UPDATE (3/13) - Thank you for the prayers! My sister and I spent the evening in the ER with my Mother. Her potassium levels were elevated, which can signal renal failure. But, she felt well and her EKG was fine. The doctor gave her an IV and medication to bring her potassium down. Fortunately, she was not admitted and we were able to go home late last night. My Mother was ready to go!
The ER physician noted her kidneys did show signs of wear and tear. But, at 79 years old, that is to be expected. We'll be following up with my Mother's primary care physician in the coming days to determine if she should be referred to a kidney specialist. I'm trying not to let worry overtake my thoughts. But, my concern is my Mother may be on the path towards dialysis.
