Short answer

Lie down flat and raise your legs, or sit and put your head down until the feeling passes. Call 999 if you faint and are not breathing, cannot be woken within 1 minute, are not fully recovered, have difficulty with speech or movement, have chest pain or a pounding, fluttering, or irregular heartbeat, have a seizure or fit, are seriously injured, or fainted while exercising or lying down. Because the symptoms keep returning, get same-day urgent medical advice even if you feel better between episodes.

Do not do these things

Do not try to push through it, especially on stairs, during exercise, in a hot shower or bath, or while standing in a queue.
Do not stand up quickly or walk around to test whether it has gone.
Do not drive, cycle, use ladders, or use tools until you are reliably steady and have had advice if episodes keep returning.
Do not drink alcohol or take sedating drugs right now.
Do not take extra doses of any medicine, including blood pressure tablets, to try to fix the feeling.
Do not stop prescribed medicines suddenly unless a clinician tells you to.
Do not stay alone if you are repeatedly going faint, especially on stairs or in the bathroom.

What to do now

Get into a safer position immediately.
Lie flat and raise your legs on a chair, sofa cushion, or pillow. If you cannot lie down, sit and bend forward with your head down and your feet flat. Loosen anything tight around your neck or waist, and keep the room cool.
Protect yourself from choking if you feel sick.
If you are lying down and feel as if you might vomit, roll onto your side.
Do a quick emergency check.
Call 999 if you or someone with you faints and they are not breathing, cannot be woken within 1 minute, have not fully recovered, have trouble with speech or movement, have chest pain, have a pounding, fluttering, or irregular heartbeat, have a seizure or fit, are seriously injured, or fainted while exercising or lying down. Also call 999 if breathing is severely difficult, you are gasping or choking, or you cannot get words out.
Get someone to stay with you, or stay on the phone.
If you are alone, send a short message such as: “I keep going faint. Can you stay on the phone with me?” Keep your phone within reach.
Stop the pattern that is making it come back.
Avoid standing for now. When you need to move, do it in stages: lying down, then sitting, then standing. If the faint feeling returns, stop and sit or lie down again straight away.
If it is safe for you, take a small drink and a small snack.
Sip water or an oral rehydration drink if you have one. A small snack may help if you have not eaten. A salty snack may help some people after sweating, vomiting, diarrhoea, or poor fluid intake, but do not do this if you have been told to restrict salt or fluids. If you have diabetes or suspect low blood sugar, follow your usual plan and check your glucose if you can.
Make a short note for medical advice.
Write down when each episode happened, what you were doing, whether standing, heat, a shower, missed food, illness, or dehydration seemed involved, and whether you had palpitations, chest pain, breathlessness, heavy bleeding, vomiting, diarrhoea, or a recent medicine change.
Because it keeps returning, get same-day urgent medical advice.
Use the urgent-care route for where you are: NHS 111 online or phone 111 in England, NHS 24 on 111 in Scotland, NHS 111 Wales in Wales, or the relevant GP out-of-hours or Phone First route in Northern Ireland. If symptoms are persistent or worsening, ask for urgent advice now rather than waiting. Go to A&E or call 999 if you are told to, if you have collapsed or been injured and cannot stay safe, or if any emergency warning sign is present.
If you are pregnant, get urgent pregnancy-specific advice as well.
Contact your maternity unit, midwife, or local urgent-care route. If you collapse, have chest pain, severe breathlessness, heavy bleeding, severe abdominal pain, or feel in immediate danger, call 999.

What can wait

You do not need to work out the exact cause during the episode.
You do not need to decide now about tests, referrals, long-term treatment, exercise plans, diet changes, or wearable data.
You can leave detailed tracking until after you are safely assessed.

Important reassurance

This can feel frightening, especially when it keeps coming back. The most protective first step is simple: get flat or get your head down, reduce the chance of a fall, and do not test yourself upright too soon. Getting same-day advice for repeated near-fainting is a sensible safety step, even if you feel okay between episodes.

Scope note

These are first steps to reduce the chance of injury and avoid missing urgent causes of faintness. Once you are stable, a clinician may suggest checks such as blood pressure including standing blood pressure, an ECG, blood tests, or a medication review.

Important note

This is general information, not medical advice, a diagnosis, or a substitute for professional care. If you think you are in immediate danger, call 999. If you are unsure whether it is urgent, use your local NHS urgent-care route for advice.
