What it means
LDL is the cholesterol inside the particles that can build plaque in your artery walls. Most reports work it out from your other three numbers, and the 2026 guideline prefers two newer equations to the 1972 formula many labs still print. A meal moves it about 8 points at most.
What moves it most

When to get help now
Chest pain or pressure isn't a cholesterol question: call 911. Triglycerides of 500 or more need a doctor within days, 1000 or more the same week, and severe stomach pain with them is the ER. Cholesterol rises in pregnancy on purpose, so take any number to your midwife or doctor. If you take a cholesterol medicine, your goal comes from your prescriber.
