What happens when there is insufficient insulin or insulin resistance?

Type 2 diabetes occurs when not enough insulin is produced by the body for it to function properly, or when the body’s cells do not react to insulin – known as insulin resistance.

Someone with type 2 diabetes may be able to initially control their symptoms by eating a healthy diet and monitoring their blood glucose level.

In the next section, you will be introduced to our patient Seema who is the second of our two case studies on this course and is an example of someone diagnosed with type 2 diabetes.

The sequence of treatment in type 2 diabetes is attention to diet and lifestyle measures throughout life.

Someone with type 2 diabetes may need tablets and due to the progressive nature of the disease, tablets may become less effective and insulin injections may be needed.

The time at which insulin is needed can vary markedly between patients.

Type 2 diabetes is commonly, but not always, associated with obesity.

Did you know? Many people with type 2 diabetes are unaware that they have diabetes and by the time they are diagnosed they may already have evidence of damage to their bodies.
