He went to his doctor for a routine checkup. Otherwise healthy, active, ate reasonably well. The only thing that flagged on his labs was cholesterol at 280, LDL moderately elevated. He had some chest pain one night, went to the hospital. They ran an echocardiogram, a cardiac calcium score, and a Holter monitor. Everything came back clean. Zero plaque. No arrhythmia. No structural problems.
His doctor still recommended a statin.
When he brought this to a functional medicine provider, the conversation went differently. If all your cardiac function tests show zero plaquing, you’re not pre-diabetic, your hormones are good, and you exercise and eat well, what exactly would lowering the cholesterol accomplish?
That question had no good answer. Because in this case, lowering the cholesterol wouldn’t have accomplished anything. It would have addressed a number on a lab report while the actual risk factors (none, in this patient’s case) remained unexamined.
What Cholesterol Is and Why the Body Makes It
Cholesterol is not a disease. It’s a molecule the body produces for specific, essential purposes.
It is required for cell membrane integrity, particularly in the brain. Without adequate cholesterol, neurons don’t function properly.
It is the building block for sex hormones. Testosterone, estrogen, progesterone, cortisol. Every one of these is synthesized from cholesterol. Drive cholesterol too low and hormone production drops with it.
Vitamin D synthesis requires cholesterol. So does immune function.
Patients at Med Matrix who are on high-dose statins sometimes come in with cholesterol levels around 110. Optimal is below 200. A level of 110 is not optimal. It’s a deficit of something the body needs to run. When that person complains of low libido, fatigue, brain fog, and mood problems, the statin’s suppression of cholesterol and CoQ10 is worth looking at as a cause.
The question is not how low can we get this number. The question is why is the body making more cholesterol than usual, and is that causing a problem?
Why LDL Is a Poor Predictor on Its Own
The conventional model treats LDL as the key cholesterol marker. Total cholesterol above 200 or LDL above a certain threshold means a statin.
Recent large-scale research, studies involving hundreds of thousands of people, has challenged this model significantly. Lower cholesterol correlates with higher rates of cardiovascular disease, stroke, dementia, and death in these studies. Not lower risk. Higher risk.
This is not fringe research. It is increasingly well-supported data that challenges decades of clinical practice.
LDL by itself is a poor predictor of cardiovascular disease. What matters more is whether the LDL is causing a problem, which depends on other factors.
A person with high LDL but optimal metabolic health, no insulin resistance, low inflammation, no plaque formation on imaging, is not necessarily at high cardiovascular risk. The high LDL number, by itself, doesn’t tell you much.
What does tell you more: VLDL (very low-density lipoprotein), which is more associated with plaque formation. Apolipoprotein B, which is responsible for plaque formation. Lipoprotein(a), which is more closely linked to cardiovascular disease than total cholesterol or LDL. Particle size and whether LDL is oxidized.
None of these are on a standard lipid panel.
The Insulin Resistance Connection Everyone Misses
Insulin resistance is the most significant driver of elevated cholesterol that conventional medicine doesn’t adequately address.
When you eat too much sugar over time, insulin, the hormone that regulates blood sugar, becomes less effective at doing its job. Blood sugar control degrades. And as insulin resistance increases, VLDL production rises, LDL particles become smaller, and those smaller particles are the ones that form plaque when combined with inflammation and endothelium damage.
The endothelium is a single cell layer that lines the inside of blood vessels. When it gets inflamed, from ultra-processed food, seed oils, environmental toxins, it impairs nitric oxide production. Nitric oxide expands blood vessels and delivers blood to tissues. Without it, blood vessel health deteriorates and plaque starts forming.
So the actual root of many cardiovascular cases is: too much sugar, driving insulin resistance, which increases VLDL and creates the conditions for LDL to become problematic, alongside endothelial inflammation from poor diet and toxin exposure.
Giving someone a statin lowers the cholesterol number. It doesn’t fix insulin resistance. It doesn’t reduce endothelial inflammation. It doesn’t address the root cause. And statins may actually worsen insulin resistance, the same thing they’re supposed to be prescribed to protect against.
What Statins Actually Do to the Body
Statins work by reducing cholesterol synthesis in the liver. That’s the mechanism. The downstream effects are significant.
One of the biggest: statins block the production of CoQ10 (coenzyme Q10), a molecule critical for cellular energy production, muscle function, and cardiac performance. When CoQ10 is suppressed, the result is fatigue, exercise intolerance, muscle weakness, and brain fog.
Patients on high-dose statins who come in complaining they can’t exercise the way they used to, that they’re exhausted, that their brain doesn’t feel sharp, often get told that’s just aging. It may not be. It may be a direct effect of an 80-milligram statin blocking CoQ10.
Since cholesterol is required to produce estrogen, progesterone, testosterone, and cortisol, reducing cholesterol suppresses sex hormone production. Low libido. Low motivation. Poor stress tolerance. Mood changes. These are real side effects in real patients.
Statins may also worsen insulin resistance. The same condition that is a primary driver of cardiovascular risk gets worsened by the medication prescribed to reduce that risk.
Why Doctors Keep Prescribing Them Anyway
This is not about whether doctors are good or bad. Most are trying to help their patients. The problem is structural.
Insurance guidelines require statin prescriptions at certain cholesterol thresholds. Providers who don’t comply face reduced pay per patient. Doctors who work within insurance-driven practices can have their income reduced if patients above a cholesterol threshold are not put on statins, regardless of individual clinical context.
If a patient is not medicated and has a cardiovascular event, the liability exposure is significant. The guidelines say medicate. The doctor didn’t. The legal and financial consequence falls on the provider.
This creates a system where prescribing a statin to anyone above a threshold is the path of least resistance, least liability, and least financial penalty. It’s not about what’s best for that individual patient. It’s about compliance with guidelines built around aggregate population data, not individual risk assessment.
Pharmaceutical companies have generated an estimated two to three hundred billion dollars from statin sales. That financial structure does not incentivize reassessing whether the guidelines are correct.
What Actual Cardiovascular Risk Assessment Looks Like
A cardiac calcium score CT scan shows whether plaque is actually forming. A calcium score of zero means no plaque, regardless of LDL level. If a patient has no plaque, no insulin resistance, balanced hormones, and no inflammatory markers elevated, the case for a statin is weak regardless of what the total cholesterol number says.
An expanded cardiac risk panel looks beyond standard lipid panels: apolipoprotein B, lipoprotein(a), VLDL, inflammatory markers, fasting insulin, hemoglobin A1C. This is the information that actually predicts cardiovascular risk.
If insulin resistance is present, addressing it through dietary change, lifestyle intervention, and hormonal optimization addresses the root cause rather than masking the number.
Patients who reverse insulin resistance, lose significant weight, and normalize their A1C sometimes find their cholesterol normalizes on its own, without a statin. The underlying metabolic dysfunction was driving the elevated cholesterol, and treating the dysfunction treated the number.
The Conversation Worth Having
If you’re on a statin and experiencing fatigue, brain fog, low libido, or reduced exercise capacity, those symptoms warrant investigation before being attributed to aging.
If your doctor wants to put you on a statin because your LDL is above a threshold, asking for a cardiac calcium score and a more complete risk assessment is reasonable. A calcium score of zero changes the clinical picture significantly.
If you’ve been told cholesterol is the primary driver of your cardiovascular risk, the current research suggests that insulin resistance and inflammation are stronger drivers. Addressing those through root-cause work may be more effective than lowering a number.
The standard of care on cholesterol is being revised as large-scale evidence accumulates. Medical textbooks and clinical guidelines take time to catch up. In the meantime, patients are getting a simplified model that may not match their actual risk.
You’re allowed to ask more questions.
