How long after meals before testing

Hi Fiona,

For most people a test at 1 hour after eating should show your BS at around its highest level and at 2 hours it should have returned to pretty close to the pre-meal level (its not an exact science but those times are close enough). But in your case those figures may not be true because Byetta slows down the rate at which food passes through the digestive system, which in turn slows down the rate at which it gets converted to glucose. You may find that your own peak comes more than an hour after eating and that the return to normal takes longer than 2 hours. Or alternatively that the levels remain high for longer than usual before they start to drop. If you want to experiment then I would be very interested to hear the results.

Your question about the coke in a non-diabetic person - although coke will raise BS very quickly, the reaction of insulin is the same whether the carbs consumed were converted to glucose quickly or slowly. The insulin would be produced quickly but would still take up to 2 hours to metabolise the sugar.
