I have had high blood sugar readings 200-380 consistently for the past two weeks. Doctor says to continue checking sugar and keep a log. Doctor says it could be the "down phenomenon" or the "somogyi effect." My blood glucose levels are high when I go to bed, higher when I wake up and stay high throughout the day. Even after walking for an hour, glucose level went from 234 down to only 202. I have decreased my food intake with no significant change in levels. I have increased insulin dosage with no significant change. I have had type 1 diabetes for 20 years and have never had high blood sugar levels for such an extended period of time. My glyco-hemoglobin level is 7.2, the highest it has ever been. Need advice.
Sorry to hear your having problems. What are you eating would be my first question and how much and how many times a day? Walking is great for lowering the BS.
Are you over weight?
Do you test and how often?
It would help us to know more info to try and help you.
If you can walk after every meal maybe just 1-15 min if you can. If you bs is high befor you eat walk first and then after.
Try and let us know exactly what your eating.

First of all, Dawn phenomenon is where you blood sugar raises overnight in preparation for the day. If you haven't had a problem with this before, then it's probably not that. While it happens to everyone to some extent or another it probably wouldn't affect you all day long. The somogyi effect is when your glucose goes low and the liver over compensates and brings you too high afterwards.
From the sound of it, you have become insulin resistant, sort of like type 2. What is your carb intake and what type of carbs are you eating? I know of several type 1s who take metformin to help with this and it makes their glucose easier to control. Try discussing this with your doc also.
