Talk:Blood sugar

From Wikipedia, the free encyclopedia

This article needs information on how blood glucose levels are measured or a link to the same information. Regards.

The Afternoon Sleepies

I used to suffer from this big time. Around two or three in the afternoon,
I'd start to get drowsy and nothing I did could fix it. A lot of people
suffer from this, but don't know the reason.

The most likely cause is low blood sugar. A large lunch, especially with
lots of starchy foods, will cause your blood sugar to spike and then crash.

... I don't know how true this is ... I added a short piece about it, that information would be useful in this page. But I don't know how valid it is. Flammifer 08:10, 9 Jun 2005 (UTC)

Not at all :) People commonly attribute this to their lunch, but that's a fallacy of corrolation implying causation. Actually, people naturally have a dip in their circadian rhythm at that point, and it really has very little (if anything) to do with food. —The preceding unsigned comment was added by BennyD (talk • contribs) 15:22, 25 January 2007 (UTC).

It's not terribly consistent with the way insulin and glucagon work in nondiabetics who aren't insulin-resistant. There is indeed a spike of insulin immediately after a meal (actually during the meal, as blood sugar spikes), but a few factors ensure that this doesn't result in rebound hypoglycemia. The major one is that the quantity of insulin released is almost never enough to fully correct the postprandial spike in blood sugar-- that's why there is a second, slower release of insulin that comes longer after a meal, and which tapers off very gradually. Reactive hypoglycemia does seem to be a real phenomenon, but it is quite rare-- certainly nowhere near as common as mainstream diet literature would lead you to believe.-- Kajerm

[edit] Determination

Perhaps we should mention here the chemical determination of sugar levels. I found the classical reference for an early method (Somogyi, M. Determination of blood sugar. J. biol. Chem. 1945, 160, 69.) JFW | T@lk 22:57, 17 July 2006 (UTC)

[edit] Other Sugars in Blood

I think it would be a good idea to add some more on other sugars found in blood, and how thay are used. I'm not exactly sure what other sugars are in blood or the relative concentrations. Anyone know? User:tcopley 00:10, 4 April 2007 —The preceding unsigned comment was added by 210.4.228.192 (talk) 14:11, 3 April 2007 (UTC).

[edit] Diabetes and relation to eczema

Is there a relationship of diabetes to eczema? 209.221.206.240 15:44, 5 February 2007 (UTC)
