  5. HDL by age

Your goal doesn’t change with age. LDL under 100 mg/dL, 70 or 55 depending on your risk, at 25 or at 65. What changes with age is how common a high number is: 6% of Americans in their 20s and 30s have a total of 240 or more, 16.7% in their 40s and 50s, and after 60 women overtake men almost three to one.

What we’d do

Hold your LDL and non-HDL against the goal for your risk, never against people your age. Get a first panel by 19 if you haven’t, test at least every 5 years after that, and test again around menopause. If your number is high young, start on it young, because the years add up.

Why people look for an age chart

Most charts online list a “normal” range for each decade, and a lot of people search for one to see if they’re doing all right. But a chart of what’s common only shows what most people have. A high number that’s common at your age still raises your risk, the same as it would for anyone.

The 2026 US guideline gives no age table. It sets the same LDL and non-HDL goals for every adult, and your risk, which does rise with age, decides which goal is yours.

Who has a high total cholesterol

Who has a high total cholesterolShare of US adults with 240 mg/dL or more, 2021 to 2023

NHANES, August 2021 to August 2023 (CDC NCHS Data Brief 515). All adults: 11.3%.

The numbers come from NHANES, the CDC survey that draws blood from a sample of Americans, for August 2021 to August 2023. Overall, 11.3% of adults 20 and over had a total of 240 or more. That’s down from about 18% around 2000, and it has barely moved since 2014.

Men’s numbers peak in their 40s and 50s, at 18.3%, and drop to 5.6% after 60. Women’s climb the whole way, from 4.7% in their 20s and 30s to 16.4% after 60. The data brief doesn’t say why the men’s number falls.

Why it rises in your 20s, 30s and 40s

LDL and non-HDL climb an average of 1 to 2 mg/dL a year in young adulthood, the guideline says. Nobody feels it, since high cholesterol has no symptoms, so the guideline asks for a first test at 19 and another at least every 5 years. Children get one test between 9 and 11.

Women get an extra step at menopause. In the SWAN study of 1,054 women, total cholesterol, LDL and ApoB jumped in the year either side of the last period, while other risk factors rose slowly with age. Why does cholesterol go up after menopause?

Why age doesn’t earn you a higher goal

A high LDL at 30 has more years to add up than the same number at 60. In a 2012 analysis of 312,321 people, LDL held 39 points lower from early life went with about 55% less coronary heart disease, three times what the same drop gave when a statin started in middle age. Am I too young to worry about cholesterol?

HDL by age

Low HDL (under 40) is more common in men at every age, 21.5% against 6.6% of women, and it gets less common as people get older. HDL has no goal in the 2026 guideline, and how to raise HDL explains why pushing it up hasn’t helped.

Is my cholesterol bad? puts your own panel against your goal, whatever your age.

Your numbers

Showing an example panel. Type your own numbers.

Leave LDL blank if your report says calculated.

ApoB, if your report has it
Did you fast before the test?
Which fits you?
Both

Both sets of changes apply. Start with triglycerides, since they move in weeks.

Your 215 is 38 HDL and 177 everything else.

LDL

The NIH equation, from your other three numbers

134mg/dL, 3.5 mmol/L

The newer equation says 134, and many labs would print 129. A gap of 5 mg/dL.

Clears 0 of 3 goal lines. Compared with under 100, the goal at borderline or intermediate risk. Ask your doctor for your PREVENT score to find your rung.

Non-HDL

Total minus HDL: the cholesterol in every particle that can clog an artery

177mg/dL, 4.6 mmol/L

Compared with under 130 mg/dL. Its goals sit 30 points above LDL's, and with triglycerides of 150 or more the guideline finds it the better guide.

Triglycerides

Not fasting

240mg/dL, 2.7 mmol/L

Over the nonfasting line of 175, the guideline's line for treating triglycerides with lifestyle.

HDL
38Low, under 40. Higher isn't a goal.
Total to HDL
5.7No goal in the 2026 guideline
Triglycerides to HDL
6.3No goal either
Remnant, an estimate
43Total minus HDL minus LDL. Rises with triglycerides
Total
215Under the NCHS line of 240, and the guideline sets no goal for it
34

You're 34 points from under 100, the goal at borderline or intermediate risk. The biggest single food change in trials takes off about 13. A gap this size is a conversation to have with your doctor.

Next step. Start with alcohol and sweet drinks for your triglycerides, add the fat swap and 10 g of psyllium for your LDL, then retest at the same lab in 6 to 12 weeks. The LDL plan
