Diabetes Mellitus Lab

Run a fictional patient's whole day of glucose and insulin, practice unlimited questions at three levels, race the clock sorting crises, insulins, drugs and tasks, and reason through bedside scenarios. Nothing here is graded.

Part 1: Glucose Day Explorer

Teaching modelA fictional adult with type 1 diabetes eats 60 g of carbohydrate at 7:30, 12:30 and 18:30. The curves come from a simplified model tuned so that 1 unit of rapid-acting insulin covers about 15 g. Real patients vary widely; this is for learning patterns, not for dosing anyone.

Readouts for the 24 hours shown

How the model works: the liver adds glucose all day; meals add glucose over about 2 hours; each unit of insulin removes glucose along that insulin's action curve. Glargine acts flat over 24 hours; NPH given at 10 p.m. peaks around 4 a.m. Prednisone at 8 a.m. adds glucose through the afternoon and evening; a walk after dinner removes some. Below 70, the body fights back a little; above 180, some glucose spills in urine.
