Hidden 'type 1.5' diabetes affects millions of adults. Here's how to spot it | BBC Science Focus Magazine

Understanding Type 1.5 Diabetes

Millions of adults are affected by a lesser-known form of diabetes, often referred to as "type 1.5" or Latent Auto-Immune Diabetes (LADA).

LADA shares similarities with type 1 and type 2 diabetes, making it challenging to identify and often leading to misdiagnosis. In fact, a recent study suggests that up to 14% of people diagnosed with type 2 diabetes may actually have LADA.

Type 1.5 diabetes, or LADA, is a distinct form of diabetes that has been medically recognized since 1993, accounting for 3-12% of all adult diabetes cases.

LADA is classed as a disorder of too much sugar, or glucose, in the blood, similar to type 1 and 2 diabetes.

Author's summary: Type 1.5 diabetes affects millions, often misdiagnosed as type 2.
