Are people overreacting to high cholesterol? Or is it just a number that you shouldn’t stress about? If you’ve seen conflicting advice online, you’re not alone. Cholesterol is a hot topic that just won’t go away—and for good reason! If you think all you need is a diet overhaul, or that it no longer matters, you might want to stick around, because you could be missing key insights about your health. (Based on the insights of Dr. Paul Zalzal and Dr. Brad Weening)
Key Takeaways
- High cholesterol is still a real health problem, not just a number.
- Most cholesterol is made by your own body, not just from what you eat.
- The type of cholesterol—and how much of it gets into your arteries—matters most.
- For some people, lifestyle changes aren’t enough: medication has a major role.
- New cholesterol tests and drugs are changing the game.
- Making informed decisions with your doctor is essential.
Let’s break it down into easily digestible points!
1. Cholesterol Is Essential—But Too Much Can Hurt You
Cholesterol isn’t the villain you’ve been led to believe. Your body needs it. It helps build the membranes around your cells, makes hormones (like estrogen and testosterone), and even helps you digest food. Without enough cholesterol, your body literally can’t function.
But—here’s the catch—too much of the wrong kind can build up in your blood vessels, blocking them and leading to heart attacks, strokes, and poor circulation (think: leg pain or even trouble walking). So, cholesterol isn’t evil, but it can get you in trouble if it goes unchecked.
2. Most Cholesterol Is Manufactured By Your Body
Did you know about 85% of your cholesterol is made by your liver, thanks to your genetics? Only about 15% comes straight from your diet. That means some of us are just programmed to make more cholesterol than others—no matter how many salads we eat!
That’s why, for many, eating better and moving more are helpful, but they can only make a dent. If you have high cholesterol, it’s not your fault, and blaming your diet is outdated thinking.
3. Not All Cholesterol Is Created Equal
You’ve probably heard the terms LDL (low-density lipoprotein), HDL (high-density lipoprotein), and triglycerides. Here’s a quick rundown:
- LDL: Known as the “bad” cholesterol; more likely to deposit in your arteries.
- HDL: The “good” kind; helps clear cholesterol out of your arteries.
- Triglycerides: Another type of blood fat that, if high, raises your risk too.
But it gets even more sciencey: there’s also Lp(a) (lipoprotein little a) and apoB (apolipoprotein B), new markers that may tell you even more about your risk for heart disease. Watch for those terms in your next checkup!
4. High Cholesterol is Often Silent—Until Problems Strike
Here’s the tricky part: you usually feel nothing when your cholesterol is high. It’s a silent problem. Many people don’t discover an issue until a routine blood test—or their first heart attack or stroke. That’s why routine screening matters, even if you feel perfectly healthy.
5. When Should You Get Checked?
The rules differ by country, but in general:
- In the US: Start at age 19, and repeat every five years.
- In Canada: Usually age 30, unless you have risk factors like diabetes, smoking, or a strong family history of early heart attacks or strokes.
If you have super high cholesterol or a family history of heart problems, get checked sooner! In some tight-knit communities, certain genetic mutations are more common, leading to sky-high cholesterol levels in multiple family members.
6. How Are Cholesterol Levels Measured—and What’s “Normal”?
Cholesterol comes as a “panel”—total cholesterol, LDL, HDL, and triglycerides. International units may differ (millimoles per liter internationally, milligrams per deciliter in the U.S.), but the important number for most is LDL.
If you’ve had a heart attack or stroke, the minimum goal for your LDL is below 1.8 mmol/L (and possibly even tighter—below 1.4 mmol/L—according to newer guidelines in Europe). If you’ve never had an event, doctors estimate your overall risk based on factors like age, blood pressure, and smoking status to decide if you need medication.
7. Primary vs. Secondary Prevention: What’s the Difference?
- Primary prevention means preventing a first heart attack or stroke.
- Secondary prevention is about stopping a second event if you’ve already had one.
Why does it matter? People in secondary prevention need their cholesterol lowered even more aggressively.
8. Statins and Other Medications: What You Need to Know
You’ve probably heard of statins—they’re the most prescribed cholesterol-lowering drugs. They’re not without side effects (10–15% of people get muscle aches, for example), and there’s a very slight increase in risk for diabetes (but mainly in those already predisposed). The benefits—like preventing heart attacks and strokes— usually far outweigh the risks.
Other medications include:
- Ezetimibe: Lowers cholesterol a further 20% by preventing its absorption in the gut.
- Bempedoic Acid: A newer, muscle-friendly drug that lowers cholesterol by about 20%, but only works in the liver (so, less muscle pain risk).
- PCSK9 Inhibitors: Injectable and powerful—can lower LDL by 50%. Pricey, but highly effective, usually reserved for severe cases.
New drugs are even being developed to target specific markers like Lp(a).
9. Natural Approaches—Do They Actually Work?
Lots of people look for natural solutions like red yeast rice, niacin, or plant sterols:
- Red yeast rice: Contains a natural statin. Works, but you’re still getting a statin, and supplements are poorly regulated.
- Niacin: Once popular, but recent studies show it doesn’t add benefit and can have significant side effects.
- Plant sterols: Can lower cholesterol by about 10%, but often aren’t enough on their own.
Bottom line: Natural remedies might help a little, especially in people at low risk, but if your numbers are high, medication may be necessary.
10. Diet and Lifestyle Still Matter (But Aren’t the Whole Story)
While you can’t change your genes, you can help control your cholesterol by:
- Eating lots of fiber (whole grains, fruits, and veggies)
- Choosing healthy fats (olive oil, nuts, avocado)
- Limiting processed and fried foods
- Exercising 150 minutes a week
- Not smoking
But if you need medication, don’t feel bad—it’s about doing what works for your health, not dogma.
11. It’s Your Health—Be the Driver, Not Just the Passenger
Ultimately, you need to be in charge of your health. Talk with your doctor, understand your numbers, ask questions, and make decisions together. Whether it’s medication, lifestyle, or a bit of both, your values and goals matter.
Conclusion
Despite what you might see on social media, high cholesterol isn’t just a number. It’s a real risk factor for serious problems—but it’s also manageable with the right combination of lifestyle and (if needed) medications. Screening, understanding your risks, and having honest conversations with your healthcare provider will set you up for the best outcome.
