The Problem Isn’t Cholesterol — It’s Chronic Blood Vessel Inflammation
Cholesterol is an incredible molecule. It’s a structural building block and a biochemical precursor that your body relies on every single day. When cholesterol becomes associated with disease, the issue is most often how it’s transported (lipoproteins), how it’s modified or oxidized, and the presence of chronic inflammation—not cholesterol itself.
Some of cholesterol’s essential roles in the body include:
- Steroid hormone production — precursor to cortisol, aldosterone, estrogen, progesterone, and testosterone
- Cell membrane structure — critical for membrane fluidity and cellular signaling (“lipid rafts”)
- Nerve insulation — a major component of myelin
- Vitamin D production — precursor to cholecalciferol (vitamin D₃) in the skin
- Bile acid formation — required for digestion and absorption of fats and fat-soluble vitamins (A, D, E, K)
- Immune signaling — lipid rafts organize immune receptors (including T- and B-cell activation)
- Tissue repair and growth — concentrated in areas of cell turnover and wound healing
- Lung surfactant stability — supports proper expansion of the alveoli
- Brain development and function — essential for synapse formation and neuronal health
- Skin barrier integrity — part of the epidermal lipid matrix that prevents water loss
One of my school mentors used an analogy that stuck with me: cholesterol is like the firemen the liver sends out.
If the fires are controlled, fewer firemen are needed. But if we only focus on lowering cholesterol—through medications or even natural approaches—without addressing the underlying damage, it’s like firing the firemen while the fire continues to burn.
That “fire” is damage and ongoing inflammation of the blood vessel lining, known as the endothelium.
When the endothelium is injured, your immune system responds with inflammation. This is a remarkable and necessary process. Short-term, well-regulated inflammation is how we heal—from cuts and injuries, infections, and tissue repair. It activates stem cells, clears debris, and restores function.
Problems arise when inflammation becomes chronic, persistent, or dysregulated. Much of what we call “anti-inflammatory” medicine—diet, supplements, light therapies, movement, and stress regulation—is really about controlling chronic inflammation, not suppressing the body’s natural healing response.
This is where cholesterol comes in. When blood vessels are damaged, the body initiates complex repair processes involving immune cells, connective tissue, and lipids—including cholesterol. These processes help stabilize injured areas and prevent dangerous events like clot rupture, which could otherwise lead to heart attacks or strokes.
Over time, cholesterol became the primary target in cardiovascular care. Medications like statins unfortunately do not replace addressing why the vessel wall was injured in the first place.
Historically, cholesterol-lowering drugs became a dominant focus of cardiovascular treatment. For example, Lipitor became one of the highest-grossing medications in history reaching $12.6 billion in annual sales in 2006. While medications can be helpful when appropriately used, this narrow focus often pulled attention away from the root causes of vascular injury and inflammation and caused worse outcomes for many patients.
For those interested in the history of cholesterol and statin therapy, the documentary *Statin Nation* by Justin Smith for free on YouTube offers a great overview.
So what actually damages blood vessels? The primary drivers of endothelial injury include:
- Diets high in processed foods and refined sugars
- Physical inactivity
- Smoking
- Excess alcohol
- Chronic infections
Genetics, toxin exposures, chronic stress, and poor sleep can further amplify these risks and make some individuals more vulnerable.
The encouraging part: this is completely changeable!
Here’s the good news—these outcomes are not fixed. Addressing the foundations of health can dramatically improve:
- Energy and resilience
- Healing and recovery
- Immune function
- Cardiovascular health
- Overall quality of life
Natural and integrative medicine allows us to be more targeted with supplements, therapies, and treatments to optimize and accelerate this healing process. I truly enjoy walking alongside patients in this work.
That said, you can do a lot without supplements or treatments alone. The foundations matter most. As the saying goes:
“You can’t supplement a sh*ty diet.”
If you want support or you’re curious about optimizing your health further—addressing deeper contributors like chronic infections, mold exposure, toxins, or metabolic dysfunction—an office visit can help us build a personalized and effective plan.
My goal is to help you heal well, live fully, and build long-term health—not just chase numbers on a lab report. Let's make life be to the full together. (503) 482-6888
