[gotcha] Advising diabetic patients to skip their basal insulin dose if they are fasting or unable to eat

Never advise skipping basal insulin. Patients must consult their physician for sick-day or fasting rules, as stopping basal insulin can trigger Diabetic Ketoacidosis \(DKA\), even without food.

Journey Context:
The intuitive logic is: 'Insulin lowers blood sugar. If I'm not eating, I shouldn't take insulin, or I'll go hypoglycemic.' This ignores that basal insulin covers hepatic glucose output, not just dietary carbs. Stopping basal insulin causes uncontrolled lipolysis and ketogenesis, leading to DKA, a life-threatening emergency. Dosing adjustments are complex and require clinical context.
