Understanding Dizziness
Understanding Your Dizziness
Dizziness is feeling woozy, floaty, or unsteady on your feet. It often occurs when changing positions or starting medications. Common causes include blood pressure fluctuations, dehydration, and inner ear changes.
How Patients Commonly Describe the Sensation:
- Feeling lightheaded or faint when standing up from a chair or bed (postural dizziness)
- A floaty, woozy sensation when walking through busy environments or under bright lights
- Brief dizziness that occurs an hour or two after taking blood pressure medications
- Unsteadiness paired with a feeling of warmth or mild nausea
How It Develops
It often occurs when changing positions, starting new blood pressure medication, or in warm weather.
What It Means
Your blood pressure regulation needs fine-tuning. Simple adjustments quickly restore your balance.
What Could Be Causing It?
A Reassuring Note for Patients
Occasional lightheadedness upon standing quickly is very common and usually easy to fix. In many cases, it simply means your blood pressure medication is working a little too well and needs a minor adjustment.
Everyday & Non-Cardiac Factors
Cardiovascular & Vascular Conditions
Finding the Cause
Cardiovascular testing evaluates how your blood pressure and heart rate respond to positional changes and daily activities.
Diagnostic tests include:
Orthostatic (Lying & Standing) Blood Pressure Check
Measures blood pressure and pulse lying down, after 1 minute standing, and after 3 minutes standing.
24-Hour Ambulatory Blood Pressure Monitor (ABPM)
Records blood pressure every 20 minutes to pinpoint exact times when pressure dips or surges.
12-Lead ECG & Holter Monitor
Rules out intermittent slow heart rates (bradycardia) or rhythm pauses coinciding with dizzy spells.
And more, when clinically appropriate
We use additional diagnostic tools based on your symptoms, clinical findings, and individual risk profile.

What Can Help?
Practical Daily Measures
Pause before standing: sit on the edge of the bed for 30 seconds before rising to full standing height.
Drink a glass of water before getting out of bed in the morning to support blood volume.
Do not stop or change your blood pressure medications without speaking with your doctor first.
Perform simple leg crossing and calf contraction exercises before standing up to pump blood upward.
What You Should Monitor

When to Arrange Assessment
Schedule a cardiology appointment if dizziness happens frequently, if you feel near-faint, or if you suspect your blood pressure medications need adjusting.
