Hi, I'm sort of slipping into doing paleo due to health problems but do have the odd treat, especially popcorn. My question is: does the blood get sticky when we have a sugar spike after a high GI load food?
The reason for asking is that I have venous reflux in my leg due to an old DVT and when I eat a big tub of popcorn the vein is more painful than usual for a couple of hours afterwards. I have now experimented for a few days with strict adherence to no sugar of any sort. I'm also having complex carbs and low GI foods and the vein symptoms are better than they have been for months. Practically no pain. If I knew there was a link it would keep me focussed on keeping strict about it.
Extra info: I'm not diabetic- I was tested recently. I realise that if the blood does get sticky it wouldn't affect ordinary people so much- it's just that with me it's fighting its way thru a damaged vein. Also, I don't need advice on DVT, it's the sugar/blood coagulation thing that I'm intrigued about. I know popcorn is mostly starch but it has quite a high GI index (60-80)and I have 100 grammes at a time.
I did do some googling on this. There was one result that mentioned excess glucose dehydrated the blood leading to greater stickiness; another said it coats the platelets like sugar glazing! That would be interesting. Both sources didn't look too reliable though.

The idea that hyperglycemia increases coagulation seems pretty well supported:
Does this mean a hefty glucose spike in a non-diabetic person eating high GI carbs is going to increase coagulation? It may actually. In that last paper the researchers used non diabetic subjects as a control group and measured levels of "Prothrombin fragment 1 + 2 (F1+2), which represents a reliable marker of the amount of thrombin released in the circulation". After an oral glucose tolerance test (which often means eating about 75 grams of glucose) "F1+2 significantly increased in both diabetic and healthy subjects".
Perhaps this is why your leg feels painful? I don't know much about DVT myself, so I'll just leave this information here.
