Type 2 diabetes could be predicted up to 19 years in advance, claim researchers at Lund University in Sweden. The researchers identified high levels of a particular protein in the blood, called follistatin, as a predictor of a person鈥檚 likelihood of developing type 2 diabetes (regardless of other risk factors).

鈥淭his study shows that follistatin has the potential to become an important biomarker to predict future type 2 diabetes, and it also brings us one step closer to the understanding of the mechanisms behind the disease,” said Dr. Yang De Marinis, associate professor at Lund University and lead author of the study. 

Follistatin helps break down body fat, which in turn increases fat build-up in the liver that can lead to fatty liver and type 2 diabetes. Since follistatin levels fluctuate according to food consumption and activity levels, Dr. Yang De Marinis emphasises the usual advice for preventing diabetes: 鈥淏alanced meals, eat[ing] healthy and regular exercise.鈥� 

Next, the team are looking to develop a diagnostic tool using artificial intelligence that could assess a person鈥檚 blood and determine a 鈥榬isk score鈥� for diabetes based on follistatin (and other biomarker) levels.

Key Messages

• Researchers in Sweden discover that type 2 diabetes could be predicted up to 19 years in advance (regardless of age, weight, or activity levels) by measuring levels of a blood protein called follistatin.
• Follistatin helps break down body fat, which in turn increases fat build-up in the liver that can lead to fatty liver and type 2 diabetes. 
• Follistatin levels fluctuate according to food consumption and activity levels, so it is suggested to follow healthy eating and exercise recommendations to prevent diabetes onset.
• Next, researchers are hoping to develop an AI-generated diagnostic tool using follistatin levels as a measurement for diabetes susceptibility.
