My 87 year old mother has just been admitted to hospital with low sodium levels (this was only found out after blood tests at the hospital). Last week she kept falling and wouldn't settle at all. After 3 days the Nursing Home called a Doctor out and he thought she had a urine infection. I went to see her at the Care Home on Tuesday and she seemed delirious to me and very agitated, so insisted they called an ambulance. I'm glad I did because the Doctor at the Hospital said it can be very dangerous if left untreated. Has anyone else heard of this condition in the elderly. I was also wondering if this could happen again.
