Decoding Disease with Dr. Rue
Learn to see your body through a different lens.
There comes a point where you begin to sense that what you are experiencing cannot be fully explained by symptoms alone. Patterns repeat, progress feels incomplete, and something deeper is asking to be understood. I’m Dr. Rue, a naturopathic physician focused on chronic illness and integrative oncology, where the work is not about chasing conditions, but about observing the terrain in which they arise.
In this space, we explore how the body adapts, how systems communicate, and how environment, metabolism, and lived experience shape what you feel day to day. The body is not random, and it is not working against you. It responds in ways that reflect its internal and external worlds. As you begin to understand those responses, your relationship with your health begins to change.
These are quiet, intentional conversations designed to bring clarity without removing complexity. If you have ever felt that your experience does not fit into a simple explanation, you are not alone. This is a place to listen more closely, to reconnect, and to begin seeing what may have been there all along.

Fission and Fusion: The Mitochondrial Network | Ep. 049

What if some of the most important decisions happening inside your body are being made by structures too small to see?
This episode explores the remarkable balance between mitochondrial fusion and fission, two processes that constantly shape the health of the cellular environment. Far from being simple energy producers, mitochondria exist within a dynamic network that continuously adapts, communicates, connects, and separates in response to changing conditions.
These cellular behaviors influence far more than energy alone. They reflect a deeper biological story about resilience, adaptation, renewal, and survival. Understanding this hidden world offers a new perspective on why health is never static and why the body's ability to maintain balance may be one of the most important factors in long-term wellness.

In the last episode, we talked about mitochondrial biogenesis, the process your cells use to build new mitochondria. But creating new mitochondria is only part of the story. Because mitochondria don't function as isolated batteries floating around inside your cells. In fact, if we could shrink ourselves down and watch them under a microscope, we wouldn't see thousands of tiny static power plants. We would see a constantly shifting network, mitochondria joining together, separating apart, changing shape, reorganizing themselves in real time. Scientists call these processes fusion and fission. Fusion is when mitochondria join together. Fission is when mitochondria split apart. Now at first glance, that may sound like an enormous amount of work. Why not simply live them alone? Because the goal isn't simply to make energy. The goal is to make energy reliably. Let's start with fusion. Imagine two businesses that are struggling for different reasons. One has resources but poor infrastructure. The other has strong infrastructure but limited resources. Separately, both struggle. Together, they become stronger. Fusion works in a similar way. When mitochondria join together, they can share resources and support one another during times of stress. It's one of the ways the cell helps maintain stable energy production when conditions become challenging. But support is only half the equation. The other half is quality control. Imagine a factory producing defective products. Before you can solve the problem, you first have to identify where the problem exists. That's where fission comes in. Fission allows sections of the mitochondrial network to separate and be evaluated. In many ways, is the sales wave isolating potential problems before they affect the entire network. And once those damaged sections are identified, other systems can take over. This is where the story begins connecting. Biogenesis builds new mitochondria. Fusion helps support the network. Fission helps identify problems. Mitofigy removes damaged mitochondria. This isn't a collection of unrelated processes. It's an integrated maintenance system designed to keep energy production running reliably, and that's why this matters. Because your energy isn't determined solely by how many mitochondria you have, it's also influenced by how effectively those mitochondria work together. Sometimes the problem isn't simply damaged mitochondria. Sometimes the network itself isn't functioning the way it should. Communication becomes less efficient, quality control becomes less effective, and energy production begins to suffer. This may help explain why mitochondria dysfunction shows up in so many different conditions. For example, it shows up as we age, in metabolic disease, in neurodegenerative conditions, and even in cancer. One of the themes you'll hear throughout this series is that health depends on quality control, identifying problems, repairing what can be repaired, removing what can't. Cancer becomes possible when enough of those quality control systems begin breaking down, and mitochondria are deeply involved in that story. The encouraging part is that biology is rarely as fixed as people think. The mitochondrial network is dynamic, responsive, constantly changing in response to the environment around it. Which means understanding these systems isn't just interesting biology. It may help us better understand health, disease, resilience, and aging itself. The big takeaway is this. Minochondria are not static power plants. They are part of a living network. A network that is constantly monitoring itself, supporting itself, and maintaining itself. Because the goal isn't simply to make energy. The goal is to make energy reliably. But even the best maintenance systems have limits. There are times when the damage becomes too great. Times when repair is no longer enough. And when that happens, the cell faces one of the most important decisions in biology. Not whether to repair, not whether to adapt, but whether it should continue living at all. That's exactly what we'll begin exploring next time when we discuss apoptosis, sometimes called programmed cell death.
