutrition, and medical technology. But this transition came with its own challenges. The prevalence of chronic diseases continues to increase due to the aging population and changes in lifestyle.
The cost to the healthcare system is enormous. In the U.S. alone, it amounts to over $1 trillion annually.3 Fortunately, there are many steps you can take to lower your risk and prevent chronic disease. Understanding effective prevention strategies is essential to improving overall health and well-being.
Big Four: Heart Disease, Cancer, Diabetes and Dementia
Among chronic diseases, four are particularly impactful: heart disease, cancer, diabetes, and dementia. Heart disease remains the leading cause of death in the United States, followed closely by cancer, claiming more than 600,000 lives each year. Diabetes affects more than 37 million Americans, and millions more are undiagnosed or have prediabetes.4
Concern about Alzheimer’s disease and other forms of dementia is growing rapidly, currently affecting an estimated 6.7 million Americans over the age of 65. Not only do these conditions affect your health and longevity, but they also place a huge financial burden on individuals and the healthcare system.
The global cost of cancer is expected to reach $25 trillion between 2020 and 2050, covering five cancers (tracheal, bronchial, and lung); colon and rectum; chest; Liver and leukemia – account for almost half of the costs.5 As these diseases become increasingly prevalent, prevention and early intervention are important to protect health and quality of life.
Most Americans suffer from a chronic illness.
Nearly 60% of American adults have at least one chronic disease. Approximately 40% suffer from multiple chronic diseases.6 A recent study published in Frontiers in Public Health predicted a significant increase in chronic diseases among adults aged 50 and older.7
By 2050, the number of Americans in this age group is expected to increase by 61%, reaching 221 million. Additionally, the number of people living with one or more chronic conditions is expected to increase by 99.5%, from 71.5 million in 2020 to 142.7 million in 2050.8
Researchers considered nine major chronic diseases, including high blood pressure, diabetes, cancer, chronic lung disease, heart disease, stroke, arthritis and mental illness. These predictions highlight the urgent need to take proactive steps in managing our health, as the likelihood of developing chronic diseases increases with age.
Increase in multimorbidity: Growing interest in health
While the rise in single chronic conditions is a concern, the rise in multimorbidity – having two or more chronic conditions – is equally concerning. The study predicts that multimorbidity cases will increase 91.1% from 7.8 million in 2020 to 14.9 million in 2050.9
The majority of patients with chronic illness or multimorbidity are between the ages of 60 and 79. However, from 2020 to 2050, single chronic diseases are expected to increase by 244% and complex diseases by 202.7%, with the population aged 80 and older expected to increase the most.10
This study also reveals interesting patterns in the distribution of chronic diseases by gender and race. By 2050, women are expected to make up 53% of patients with a single chronic disease, while men are expected to make up the majority (51%) of patients with multimorbidity. Among racial groups, non-Hispanic whites are expected to see the largest increase in absolute numbers, but other racial groups will also experience significant increases.
For example, the number of Hispanics with at least one chronic disease is expected to increase 110% from 2020 to 2050. These gaps highlight the need for targeted health interventions and tailored approaches to chronic disease prevention and management.
Understanding your risk factors based on your gender and ethnic background can help you take more effective steps to prevent chronic disease. However, adopting a holistic approach that addresses the root cause of the disease, not just individual symptoms, is essential for everyone at all stages of life.
Geographic patterns of chronic disease
Your risk of chronic disease is not only influenced by individual factors, but is also closely linked to where you live. A study published in Preventing Chronic Disease revealed geographic patterns in chronic disease prevalence across the United States.11
The southeastern region of the country stands out as a hotspot with populations with a high overall prevalence of chronic diseases. This pattern is not random. This reflects decades of social and economic policies that have created an environment conducive to poor health outcomes.
In contrast, areas with low chronic disease prevalence are more dispersed, often clustered around major metropolitan areas. For example, in Texas, low-incidence areas can be found around Dallas, Houston, Austin, and San Antonio. Likewise, the Atlanta metropolitan area in Georgia has a lower incidence of chronic diseases compared to surrounding areas.
Areas with high prevalence of chronic diseases often share common socioeconomic characteristics. If you live in these areas, you are more likely to have higher rates of disability, unemployment, and increased dependence on government assistance programs like SNAP. Education level is also an important factor. In areas with low chronic disease prevalence, the percentage of residents with post-secondary education is much higher.
The economic disparities are stark. Median income in areas with the lowest prevalence of chronic diseases is almost twice that of areas with the highest prevalence. Home values show an even more dramatic difference. The median in low-prevalence areas is almost three times higher than in high-prevalence areas.12
These disparities highlight the significant impact that local environment and community characteristics have on health. But remember, along with being aware of the risks associated with your location, it’s also important to take proactive steps to mitigate them.
Mental Health Crisis: A Hidden Epidemic Amid the Chronic Disease Pandemic
While physical chronic conditions are at the forefront of health discussions, mental health disorders are quickly becoming a significant part of the global burden of disease. Mental health problems account for 20% of the global burden of disease;13 Addiction, mood disorders and anxiety play a major role.
There are often delays in receiving treatment for these conditions. For example, obsessive-compulsive disorder (OCD), one of the top 10 causes of disability in developed countries, typically goes untreated for about 10 years. Likewise, people with gambling disorder often wait around nine years before getting help.
These delays significantly increase the burden of disease. Because mental and physical health are deeply interconnected, recognizing the importance of mental health in your overall well-being is critical to your health journey.
Addressing the 4 E’s to prevent premature death from chronic disease
Optimizing your mitochondrial health is the most important step you can take to achieve vibrant, lasting health and prevent chronic disease. Because impaired mitochondrial function is at the core of most chronic diseases.
There are approximately 100,000 trillion mitochondria in our bodies.14 Each has hundreds of electron transport chains. Their sheer numbers show how important they are to cellular function as well as overall well-being. Mitochondria produce adenosine triphosphate (ATP), which is important for all body functions. Without energy, cells cannot repair and regenerate themselves.
The underlying problem in most chronic diseases is that cells do not produce enough energy. There are four main factors that reduce cellular energy production: the four E’s.
1. Excess essential fats (seed oils) — Excessive consumption of processed seed oils, which are common in modern diets, especially processed foods, poses serious health risks. Rich in linoleic acid (LA), this oil has profound effects on mitochondrial function.
2. Estrogen — Estrogen increases intracellular calcium levels and reduces mitochondrial function. In fact, estrogen dominance is just as dangerous as excessive LA intake in disrupting mitochondrial function.
It is important to minimize exposure to synthetic estrogens found in hormone replacement therapy and oral contraceptives. Xenoestrogens, found in everyday items such as plastics, are another widespread source of exposure.
3. Electromagnetic fields (EMF) – A third significant threat to cellular health is increased exposure to EMFs due to the proliferation of wireless technologies. EMF increases the concentration of calcium ions within cells, producing harmful free radicals.
4. Endocrine disrupting chemicals (EDCs) — EDCs refer to a wide range of substances, including plastics, that disrupt hormonal function and have been linked to a variety of health problems, including reproductive problems, developmental disorders and certain cancers.
These chemicals primarily work by activating estrogen receptors on cells, similar to the way EMFs activate voltage-gated calcium channels. This activation increases calcium influx into cells, and excess intracellular calcium dramatically increases superoxide and nitric oxide. They combine quickly to form peroxynitrite, a very powerful oxidative stressor. This causes severe oxidative stress and cell damage.
Strengthen cellular health by avoiding mitochondrial toxicity
These and other mitochondrial toxins disrupt the delicate oxygen balance in the gut, creating an environment that promotes the growth of harmful oxygen-tolerant microorganisms while simultaneously inhibiting the growth of beneficial, oxygen-tolerant microorganisms that are important to gut health. Mucin acts as a binding agent for the colonic epithelium and colon cells form an important barrier.
Damage to this barrier leads to a gradual decline in health and accelerated aging process.
Addressing the underlying factors that damage colon cells and restoring adequate oxygen levels are essential to rebuilding populations of beneficial oxygen-intolerant microorganisms. Communication between mitochondria and the gut microbiome is very important. However, when oxygen-resistant pathogenic bacteria dominate, they crowd out beneficial bacteria and prevent the production of metabolites needed for optimal health.
Until excess oxygen is removed from the colon, even the most beneficial lifestyle factors such as exercise, sleep, nutrition, and supplements may not provide significant improvement. Simply introducing probiotics is not an effective solution. This is because commercially available probiotics often cannot survive in the intestinal environment. While this may provide postbiotic benefits, it cannot serve as a true “seed” for rebuilding a proper microbiome.
Just as seeds need the right conditions to grow, oxygen-intolerant microorganisms need a healthy intestinal environment to thrive. Avoiding mitochondrial toxicity, such as the above, is important for creating and maintaining a favorable environment for gut health and microbial balance, and ultimately preventing chronic disease.
My new book, “A Guide to Cellular Health: Unlocking the Science of Longevity and Joy,” details how to improve mitochondrial function for increased cellular energy. Addressing energy production could prevent the majority of premature deaths from chronic diseases globally.
