Hi, My sister is 70 years old, a few months back she tested high for glucose and the doc asked her to come back for a full lab work. My sister did not go back, it s been months. She just did her own treatment, went on a crash diet, lost 20 pounds. Her tests are still high but she does not want to go back for a complete lab work because she just wants to stay on diet and not take meds. What are the risks she s facing? ana
