Hi, My husband is 33yrs old and he was found to be prediabetic 4 yrs ago. He does fasting glucose test at home every week and his levels are mostly in 100-120 range. Recently, he did a test 2 hrs after dinner and it came 109, but when he tested it the next morning it was 123! We are confused as to what is the issue here? is it common? He has been going through work stress lately and has been losing muscles and weight since past few months.
