Dizziness in Older Adults: Why It Happens and What Can Be Done

You would be surprised how many older patients sit across from me and say they have been dizzy for weeks, assuming it would sort itself out. Sometimes it does. More often, something fixable is being missed. If you or someone you care for has dizziness that keeps coming back, that is not something to wait out.

The first real concern with dizziness in people over 65 is falls. Falls at that age can mean fractures, hospital stays, and a long recovery. But beyond fall risk, dizziness is usually a signal. Something is off with the inner ear, the blood pressure, or the medications. In rare cases, it points to the heart or brain. Getting that answer is straightforward once you are in front of a doctor.

What Older Adults Actually Feel — And Why It Matters

The way you describe the dizziness tells me a lot before I have even examined you.

Some people feel like the room is spinning. That is vertigo, and it usually points to the inner ear. Others feel lightheaded, like they might faint, especially when standing up quickly. That points toward blood pressure. Some feel unsteady on their feet, as if the ground is shifting beneath them. A fourth type is that near-fainting sensation before everything briefly dims. That one always warrants a heart and blood pressure check.

Getting this distinction right shapes what tests I run and what I look for first.

Age-Related Changes That Affect Balance

Balance relies on three systems working together: the inner ear, vision, and the body’s sense of its own position. With age, all three gradually decline. When they decline at the same time, the effect compounds.

The inner ear loses sensory cells over decades. Vision becomes less reliable in low light. Nerve signals from the feet slow down, making it harder for the brain to track where the body is in space. This is not a disease. It is the accumulated effect of ageing on a system that was never designed to be perfect.

It explains why some older adults feel unsteady even without one dramatic diagnosis. The answer is still a proper clinical assessment, not a shrug.

The Most Common Causes of Dizziness in Elderly Adults

Benign Paroxysmal Positional Vertigo

BPPV is the most common cause I see. Tiny crystals in the inner ear shift out of place and send false signals to the brain. The result is a sudden intense spinning triggered by rolling over in bed, tilting the head back, or looking up. It usually lasts under a minute, then fades, and returns with the next head movement.

BPPV responds very well to treatment. A specific head movement sequence called the Epley manoeuvre can resolve it in one or two sessions for most patients. No medication needed. You just need a doctor who knows how to do it.

Orthostatic Hypotension

This is the dizziness that hits when you stand up. Blood pressure drops briefly because the body is slower to compensate in older age. It lasts a few seconds to a minute. In mild cases it is a nuisance. In moderate cases it causes falls.

Dehydration makes it significantly worse. So do several common medications. If this is happening daily, it needs to be assessed, not accepted.

Meniere’s Disease and Other Inner Ear Conditions

Meniere’s disease causes episodes of intense vertigo, often paired with ringing in the ear and reduced hearing on one side. Episodes can last twenty minutes to several hours. Vestibular neuritis is an inner ear inflammation, often following a viral illness, that causes sustained vertigo lasting days. These conditions are less common than BPPV but more disruptive, and they do require specific management.

Medications as a Hidden Cause of Dizziness in Older Adults

This is the section most patients do not expect. A significant number of older adults who come to me dizzy are, in part, dizzy because of their own medications.

Blood pressure drugs, water tablets, sedatives, some antidepressants, and certain antibiotics can all cause or worsen dizziness. Others lower blood pressure too much, especially in warm weather. Managing four or more medications at once multiplies the risk.

I see this often with expats who have prescriptions from their home-country doctor and no local physician reviewing them. A different climate, a different diet, and a more or less active lifestyle can all change how a medication behaves in the body. If you have not had your medications reviewed since arriving in Bangkok, that is worth doing.

Bangkok-Specific Risk Factors: Heat, Humidity, and Dizziness in Older Adults

Bangkok’s heat is not a minor consideration. Temperatures regularly exceed 35 degrees Celsius with high humidity. That accelerates fluid and electrolyte loss, especially in older adults whose thirst response is already blunted. Low sodium and dehydration can cause significant lightheadedness, and both worsen orthostatic hypotension.

If an older visitor or expat is dizzy in Bangkok, dehydration is always on my list. Increased fluids help, but if someone is also on diuretics or has not been eating well, electrolytes need to be checked. At Doctor Bangkok, we can run that blood panel the same day and have a clear picture within hours.

Serious Causes That Must Not Be Missed

Most dizziness in older adults is not dangerous. But some of it is, and knowing the difference matters.

A transient ischemic attack, sometimes called a mini-stroke, and a full stroke can both present with dizziness. So can abnormal heart rhythms that cause sudden drops in blood flow to the brain. Narrowed blood vessels supplying the brain can cause chronic unsteadiness.

The red flags to act on immediately are sudden severe dizziness combined with any of the following: double vision, slurred speech, facial drooping, weakness on one side, sudden severe headache, or loss of coordination. Any of those combinations means go to an emergency department now. Do not wait to see if it passes.

BPPV causes brief spinning triggered by head position changes. Stroke-related dizziness tends to be sudden, persistent, and comes with neurological signs. If you are not sure which one you are looking at, come in. Doctor Bangkok can assess, run an ECG, and refer urgently if needed.

What a Dizziness Assessment Looks Like at Doctor Bangkok

A lot of patients put off coming in because they do not know what to expect. Here is what actually happens.

I take a full history: when it started, what triggers it, how long it lasts, and what else comes with it. I check blood pressure lying down and standing. I check heart rate. For suspected BPPV, I do a positional test called the Dix-Hallpike, which reproduces the vertigo if the inner ear is the cause. I run a blood panel checking for anaemia, blood sugar, electrolytes, and kidney function. If a cardiac cause seems possible, I add an ECG.

Imaging is not always needed. I order it when the history or examination raises concern about a central cause. Consultations are in English, and no referral letter is required to walk in.
