These concerns usually need timely assessment but are not always emergencies.
Seek urgent or emergency help for:
Confusion, fainting, a seizure or inability to wake, especially with possible low blood sugar
Severe weakness or dizziness with ongoing watery diarrhea
Vomiting blood, black stools or sudden severe abdominal pain
Signs of severe dehydration, such as very little urine or marked drowsiness
Fever with jaundice or severe abdominal pain
New chest pain, severe breathlessness or stroke-like symptoms
If low blood sugar is suspected and the person is awake and able to swallow safely, follow their established emergency plan.
Do not give food or drink to someone who is unconscious or having a seizure.
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

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you have persistent or recurring symptoms such as unexplained abdominal pain, weight loss, repeated diarrhea, frequent ulcers, a new unusual rash or episodes that may represent low blood sugar.
And for anyone, someone who:
has noticed a lump, a mole that has changed, or unexplained weight loss
Every sign above is quoted from the sofidex article on Islet cell cancer. If you are not sure, err upward — it is always reasonable to be checked.
