Vanity



 https://youtu.be/vEqRC3pnJvE


Let's take a moment to appreciate this wonder. It is

now possible to see, in close to real time, one's glucose reading.

Different from a medical test from actual blood by 10%

at most. The technology to do this is from Dexcom, based in San Diego

California. 


The test mechanism, on the person's arm, sends the data to an app

on the iphone. An app on the Applewatch receives, and shows it.

It is a trend line. A tap on the watch and there it is.


Apple has been promising direct reading of glucose from the watch itself,

without invasive procedures. It is a much awaited feature, and the company has

apparently taken a patent on a technology to do this, already. I do see, however,

how there might be some apprehension about moving ahead with this:

fitness is one thing, and medical treatment another. Could this feature lead to frivolous 

uses, or endanger some patients. I would hope not.


In fact, I would see this as a very useful development. Take the pizza problem, as it

confronts someone with diabetes1. Pizza is a carbohydrate food, and requires an insulin

injection before ingestion. All fine and good. But then, hours later glucose readings go up

again, and who knows what is going on. Pizza also contains fat from the cheese.

I would expect that with many 'vanity' users using this feature, we woud soon

find out.


It takes a few hours for fats to leave the stomach for the small intestine. What happens 

next will depend on whether your body is trying to find quick energy, seeking to restore 

glycogen in muscle for easy access, or willing to send it to long-term storage. As someone

who goes out in sub-zero tempratures for a quick shop, I have some ingtuitive grasp

on how my diet helps or hinders my activities. I just know I could get really good at

gauging what is going with me as a function of diet and activity.
