Ottai Continuous Glucose Monitoring System

The Ottai CGM is used to provide a continuous measure of blood sugar levels over a 14 day period. It works a small painless disk attached to your underarm and through bluetooth connection relays blood glucose information to an app on my phone. It gives lots of detail but unfortunately I have found it to report lower levels of my blood glucose by 2 mmol/L when compared with a finger prick device. While this is a drawback the Ottai is quite consistently inaccurate. It is about half the price of the Libre 2 system as there are deals online selling it for around $54 Au. The good thing is I find it quite motivational in understanding how different foods impact on my blood glucose levels. For example I have almost cut out boiled rice as it really causes a sugar spike for me. I have also been able to find substitute foods that reduce blood sugar spikes. It also helps with weight management and impacts of exercise.

Overall the Ottai is a useful tool to monitor my diet and because it is still quite expensive I only use it to help bring my wayward eating habits under control.

Give it a go. The knowledge you gain could change your life.
