- If you have frequent hypoglycemia (low blood sugar).
- If you find difficulty in controlling the recommended levels of your A1C results.
- If the blood sugar level fluctuates frequently.
- If you’re mostly unaware on your blood glucose level.
- If you’re trying to reduce A1C levels safely with lower risk of having hypoglycemia.
One thing to understand about CGM units, mostly they work on the interstitial fluid! So they don’t check your blood directly.
Glucose (sugar) shows up in the bloodstream first– as the name suggests ‘blood sugar’. It moves and spreads around the body via blood. And this process takes time to deliver glucose into the tissues and organs.
Also, the level of glucose may vary in different body parts. For instance, you could have 120 mg /dL of blood sugar level at your toe – while at the same time the level could be 100 mg /dL at your fingertip.
Instead, focus on the arrow indicators (trend) of your blood sugar level – whether it’s stable or not. The trend is way more important in controlling your diabetes than the exact number showing on the screen.
Since CGM units check glucose level on interstitial fluid, there is a lag time. So comparing the fingerstick result to what you get with CGM is an inappropriate step, because there’s always a chance to see a difference on the screen.
In addition, today there are lots of glucose meter units on the market. All these products have different accuracy rates (about 5-20 percent if compared to gold standard venous blood). For more guidance, see your specialist or healthcare provider!
