MITOCHONDRIA: IMPORTANT TO PRACTICALLY EVERY DISEASE PROCESS
Pick a disease… any disease. Chances are, new research is linking that disease process with some aspect of Mitochondrial Dysfunction. How can something so microscopic have such a huge impact? Until recently, they were overlooked and their impact underestimated. Mitochondria work within metabolic pathways that provide the abundance of energy necessary to drive every living process in the human body. Recent research has finally begun to shift from mere evaluation of symptoms to a deeper evaluation of root-causation of those symptoms. In doing so, Mitochondrial function continues to be implicated at an extraordinary level. Think of Mitochondria as being responsible for a literal chain of events that support optimal health. The disease processes that develop are now able to be traced back to the different links in the chain that became impaired or broken. This information is now driving how researchers study disease and how they view potential new treatment and prevention methods for a majority of disease processes we face today.

WHY MITOCHONDRIA ARE BEING LINKED TO SO MANY DISEASES
For complex organisms like humans, ATP-energy is the very currency of life. Without it, we cease to exist. Practically every physiological mechanism performed by our bodies require ATP; from cellular actions, muscular function, nerve and neuron activity and beyond. Ineffective Mitochondrial function (referred to as Mitochondrial Dysfunction) interrupts the sufficient supply of ATP. The devastating effects are only recently being realized.
Mitochondrial Dysfunction and other related Metabolic Dysfunctions are now being linked as a common factor in practically every disease process and the list continues to grow. As is often the case, the true cause of a disease has rarely been understood. But as medical research continues to seek answers past symptomatology, Mitochondria are increasingly being implicated.
Heart disease is an excellent example of how the newfound link to Mitochondria is changing the medical community. A new field of medicine is developing called Metabolic Cardiology. If you come to these physicians symptomatic and in crisis, they initially will likely treat you as any other Cardiologist to address your immediate issue. However, these physicians view cardiac health as being closely related to Mitochondrial health and will have a secondary objective to address and improve overall Mitochondrial function. In fact in adult onset heart disease, some estimates suggest that by the time a patient becomes symptomatic and seeks medical attention, they may have been suffering from Mitochondrial dysfunction for up to 10 to 15 years!
The series of processes involved in cellular respiration and ATP-production can be viewed as a literal “chain” of linked events. As researchers look passed the symptoms and continue to trace back to the source of failure, evidence points toward one or more Mitochondrial links in the chain having been broken or impaired. The link or links broken will determine the disease process that develops. Of course, this can be compounded because as one link is broken, stress to the overall system occurs that can end up affecting other links, triggering additional broken links and further complications. Although creation of reactive oxygen species (ROS), otherwise called oxidative stress, is a normal and natural effect of Mitochondrial function and metabolism, the less efficient Mitochondrial function the higher the level of ROS creation. Reducing oxidative stress (antioxidant therapy, both in the form of antioxidant supplementation and Nrf2 gene activation to increase production of Superoxide Dismutase) has become a primary focus in mediating a majority of chronic and degenerative diseases.
This compounded effect is no more evident than in the process of aging. The biological process of aging is now considered a disease, and the disease process is rooted in both the reduction in the overall quantity of Mitochondria within cells and the decrease in Mitochondrial functional capacity. This new knowledge offers an explanation as to why people seem to age at differing rates; it’s all a matter of how many Mitochondria, how well they function, and how quickly they can recover from damage or effects from toxic exposures (referred to as Mitochondrial DNA Repair Rate).
But the future of medicine is looking bright. As research is being directed toward Mitochondrial dysfunction being the source of disease, more extensive knowledge is being acquired about the complexities of these little organelle and how best we can support their health. By improving overall numbers, functional capacity and Mitochondrial DNA Repair Rate, we are beginning to unlock the answers to true preventative medicine and the ability to address symptoms and overall disease impact on quality of life. This will finally lead to tangible and curative remedies to all the diseases that ail us.
