Patients with type 1 diabetes are typically diagnosed during an episode of hyperglycemia, ketosis, and dehydration; this occurs most commonly in childhood or adolescence, before pregnancy. Type 1 diabetes is rarely diagnosed during pregnancy; in these cases, patients most often present with unexpected coma, because early pregnancy may provoke diet and glycemic control instability in patients with occult diabetes. A pregnancy test should be ordered in all reproductive-aged women admitted to the hospital for blood sugar management.
