Is any of this happening?
Be seen today
If Fanconi syndrome has been diagnosed, contact the usual care team promptly for vomiting, diarrhoea, reduced drinking, or a clear increase in urination.
These can disturb fluid and mineral levels and may require earlier testing.
Seek urgent medical help for:
Severe weakness, worsening drowsiness, or confusion
Fainting or inability to stand because of dizziness
A fast, irregular, or pounding heartbeat
Very little urine, despite being unwell or dehydrated
Inability to keep fluids or prescribed replacement treatment down
A suspected fracture or sudden severe bone pain

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you or your child has persistent excessive thirst or urination, unexplained muscle weakness, bone pain, poor growth, or repeated abnormal urine results.
These symptoms have many possible causes and do not establish Fanconi syndrome by themselves.
Every sign above is quoted from the sofidex article on Fanconi syndrome. If you are not sure, err upward — it is always reasonable to be checked.
