The mHealth Grand Tour Team

From Barcelona to The Alps, Powered By Insulin

From the moment I sat down to dinner with my new team mates the night before the tour, I knew this was going to be an unforgettable experience. Across from me was Nenad, a type 1 athlete from Zagreb who had completed a triple ironman (which consists of a 11km swim, a 540km bike ride […]

Review: Best Tape For CGM Sensors

Keeping continuous glucose monitor (CGM) sensors stuck on properly can be something of a challenge. Showering, sweaty gym sessions, swimming and the general rough-and-tumble of daily life all conspire to help remove your costly CGM sensor from your body. But how best to keep them from working loose? Kinesio tape is a popular way of […]

New approaches to diabetes management through self-monitoring and Big Data

With the prevalence of mobile computing, self-monitoring and Big Data technologies, new approaches to the management of type 1 diabetes management might be possible. Take for example the administration of insulin in type 1 diabetes when eating pizza. It is often reported that rather than taking one single bolus insulin dose when eating pizza, the insulin […]

Effect of exercise on basal insulin rate in type 1 diabetes – experiment 1

1. Introduction In Type 1 diabetes, exercise has an effect on blood glucose levels. In general, during periods of low to moderate intensity exercise, blood glucose levels will drop. To counteract this, either insulin is reduced or carbohydrate intake is increased. Moreover, it is often reported that this effect may last for up to 24 […]

Analysing heart rate and diabetes data using R

At the start of the project I thought I would be spending all of my time using Hadoop and other Big Data technologies to analyse my data. The conclusion that I rapidly came to is that if you don’t have huge amounts of data then Hadoop is probably not the best option. Once I have a […]

Processing Diasend CGM and insulin data

As part of my project to correlate exercise and insulin usage in type 1 diabetes I need to get hold of my blood glucose and insulin usage data. I use an insulin pump with an embedded continuous glucose monitoring (CGM) sensor. Periodically I upload all the data from the pump to Diasend. Diasend is quite a […]

Accessing heart rate data from Strava API

In my last post I looked at options for recording heart rate data. I settled on using a Garmin HRM strap, linked to my Garmin Edge 500 and Garmin FR70. I use the Edge while on my bike on the road and in the gym (you can link the Edge to a Wattbike, which is […]

Quantifying exercise – continuous heart rate monitoring

One part of The Glucose Project is to try and quantify exercise so that it can be correlated with insulin usage and blood glucose level. The question I want to answer is, depending on the amount of exercise I have done, how should I adjust my insulin dose? My first approach is to look at heart […]

The Glucose Project – correlating exercise and insulin usage in type 1 diabetes

I’ve finally found it. I have been trying to think of a good project to get my teeth stuck into – something that will get me up to speed with all these new Big Data technologies as well as being of some use – and I think i’ve got one: The Glucose Project. In brief, […]
