The four categories
| Category | Systolic (mm Hg) | Diastolic (mm Hg) | Both or either |
|---|---|---|---|
| Normal | Below 120 | Below 80 | Both must apply |
| Elevated | 120 to 129 | Below 80 | Both must apply |
| Stage 1 hypertension | 130 to 139 | 80 to 89 | Either one is enough |
| Stage 2 hypertension | 140 or above | 90 or above | Either one is enough |
The conjunctions matter. Normal and elevated require both numbers to qualify; stage 1 and stage 2 need only one. A reading of 128 over 84 is stage 1 hypertension, because the diastolic value crosses the line on its own. Nearly half of all US adults have blood pressure at or above 130 over 80.
Separately, the guideline defines severe hypertension in non-pregnant people as a blood pressure above 180 over 120. Where there is no evidence of acute organ damage, it should be evaluated and treated in the outpatient setting by starting, restarting or intensifying oral medication promptly, rather than through an emergency department visit.
What changed in 2025: risk, not thresholds
The categories are the same as 2017. What is new is that the decision to medicate stage 1 hypertension now runs through a risk calculation rather than a blood pressure number alone.
The tool is PREVENT, developed by the American Heart Association in 2023, which estimates 10-year and 30-year cardiovascular risk in people aged 30 to 79. It takes age, sex, blood pressure, cholesterol and other health indicators, and it includes zip code as a proxy for social drivers of health. It is the first risk calculator to combine cardiovascular, kidney and metabolic measures in one estimate.
| Your situation | What the guideline recommends |
|---|---|
| Average blood pressure 140/90 or above | Start medication alongside lifestyle change |
| 130/80 or above with cardiovascular disease, previous stroke, diabetes or chronic kidney disease | Start medication alongside lifestyle change |
| 130/80 or above with PREVENT 10-year risk of 7.5 percent or more | Start medication alongside lifestyle change |
| 130/80 or above with PREVENT 10-year risk below 7.5 percent | Trial lifestyle change for 3 to 6 months, then start medication if the average is still 130/80 or above |
| Stage 2 hypertension | Start with two first-line agents of different classes in a single pill, preferred over two separate pills |
The single-pill combination recommendation for stage 2 is a practical change worth asking about by name. The guideline prefers a fixed-dose combination over two separate tablets specifically to improve adherence and shorten the time it takes to get control, and being handed two prescriptions where one combined pill exists is a reasonable thing to query.
The brain argument
The strongest new emphasis in the guideline is not about the heart. High blood pressure damages the small blood vessels of the brain, and the guideline states that more recent research confirms blood pressure affects brain health, including cognitive function and dementia. It recommends early treatment with a systolic goal below 130 mm Hg specifically to prevent cognitive impairment and dementia.
That reframes the case for treating a stage 1 reading in your forties or fifties, where the ten-year cardiac risk can look small enough to be dismissed. The relevant time horizon for the brain is longer than ten years, which is part of why PREVENT also produces a 30-year estimate.

The lifestyle numbers, with actual quantities
Lifestyle change is recommended for every category, including normal, and the guideline attaches numbers rather than adjectives.
- Sodium below 2,300 mg per day, moving toward an ideal limit of 1,500 mg. The guideline notes most US adults get their sodium from packaged and restaurant food rather than the salt shaker, so label reading beats putting the shaker away.
- Alcohol: ideally none. For those who choose to drink, no more than two drinks per day for men and no more than one for women.
- A heart-healthy eating pattern such as DASH, high in vegetables, fruit, whole grains, legumes, nuts and seeds, and low-fat or non-fat dairy, with lean meats, fish and non-tropical oils.
- Increased dietary potassium, a moderate physical activity program, weight management and stress management.
The guideline also expands the use of the plasma aldosterone-to-renin ratio as a screening test for primary aldosteronism, including in people with obstructive sleep apnea. Primary aldosteronism is a treatable cause of high blood pressure that is substantially under-diagnosed, and it is worth asking about if your pressure is hard to control, if you have low potassium, or if you have sleep apnea.
Pregnancy, which the guideline treats as its own subject
Blood pressure before, during and after pregnancy received a dedicated set of recommendations. Women with high blood pressure who are planning a pregnancy or are pregnant should be counselled about low-dose aspirin, 81 mg per day, to reduce the risk of preeclampsia. For pregnant women with chronic hypertension, meaning high blood pressure before pregnancy or diagnosed before 20 weeks, the guideline recommends treatment once systolic reaches 140 mm Hg or diastolic reaches 90 mm Hg, a tighter threshold reflecting evidence that closer control reduces serious complications. Postpartum monitoring matters too, and anyone with a history of pregnancy-associated high blood pressure is encouraged to have it measured at least annually.

Frequently asked questions
Is 130/80 high blood pressure?
Yes. Under the 2017 categories, retained in 2025, 130 over 80 is stage 1 hypertension. Whether it means medication depends on your other risk: with cardiovascular disease, stroke, diabetes, chronic kidney disease or a PREVENT 10-year risk of 7.5 percent or more, treatment starts alongside lifestyle change. Below that risk level, lifestyle change comes first for 3 to 6 months.
What is a normal blood pressure by age?
The guideline publishes no age-specific categories. The same four bands apply to all adults, and the overarching treatment goal is below 130 over 80 for all adults, with individual considerations for people requiring institutional care, those with a limited predicted lifespan, and pregnancy. Average blood pressure rises with age, but that is a description of populations, not a moving target.
Which number matters more, the top or the bottom?
Both are used, and either one crossing its threshold puts you in the category. The guideline expresses its brain-health recommendation in terms of a systolic goal below 130, and systolic pressure generally carries more predictive weight in older adults, but a raised diastolic on its own still defines hypertension.
Can I use my smartwatch to check my blood pressure?
The guideline advises against relying on cuffless devices, including smartwatches, until they demonstrate greater precision and reliability. Use a validated upper-arm cuff for any reading you intend to act on.
What is PREVENT and where do I get my score?
PREVENT is the American Heart Association's risk calculator, released in 2023, estimating 10-year and 30-year risk of heart attack, stroke and heart failure for people aged 30 to 79. It is the first to combine cardiovascular, kidney and metabolic measures, and it uses zip code as a proxy for social drivers of health. Your clinician can run it, and the 7.5 percent 10-year threshold is the one the guideline uses for treatment decisions in stage 1.
When to talk with a clinician
Get urgent care for a blood pressure above 180 over 120 accompanied by chest pain, breathlessness, weakness, difficulty speaking, vision change or severe headache, which suggests organ damage rather than severe hypertension alone. Book a routine review for any home average at or above 130 over 80, bringing a week of readings taken on a validated cuff. Two questions are worth asking directly: what is my PREVENT 10-year risk, and if I need two medicines, is a single-pill combination available.
