You turn onto your left side in bed, and the ceiling swings. It lasts a few seconds. Then it stops, and you lie very still, wondering what just happened.
Or it is the sofa. You push up to answer the door, and a gray wash comes over your vision. You grab the armrest. Twenty seconds later you are fine.
Those two moments feel similar. They are not the same problem. One starts in your inner ear. The other starts in your blood pressure. A third kind of dizziness is neither. It shows up as a constant wobble that never quite goes away.
This article is a sorter, not a treatment plan. By the end you should know which of the three patterns fits you, and who to see first.
Most dizziness is not dangerous. A small amount of it is a stroke, and older adults are the group most at risk. So please read this part before anything else.
The Centers for Disease Control and Prevention lists these stroke warning signs: "Sudden trouble walking, dizziness, loss of balance, or lack of coordination. Sudden trouble seeing. Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body. Sudden confusion, trouble speaking, or difficulty understanding speech. Sudden severe headache with no known cause."
The CDC memory aid is B.E. F.A.S.T. Balance loss. Eye or vision changes. Face drooping on one side. Arm drifting down when both are raised. Speech slurred or strange. Time to act.
Dizziness that arrives together with any of those other signs is the pattern to worry about. So is dizziness that comes on suddenly and does not settle.
The CDC instruction is direct: "Call 9-1-1 right away if you or someone else has any of these symptoms." And: "Do not drive to the hospital or let someone else drive you."
If you are unsure, treat it as an emergency. Nothing in the rest of this article outranks that.
Clinicians do not sort dizziness by how bad it feels. They sort it by pattern. Three questions do most of the work.
What set it off? Did it start when your head changed position, or when your body stood up, or did it come for no clear reason?
How long did it last? Seconds, under a minute, a few minutes, or all day?
What came with it? Nausea, a spinning room, a gray faint feeling, ringing in the ear, or nothing except unsteadiness?
Hold those three answers in mind as you read the next three sections. Most people see themselves in one of them.
If two of them fit you, that is fine too. It happens more often than you would think, and we come back to it later.
Benign paroxysmal positional vertigo, usually shortened to BPPV, is an inner ear problem. Tiny crystals that normally sit in one part of the inner ear drift into a part where they do not belong. When you move your head, they move, and your brain gets a signal that you are spinning when you are not.
The pattern is very specific. StatPearls describes BPPV as "brief, recurrent episodes of vertigo precipitated by changes in head position relative to gravity," lasting "less than 1 minute."
Note the trigger. It is a change of head position, not a change in body posture. Common triggers listed are "rolling over in bed, looking upward, or bending forward."
So the classic story is rolling over in bed. Or tipping your head back to reach a high shelf. Or lying down flat at the dentist.
The feeling is true spinning. The room moves, or you move, and there is no mistaking it. Many people feel sick with it.
And it stops. Hold your head still and the spinning settles within seconds. That short burst, which ends on its own, is the single most useful clue.
BPPV is not rare in our age group. StatPearls notes it "most often begins in the fifth to seventh decades of life," and reports a one year prevalence of 1.6 percent with an annual incidence of 0.6 percent. It is more common in women, with reported female to male ratios between 2.2 to 1 and 1.5 to 1.
The good news is that BPPV responds well to a specific in-person treatment. We cover that in detail on our BPPV and vertigo treatment page.
Orthostatic hypotension is a drop in blood pressure when you stand up. Gravity pulls blood toward your legs, and for a moment your brain gets less than it needs.
The agreed definition is precise. StatPearls describes it as "a sustained drop in systolic blood pressure (SBP) of at least 20 mm Hg or diastolic blood pressure of 10 mm Hg within 3 minutes of standing after being supine for at least 5 minutes."
The trigger here is standing up, not turning your head. You can roll over in bed all night without a symptom, then get light headed the moment you rise.
The feeling is different too. People describe gray vision, a faint or floaty head, weak legs, or a head that seems far away. It is usually not a spinning room. StatPearls lists the symptoms as "Lightheadedness, dizziness, or syncope" along with falls.
It also stops in a telltale way. "Symptoms of orthostatic hypotension are triggered by postural changes and typically resolve when sitting or lying down." Standing still for a moment, or sitting back down, tends to end it.
Timing is worth knowing, because the drop comes in three patterns. The initial type "lasts less than 15 seconds after postural changes." The classic type "occurs within 3 minutes of standing." The delayed type "occurs after 3 minutes of standing."
This one is common after 60. StatPearls reports that "1 in 5 adults aged 60 or older living in the community experience orthostatic hypotension," and "over 25% of individuals aged 85 and older."
Here is the part that gets missed most often. A long list of ordinary prescriptions can cause or worsen this.
StatPearls names alpha-blockers, antihypertensives, diuretics, nitrates, tricyclic antidepressants, selective serotonin reuptake inhibitors, antipsychotics and beta-blockers.
That is a lot of common medicine. If your dizziness started within a few weeks of a new prescription or a dose change, write that down and bring it up. Do not stop or change a dose on your own.
Non-drug steps in the same chapter include "Gradually changing position in phases (from lying to sitting to standing) rather than abruptly," "Maintaining adequate hydration," compression stockings or binders, and "Avoiding alcohol, warm environments, large meals, and hot showers."
This matters because falls follow. StatPearls states that "Orthostatic hypotension is associated with a high rate of morbidity and mortality, primarily due to frequent falls."
The third pattern is the one people struggle to name, because it often is not a spin at all.
Vestibular hypofunction means the balance organ in one or both inner ears is not sending a full signal. We will call it a weak inner ear signal from here on, because that is what it is.
Your brain still gets news from your eyes and your feet. So on a bright day, on a flat sidewalk, you may be fine.
Take away those other inputs and you wobble. The American Physical Therapy Association guideline describes the core symptoms as "dizziness, imbalance, and/or oscillopsia," and notes that people report "difficulty walking in the dark and on uneven surfaces."
Oscillopsia is worth translating. It means the world seems to bounce or jitter when you move your head, so reading a street sign while walking becomes hard.
Recognize any of these?
That slow timeline is the giveaway. BPPV arrives in seconds. A blood pressure drop arrives on standing. This one arrives over a season, and it does not switch off when you hold still.
It is also common. The APTA guideline states that "It is estimated that one-third of adults in the United States have vestibular dysfunction and the incidence increases with age."
That estimate traces to a national survey. Agrawal and colleagues analyzed National Health and Nutrition Examination Survey data from 2001 to 2004 and found that "35.4% of US adults aged 40 years and older (69 million Americans) had vestibular dysfunction." Participants with symptoms had "a 12-fold increase in the odds of falling."
Read that last figure carefully. NHANES is a cross-sectional survey, which means it looks at a population at a single point in time. It shows a strong link between symptoms and falls. It does not prove one caused the other.
If this third pattern sounds like you, our post on vestibular physical therapy for dizziness in older adults goes deeper than we can here.
Three patterns cover a lot of ground. They do not cover everything. These others are real, and each is worth its own talk with a clinician:
None of these is something to sort out alone. Bring the pattern to someone who can test for it.
| BPPV (inner ear crystals) | Blood pressure drop on standing | Weak inner ear signal and balance loss | |
|---|---|---|---|
| What triggers it | A change of head position: rolling over, lying down, looking up, bending forward | Standing up from lying or sitting | Often no single trigger. Worse in the dark, on uneven ground, in busy visual places |
| How long an episode lasts | Under a minute, usually seconds | Under 15 seconds to about 3 minutes, by type | A constant background wobble rather than episodes |
| What it feels like | True spinning, often with nausea | Gray, faint, light headed, weak legs | Unsteady, floating, or the world bouncing when you move your head |
| What usually settles it | Holding the head still | Sitting or lying back down | Nothing settles it quickly. It eases on a flat, bright, familiar surface |
| Who to see first | Physical therapist or physician who treats BPPV | Your physician or prescriber, for a blood pressure and medicine review | Physical therapist trained in inner ear care |
You may have read about the Dix-Hallpike maneuver or the Epley maneuver. Please do not try either on yourself.
Both involve dropping your head backward and rotating it quickly. If you guess the wrong ear or the wrong maneuver, you can trigger violent vertigo while unsupported. That is a fall waiting to happen, and there is no one there to steady you.
Here is something safer, and far more useful. Keep a one week dizziness diary. Every time it happens, write down four things:
Add a note for any new medicine or dose change in the past month.
Use the notes app on your phone, or a pad by the bed. Either one works. The point is to write it down while it is fresh, not days later when the details have gone soft.
That record is worth more to a clinician than any maneuver you try alone. It captures the exact three things the sorting rests on: trigger, duration and company.
One more thing you can arrange rather than attempt. Ask your physician, clinic nurse or pharmacist to check your blood pressure lying down and then standing. StatPearls describes taking readings "at 1, 2, and 3 minutes after transitioning from sitting to standing." That is a staffed, seated-nearby check, not a solo project.
Two expert guidelines carry most of the weight here. Both of them give advice that protects you from tests and drugs you do not need.
The American Academy of Otolaryngology, Head and Neck Surgery Foundation updated its BPPV guideline in 2017. It made 14 recommendations.
It made strong recommendations that clinicians should "diagnose posterior semicircular canal BPPV when vertigo associated with torsional, upbeating nystagmus is provoked by the Dix-Hallpike maneuver," and should "treat, or refer to a clinician who can treat, patients with posterior canal BPPV with a canalith repositioning procedure."
In plainer terms: a trained clinician moves your head in a set sequence to see the response, then moves it in another set sequence to guide the crystals back. Both happen with someone beside you.
Now the two that protect you. The guideline made recommendations against "radiographic imaging for a patient who meets diagnostic criteria for BPPV" when nothing else about the picture calls for a scan. It made the same kind of statement against "vestibular testing" in that same case.
And it made a recommendation against "routinely treating BPPV with vestibular suppressant medications such as antihistamines and/or benzodiazepines."
That last one surprises people. Those drugs dull the feeling without treating the cause. The guideline's stated purpose includes "reducing the inappropriate use of vestibular suppressant medications, decreasing the inappropriate use of ancillary testing such as radiographic imaging."
The guideline also lists options, which is a weaker grade. Clinicians may offer observation with follow-up, and may offer "vestibular rehabilitation, either self-administered or with a clinician, in the treatment of BPPV."
Two more points matter for our readers. Clinicians should assess patients "for factors that modify management, including impaired mobility or balance, central nervous system disorders, a lack of home support, and/or increased risk for falling." And they should reassess "within 1 month."
The Academy of Neurologic Physical Therapy of the American Physical Therapy Association published an updated guideline in 2022, built on a systematic review that identified 67 relevant articles, searching the literature from 2015 through June 2020.
Its wording is unusually firm. "Clinicians should offer VPT to individuals with acute or subacute unilateral vestibular hypofunction (evidence quality: I; recommendation strength: strong)." VPT there means vestibular physical therapy. The same strong rating applies when both inner ears are affected.
It speaks to supervision head on: "Clinicians should offer supervised vestibular physical therapy in individuals with unilateral or bilateral peripheral vestibular hypofunction (evidence quality: I; recommendation strength: strong)."
There is a clear do-not in there as well. "Clinicians should not offer saccadic or smooth-pursuit exercises as specific exercises for gaze stability to individuals with unilateral or bilateral vestibular hypofunction (evidence quality: I; recommendation strength: strong)." Eye movements alone, without head movement, are not the thing that works.
On dose, the guideline describes gaze stability exercises "3 to 5 times per day for a total of at least 20 minutes daily for 4 to 6 weeks" when one inner ear is affected long term. When both are affected it describes "3 to 5 times per day for a total of 20 to 40 minutes daily for approximately 5 to 7 weeks."
Those are guideline ranges for a known, tested cause. They are not a promise about your case.
If you have never done this, here is the shape of a first visit. Our what to expect at your first visit post covers the general version.
The history comes first, and it is long. This is where your diary earns its keep. Expect close questions about the trigger, how long it lasts, and what comes with each episode.
A medicine review. Every prescription, every supplement, every recent dose change.
Eye and head movement testing. Your therapist watches your eyes while your head moves in set ways. Tiny eye movements you cannot control tell them a great deal.
Position testing, done by the therapist. If the history points to BPPV, they will guide your head through the set positions, with hands on you and a plan for what comes next.
Balance and walking checks. Standing with feet together, standing with eyes closed, walking while turning your head, walking on a softer surface.
Blood pressure, sitting and standing, if the story suggests it.
A plan, in writing, with a goal and a review date.
We would rather tell you this than have you find out after three visits.
Physical therapy treats BPPV well, and it treats a weak inner ear signal well. Both guidelines above back that up, and the repositioning treatment for BPPV carries a strong rating.
Physical therapy does not treat a blood pressure problem. If your dizziness is the drop on standing, the useful work is a medicine review and a check-up with your physician. We can help with the fall risk that comes with it, and with safe ways to move, but we are not the right first stop for the cause.
Physical therapy does not treat a heart rhythm problem either. Dizziness with palpitations, chest discomfort or fainting belongs with a physician promptly.
And no honest therapist will promise you a cure. What a good plan gives you is a clear cause, treatment matched to it, and a set date where you both check whether it is working.
One note on our equipment, since people ask. HWY uses a Neubie, an FDA-cleared direct current device that is not a TENS unit, and we are the only clinic in Salem with one. It is not a treatment for dizziness or vertigo, we will not use it for that, and it belongs to other topics entirely.
Many people find this article while worrying about someone else. A few things help.
Start by knowing that you are not being pushy. Dizziness is easy to hide and easy to shrug off, and a second pair of eyes catches what the person living with it stops noticing.
Ask about the pattern, not the feeling. "Does the room spin, or do you go gray?" gets you further than "are you dizzy?" So does "does it happen when you turn your head, or when you stand up?"
Bring the medicine list to every visit. The actual bottles, not a list from memory. The prescriber may not know what everyone else has prescribed.
Watch for what they have stopped doing. People hide dizziness by shrinking their lives. Skipping the evening walk, avoiding the stairs, or taking the elevator for one floor are all signals.
Keep the diary for them if they will not. A week of notes changes a visit completely.
If unsteadiness is the bigger worry, our post on an aging parent who is unsteady on their feet is written directly for you.
Can I fix this at home with a video I found online?
Please do not. These maneuvers need to know which ear and which canal is involved, and that needs someone watching your eyes while your head moves. Guessing wrong can make you much dizzier with nothing to hold. A clinician can do it in minutes, with a plan for what comes next.
Do I need a scan or an MRI?
Not for straightforward BPPV. The AAO-HNS guideline recommends against "radiographic imaging for a patient who meets diagnostic criteria for BPPV" when nothing else about the picture calls for it. A scan is right when the picture does not fit, and that call belongs to a clinician who has examined you.
My doctor gave me a pill for dizziness. Should I take it?
Follow your physician's advice, and ask about this specific point. The AAO-HNS guideline recommends against "routinely treating BPPV with vestibular suppressant medications such as antihistamines and/or benzodiazepines." Those drugs dull symptoms rather than treat the cause. That is a talk to have, not a reason to stop a prescription.
Can I have more than one cause at once?
Yes, and after 50 it is common. Someone can have crystals in the inner ear, a blood pressure drop from a new prescription, and slow age-related balance loss all at the same time. That is exactly why a diary that records each separate episode is so useful.
How long until I feel different?
It depends on which cause you have. BPPV treated with a repositioning move can change fast, and the AAO-HNS guideline calls for a recheck within one month. A weak inner ear signal takes longer. The APTA guideline describes exercise programs running 4 to 6 weeks for long standing cases in one ear, and 6 to 9 weeks when both ears are involved. Those are guideline ranges, not a forecast for you.
Can you do this by video?
Partly. A first dizziness check is better in clinic, because position testing needs hands on you and someone watching your eyes closely. A video visit is a good way to go through your diary, talk through the pattern, and decide whether you need to come in at all. That is what our Wellness Video Call is for.
Dizziness is scary because no one else can see it, and it comes without warning. But it is also one of the easiest symptoms to sort, and you already hold most of what is needed to sort it.
Watch what triggers it. Time how long it lasts. Note what comes with it. Then take that week of notes to someone who can act on it.
If you are in Salem and you want help reading your own pattern, book a Wellness Video Call with Dr. Raj Pusuluri, PT, DPT. We will go through your diary, tell you honestly which of the three patterns fits, and tell you just as honestly if the right next call is to your physician instead of to us.
