Let's start with a definition (sourced from Diabetes Canada):

The Somogyi effect, also known as rebound hyperglycemia, is a phenomenon where a low blood sugar episode (hypoglycemia) is followed by a high blood sugar episode (hyperglycemia).

This occurs when a person with diabetes experiences a low blood sugar event, often during the night, which triggers the release of counter-regulatory hormones (like glucagon, adrenaline, cortisol, and growth hormone) that raise blood sugar levels, leading… read more

Members expressed warm gratitude for an educational post explaining the Somogyi effect, with several sharing how they've learned to recognize the difference between Somogyi-triggered rebounds and the Dawn Phenomenon on their CGM graphs. Many members related to experiencing nighttime drops that self-correct through hormonal responses, with one member sharing how Ozempic helped quiet their liver's overreaction to Dawn Phenomenon and another discussing their midnight eating habits. A recurring theme was appreciation for how CGMs reveal these patterns honestly and help members understand their body's overnight glucose regulation, along with the practical relief of knowing that eating breakfast can actually help lower rising morning numbers.

@A DiabetesTeam Member that's true and even from the graph I posted you can see that I never went below the 3.9 mmols/70 point (barrier) to a full on "low"

But I was asleep and dropping somewhat quickly about 3AM - I didn't wake up, didn't grab a glucose tab or bit of juice - I slept through the entire event and didn't even know until I looked at the graph this morning

The "bump" took me back up into a sugar safe range in the high 5's (mmols) or probably raised me from "close to 70" up to about 110 points in about 20 minutes and then (left things alone)

If I had have woken with "night sweats" and disoriented and drank 4oz of Orange Juice, I would have got close to the same effect

But one of these days my BG might just keep heading South and I simply won't wake up - and maybe that wouldn't be a terrible way to go either 😁

I'm a little lazy about putting comments in my graph. But if you look close, somewhere between 7 and 8 AM the Dawn Effect starts kicking in (you noticed that) and my numbers are rising modestly - I got up about 8:30, ate about half hour later so that 8.1 mmols at 9:30'ish was me "peaking" from eating an English Muffin/Peanut Butter for breakfast about 9 o'clock, on top of the Dawn Effect which was present

I love CGM's, they tell you "everything" and you can't lie to them - they "catch you" when you are fibbing....

@grahmlamb my symogies are usually self correcting as well. But thats why I leave the alarms on!
Dawn effect was a real problem would go as high as 180 before I got up . Hard to get leveled out when you start the day that high. But the ozempic seems to have quieted my liver from over reacting like that!

My understanding is it does mot have to be a true low(below60) but just a sudden drop.

6 hours between your low and the second rise. So the second rise Looks more like dawn effect. Although the interstitial fluid may have a longer delay.
