Diabetes is a condition that is really tricky. There are a lot of considerations that you have to take note of. Blood sugar levels become erratic when you have diabetes. This may be caused by the insulin-glucagon balance, stress, diet, exercise, lifestyle, and even the time you take your medication. But hard as it is to admit, there are times when your blood sugar levels go crazy all of a sudden. This unexpected irregularity to your blood sugar may even occur even if you know very well that you stick to your routines everyday. When this happens and you are on long acting insulin, maybe it is time to check it s adjustment already.
