Corrected sodium level When hyperglycemia is present, the underlying sodium concentration (corrected sodium concentration) can be estimated by adding 1.6-2.4 mEq/L (average of 2 mEq/L) to the reported sodium concentration for every 100 mg/dl increase in plasma glucose above 100 mg/dl. E.g. In a patient with Na+ level, 145 and…

Somogyi effect and Dawn Phenomenon – Mnemonic
Both Somogyi effect and Dawn phenomenon are the cause of MORNING FASTING HYPERGLYCEMIA. Mnemonic: Somogyi = So Much InsulinDawn = Down Insulin a. Somogyi effect: Excess exogenous insulin → Middle night hypoglycemia → Release of counter-regulatory hormones → Rebound morning hyperglycemia b. Dawn effect: Normal release of morning hormones (growth…
