When to consider insulin

For people with type 2 diabetes, the decision to consider insulin therapy must be made with a healthcare provider. All people with type 1 diabetes need to take insulin because their bodies no longer make any insulin.^,

Generally, people with type 2 diabetes begin to take insulin when their bodies can't make enough insulin anymore and their blood glucose levels start to go up. However, some people with type 2 diabetes may need to start taking insulin right away.
