Type 1 diabetes occurs when the body’s immune system attacks and kills the beta cells in the pancreas that make insulin.
We don’t yet know what causes type 1 diabetes.
However, genetics and environmental influences may be factors.
Type 1 diabetes generally develops in childhood or adolescence, but can develop in adulthood.
Type 1 diabetes is treated with insulin, given as daily insulin injections or via an insulin pump.
Latent autoimmune diabetes of adults (LADA) is a slow progressing form of type 1 diabetes that can be managed in the early stages without insulin therapy.
Many people with LADA are misdiagnosed with type 2 diabetes.
The exact cause of type 1 diabetes is unknown.
What is known is that your immune system – which normally fights harmful bacteria or viruses – attacks and destroys your insulin-producing cells in the pancreas. This leaves you with little or no insulin. Instead of being transported into your cells, glucose builds up in your bloodstream.
