Type 2 diabetes

I'm not a medical professional and I don't take insulin so even though I have type II, this is won't be helpful. I would definitely speak with your doctor and even a dietician if you can. My dietician said to eat some protein and/or healthy fats before swimming and since I have been going during my lunch break, I usually eat a power crunch bar and drink some isopure fusion drink or have some nuts. Or I might have an apple and some all natural peanut butter. Then when I get home I eat lunch. I am just returning to the sport after a couple of decades away so I am not sure if it will get harder to manage my diabetes once I start practicing with a team again. My dietician said that I might have to have a snack during practice which I have never had to do before and don't even know how I would do that. As to your specific problem, I think it's strange because usually exercise lowers blood sugar so I wonder if your pancreas is creating more sugar to compensate, sort of like how it can get higher in the morning? Have you tried eating some protein before you swim? 

Thank you for your response. In my research I have found that the insulin storage process effectively stops during intense exercise. The fat gets pulled from the muscle and liver to be converted into ATP and burned off as energy. I am thinking this process doesn't immediately stop once exercise is done and the insulin hormone takes a bit to kick back in for storage duties. I've taken 10 units of insulin due to my BS being over 200 and an hour later I'm crashing. I have a consult in with a dietician with my VA. I've also started a membership with an athletic trainer for resistance training. He's an angry elf. lol From what I understand weight training is the best bang for your buck in managing diabetes. Because fat is initially stored in muscles and the liver weight training really focuses on getting that fat out as quickly as possible. This explains the wall I run into swimming. I am now in a 3 prong attack of swimming, weights and diet. Hope this helps someone else. I'll follow up after I talk to the dietician. Type2 doesn't have to be a death sentence. #GettinStrongerEveryday
