Diabetes-Related Emergencies
Number of Conditions: 3
Diabetic ketoacidosis (DKA)
Specialty: Emergency and Urgent Care
Category: Endocrine and Metabolic Emergencies
Sub-category: Diabetes-Related Emergencies
Symptoms:
nausea; vomiting; abdominal pain; rapid breathing; fruity-scented breath; confusion; excessive thirst; frequent urination
Root Cause:
DKA occurs due to insufficient insulin, leading to uncontrolled hyperglycemia, ketone production, and metabolic acidosis.
How it's Diagnosed: videos
Clinical evaluation, laboratory tests showing hyperglycemia (blood glucose >250 mg/dL), ketonemia, ketonuria, low bicarbonate levels (<18 mEq/L), and an elevated anion gap metabolic acidosis.
Treatment:
Immediate fluid resuscitation (IV fluids), insulin therapy, electrolyte replacement (especially potassium), and addressing precipitating factors (e.g., infections).
Medications:
Regular insulin (short-acting insulin for IV infusion to lower blood glucose and suppress ketone production), potassium supplements (for electrolyte correction), bicarbonate (in severe acidosis cases, though used cautiously).
Prevalence:
How common the health condition is within a specific population.
Common in individuals with type 1 diabetes and occasionally in type 2 diabetes under stress or illness.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Poor diabetes management, infections, physical or emotional stress, skipping insulin doses, undiagnosed diabetes.
Prognosis:
The expected outcome or course of the condition over time.
Favorable if treated promptly; mortality is low with appropriate intervention but rises if untreated.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Cerebral edema (especially in children), hypokalemia, cardiac arrhythmias, hypoglycemia, and multi-organ failure in severe cases.
Hyperosmolar hyperglycemic state (HHS)
Specialty: Emergency and Urgent Care
Category: Endocrine and Metabolic Emergencies
Sub-category: Diabetes-Related Emergencies
Symptoms:
severe hyperglycemia; extreme dehydration; altered mental status; weakness; seizures; coma
Root Cause:
Profound hyperglycemia (glucose >600 mg/dL) leads to severe osmotic diuresis and dehydration without significant ketone production.
How it's Diagnosed: videos
Laboratory findings of extreme hyperglycemia (>600 mg/dL), elevated serum osmolality (>320 mOsm/kg), normal or slightly elevated bicarbonate, and minimal or absent ketones.
Treatment:
Aggressive IV fluid replacement, insulin therapy to gradually reduce blood glucose, and addressing precipitating factors. Electrolyte monitoring and correction are also essential.
Medications:
Regular insulin (to lower glucose), electrolyte replacement solutions (potassium, magnesium, phosphate), and anticoagulants (e.g., heparin in immobile patients to prevent thrombosis).
Prevalence:
How common the health condition is within a specific population.
More common in older adults with type 2 diabetes, often triggered by infection, stroke, or myocardial infarction.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Advanced age, type 2 diabetes, dehydration, infections, poor diabetes management, use of glucocorticoids or diuretics.
Prognosis:
The expected outcome or course of the condition over time.
Can be life-threatening without prompt treatment; mortality rates are higher than DKA but decrease significantly with proper care.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Thrombosis, seizures, cerebral edema, acute kidney injury, and respiratory distress.
Severe hypoglycemia
Specialty: Emergency and Urgent Care
Category: Endocrine and Metabolic Emergencies
Sub-category: Diabetes-Related Emergencies
Symptoms:
shakiness; sweating; palpitations; confusion; irritability; seizures; loss of consciousness; coma
Root Cause:
Blood glucose levels drop dangerously low (<54 mg/dL) due to excess insulin, inadequate food intake, or increased physical activity.
How it's Diagnosed: videos
Confirmed by measuring blood glucose (<70 mg/dL, with severe symptoms typically at <54 mg/dL) and rapid resolution of symptoms after glucose administration.
Treatment:
Immediate administration of glucose (oral if conscious, IV dextrose if unconscious), glucagon injection for emergencies, and addressing underlying causes.
Medications:
Dextrose (IV infusion to rapidly raise blood glucose), glucagon (injectable for emergency situations), and long-term adjustments to insulin regimens or oral diabetes medications.
Prevalence:
How common the health condition is within a specific population.
Frequent in individuals with diabetes on insulin or sulfonylureas, especially in those with tight glucose control.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Insulin or sulfonylurea use, skipping meals, excessive alcohol consumption, prolonged fasting, or physical exertion.
Prognosis:
The expected outcome or course of the condition over time.
Recovery is rapid with appropriate treatment; recurrent episodes can lead to impaired awareness of hypoglycemia.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Seizures, loss of consciousness, brain damage from prolonged severe hypoglycemia, and potential cardiovascular events.
