Connect symptoms and examination findings to a differential, targeted investigations, initial priorities and reassessment.
Diabetes assessment
Diabetes may present through symptoms such as thirst, polyuria and weight loss or through testing in an at-risk person. Diagnostic criteria use standardized glucose or HbA1c methods with confirmation when required by the clinical setting. HbA1c reflects longer-term glycemia but can be misleading with altered red-cell survival and some hemoglobin conditions. Classification considers the mechanism and clinical course; body size alone does not reliably distinguish type 1 from type 2 diabetes.
Long-term care
Management combines education, nutrition, activity, individualized medicines and monitoring with cardiovascular and complication prevention. Review kidney function, blood pressure, feet, eyes and treatment burden. Insulin is essential in type 1 diabetes; illness management requires an individualized plan rather than casual omission. Discuss hypoglycemia, safe medicine use and how to obtain help. Targets and therapies depend on circumstances, comorbidity, preferences and current guidance.
Hypoglycemia
Sweating, tremor, hunger, palpitations, confusion or reduced consciousness may reflect low glucose, but symptoms can be atypical. Check glucose promptly in altered consciousness and treat clinically significant hypoglycemia without avoidable delay. The route of correction depends on consciousness, swallowing safety and available trained care; never give oral intake to someone unable to swallow safely. Recheck response and investigate the cause because long-acting medicines or renal impairment may lead to recurrence.
DKA and HHS
Diabetic ketoacidosis combines diabetes or hyperglycemia with ketosis and metabolic acidosis. It can occur without extremely high glucose, including with SGLT2 inhibitor exposure. Hyperosmolar hyperglycemic state features marked hyperglycemia and hyperosmolality with less prominent ketosis, but overlap occurs. Both can cause profound dehydration and organ dysfunction. Emergency care uses protocol-based fluids, insulin, electrolyte management and treatment of the precipitant with frequent reassessment.
Potassium and prevention
Serum potassium may initially be normal or high in DKA despite total-body depletion. Insulin and correction of acidosis can lower it, so potassium status affects the treatment sequence and monitoring. Resolution is not defined by glucose alone; ketosis, acid-base state and clinical recovery matter. Infection, missed treatment and other stressors can precipitate crises. Before discharge, review access, technique, sick-day guidance and support to reduce recurrence.
High-Yield Revision
- Check glucose promptly in altered consciousness.
- DKA can occur without extreme hyperglycemia.
- Potassium and ketone monitoring are central to crisis care.
Common Exam & Concept Pitfalls
- Do not give oral glucose to an unsafe swallow.
- Do not call DKA resolved from glucose normalization alone.
