I treat with
zinc, which keeps my copper levels low (but
zinc causes nausea - but its better than the consequnces).
At any rate, Wilson's is a treatable and manageable condition. IF detected early enough and if the variant is a slow progressing one, then your Sis could go on to live a full healthy life with med management. - So, I guess what im saying is that in some circumstances, Wilsons isnt the worst you could ask for.....
