Flash glucose monitoring measures glucose levels using a sensor that is placed under your skin. It records your glucose levels in the interstitial fluid under your skin every 15 minutes.
You can find out your glucose levels by scanning the sensor, without having to prick your fingers.
Are you new to FGM? Here are some tips on how to make the most of it.
1. Scan your glucose levels throughout the day, and at least once every 8 hours
This will help you to see patterns and understand what needs to be changed to achieve better glucose levels.
Here are suggested timings to perform a scan:
Your glucose levels result on FGM and a finger-prick test may differ, especially when your glucose level is rising or falling. If your symptoms do not match your FGM glucose level, please take a finger-prick test to confirm.
2. Know your Blood Glucose Targets
Discuss with your targets with your healthcare team. The goal is to keep your glucose levels within the target range as much as possible.
An example of glucose targets:Before a meal2 hours after a meal4-7 mmol/LLess then 10 mmol/L
An example of glucose targets:
If your glucose level is out of your target range, you can modify your food intake or physical activity. You may also need to have your diabetes medications adjusted. Discuss with your healthcare team.
3. Use the trend arrows
The trend arrows help you understand how your glucose levels are changing.
4. Keep a Diary
To turn the glucose readings into useful information, record your food,
exercise and diabetes medications as well. Include remarks such as whether you
were feeling unwell or experiencing any hypoglycemia symptoms.
You can record your diary using the glucose senor app, sensor reader, or using a manual log-sheet.
Sharing your record with your healthcare team will enable them to help you more efficiently.
1. Time in Range (TIR)
Time in Range is the percentage of time your glucose is within the target glucose range. By setting a target TIR with your healthcare team, it gives you an objective goal to work towards.
Here's an example of someone who's target glucose range is 4-10mmol/L. His/her goal is to spend more than 70% of time within the target range, and less then 5% of time below 4 mmol/L.
Aim to improve Time In Range by 5% at a time.
2. Daily Patterns
The daily pattern graph shows how your glucose changes throughout the day. Look out for specific times of the day when you are prone to low and high glucose levels. Look out also for times when glucose levels are within range.
