Recently,for some reason,I had to shift my regular evening walk to morning walk.But to my shock,my sugar level after exercise, still fasting,was exceptionally high.Sugar level after exercise should be lower,right?In my case, it spiked. I was intrigued and did some searching on the net.I got following understanding.
I am on insulin and after dinner at 9.00 pm,the insulin supply would be near zero by next morning.So,while I walk for about 35 minutes,the body releases glucose into the bloodstream to meet the increased energy demand.Sugar levels shoot up due to absence of insulin.Is my understanding correct? If so,what is the remedy?
I thought of having some nourishment before I start walking,but due to fear of adding additional calories,I desisted.
Forum,please share your similar experiences and advise.
I have somewhat similar experience. At bedtime, my blood sugar level was 96 and in the morning it shot up to 122 although fasting whole night. Even after the morning walk, the blood sugar level remained high. Eventually, it does come down few hrs after breakfast.
There can be one of the two reasons for this - 1. Somogyi Effect 2. Dawn Phenomenon.
One has to first confirm which factor is responsible for the rise in blood sugar.
If your blood sugar level around 3 to 4 am becomes lower than bedtime level, it is Somogyi effect.
If your blood sugar level around 3 to 4 am remains more or less same as bedtime level, it is Dawn Phenomenon.
In the first case ( Somogyi) eating some snacks at bedtime which releases sugar slowly may help.
The second case ( Dawn phenomenon) is more difficult to control at least in my experience. One can use slow acting medication which prevents lever to release glucose, but I am trying to fix it by natural means. Still, work in progress. In my case, it is not very high.
