He subsequently developed severe muscle pain (myalgia) accompanied by a pronounced and persistent elevation of plasma creatine kinase, indicating rhabdomyolysis, and deranged liver function, suggestive of hypoxic hepatitis. These symptoms lasted for several weeks after the race.<\/p>\n<p style=\"text-align: justify;\">\u00a0<\/p>\n<p style=\"text-align: justify;\">I don\u2019t know exactly what these complications are but I got the point \u2013 people using insulin should not undertake prolonged intensive exercise after severe hypoglycemia.<\/p>\n<p style=\"text-align: justify;\">\u00a0<\/p>\n<p style=\"text-align: justify;\">I know this may sound obvious, and it would be easy to dismiss the guy as an idiot, but I hate to tell you how many times I\u2019ve gone running after a nighttime low followed by a rebound high. What usually happens in these cases is that I wake up in the 200\u2019s go running, and then find myself crashing after 2-3 miles.<\/p>\n<p style=\"text-align: justify;\">\u00a0<\/p>\n<p style=\"text-align: justify;\">Although I know my blood sugar levels tend to drop quickly after nighttime hypoglycemia, especially when exercising, I don\u2019t think twice about it and stick to my plan. This is true, while training for a marathon or just running for exercise (although I\u2019m usually training for a marathon). I have called off some runs after a severe low but I have to admit that I probably wouldn\u2019t give up a marathon if I had suffered a low the night before.<\/p>\n<p style=\"text-align: justify;\">\u00a0<\/p>\n<p style=\"text-align: justify;\">After all these years of running with diabetes, I\u2019ve learned to check my blood sugar two miles into my runs, expecting my blood sugar to drop. Nighttime lows are different, though, and they can offset everything the next day.\u00a0 On an average day my blood sugar will drop from around 140 to 90 during the first 2-3 miles of a run. But on a post nighttime low I can start in the 200\u2019s and find myself 2-3 miles down the road trying to treat a low somewhere in the fifties. Another thing the tends to happen to me after a nighttime low is that even if I catch myself in the 70\u2019s or 80\u2019s, I need to take another gel two miles later. There have been times when I\u2019ve had to stop running after a few miles because my blood sugar just wouldn\u2019t stop plummeting.<\/p>\n<p style=\"text-align: justify;\">\u00a0<\/p>\n<p style=\"text-align: justify;\">At this point you may ask yourself why I would ever go out running after a low. There are two parts to the answer. The first is my need to keep on going, stick to my schedule, and not give in to diabetes. The second is that things don\u2019t always go so wrong. Sometimes all that is needed is an extra gel and I find myself having an excellent run. I imagine that this has something to do with the severity of the nighttime low and probably other factors, too.<\/p>\n<p style=\"text-align: justify;\">\u00a0<\/p>\n<p style=\"text-align: justify;\">Another problem is that I\u2019m not always aware of the nighttime lows since apparently thanks to gluconeogenesis, many times I wake up high (or at least I did until <a href=\"https:\/\/asweetlife.org\/michael\/blogs\/personal-blogs\/patient-power-i-discovered-metformin-myself\/27472\/\">I started taking metformin<\/a>).\u00a0 I don\u2019t know if it\u2019s a rebound or just a regular morning high until I\u2019ve gone running and crashed.<\/p>\n<p style=\"text-align: justify;\">\u00a0<\/p>\n<p style=\"text-align: justify;\">Until now, though, I\u2019ve considered nighttime hypoglycemia and its effects obstacles to my running schedule, I did not consider them a dangerous situation I needed to avoid. Maybe it\u2019s time to think less about my running schedule and my weekly millage and more about the serious effects and dangers of hypoglycemia so I can continue to live and run for many years.\u00a0<\/p>\n<p style=\"text-align: justify;\"><strong><br
