somogyi = rebound hyperglycemia due to hypoglycemia because of too much insulin given before sleeping

dawn phenom is due to homones being released according to circadian rhythm main hormone noted is GH. this causes a hyperglycemic state.

Okay..so the thing is that they both end up with hyperglycemia in the morning
So if we are not sure what do we do ?
The answer is somehow simple you Decrease the insulin at night then check am glucose..
If glucose is high it is Dawn
If the glucose is normal or decreased it is Somogyi
What matters here is that you shouldnt increase the insulin at night because if
the matter is Somogyi you will end up putting the patient in a coma..
Hope that will help you

But how do you differentiate it? Midnight blood sugar checking? Hypoglycemic symptoms with somogyi midnight?

In both Somogyi n Dawn phenomenon u ve hyperglycemia in early morning blood sugar......But da diffrence z Somogyi z due to excess insulin n Dawn z due to less insulin.right???
In Somogyi wen insulin z in excess while sleeping person ll ve hypoglycemia,so counter regulatory hormones ll take charge,n ll increase da glucose level.so wen person wakes up,Sugar level z much up...due to counter regulatory hormones.
While in Dawn there z less insulin to control sugar level si increased sugar level.simple z ds.okayy???
Nw regarding da treatment,we dnt know by morning blood sugar levels wether its somogyi or Dawn,so two options,wether v increase insulin to control Dawn or decrease insulin to control somogyi.......But think if v increase insulin,n pt. z wid somogyi then he ll get so severe hypoglycemia dat he can go into Coma...so v prefer to start treatment by decreasing insulin.....if pt.imroves then its somogyi confirmed..otherwise its Dawn phenomenon.
Okayyyy...dats wat i know from my little knowledge
