Dizziness or Vertigo? The Word You Use Changes the Investigation
Reading time: about 7 minutes. Written for anyone who has said "I get dizzy" in an appointment and watched it land as nothing in particular.
You say dizzy. The person opposite you writes down dizzy. And that single word has just sent your investigation in one of four completely different directions, because in clinical terms it does not mean one thing. It means four, and they point at different systems, different specialties and different tests.
This is not about using impressive words. It is about the fact that describing the sensation accurately is often what decides whether anything gets looked into at all.
🌿 The answer to "when does it happen?" is not something you can reconstruct
Only on standing, or also sitting? Worse in the morning? Only in the heat? Those answers decide as much as the word you choose. Our free Daily Wellness Tracker is one line a day, so the pattern already exists by the time someone asks.

🧭 The four things "dizzy" can mean
Clinicians generally sort dizziness into four categories. They are not subtle variations on the same feeling. They are different sensations with different mechanisms, and telling them apart is the first thing an assessment tries to do.
1. Lightheadedness
The sensation that you might faint. Often described as everything going far away, sounds becoming muffled, vision greying or narrowing at the edges, a wave of heat or clamminess. The room is not moving. You are the one about to go.
This is the one most associated with blood pressure and blood flow, and it is the one most people with orthostatic intolerance are describing.
2. Presyncope
The more specific end of the same family: the clear sense that you are about to lose consciousness, sometimes with the symptoms above arriving fast. It is worth naming separately because it is a stronger signal, and because how often it happens matters clinically.
3. Vertigo
A false sense of movement. Either you are spinning, or the room is. Not a general fuzziness, not a wobble: an illusion of motion when nothing is moving. It often comes with nausea, and it may be triggered by turning your head or rolling over in bed.
This is a genuinely different symptom, and it usually points towards the inner ear or the balance pathways rather than towards blood pressure.
4. Disequilibrium
Unsteadiness on your feet, without the head sensation at all. Veering into door frames, needing to touch walls, feeling like the ground is unreliable. Your head feels normal, your balance does not.
This one gets overlooked constantly, because people file it under clumsiness rather than reporting it. It is also the one most likely to relate to proprioception, which we cover in why you bump into everything.

🔀 Why the word changes what happens next
Here is the practical consequence, and it is the whole reason this article exists.
Say "vertigo" and you are likely to be sent down an inner ear pathway. Balance testing, possibly an ear, nose and throat referral, positional manoeuvres. All entirely appropriate if the room genuinely spins.
Say "lightheaded on standing" and you are describing something measurable in the room, with a blood pressure cuff and a pulse. That is a different conversation, and it is the one that leads towards orthostatic assessment.
If those two get swapped, you can spend a year in the wrong clinic. It happens often enough that it is worth being deliberate about which word you use, and worth correcting the record if the wrong one was written down.
💚 You are allowed to correct it
If a letter or a note says vertigo and what you actually get is the greying-out kind, that is worth flagging plainly at the next appointment. Not as a complaint, just as a correction: "the notes say vertigo, but the room doesn't spin, it's more that I feel like I'm about to faint." One sentence, and it can redirect an entire investigation.
🕐 The second half of the description: when
The sensation is half the information. The circumstances are the other half, and they are often what makes a pattern recognisable.
Only on standing, or also when sitting and lying? Symptoms that resolve when you lie down and return when you stand up point somewhere quite specific.
Immediately, or after a few minutes upright? A brief moment on standing and a slow build over ten minutes are different observations.
Triggered by head position? Rolling over in bed, looking up at a shelf. That pattern belongs to the vertigo family.
Worse in the heat, after meals, or before your period? All three are recognised patterns worth mentioning, and all three are covered elsewhere on this site.
How often, and how long each time? Seconds, minutes or hours changes the picture entirely.
None of that survives being reconstructed in a waiting room, which is exactly why a fortnight of one-line notes is worth more than a careful description given from memory.
🩺 What to actually say
A sentence with three parts does most of the work: the sensation, when it happens, and what it stops you doing.
Rather than "I get dizzy a lot", something closer to:
"It's not spinning. It's more that everything goes grey and far away, and it happens within a couple of minutes of standing up, most days. I have to sit down on the floor in shops."
That version contains a category, a trigger, a frequency and an impact. It is roughly the same number of words, and it is a completely different piece of information.
🌿 Two weeks of one-line notes beats any description from memory
Which sensation, when it happened, how long it lasted, what you were doing. That is the record that turns "I get dizzy" into something a clinician can work with. One line a day is enough.

🚨 When dizziness needs urgent attention
Most dizziness is not an emergency. Some is. Seek urgent medical help if dizziness or vertigo arrives suddenly and severely, or comes with any of the following:
Weakness or numbness on one side, drooping of the face, difficulty speaking or understanding speech, sudden severe headache unlike your usual, double vision or loss of vision, chest pain, difficulty breathing, a fall with a head injury, or fainting that you cannot explain.
These are not signs to track and mention next month. They are reasons to contact emergency services or urgent care now.
❓ Frequently asked questions
Is dizziness the same as vertigo?
No. Vertigo is a false sense of movement: you or the room spinning when nothing is moving. Dizziness is a broader word that also covers lightheadedness, the sense of being about to faint, and unsteadiness on your feet. The distinction matters because the categories point towards different systems and different assessments.
What if I have more than one kind?
That is common, and it is worth saying so rather than picking one. "Mostly the greying-out kind when I stand, but occasionally the room genuinely spins when I roll over in bed" is more useful than either half on its own, because two patterns may have two different explanations.
Why does it matter which word I use?
Because the word tends to determine which pathway you are sent down. Vertigo usually routes towards inner ear and balance assessment. Lightheadedness on standing routes towards measuring your blood pressure and heart rate in different positions. If the wrong word is recorded, the wrong investigation follows, and that can cost months.
Can I be assessed if it doesn't happen during the appointment?
Yes. Much of the assessment rests on your description, your pattern and observations that can be taken in the room. This is exactly why a written record of when it happens is so useful: it substitutes for a symptom that rarely turns up on cue.
Should I stop driving?
That depends on your symptoms and, in many places, on rules about reporting certain conditions. It is a question for your doctor rather than for an article, and it is worth raising directly rather than waiting to be asked. There is more on the specific risks in our guide to driving with POTS.
What if I've already been told it's anxiety?
That happens, and it does not close the question. Describing the sensation precisely, along with when it occurs and what it stops you doing, is the most useful thing you can bring back. Our guide to POTS and anxiety covers what separates them.
