Diabetes and Metabolic Emergencies
Manage dysglycaemia, diabetic emergencies and long-term vascular, renal, retinal and foot risk.
How to prepare for MRCP(UK) Part 1
Use the official likely question distribution to plan breadth, then connect mechanisms, patterns and investigations to one most appropriate answer.
Core concepts
Concept 1
Diabetic emergencies require simultaneous resuscitation, biochemical monitoring and treatment of the trigger.
Exam cue: Name the metabolic syndrome and immediate threat.
Concept 2
Long-term targets are individualised by comorbidity, hypoglycaemia risk and treatment burden.
Exam cue: Review fluids, insulin, electrolytes and response together.
Risk pitfalls and guardrails
Correcting glucose while overlooking potassium or osmolality.
Guardrail: Do not select an option merely because it is true; choose the one that best answers the exact stem and fits the full pattern.
Using one target for every patient.
Guardrail: Do not select an option merely because it is true; choose the one that best answers the exact stem and fits the full pattern.
Memory anchors
What defines DKA management?
Fluids, fixed-rate insulin, potassium surveillance, ketone and acidosis resolution, and trigger treatment.
What distinguishes HHS?
Profound hyperglycaemia and hyperosmolality with severe dehydration and limited ketoacidosis.
What follows hypoglycaemia treatment?
Confirm recovery, give sustained carbohydrate when appropriate and identify the cause.
What belongs in diabetes surveillance?
Kidneys, eyes, feet, nerves, cardiovascular risk and medicine harms.
What makes sick-day guidance safe?
Monitoring, hydration, medicine-specific advice and explicit escalation thresholds.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
