Type 1 diabetes is when the pancreas doesn't produce any insulin (this differs from type 2, which is when the body doesn't produce enough insulin or insulin isn't effective). Type 1 diabetes can develop at any age but in most cases its before the age of 40. It is often called early onset or juvenile diabetes due to the fact it tends to occur from a young age. Type 1 tends to be caused by an autoimmune condition where the body's immune system attacks its own pancreatic cells (where insulin is produced)[1][2] Generic symptoms of type 1 diabetes include blurred vision, an increased need to urinate, potential weight loss and feeling fatigued[3].
