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 hidden form of diabetes, known 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.

A recent study suggests that up to 14 per cent of people diagnosed with type 2 diabetes may actually have LADA.

LADA is a distinct form of diabetes, medically recognized since 1993, and accounts for 3-12 per cent of all cases of diabetes in adults.

Type 1.5 diabetes, or latent auto-immune diabetes (LADA), is not a new form of diabetes, but it is somewhat rare.

LADA is characterized by an excess of sugar, or glucose, in the blood, similar to type 1 and 2 diabetes.

Author's summary: Type 1.5 diabetes affects millions of adults worldwide.
