What each result on your readings means, in simple words — and everyday steps people often discuss with their doctor.
Education only, not medical advice. Consult with your provider about your own numbers.
Blood pressure
Normal blood pressure
What it means
Top number under 120 and bottom number under 80. Your heart and blood vessels are under a healthy amount of pressure.
Why it matters
Keeping blood pressure here lowers the long-term risk of heart attack, stroke and kidney disease.
Everyday steps to discuss with your doctor
Eat less salt (aim under 1,500–2,300 mg a day) and more fruits, vegetables and whole grains — the DASH eating plan.
Move most days — a brisk 30-minute walk counts.
Limit alcohol, don't smoke, and aim for 7–9 hours of sleep.
Elevated blood pressure
What it means
Top number 120–129 with the bottom number under 80. It's a little above normal — an early heads-up, not an emergency.
Why it matters
Without changes, elevated readings often rise into the hypertension ranges over time. Daily habits can usually bring them down.
Everyday steps to discuss with your doctor
Eat less salt (aim under 1,500–2,300 mg a day) and more fruits, vegetables and whole grains — the DASH eating plan.
Move most days — a brisk 30-minute walk counts.
Limit alcohol, don't smoke, and aim for 7–9 hours of sleep.
Take blood pressure medicines exactly as prescribed — don't stop on your own.
Recheck at home: sit quietly 5 minutes, feet flat, arm at heart level, two readings a minute apart.
Stage 1 hypertension range
What it means
Top number 130–139 or bottom number 80–89. This is the first step above normal. It is common and can often be improved with daily habits. Bring your readings to your next visit.
Why it matters
Over years, pressure in this range makes the heart work harder and can damage blood vessels. Your provider decides with you whether lifestyle changes alone or also medicine are right, based on your overall risk.

Stage 2 hypertension range
What it means
Top number 140 or higher, or bottom number 90 or higher. This is high blood pressure that usually needs a plan with your provider.
Why it matters
Pressure this high raises the risk of heart attack, stroke and kidney problems. Most people in this range are offered medicine along with lifestyle changes.
Everyday steps to discuss with your doctor
Contact your provider soon and share your recent readings.

When to get help now: Call 911 if you also have chest pain, shortness of breath, back pain, numbness or weakness, vision changes, or trouble speaking.
Hypertensive crisis range
What it means
Top number over 180 and/or bottom number over 120. Wait 5 minutes and measure again. If it is still this high, contact your provider right away.
Why it matters
Very high pressure can harm the brain, heart, eyes and kidneys quickly.
Everyday steps to discuss with your doctor
Sit and rest, then recheck after 5 minutes.
When to get help now: Call 911 if you also have chest pain, shortness of breath, back pain, numbness or weakness, vision changes, or trouble speaking.
Blood sugar
Low blood sugar
What it means
Under 70 mg/dL. You may feel shaky, sweaty, confused or hungry.
Why it matters
Low sugar can cause fainting or falls if not treated quickly.
Everyday steps to discuss with your doctor
Rule of 15: eat or drink 15 g of fast sugar (4 oz juice or regular soda, or glucose tablets), wait 15 minutes, recheck.
Tell your provider if lows happen more than once — medicines may need adjusting.
When to get help now: Call 911 if the person passes out, can't swallow safely, or doesn't improve after treatment.
Blood sugar above target
What it means
Over 130 mg/dL before eating, or over 180 mg/dL 1–2 hours after a meal. One high reading happens; a pattern matters more.
Why it matters
Sugar that stays high over months can harm the eyes, nerves, kidneys and heart.
Everyday steps to discuss with your doctor
Keep meals balanced: half the plate vegetables, a quarter protein, a quarter carbs.
A short walk after meals helps lower blood sugar.
Take diabetes medicines as prescribed and note when you check (fasting or after meals).
Bring your log to your visit so your provider can see the pattern.
Blood sugar in target
What it means
80–130 mg/dL before meals, or under 180 mg/dL after meals — the range ADA suggests for most adults.
Why it matters
Staying in range most of the time protects your body long term.
Everyday steps to discuss with your doctor
Keep meals balanced: half the plate vegetables, a quarter protein, a quarter carbs.
A short walk after meals helps lower blood sugar.
HbA1c
Your HbA1c result
What it means
HbA1c shows your average blood sugar over about 3 months. Under 5.7% is normal, 5.7–6.4% is prediabetes, and many people with diabetes aim for under 7%.
Why it matters
Each 1% drop lowers the risk of diabetes complications. Your personal goal may differ.

Keep meals balanced: half the plate vegetables, a quarter protein, a quarter carbs.
A short walk after meals helps lower blood sugar.
Take diabetes medicines as prescribed and note when you check (fasting or after meals).
Bring your log to your visit so your provider can see the pattern.
Heart rate
Your resting heart rate
What it means
60–100 beats per minute at rest is typical. Fit people are often lower. Caffeine, stress, fever or just moving can push it higher.
Why it matters
A heart rate that is often high or low at rest — especially with symptoms — is worth discussing.
Everyday steps to discuss with your doctor
Rest 5 minutes before measuring and note caffeine or activity.
When to get help now: Get help now if a fast or slow heartbeat comes with chest pain, fainting or shortness of breath.
Breathing rate
Your breathing rate
What it means
12–20 breaths per minute at rest is typical for adults.
Why it matters
Fast breathing at rest can be a sign of illness, a lung or heart problem.
Everyday steps to discuss with your doctor
Count breaths for a full 60 seconds while sitting still.
When to get help now: Call 911 for severe trouble breathing or blue lips.
Oxygen
Oxygen below typical
What it means
91–94% is a bit below the typical 95–100%. Warm your hands, sit still and recheck.
Why it matters
Cold fingers, nail polish and movement can give falsely low readings. Readings may also read high on darker skin.
Everyday steps to discuss with your doctor
Tell your provider if readings stay below 95%.
When to get help now: 90% or lower, or trouble breathing: seek care right away.
Temperature
Fever
What it means
100.4 °F (38 °C) or higher. Usually a sign your body is fighting an infection.
Why it matters
Most fevers pass in a few days, but some need care.
Everyday steps to discuss with your doctor
Rest, drink fluids, and call your provider if it lasts over 3 days.
When to get help now: Seek care for 103 °F or higher, a stiff neck, confusion, or trouble breathing.
