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

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Lie down or stay seated, keep yourself from falling again, and ask someone nearby to stay with you while you check for urgent warning signs. Call 999 now if you are not fully recovering, you cannot be woken within about 1 minute, you are not breathing normally, or you have chest pain, palpitations, serious injury, trouble speaking or moving, seizure-like shaking, or fainted during exercise or while lying down.

Do not do these things

  • Do not stand up quickly to test whether you are fine.
  • Do not drive, cycle, use machinery, climb, bathe, shower, or cook over heat while you feel confused, weak, dizzy, or unsure what happened.
  • Do not stay alone if you are still confused, injured, or worried it could happen again.
  • Do not take extra doses of medicine, skip prescribed medicine, or stop prescribed medicine to “fix it” unless a clinician tells you to.
  • Do not drink alcohol or use recreational drugs to calm down.
  • Do not ignore a head injury, even if you woke up and can talk.

What to do now

  1. Make the next fall less likely. Lie flat if you can. If you feel faint again, keep lying down and raise your legs on a cushion, chair, or sofa. Loosen tight clothing and get fresh air.

  2. Ask someone to stay with you and check the basics. Ask them to confirm whether you are breathing normally, whether you hit your head, whether you are bleeding, and whether your speech, face, arms, and legs seem normal.

  3. Call 999 now if any urgent warning sign is present. Call if you:

    • are not breathing normally
    • cannot be woken within about 1 minute
    • have not fully recovered or remain very confused
    • have difficulty speaking, understanding, walking, moving an arm or leg, or have new one-sided weakness, numbness, facial droop, or severe unsteadiness
    • have chest pain, severe breathlessness, or a pounding, fluttering, or irregular heartbeat
    • have seriously hurt yourself, especially with a head injury or heavy bleeding
    • had shaking or jerking like a seizure or fit
    • fainted while exercising
    • fainted while lying down

  4. If you hit your head, take it seriously. If you were knocked out and then woke up, vomited, have a headache that does not go away, have memory problems, have taken alcohol or drugs, take blood-thinning medicine, or cannot get to A&E safely, get urgent help through 999, A&E, or NHS 111 depending on how severe it is. Do not drive yourself to A&E.

  5. If none of the 999 signs are present, get medical advice today because you woke confused. Call NHS 111, use 111 online, or ask someone to contact your GP or an urgent care service for you. Say clearly: “I fainted or blacked out, woke up confused, and I am not sure what happened.”

  6. Write down what happened while it is fresh. Note the time, where you were, whether you were standing, sitting, lying down, exercising, hot, in pain, on the toilet, hungry, dehydrated, or had just stood up. Ask any witness whether you went pale, slumped, shook or jerked, were hard to wake, or stayed confused.

  7. If you have diabetes or suspect low blood sugar, follow your usual hypo plan if you can do so safely. Check your blood glucose if you can. Do not eat or drink if you are too confused to swallow safely. Get urgent help if you are not responding normally, become unconscious, cannot safely treat the hypo, or confusion continues.

  8. Do not drive for now. If this was unexplained, happened more than once, happened while driving, or a clinician refers you for assessment, ask a doctor whether it affects your driving and check whether you need to tell DVLA.

What can wait

  • You do not need to work out the exact cause right now.
  • You do not need to decide whether it was “just a faint”, a seizure, low blood sugar, a heart rhythm problem, or something else.
  • You do not need to return to work, exercise, driving, alcohol, bathing alone, or risky tasks until you are clearly back to normal and have had appropriate medical advice.
  • You do not need to give a perfect account of what happened; a rough timeline and any witness details are enough for now.

Important reassurance

Feeling frightened, embarrassed, shaky, or foggy after fainting can happen. The immediate aim is not to solve everything; it is to prevent another fall, notice warning signs, and get the right level of help.

Scope note

These are first steps for the next minutes and hours only. Tests, diagnosis, driving decisions, medication changes, and prevention plans may need help from NHS 111, a GP, A&E, a specialist, or another appropriate clinician.

Important note

This is general information, not medical advice, diagnosis, treatment, or a substitute for professional care. If you are unsure, worsening, injured, alone, or not returning to normal, treat it as urgent and use 999, A&E, or NHS 111 as appropriate.
