4. Ignoring High Cholesterol
Has a doctor ever told you your cholesterol is “a little high” but not to worry? That advice can be misleading. The real danger isn’t just cholesterol itself—it’s oxidized LDL, the form of LDL that’s been damaged by free radicals. Once oxidized, these particles turn into wrecking crews inside your arteries, sparking inflammation and forming plaques that gradually narrow blood flow. The biggest drivers? Genetics, chronic stress that keeps arteries inflamed, and processed foods disguised as “healthy.” If your doctor prescribes statins, don’t stop just because you feel fine. Lowering LDL reduces the amount available to oxidize. Like high blood pressure, oxidized LDL does its damage silently—until it shows up as heart attacks or strokes.
3. Not Managing Diabetes Properly
You might think, “I’m not diabetic, this doesn’t apply to me.” The problem is that high blood sugar can be damaging your blood vessels long before you’re ever diagnosed with diabetes. Imagine sugar as tiny crystals scratching the walls of your arteries from the inside, without pain or warning, for years. If your hemoglobin A1c (a 3-month average of your blood sugar) is above 6.5% or your fasting glucose is above 126 mg/dL on repeated tests, you’re in a dangerous zone. While new medications can help, managing diabetes is a lifelong commitment to a healthy lifestyle, and often, medication. Your pancreas has been with you your whole life; when it gets tired, it needs your help.
