What feature is commonly associated with type 1 diabetes mellitus at presentation?

• A. Hyperosmolar hyperglycemic state
• B. Diabetic ketoacidosis
• C. Obesity and metabolic syndrome as the presenting pattern
• D. Hypoglycemia without dehydration

Answer: (B)

Diabetic ketoacidosis is the presentation most characteristic of new-onset type 1 diabetes. When insulin is absent, glucose cannot enter many tissues and the body switches to fat breakdown for energy, producing ketone bodies that cause a high anion gap metabolic acidosis. The result is dehydration from osmotic diuresis, along with polyuria, polydipsia, weight loss, and often nausea or abdominal pain, sometimes with tachycardia and rapid breathing. Lab findings typically show hyperglycemia, ketonemia/ketonuria, metabolic acidosis, and electrolyte disturbances with a total body potassium deficit despite possible normal or high serum potassium. This presentation helps distinguish type 1 from type 2 patterns, where obesity and metabolic syndrome are more common and hyperosmolar hyperglycemic states are more typical, and it’s not usually a scenario of hypoglycemia with dehydration.
