Recently my blood sugar levels just before bed have risen to almost double the daily numbers. This does not seem to depend on what I eat. Could there be another reason? I am type 2 and have been for many years.
If your eating or exercise habits are the same as they have been, you may need to change or increase your oral medication or start insulin. The best way to know if you need more medication is to check your blood glucose before and 2 hours after one meal each day. You can vary which meal this is. Eat a reasonable amount of carb for that meal -- aim for 60 grams. Check your blood glucose before and after the meal, write down the numbers. If your post-meal blood glucose is 50 points higher than your pre-meal number on several occasions, then you will want to talk with your healthcare provider about medication options. Try not to be too discouraged about the numbers, it is very common for blood glucose numbers to go up over time and for more medications to be needed.
