You have high blood pressure. You check it often. Then one day, it drops. Maybe it’s 95/60. Maybe 85/55. You feel off. You wonder, is my blood pressure too low?
You’re not alone. This happens to many people. Especially when starting new treatment. Or after big lifestyle changes. Sometimes it’s okay. Sometimes it’s not. Here’s how to know.
What Counts as “Too Low” Blood Pressure?
The normal range is between 90 and 120 systolic, and 60 and 80 diastolic. It is the category of the higher reading that defines the whole reading. Examples: 110/50 is normal, 110/89 is stage 1 hypertension.
Low range is usually under 90/60. That’s a general rule. But for you, with regular high readings, “low” might mean something different.
If you used to have 150/90 every day, and now you’re at 100/60, that’s a big drop. Even though 100/60 is still in the “normal” range, it might feel too low for your body.
Any big change can bring symptoms. Watch for them.
Common Reasons for a Drop
Here are some reasons your blood pressure may drop:
- You started a new medicine.
- You increased your dose.
- You lost weight—10 pounds or more.
- You cut back on salt.
- You exercise more.
- You skipped a meal.
- You didn’t drink enough water.
- You have an infection.
- You’re sick with the flu or a stomach bug.
Even small changes can lower your readings fast. One sweaty workout. One hot day. One missed meal. It adds up.
Signs It’s Too Low for You
Watch your body. Numbers are helpful, but symptoms matter more.
Here are red flags:
- Dizziness
- Feeling faint when standing
- Blurry vision
- Cold hands or feet
- Pale skin
- Nausea
- Weakness
- Chest pain
- Fast or irregular heartbeat
- Confusion
Let’s say your reading 92/58. That might be fine. But if you feel lightheaded, it’s not okay. If you can’t stand without swaying, that number is too low for you.
Is Too Low Reading Dangerous?
Not always. Sometimes, a drop means your treatment is working. Maybe your lifestyle changes are helping. That’s great.
But if you feel dizzy, weak, or faint, it’s not safe. Blood pressure that drops too far can starve your organs of oxygen. That includes your brain and heart.
Low pressure can lead to falls. Or fainting. Or hospital visits. That’s not what we want.
What to Do When Your Blood Pressure Is Too Low
If you feel lightheaded:
- Sit or lie down right away.
- Put your feet up.
- Drink a glass of water.
- Eat something salty (if your doctor allows it).
- Take slow, deep breaths.
Check your blood pressure again in 15 minutes.
Keep a log. Write down:
- The time
- The number
- How you felt
- What you were doing before it happened
Was it after your pill? After a walk? After skipping lunch?
These clues help your doctor.
Check Your Medications
Are you on:
- A diuretic (water pill)?
- Losartan?
- Amlodipine?
- Metoprolol or another beta blocker?
- ACE inhibitors?
These can all lower your readings. Especially in the first weeks. Or if the dose is too high for you.
Never stop a medicine on your own. Talk to your doctor. You may need a lower dose. Or a different timing. Or just more water in your day.
When to Call for Help
Call your doctor if:
- Your blood pressure is under 90/60 for more than a few days
- You keep feeling dizzy
- You fainted
- You fell
- Your blood pressure drops below 80/50
- You have chest pain
- Your heart races or skips
- You feel confused or very tired
Don’t wait. It’s better to check in early than to risk a fall or worse.
Final Thoughts
It’s good that your blood pressure is lower. That may be a sign of progress. But it must feel safe too. You should not feel dizzy or weak every day.
Watch your numbers. Watch your body more.
Log your readings. Share them with your doctor.
Ask questions. Be honest about how you feel.
You’ve done the hard work to bring your blood pressure down. Make sure it stays at the right level for you.
Lower is not always better. Safe is best.
