A blood pressure of 103/69 mmHg is a good reading. It falls squarely within the normal range, which is defined as below 120/80 mmHg. Not only is it normal, but it sits in a zone associated with lower long-term cardiovascular risk, well above the threshold where doctors start worrying about blood pressure being too low.
Where 103/69 Falls on the Scale
Blood pressure categories, based on guidelines from the American College of Cardiology and the American Heart Association, break down like this:
- Normal: below 120/80 mmHg
- Elevated: 120 to 129 systolic (top number) with diastolic (bottom number) still below 80
- Stage 1 hypertension: 130 to 139 systolic, or 80 to 89 diastolic
- Stage 2 hypertension: 140 or higher systolic, or 90 or higher diastolic
At 103/69, both numbers are comfortably in the normal category. The updated 2025 guidelines reaffirm a treatment goal of below 130/80 for most adults and actually encourage achieving below 120/80 when possible. Your reading already meets that more ambitious target.
Is It Too Low?
No. Blood pressure is generally considered too low (hypotension) when it drops below 90/60 mmHg. Some clinicians also flag a diastolic reading under 60 on its own. Your systolic of 103 is 13 points above the low threshold, and your diastolic of 69 is 9 points above it. There’s a comfortable margin on both numbers.
What matters more than any single cutoff is how you feel. Blood pressure in the low-normal range only becomes a concern if it causes symptoms like dizziness when standing, lightheadedness, blurred vision, unusual fatigue, nausea, or difficulty concentrating. If you feel fine at 103/69, it’s simply a healthy reading.
Why Some People Run Lower
Plenty of people have resting blood pressure in the low 100s as their baseline. Regular physical activity is one of the most common reasons. Athletes and people who exercise consistently tend to develop stronger hearts that pump more blood per beat, meaning the heart doesn’t need to generate as much pressure to circulate blood effectively. Studies of young endurance athletes show they commonly have lower diastolic blood pressure than non-athletes as a normal physiological adaptation.
Body size, age, genetics, and hydration all play a role too. Younger adults and women before menopause are more likely to have naturally lower readings. If your blood pressure has consistently been in this range, that’s your normal.
During Pregnancy
If you’re pregnant and wondering about this number, 103/69 is typical. Blood pressure naturally dips during the second trimester due to hormonal changes that relax blood vessel walls. In a large study of singleton pregnancies, the average blood pressure at 20 to 24 weeks was about 110/63, and similar at 28 to 32 weeks. A reading of 103/69 is right in that expected range. Concern during pregnancy starts when blood pressure climbs to 130/80 or higher, not when it dips into the low 100s.
The Long-Term Picture
Lower blood pressure within the normal range is consistently linked to better cardiovascular outcomes. Research on cardiovascular mortality shows that systolic blood pressure below about 131 mmHg is associated with significantly lower risk of death from heart disease. Your systolic reading of 103 is well within that protective zone. The relationship between blood pressure and heart health is dose-dependent: the lower you go within a healthy range, the less strain on your arteries, heart, and kidneys over decades.
Getting an Accurate Reading
If 103/69 came from a single measurement, it’s worth knowing that technique can shift your numbers quite a bit. Common factors that affect accuracy include:
- Talking during the reading: can raise both numbers by about 10 points
- Full bladder: can add roughly 15 points to systolic and 10 to diastolic
- Cuff placed over clothing: can inflate the reading by 5 to 50 points
- Wrong cuff size: a too-small cuff adds about 10 points to systolic
- Back unsupported: can raise the reading by 6 to 10 points
- Arm hanging unsupported: can add 6 to 10 systolic points
For the most reliable number, sit quietly for five minutes beforehand, keep your back supported, rest your arm on a flat surface at heart level, and use a properly sized cuff on bare skin. Taking two or three readings a minute apart and averaging them gives you a better picture than any single check. If your reading was taken under good conditions, 103/69 is a number you can feel good about.
