Warning-sign checks

E coli enteritis: when to get help

Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.

  1. 1

    Is any of this happening now?

    Call 911

    Seek emergency care for signs of HUS or severe illness, such as no urine, unexplained bruising, marked paleness, swelling, confusion, collapse, or difficulty waking.

    Call your local emergency number if someone is unconscious, has trouble breathing, or appears severely dehydrated.

    Other emergency signs, for anyone
    • Someone who is struggling to breathe, gasping, choking, or cannot get words out
    • Someone who has chest pain, tightness or pressure lasting more than a few minutes
    • Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
    • Someone who is unconscious, or cannot be woken
    • Someone who is bleeding heavily and it will not stop with firm pressure
    • Someone who has had a seizure that will not stop, or does not wake up afterwards
    • Someone who has lips or skin that look pale, blue, grey or blotchy
    • Someone who you believe has taken an overdose or swallowed something poisonous
  2. 2

    Is any of this happening?

    Be seen today

    Seek prompt medical advice if you have bloody diarrhea, severe or worsening stomach pain, repeated vomiting, or diarrhea that is not improving.

    Earlier assessment is also sensible for a baby, an older adult, a pregnant person, or someone with a weakened immune system.

    Get urgent same-day help for signs of dehydration, including:

    • Very little urine or fewer wet diapers
    • Persistent dizziness, marked weakness, or unusual sleepiness
    • A very dry mouth or inability to keep fluids down
    • A fast heartbeat or worsening confusion
  3. 3

    Does any of this apply?

    Book an appointment

    Routine follow-up may be needed if symptoms continue after the infection, if a public health team requests repeat testing, or if kidney function was affected.

    Return-to-work or childcare requirements should be handled through the relevant local service rather than assumed from symptom improvement alone.

Every sign above is quoted from the sofidex article on E coli enteritis. If you are not sure, err upward — it is always reasonable to be checked.
