Is there such a thing as too much BG testing? I was told by my Dr that I was testing too much & that it was detrimental to my health. I test 7-8 times/day. I take 2 types of insulin injections, equating to 4 shots per day. My nurse asked me to test at wake-up, before and after each meal, bedtime, and if I get up in the night. Mixed messages are confusing me. Wondering if you have encountered the "too much" issue prior, and what you think?

The recommended schedule for checking blood glucose levels depends on the type of medication you take. You are on two types of insulin, so at a minimum you should be checking your blood glucose before meals and at bedtime (as your nurse advised). We recommend additional checks if you suspect your blood glucose level is low, if you are exercising, or if you are trying to fine-tune your mealtime insulin doses. Checking routinely 7 to 8 times per day is usually not necessary, as that can cause an increase in anxiety, and it doesn’t necessarily help improve control. If your A1C is less than 7 %, do not worry about getting the daily blood glucose levels “perfect.” Also, checking too much can cause some people to take too many correction doses of insulin too close together, increasing the chance of low blood glucose reactions. Try to when you think there is reason to. Are you feeling low? Are you afraid of lows? Are you afraid of going high? Talk to your educator about your numbers.
