here is a question if anyone can shed light based on their personal experiences. I was diagnosed with T2 about 18 months ago at a1c of 78 mmol. At the time of diagnosis i had several symptoms of diabetic complications including PAD, neuropathy, tingling in hands, high BP etc. When i normalised my BG in the next three months, all the symptoms were gone and even my eye exam came back clear. Fast forward a year, i maintained my BG in healthy range 5-7 mmol. Last three months, i tried to up my carbs a bit and did some experiments on different carbs and my BG control for couple of month was not as good as it used to be, spiking to 8 and 9 postprandial and a bit elevated fasting. within just 2 months of a little higher BG, i realised most of the symptoms started returning, BP went up, tingling started, felt some symptoms of neuropathy and my fasting glucose went up, indicative of insulin resistance. Had an eye exam and they found background retinopathy too. Just surprised, with just a little overdoing carbs and just for couple of months, all the hard work of a year goes away? Do you see the same symptoms returning back as soon as your BGs are not in range? I know we all are different, but i know many diabetics in family who have their BGs much higher than i had for the last two months for years and they don't have any of those complications. Can anyone explain this for peace of mind please? PS: Why would my eye exam be clear after years of high sugar and just having higher BG for couple of months after normalising it, i have background retinopathy? doesn't make sense for me and then i saw some post that say that when they were diagnosed T2 they didnt have retinopathy and after a year of control and diet, next year they found retinopathy, quite not understand that!
