Diabetes is a wierd disease. It may present differently with all of us. I was super healthy before diabetes. I was a vegetarian, worked out at least 2 hours every day, was a normal weight and didn't eat any sugar or fat. My doctor was shocked too. Actually my eye doctor is the one who suspected diabetes when they picked up some small specks in the back of my eyes. When they sent me to a specialist to do a dye test they could see microscoptic tears. The Opthamologist knew immediately I probably had diabetes. Also our bodies get used to the higher bgs. Actually when we begin to lower them to the 70-120 range many of us feel ill and the body will rebell sometimes. The relationship of carbs to diabetes is basically how healthy your endocrine system is. When everything works perfect you eat carbs and your pancreas immediately pushes out insulin to push the glucose from the carbs into our cells to be used as energy. The problem comes when our pancreas no longer pumps out enough insulin or the insulin we do produce is not recognised by our cells and the glucose cannot enter the cells. This is called Insulin Resistance. Some drugs like Januvia and Metformin help us become more sensitive to our own insulin. But it sounds like they aren't working in your case. It does seem you are eating more carbs than your pancreas can handle. Many of us have to cut back on the carbs. I have had to cut back to 10-15 carbs per meal. I cannot eat anything made with wheat flour because it spikes me for hours. So I have cut out all breakfast cereals, breads, muffins, pancakes, chips, etc. Every once in awhile I do a test to see if I can add them back in. I usually fail it every time. I love chips and bread but I will spike to 200+ if I eat them. Luckily a lot of my online friends are great chefs and we have figured out ways to make our own LC breads, cookies, muffins, pancakes, biscuits and even fudge. With bgs as high as yours your doctor needs to take agressive action. Make sure you ask for a C peptide and GAD test , so you know what type of diabetes you are dealing with. I would also ask for insulin to get your bgs back into a normal range. Once you get bgs stabalized you could cut back on the insulin and maybe add back the oral drugs. But changing diet is imperative. Eating a higher carb diet will only make your bgs go higher especially if you are not injecting insulin. But the bigger issue here, is the complications that come with any bg over 140. I know you feel fine now, but damage is going on inside your blood vessels that may lead to serious complications 5-10 years down the road. My dad was dx'd a few years ago in his late 80's. His dietician suggested a high carb diet, he now has severe neuropathy and can barely walk.
