未治疗的1型糖尿病患者可以因为糖尿病酮症酸中毒(DKA)而死亡。治疗不当的1型糖尿病是慢性并发症(如双眼失明、肾衰竭、截肢和心肌梗死)的危险因素。强化血糖控制已被发现可以降低 1 型糖尿病患者微血管及大血管疾病发生率,[88]White NH, Sun W, Cleary PA, et al.

总体上,心血管疾病是糖尿病患者死亡和发病的主要原因。一项对 15 岁之前诊断为 1 型糖尿病的患者分析发现,30 岁之前的首要死亡原因是糖尿病的急性并发症。30 岁之后,心血管疾病为主要致死原因,但在这个年龄段,急性并发症导致的死亡仍很重要。[95]Gagnum V, Stene LC, Jenssen TG, et al.Causes of death in childhood-onset type 1 diabetes: long-term follow-up.

大部分 1 型糖尿病女性患者在充分的准备及治疗下,可以顺利妊娠。
