Glycogen Storage Diseases — The High-Yield Way

Von Gierke, Pompe, Cori, McArdle — four diseases that become unforgettable once you see the warehouse logic behind them. Liver glycogen is the body's public bank; muscle glycogen is a private vault. Learn which enzyme is missing, and the symptoms, labs and exam traps derive themselves: fasting hypoglycaemia with lactic acidosis and gout, the floppy baby with the enormous heart, the milder Cori picture with intact gluconeogenesis, and McArdle's second wind with a flat lactate rise.
