O.k so normally when I exercise it makes my blood sugar drop a lot. This morning when I woke up my blood sugar was 121, and I didn't bolus for breakfast because I knew I was going to exercise. I ran 3-4 miles and afterwards my blood sugar was 266, which has NEVER happened. I power-walked for about 15 minutes and took my blood again and it was 278. I then changed my site, gave myself insulin and did elipticals for 15 minutes. My blood sugar was 239. I did eliptials for 15 more minutes and my blood sugar was 166. I came home and just took it and its 178. My breakfast was two peices of toast and a clemintine. This has neverrrr happened to me before and I was wondering if its happened to anyone else? Do you know how my blood sugar could have come up after exercising?
