Fasting for 12 hours

10:00 AM 185 mg/dl

1:00 PM 195 mg/dl > rise of 10 mg/dl

2:00 PM 193 mg/dl > fall of 2 mg/dl

3:00 PM 153 mg/dl > fall of 50 mg/dl

4:00 PM 164 mg/dl > rise of 11 mg/dl

5:00 PM 136 mg/dl > fall of 27 mg/dl

6:00 PM 153 mg/dl > rise of 17 mg/dl

7:00 PM 138 mg/dl > fall of 15 mg/dl

8:00 PM 137 mg/dl > fall of 1 mg/dl

9:00 PM 119 mg/dl > fall of 18 mg/dl

10:00 PM 115 mg/dl > fall of 3 mg/dl

Average BG: 153.45 mg/dl

Please note on this topic that I didn't so much as eat a nibble of anything.

THAT was a challenge.

so my body can take care of its sugar so long as nothing else is put into it for 12 hours.

eh is this good?

Or is this bad? *like I am suspecting it is*

It's pretty self explanatory. Your BG dropped substantially during the test, so this would suggest that you should lower your dosage and try again. How much... well you have to make an educate guess. I think you said you take 40units, a rough idea might be to reduce by 2 to 4 units and try again.

By the way, did you wait 4 hours after a meal/bolus before starting the test?

BG meters are not 100% accurate so doing an average BG out to 2 decimal places is fairly meaningless math.

What do you think about your average being over 150 mg/dl over a 12 hours fast..? What do you think a normal BG level should be..?

Good questions, but in this case the actual number isn't really that relevant (within reason), as the function of long acting is not to change your BG level but keep things as stable as possible.

This was a test without insulin usage and without a 24 hour basal dose of lantus.

I hadn't eaten anything all day so I didn't take humalog.

I wanted to see how my body reacted to the sugars already in its body and also to see if my body still creates insulin for its needs even though my capacity for creating insulin has been substantially reduced

This was after everything in my body wore off.

So this is my body doing its own thing.

I did the figuring myself so I only post to my average bg level what I do with a calculator.

But I see what you are saying.

and about the 150 mg/dl + rating, no I don't like it at all I wish it would be normal for God's sake but I can't seem to do it.

My resting rate used to be 196 so I dunno what this means.

It can take quite a bit longer than 24 hours for all lantus to exit the system.

From the results of this rather dubious test, you are deducing that you have no basal requirements at all. Considering you normally take 40 units lantus daily and seem to be running high most of the day in the ordinary course of things, I find this extremely hard to believe. It is within realms of possibility that you take far too much basal and far too little bolus, thus the food is somehow propping you up on what is an insane amount of Lantus if indeed you need no basal.

I don't know. From your posts I have to observe you seem to complicate things rather than just do some simple procedures and answer some simple questions. If I were you I would focus on testing and correcting obviously ineffective insulin doses, both basal and bolus, rather than spend effort and time in flawed experiments trying to prove I don't need basal insulin.

A poll with only those two options? "Fasting" without stating for how long, using what method, and the intelligence or ability of the person fasting, is pretty much open book. And fasting to what aim?

[Olidus]

Also - someone correct me if I'm wrong but the human body will store glucose on a "reserve" to be used if and when needed no?

I'm not sure what the fasting is for, but I sometimes fast for my own personal reasons. It is not always a complete fast, but whenever you drastically change your diet (even for a small amount of time) you should be careful to know what your blood sugar levels are. As for your test, I think I came in on the tail end of a conversation, so I'm going to leave that alone.

The test, so to speak, was to evaluate how my body would handle itself in the absence of insulin. The fasting was to ensure that no other glucose sources entered my body and screwed around with that test.

I wanted to see the severity of my diabetes at this time really I suspect that my endo would be able to tell me better what it means.

OK... as above I think that you are over-complicating things. For example... what does a 12 hour fast tell you about how your BG behaves on a "normal" day? Also as stated above you would likely need a few days without insulin to be sure that there is none left active in your system... even the shortest acting has been found still active a day or so after injection. But fasting for too long without insulin, is risky if you are a Type 1.

You need to try and establish a normal day and work the carbohydrate, insulin and BG numbers around that. You will find that the management of Diabetes is less of an exact science and more of an art... you can do the same things (food, exercise, insulin etc...) two days in a row and get different BG readings. So you need to test your BG spike after meals and be prepared to adjust the carbs and insulin to improve your BG levels. Read about basal testing.

Hi All

Two days a week, for weight reasons I fast, usually from a Sunday night through to a Wednesday evening I continue to take Levemir as normal in the evening and monitor BG every few hours and take Novorapid as required.

With out fail, BG levels rise through out the day and small doses of insulin are required every five hours of so.

Together with exercise this regime helps me keep to my desire weight as well as have a few calorie treats on a weekend all with no adverse affects.

[lorilei]

Wow, Neme...that sounds like torture!

[fgummett]

Surely fasting is counter-productive for weight loss... the metabolism slows so that the body burns less energy even at rest and when [generic] you do eat you might tend to be hungrier and more likely to put back on extra weight.

With respect, I read that starving and then overfeeding is a method used to fatten animals.

I also read that our bodies can store enough Glycogen in the Liver and Muscles for 24 - 48 hours... perhaps this explains the raise in BG even when fasting
