Blood pressure worries: what to do next

Blood pressure can be confusing—especially when numbers bounce. This page helps you measure correctly, focus on trends, and know when to call for help.

Section: Common Issues

The most helpful first step If you’re worried about blood pressure, take good measurements at home for 5–7 days. A single high reading is information—not a verdict.

Step 1: Measure correctly (it changes the result)

Sit quietly for 5 minutes first.
Back supported, feet on the floor, arm supported at heart level.
Use the right cuff size (too small = falsely high).
Take 2 readings, 1 minute apart, and write both down.

Step 2: Look for patterns (not perfect numbers)

Higher in the clinic? “White coat” effect is common.
Higher in the morning? sleep quality, stress, or timing of meds may matter.
Spikes after salty meals? very common.

When to call your clinician soon

Readings are repeatedly high over several days
You feel dizzy when standing (possible low BP / medication effect)
You started a new medication or changed doses recently

Emergency warning signs

Chest pain, shortness of breath
Severe headache with confusion or weakness
New one-sided weakness, face droop, speech trouble
Fainting

Questions that lead to clear answers

“Do you want home readings, and what’s the best way to send them?”
“What is our target range for me?”
“Could any of my meds (including pain meds) affect BP?”
“Should we screen for sleep apnea?” (it can affect BP)

Ask your clinician (starter questions)

“What serious causes are we ruling out?”
“Could any of my medications or supplements contribute?”
“What is the simplest next step or test?”
“What can I safely do at home while we figure this out?”
“What symptoms should make me call you sooner or get urgent care?”
