Chronic Somogyi rebound
From Wikipedia, the free encyclopedia
Chronic Somogyi rebound is a contested explanation of phenomena of elevated blood sugars experienced by diabetics in the morning. Also called the Somogyi effect and posthypoglycemic hyperglycemia, it is a rebounding high blood sugar that is a response to low blood sugar.[1] When managing the blood glucose level with insulin injections, this effect is counter-intuitive to people who experience high blood sugar in the morning as a result of an overabundance of insulin at night.
This theoretical phenomenon was named after Michael Somogyi [suh MOE jee], a Hungarian-born professor of biochemistry at the Washington University and Jewish Hospital of St. Louis, who prepared the first insulin treatment given to a child with diabetes in the US in October 1922.[2] Somogyi showed that excessive insulin makes diabetes unstable and first published his findings in 1938.[3]
Compare with the dawn phenomenon, which is a morning rise in blood sugar in response to waning insulin and a growth hormone surge (that further antagonizes insulin).
