My mom is 73 years old. About a month ago, she went to the doctor for her regular six month check-up, and received the results of her blood tests. Her doctor informed her that her blood sugar was elevated, and that she should change her diet. My mom has never had high blood sugar before, but did drink about 2-3 Pepsi's per day for the past 45 years. She switched to diet Pepsi, and has cut back to 1 soda per day. Today, when we were at the store, she all of a sudden turned extremely pale, got dizzy and weak, and said she felt like she was going to pass out. She is on medication for high blood pressure and one for cholesterol, which is hereditary in her family. The doctor had said that she should come back in 3-6 months in order to have more blood work done, but I am concerned that perhaps this is turning into diabetes. I am seeking advice as to what I shoul direct my mother to do. Thank you.
