Dizzy When Standing Up: What to Do

You watch your mum or dad push themselves up from the sofa, and for a second their eyes go glassy. They grab the armrest and wave you off. “I’m fine, just stood up too fast.” It happens again the next day. And the day after that.

That dizzy spell when standing up has a name and a reason. More importantly, there are real things you can do about it — without alarm, and without taking over someone’s independence.

What is actually happening in the body

When a person stands up, gravity pulls blood downward, away from the brain. Normally the body corrects this in a heartbeat — blood vessels tighten, the heart beats a little faster, and blood pressure stays steady. In some people, that correction is too slow. Blood pressure dips before the body catches up, and for a few seconds the brain gets slightly less blood than it needs. That is the dizzy moment.

Doctors call this orthostatic hypotension — “orthostatic” meaning related to standing, “hypotension” meaning low blood pressure. It is defined as a drop in blood pressure of 20 points or more (on the top number) or 10 points or more (on the bottom number) within three minutes of standing. Alongside dizziness, it can cause light-headedness, blurred vision, a sense of unsteadiness, weakness, or nausea.

How common is this, and who does it affect most

About one in five older adults living in the community experiences this — compared with roughly one in twenty middle-aged adults. So if it is happening to someone you love, they are far from alone.

Several things can make it more likely. Certain medicines are a very common cause. So are conditions like diabetes, heart disease, thyroid problems, nerve damage, or issues with blood vessels. Problems with vision and balance also play a role. That is a wide list, which is exactly why it is worth talking to a doctor rather than simply accepting it as part of getting older.

One common misunderstanding is that this is just ageing doing its thing. It is not. Orthostatic hypotension is a frequently undiagnosed condition. When it happens regularly, it is associated with reduced quality of life and a higher risk of falls, stroke, and dementia. That does not mean panic — it means it deserves proper attention.

The real danger: falling when no one is there

The dizziness itself passes quickly. The danger is what can happen in those few seconds, especially for someone living alone. A stumble in the hallway at midnight, a grab for something that is not solid enough, a fall in the bathroom — these are the moments that change everything.

A few practical changes to the home can make a meaningful difference. Night lights along the route from the bedroom to the bathroom are worth installing. Grab bars in the bathroom and near the toilet give something reliable to hold. If a cane or walking frame has been recommended by a doctor, using it consistently matters most on those first few steps after standing.

Strength and balance exercises — done regularly, ideally with guidance from a physiotherapist — also reduce the risk of a fall when a dizzy spell does happen. The goal is a body that can catch itself.

What to do in the moment dizziness strikes

The single most important thing is to stand still. Not to walk, not to reach for something across the room. Just stop and hold on until the moment passes. Moving quickly is when falls happen.

There are also specific movements, backed by research, that help the body recover faster. Leg crossing — crossing one leg over the other while standing — tightens the muscles in the legs and pushes blood back upward. Leg pumping — rising up and down on the toes, or tensing and releasing the calf muscles — does the same. Bending forward slightly has also been shown to help. These are not folk remedies; they are recommended in current clinical guidelines as a first response.

Taking a moment before standing up also helps. Sitting on the edge of the seat for a few seconds, rather than going straight from lying or sitting to fully upright, gives the body a chance to start adjusting before the full challenge of standing.

Everyday habits that make a difference

Staying well hydrated matters more than many people realise. When the body is low on fluids, blood pressure is harder to maintain, and dizzy spells become more likely. Plain water throughout the day — not just at mealtimes — is a straightforward habit to build in.

Alcohol makes this worse. It widens blood vessels, which makes blood pressure drop more sharply when standing. Heat does the same thing — a very hot bath or shower, or a hot day, can trigger episodes in someone who barely notices the problem otherwise.

Compression stockings — tight socks or stockings that squeeze the legs gently — are recommended in current guidelines as a first-line, non-medicine approach. They reduce the amount of blood that pools in the legs when standing. They need to be properly fitted and worn consistently to help, so it is worth asking a doctor or nurse about the right type.

Medicines: the overlooked piece

Medication is one of the most common and most overlooked causes of dizziness when standing up. Blood pressure medicines, water tablets (diuretics), medicines for the heart, some antidepressants, and several other drug types can all contribute. This is especially true when a person is taking several medicines at once — something doctors call polypharmacy.

As a family member, one of the most useful things you can do is make sure the GP has a full picture. Write down every medicine the older adult takes, including anything bought over the counter, and bring that list to the appointment. Ask the doctor directly whether any of those medicines could be contributing, and whether the dose or the medicine itself could be reviewed. Do not stop or change any medicine without talking to the doctor first — but do ask the question.

It is worth knowing that when medicines are the cause, adjusting them can make a substantial difference. This is not about removing treatment; it is about making sure the treatment is working as well as it can without unnecessary side effects.

When to get help

Most episodes of dizziness when standing up are brief and settle on their own. These situations are different and need prompt attention:

• Loss of consciousness — if the person faints or blacks out, even briefly, seek same-day medical advice.
• Dizziness that is new and severe — a sudden, strong dizziness that feels different from before.
• Chest pain alongside the dizziness — call emergency services.
• Weakness or numbness on one side of the body — call emergency services immediately.
• A sudden, very severe headache — one that feels unlike any headache before — call emergency services.
• Dizziness that does not pass — if the feeling does not settle within a minute or two of standing still, get help.
• Regular episodes or a near-fall — even if each episode resolves on its own, recurring dizziness when standing deserves a proper conversation with a GP.

These signs can point to causes that go beyond orthostatic hypotension and need urgent assessment.

A final word

A dizzy spell when standing up is easy to brush off. It passes quickly, it feels embarrassing to mention, and it is tempting to assume it is just part of getting older. It is not something to accept without question.

The good news is that there are real, practical steps — changes to how a person stands up, adjustments to the home, habits around hydration, a conversation with a doctor about medicines — that can make a genuine difference. The goal is not to wrap someone in cotton wool. It is to help them stay on their feet, in their own home, on their own terms.

That goal is absolutely worth pursuing.
