The Somogyi phenomenon in insulin-dependent diabetics.

Insulin-dependent diabetics at times of changing stress levels require alterations in their insulin dosage. Determination of the required insulin dosage is not a precise science. At these times, the diabetic may experience insulin overdosage with a resulting rebounding hyperglycemia (Somogyi phenomenon). Adequate data collection and a systematic approach to documentation of the data by either the nurse or the patient will provide both the physician and the nurse with the means to recognize the occurrence of the Somogyi phenomenon. The author recommends a tool that can be used to enhance recognition of the occurrence and provide clinical criteria to evaluate its presence.
