[the Dawn Or Somogyi Phenomenon? High Morning Fasting Blood Sugar Values In Young Type-1 Diabetics].

Abstract High blood sugar levels in the morning in juvenile type 1 diabetics may be caused by a Somogyi phenomenon (counter-regulation after nocturnal hypoglycaemia) or insulin resistance in the morning hours (dawn phenomenon). To enable differentiation between the two, 1,562 blood sugar profiles (24 h, 3 h, 6 h) were determined in 161 children and juveniles (74 boys, 87 girls; mean age 10.8 [1.0-19.7] years) with type 1 diabetes mellitus. In accordance with the mechanism of the dawn phenomenon there was a close positive correlation between the blood sugar levels in the night and morning (r = +0.696; P less than 0.0001); the mean fasting blood sugar level was about 60 mg/dl above the 3 h value. Low nocturnal blood sugar levels as a possible cause of a high morning blood sugar (greater than 250 mg/dl) was demonstrated in fewer than 1% of profiles. On the other hand, the probability of nocturnal hypoglycaemia rose exponentially in the presence of low morning fasting blood sugar levels. Thus, if the morning level was below 80 mg/dl, the blood sugar levels at 3 h was below 50 mg/dl in 41.2%. This indicates that high morning blood sugar levels result from the dawn phenomenon and require Continue reading >>

    Morning Glucose Levels - Abby

    Hi All,
    My 7 yr. old Yorki-Poo Abby was diagnosed this week with diabetes. She started last Thursday drinking thorugh the night and again Friday night (up all night wanting off the bed) and Saturday night she was in the ER Vet. Blood sugar was 606 and mild ketones. She was hospitalized and put on a "regular" insulin drip. Monday morning she was transfered to her Internal Medicine Specialist (she has several other endocrine problems - hypothyroid, Fanconi Syndrome) and was diagnosed with pancreatitis which is what they think caused the diabetes. She spent three nights at the specialist hospital and came home this afternoon. I have done lots of research and read lots on this board. I gave her first insulin shot tonight, that was the easy part. She is hungry but doesn't want to eat her Hills W/D wet food. I mixed in some broth and she ate a good amount of it. She wanted our other dogs food so bad.
    The vet started her on 4 units of insulin. We go back in a week to recheck her.
    I will probably be purchasing a glucose monitor, what types are recommended? The vet said there is a vet glucose monitor that is expensive but has a truer reading.
    So what is next? What things should I start doing? What food is good for diabetes and pancreatitis? Vet wrote a script for Hills G/D.
    I am feeling a bit overwhelmed but I can manage that, I just want to get her regulated and healthy...

    Hi Jaime,
    Welcome to you and Abby!
    I always recommend that people just starting to home test start out with a meter for people first - they are inexpensive and the strips are much less expensive too and the strips are the real cost over the long run. You can often get a meter free or almost free, sometimes after a rebate and sometimes directly.
    For small dogs, I like the Freestyle meters. They require a tiny drop of blood and seem to be highly accurate with small dogs.
    The people meters will typically read the blood sugar somewhat lower than it actually is. How much lower (and sometimes I have seen them be right on in small dogs) depends on the meter and your dog. Our OneTouch Ultra was a very reliable 30-40 points low and I just adjusted his readings.
    The thing is... you don't really need to know if the blood sugar is 150 or 180. The decisions made based on those two readings would be the same. Similarly, you don't really need to know if the blood sugar is 300 or 350. Again, the decision you would make based on the reading would be the same.
    So the inexpensive meter gives you a chance to get to be a pro at home testing for very little money and gives you the information you need to determine how the regulation is going.
    Then, if you want the more accurate meter once you've got testing mastered, go for it. The meter alone will run around $100 and the strips are probably twice as expensive or more than the people meter strips. That meter is the AlphaTrak.
    There are links to the meters commonly used with dogs on the main website: http://www.k9diabetes.com/monitoring.html.
    Home testing gives you the best information to manage her diabetes well so it's definitely worth it.

    Hi abby
    I am by no means an expert but I have been where you are. Buster has pancreatitis also with his diabetes. First thing is that my vet had him on the science diet w/d wet and dry for a while. It really doesnt fill buster up but he is getting use to it. Now we just do the dry. This food is excellent for him. He doesnt get sick at all. With the pancreatitis he threw up and lost alot of weight. Buster has steriod induced diabetes because his other vet kept treating him with steriods for his throwing up which infact was his pancreatitis. At first we had to slowly get him off the steriods, and gave him anti-nausa pills which helped. We had buster in the vet for 3 weeks everyday and we took him home at nite. My vet was very careful at what she gave him in the beginning because he was a mess.
    I have one touch meter for buster to check his BG. You can get that free on the website. The strips are expensive though.
