Mr Ng is diabetic person, he usually has good blood sugar level control as he checks regularly after food. But one day he decides to check his blood sugar level before breakfast – the level shows 10 mmol/L! – the high level shocks him (refer to table 1). What’s the explanation behind a spike in early morning blood sugar levels? We explore the two common reasons of high blood sugar levels in the morning:

The dawn phenomenon is a normal rise in blood sugar as a person’s body prepares to wake up. In the early morning hours, hormones (growth hormone, cortisol, and catecholamines) cause the liver to release large amounts of sugar into the bloodstream. For most people, the body produces insulin to control the rise in blood sugar. If the body doesn’t produce enough insulin, blood sugar levels can rise. This may cause high blood sugar in the morning (before eating).
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.
An example of the Somogyi effect is:
Yes, but a Somogyi effect may be the more harmful condition as blood sugar levels go much lower. Both events bring about complications related to low and high sugar levels.
Check blood sugar levels at bedtime, and at your normal wake-up time. If the levels are “off target”, you might be suffering from either the dawn phenomenon or the Somogyi effect. (See Table 1)
However, to distinguish if one is suffering from either the dawn phenomenon or the Somogyi effect, seek help from an endocrinologist (a specialist in diabetes).
