Warning-sign checks

Hyperkalemic periodic paralysis: 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 medical help if weakness:

    • Affects breathing, swallowing, or the ability to hold up the head
    • Occurs with chest pain, a racing or irregular heartbeat, or fainting
    • Is severe enough to prevent safe movement
    • Affects one side of the body or occurs with facial drooping or speech difficulty
    • Comes with confusion, loss of consciousness, or a serious injury

    And for anyone, someone who:

    • is bleeding heavily and it will not stop with firm pressure
    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 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

    A laboratory result showing significantly elevated potassium also needs prompt medical assessment, even if symptoms seem mild.

    High potassium can have causes other than periodic paralysis and may affect the heart without obvious warning symptoms.

  3. 3

    Does any of this apply?

    Book an appointment

    Arrange routine medical follow-up if attacks are becoming more frequent, lasting longer, or changing in character.

    Also seek review for new weakness between attacks, repeated falls, medication side effects, or difficulty managing triggers.

The article also says

A first unexplained episode of paralysis needs medical assessment.

Several conditions can cause sudden weakness, and the correct treatment depends on the cause.

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