If your doctor tells you to lower your blood pressure to 120 over 80, he or she is not wrong in saying so. But after age 60, chasing that exact number can in some cases do more harm than good. The number itself is not flawed, but the problem is how broadly it applies, and is often applied to people on whom it has never actually been tested.
This is not an argument against treatment or medication. It’s about understanding where this widely cited goal comes from, what changes in the body after age 60 make a flat number risky for some people, and what a more personalized goal could look like depending on your age and health profile. (Based on opinions of Dr. Jason Collins)
Key takeaways
- The 120/80 goal came from studies in younger, healthier adults — not the typical person with multiple conditions after age 60.
- Severe low blood pressure in older adults is associated with more falls, dizziness, and kidney strain in real-world use.
- Cardiologists increasingly recommend a personal goal based on age, health conditions and symptoms rather than one number for everyone.
- Symptoms such as dizziness when standing up, brain fog, and unusual fatigue can indicate that your current target blood pressure level is too low for your body.
Where did the 120/80 goal actually come from?
For decades, researchers have observed that adults with blood pressure between 120 and 80 tend to have fewer heart attacks and strokes, and this observation has become the standard goal. But most of the early studies behind that number were done in younger adults with healthy kidneys and healthy brains who take little or no other medications, not someone in their late 60s or 70s who has two or three conditions and takes several prescriptions a day. The number is not wrong. It is simply being generalized to a population around which it was not originally built.
What happens to your arteries and brain after the age of sixty?
Arteries harden with age, think of the difference between a new flexible rubber hose and one that has spent a decade in the sun. Stiffer arteries mean that the heart has to work harder to move blood, and that the brain, kidneys and heart gradually rely on a slightly higher basal pressure to function normally. When blood pressure is pushed aggressively toward 120, some older adults are unable to compensate, leading to dizziness, brain fog, fatigue, and unsteadiness.
This is important because falls in older people are rarely minor. A 2019 review published in the Journal of the American Geriatrics Society found that severely lowering blood pressure in older adults significantly increases the risk of falls and fall-related injuries — a risk that is easy to overlook when the only thing being measured is the number on the cuff.
The subtleties in major blood pressure trials
The 2015 SPRINT trial, which studied more than 9,000 adults with an average age of 68, found that a goal of less than 120 systolic blood pressures reduced heart attacks and cardiovascular deaths compared with a goal of less than 140. This finding has pushed many doctors toward more aggressive goals in older patients. But the trial excluded anyone with diabetes, previous stroke, dementia, advanced kidney disease, or severe frailty — meaning participants were among the healthiest and most resilient older people, and not necessarily representative of the average person over 60.
Even within that healthier group, the lower target came with more dizziness, more fainting, more kidney problems, and more drops in blood pressure when standing. A 2021 follow-up trial in China, the STEP trial, which included more than 8,500 adults ages 60 to 80, found a similar pattern: a real cardiovascular benefit from lower targets, along with real side effects in normal patients.
Find your personal blood pressure goal
Many cardiologists now use a framework based on three general profiles for older adults:
One profile – Ages 60 to 79 years, physically active, mostly independent, does not have serious illnesses such as kidney disease or dementia, and does not experience dizziness when standing. A target of less than 130 over 80 is generally considered appropriate, with significant cardiovascular benefit and relatively low risk of side effects.
Second profile — They are between 60 and 79 years old, but have multiple conditions such as diabetes or kidney problems, or take three or more medications, and sometimes feel dizzy. A goal of 130 to 140 systolic pressures is often considered safer; The 2021 American College of Cardiology guidelines suggest that more aggressive targets in this group could cause more harm than good.
Profile three – Age 80 or older. Research generally supports a goal of systolic pressure between 130 and 150, depending on daily symptoms. Adults who sit comfortably at 120 degrees without dizziness or fatigue may tolerate additional protection, but those who feel unsteady or foggy are often better served by the higher range.
Signs Your Current Target May Be Too Aggressive
Several daily symptoms can indicate that the target blood pressure has been set at a lower level than the body can comfortably tolerate: dizziness upon standing (especially in the morning), persistent brain fog, unusual fatigue despite adequate sleep, feeling unsteady while walking, readings that regularly drop below 100 systolic pressure, muscle cramps or electrolyte imbalance, which can occur with some diuretic medications. None of these can be dismissed as “just getting older” – they are worth discussing with your doctor.
What to do before your next doctor’s appointment
Three practical steps that can make a real difference in that conversation. First, determine which of the three profiles best fits your current life — not how active you were a decade ago. Second, track how you feel along with your blood pressure readings for a week. A record that shows real-world symptoms is often more useful to the doctor than a single reading done in an exam room. Third, ask a specific question: “Given my age, my condition, and the symptoms I’ve been tracking, what is my personal blood pressure goal?” This question shifts the conversation from a general guideline to an individual-based goal.

Frequently asked questions
Does this mean I should stop trying to lower my blood pressure?
No, blood pressure medications and management still significantly reduce the risk of cardiovascular disease. The goal is not to avoid treatment, but to make sure that the specific goal you are aiming for is appropriate for your age, health condition, and how you feel day to day.
Should I adjust my medications based on this information?
No — Never change or stop your blood pressure medication without consulting your doctor first. This article is intended to help you have a more informed conversation with your doctor, not to replace his or her guidance.
What if my doctor doesn’t agree with these profiles?
Your doctor knows your complete medical history and may have specific reasons for your current condition. These profiles are a general framework increasingly used in cardiology, and are not a substitute for individual medical judgment – have the conversation, but trust your doctor’s assessment of your specific case.
How long should I monitor my symptoms before seeing my doctor?
About a week is usually enough to show a meaningful pattern between your readings and how you feel, but if you experience worrisome symptoms like fainting or severe dizziness, don’t wait — call your doctor right away.
Quick start checklist
- ☐ Determine which of the three age/health characteristics best fits your life today
- ☐ Track your blood pressure readings daily for 7 days
- ☐ Record how you feel (dizzy, foggy, tired, rested) next to each reading
- ☐ Note any systolic pressure readings below 100
- ☐ Watch for muscle cramps or signs of electrolyte imbalance
- ☐ Write your specific question for your doctor in advance
- ☐ Ask: “What is your personal blood pressure goal?” On your next visit

Blood pressure goals should always be set individually with a licensed physician, taking into account your complete medical history, current medications, and symptoms. Never adjust or stop blood pressure medication without consulting your doctor first. If you experience chest pain, sudden severe dizziness, fainting, or signs of a stroke, seek emergency medical attention immediately.
