Somogyi effect

Last reviewed 01/2018

The Somogyi effect is a phenomenon where hypoglycaemia is followed by hyperglycaemia as a result of an over-reaction to the low sugar. It is usually seen in children with insulin dependent diabetes mellitus, especially where an insulin with a long acting component is being used.

Collection of urine in fractions through the day may demonstrate glycosuria worse at some times than at others.
