How do you test for dawn phenomenon?

If you have persistently elevated blood sugar in the morning, checking your blood sugar once during the night — around 2 a.m. or 3 a.m. — for several nights in a row will help you and your doctor determine if you have the dawn phenomenon or if there’s another reason for an elevated morning blood sugar reading.

How can the Somogyi effect be reduced?

For Somogyi effect:

1. Decreasing the dose of diabetes medications that are causing overnight lows.
2. Adding a bedtime snack that includes carbs.

What is the most likely cause of the Somogyi effect?

The causes of Somogyi phenomenon include excess or ill-timed insulin, missed meals or snacks, and inadvertent insulin administration. Unrecognized posthypoglycemic hyperglycemia can lead to declining metabolic control and hypoglycemic complications.

How long does the Somogyi effect last?

Eventually the counter-regulatory mechanisms may become exhausted resulting in severe hypoglycemia. Hyperglycemia due to a Somogyi effect can sometimes persist for as long as 3 days after a single hypoglycemic episode.

What is the difference between Somogyi effect and dawn phenomenon?

If the blood sugar level is low at 2 a.m. to 3 a.m., suspect the Somogyi effect. If the blood sugar level is normal or high at 2 a.m. to 3 a.m., it’s likely the dawn phenomenon.

What does Somogyi effect mean?

According to the theory of the Somogyi effect, when insulin lowers your blood sugar too much, it can trigger a release of hormones that send your blood sugar levels into a rebound high.

What is Somogyi effect?

If the blood sugar level drops too low in the early morning hours, hormones (such as growth hormone, cortisol, and catecholamines) are released. These help reverse the low blood sugar level but may lead to blood sugar levels that are higher than normal in the morning.

How do you test for Somogyi effect?

The Somogyi effect can occur any time you or your child has extra insulin in the body. To sort out whether an early morning high blood sugar level is caused by the dawn phenomenon or Somogyi effect, check blood sugar levels at bedtime, around 2 a.m. to 3 a.m., and at your normal wake-up time for several nights.
