My mother-in-law’s nickname used to be the Diet Coke Queen. She now has osteoporosis. I don’t think it is a coincidence. She stopped drinking soda about two years ago and her problems have not increased like they had been doing every year. Make sure your mom gets a bone scan.
From liver problems to bone problems to diabetes, her soda consumption is definitely taking a toll on her body but she won't listen to anyone. She's set in her ways.
