Has anyone ever had or know anyone who has been admitted to hospital after high potassium levels? MIL currently at a and e and been there hours - we’ve offered to go up and let FIL come home as he is in poor health but they say no. What can we expect? Google suggests she may get put on IV treatment but she’s had nothing in 8 hours bar a blood test and ECG. she’s prone to pushing for treatment for everything- however small- so we struggle to know how serious this is but I want to help. Anyone?
