My husband has just had his blood test done to check cholesterol levels etc as he has high blood pressure, all of the results were fine except for his blood glucose level that was 48, he now has to have a further blood test at the hospital to see how his glucose level has been in the previous three months and then another blood test in three months to check again. Is 48 very high and what will happen after the blood tests, will he be able to keep the glucose levels in check with diet alone, he is very active runs and isn't overweight. I am worried, can any one put my mind at rest. Thanks
