What Is the Somogyi Effect?

Controversy over Somogyi Effect

Diabetic patients and doctors usually mention the term “Somogyi effect”. However, there is not much scientific proof for this theory. For instance, some studies suggested that high blood sugar in the morning is likely to occur in those who do not take sufficient insulin the night before. Those with rebound hyperglycemia also seem to have lower levels of glucagon, cortisol, and growth hormone than others. A study in 2007 on people with type 1 diabetes found no proof of the Somogyi effect. Nevertheless, another study reached a conclusion that the Somogyi effect was the most common reason for high blood pressure in the morning in people with type 1 diabetes who do not manage levels of blood sugar effectively.
