Type 1.5 diabetes is a relatively unfamiliar form of diabetes that many people may not recognize or fully understand. This form can often be originally mistaken for type 2 diabetes due to overlapping symptoms.

To gain a better understanding of the differences between the forms, continue reading.

What is Type 1.5 Diabetes?

Type 1.5 diabetes, also known as Latent Autoimmune Diabetes in Adults (LADA), is a form of diabetes that typically begins in adulthood, often after the age of 30. Unlike type 1 diabetes, which progresses rapidly and is known by an immediate decrease in insulin production, LADA develops more gradually. It combines features of both type 1 and type 2, which is why it’s sometimes referred to as type 1.5. In LADA, the pancreas gradually loses its ability to produce insulin due to an autoimmune attack, similar to type 1. However, the onset is slower and can initially mimic type 2 diabetes, especially since it often appears later in life. This gradual onset can lead to the original misdiagnosis as type 2 diabetes.

To accurately diagnose LADA, healthcare providers can test for specific autoimmune antibodies. This form of diabetes is relatively uncommon, affecting approximately 2 – 12% of all individuals diagnosed with diabetes.

Differentiating between the Types

The different types of diabetes can become confusing due to their overlapping characteristics. To help clarify their differences, refer to the chart below, which outlines the key features of several common forms of diabetes. This visual guide will assist you in distinguishing between them more easily

Risk Factors

Preventing this form of diabetes can be challenging since it is an autoimmune disease. However, being aware of certain risk factors may help reduce your likelihood of developing this form of diabetes later in life. Some Key risk factors include:

  • Obesity
  • Low Birth Weight
  • Low Physical Activity
  • Psychosocial stress
Summary

Type 1.5 diabetes, also known as Latent Autoimmune Diabetes in Adults (LADA), can be more challenging to diagnose than type 1 or type 2 diabetes. Understanding the distinct characteristics can help to differentiate it from other forms of diabetes. Familiarizing yourself with the risk factors and symptoms associated with LADA can enhance your ability to recognize and address it, especially if symptoms emerge later in life. By being vigilant and informed about LADA’s signs, you can better monitor your health and seek timely intervention, even if you are older and symptoms might initially seem more aligned with type 1 diabetes.
