For a long time, most doctors and scientists believed that high blood sugar levels were the main cause of health problems in people with type 2 diabetes. Controlling glucose levels has been the primary goal in treating this condition for decades.
However, new research from the University of Kentucky has just turned that idea upside down. Their study, led by Dr. Barbara Nikolajczyk and published in Cell Metabolism, reveals that the real cause of inflammation in type 2 diabetes isn’t just glucose—it’s actually linked to problems with mitochondria and certain fats.
Mitochondria are tiny structures inside cells that act like power plants. They produce energy for the body by breaking down nutrients. When mitochondria are not working properly, it can lead to a lot of health issues, including chronic inflammation.
Inflammation is a big problem for people with type 2 diabetes because it damages cells and tissues, making it harder for the body to use insulin properly.
For years, scientists thought that inflammation in type 2 diabetes was mostly driven by high glucose levels. It seemed logical—after all, people with diabetes have trouble processing sugar, and too much sugar in the blood can cause damage.
But the University of Kentucky researchers decided to dig deeper. They wanted to understand what was really happening inside the immune cells of people with type 2 diabetes.
They began by studying how these immune cells use energy. Normally, cells use glucose as their primary energy source through a process called glycolysis. But when the researchers looked closely, they found that glucose wasn’t the main problem.
Instead, the real culprits were changes in mitochondria and an increase in fat derivatives—substances created when the body breaks down fats. These fats were feeding the immune cells and driving the inflammation that causes so many complications in type 2 diabetes.
This is a huge discovery because it changes how we understand and treat the disease. Up until now, most diabetes treatments have focused on lowering blood sugar levels.
People are often prescribed medications to control glucose, and they are told to follow strict diets to avoid sugar spikes. But this study suggests that even if blood sugar is well-managed, inflammation can still happen if mitochondrial problems and fat levels aren’t addressed.
The researchers believe this is why some people with type 2 diabetes continue to experience health problems even when their blood sugar is under control. Mitochondrial dysfunction and fat-related inflammation can still damage tissues and organs, making the disease progress.
This could explain why some people with well-managed diabetes still suffer from complications like nerve damage, heart problems, and kidney issues.
The findings are opening the door to new types of treatments. If inflammation is really driven by mitochondrial problems and fats, then therapies that target these areas could be far more effective than simply controlling glucose.
For example, medications or lifestyle changes that improve mitochondrial function or reduce harmful fats might help prevent the inflammation that leads to complications.
Dr. Nikolajczyk and her team are hopeful that this new understanding could transform the way doctors treat type 2 diabetes. Instead of just focusing on blood sugar, treatments could become more well-rounded, addressing the root causes of inflammation. This could lead to better outcomes for millions of people around the world.
In conclusion, this groundbreaking study challenges the long-held belief that glucose is the main driver of inflammation in type 2 diabetes. By uncovering the role of mitochondria and fat derivatives, the University of Kentucky researchers are paving the way for new therapies that could improve the health and quality of life for those with diabetes.
This discovery is a reminder that science is always evolving, and understanding the deeper causes of disease can lead to better, more effective treatments.
