Type 2 diabetes remission restores pancreas size and shape – study

Going into remission of type 2 diabetes through a low-calorie, weight management programme can restore the pancreas to a normal size, a new study suggests.
People with type 2 diabetes have a pancreas that is around 20-30% smaller than people without the condition, and it is more irregular in shape.
Researchers say that until their research it had not been clear if this is the cause of type 2 diabetes, or a result of having the condition, or whether it is possible to restore the pancreas to a healthy size and shape.
DiRECT, a trial funded by charity Diabetes UK, indicates that more than a third (36%) of people with type 2 diabetes who took part in the low-calorie, weight management programme were still in remission two years later.
The researchers tracked changes in the pancreases of 64 participants in the DiRECT trial.
Using MRI scanners, they measured the volume, shape and amount of fat in the pancreases, and followed these changes over two years.
According to the study, presented at the European Association for the Study of Diabetes Conference, researchers observed for the first time that the size of the pancreas in people who were in remission for two years had increased by 20% – returning to almost normal size.
They also saw that, along with a drop in the amount of fat in the pancreas, the very irregular borders of the pancreas returned to normal.
The pancreas did not increase in volume to the same extent in people who did not go into remission, and they showed very little change in pancreas shape, the scientists found.
They say the results are the first evidence that remission from type 2 diabetes causes positive changes to the structure of the pancreas.
Researchers say their work, due to be published in The Lancet Diabetes and Endocrinology highlights the importance of weight loss – specifically a weight loss of 10-15kg – in bringing about remission.
This specifically reduces the amount of fat in the pancreas, leading not only to beta cell recovery and increased insulin production but also restoration of the whole organ.
Professor Roy Taylor, of Newcastle University – who led the work, said: "It will be enormously encouraging for anyone with type 2 diabetes to learn that their small pancreas can return to normal size.
"Knowing what a treatment actually does inside the body is both motivating and reassuring."
Dr Elizabeth Robertson, director of research at Diabetes UK, said: "Our landmark DiRECT trial has revolutionised thinking about type 2 diabetes – we no longer consider it to be a life-long condition for everyone, and know that remission is possible for some people.
"And we're continuing to learn more about remission of type 2 every day.
"These new findings help to build a clearer picture of the biology behind remission, and how the health of the pancreas can be restored by weight loss.
"However, we still have questions to answer, such as why remission isn't possible for everyone.
"As NHS England begins its trial of a DiRECT-inspired weight management remission programme, it is key that we continue to explore these questions to make remission a possibility for as many people as possible."
