What to do if…
you faint briefly and wake up feeling confused about what happened

Short answer

Lie down and stay still until you feel fully steady (often several minutes), and get someone to help you check for red flags. If you don’t wake within about 1 minute, don’t fully recover, or you have chest pain, palpitations, serious injury, trouble speaking/moving, or anything seizure-like, call 999.

Do not do these things

  • Don’t “push through it” or stand up quickly to test yourself.
  • Don’t drive, cycle, or operate anything risky afterward.
  • Don’t take extra doses of medicines (or stop prescribed medicines) to “fix it” without clinical advice.
  • Don’t drink alcohol or use recreational drugs to “calm down”.
  • Don’t stay alone if you’re still confused, injured, or unsure why it happened.

What to do now

  1. Get into a safe position and stay there. Lie flat if you can. If you feel faint again, keep lying down and raise your legs (on a chair/sofa cushion). Loosen tight clothing and get fresh air.
  2. Do a quick safety check (30–60 seconds).
    • Are you breathing normally?
    • Did you hit your head or have significant bleeding?
    • Can you speak clearly and move both arms/legs normally?
      If anything is not right, treat it as urgent.
  3. Call 999 immediately if any of these apply (now or during recovery):
    • You cannot be woken within about 1 minute, or you’re not fully recovering.
    • Difficulty with speech or movement, new one-sided weakness/numbness, facial droop, or severe unsteadiness.
    • Chest pain or a pounding/fluttering/irregular heartbeat (palpitations), or significant shortness of breath.
    • A serious injury (especially head injury) or heavy bleeding.
    • Shaking/jerking like a seizure/fit.
    • You fainted while exercising or while lying down.
  4. If you’re not calling 999, get same-day advice if it was unexplained, you woke up confused, or it’s your first episode.
    • Ask someone to stay with you and call NHS 111 (or ask them to call for you).
    • If confusion persists or worsens, you have a significant head injury, severe headache, repeated vomiting, or you’re not getting back to normal: go to A&E or call 999.
  5. Make it safer while you’re recovering.
    • Sit/lie somewhere you can’t fall again (not in a bath/shower).
    • Keep a phone nearby; if you’re alone, unlock your door and ask someone to check in within the next hour.
  6. Write down what you can while it’s fresh (for NHS 111/your GP/A&E).
    • When it happened, what you were doing (standing up fast, pain, heat, toilet, exercise), and roughly how long you think you were out.
    • Any warning signs (sweating, nausea, tunnel vision) and what you feel now (confusion, headache, palpitations).
    • Any witness account (did you go pale and slump, did you shake/jerk, were you hard to wake, was confusion prolonged).
  7. If you have diabetes or suspect low blood sugar: check your blood glucose if you can and follow your usual hypo plan. If you can’t safely eat/drink or confusion continues, get urgent help.

What can wait

  • You do not need to figure out the exact cause right now.
  • You do not need to decide today whether it was “just a faint” versus something else—focus on safe monitoring and getting assessed.
  • Returning to driving, exercise, alcohol, or risky tasks can wait until you’re clearly back to normal and you’ve had medical advice (especially if it was unexplained).

Important reassurance

Feeling shaken, embarrassed, or confused after fainting is common. The goal right now is simple: prevent another fall and make sure warning signs that need urgent care aren’t missed.

Scope note

These are first steps for the next minutes and hours. Follow-up tests, diagnosis, and prevention are separate decisions best made with a clinician once you’re safe.

Important note

This is general information, not a diagnosis. If you’re unsure, worsening, alone, injured, or not quickly returning to normal, treat it as urgent and use NHS 111/999 as appropriate.
