Cortisol levels linked to type 2 diabetesTuesday, 14 July 2020
Researchers at Ohio State University have found a clear link between the stress hormone cortisol and higher blood glucose levels in people with type 2 diabetes.
The study published online in the journal Psychoneuroendocrinology.
“In healthy people, cortisol fluctuates naturally throughout the day, spiking in the morning and falling at night,” said Dr. Joshua J. Joseph, an endocrinologist, and researcher who led the study.
“But in participants with type 2 diabetes, cortisol profiles that were flatter throughout the day had higher glucose levels.”
Previous research has shown that stress and depression are two of the major causes of a flatter cortisol profile. These sustained levels of cortisol make it much more difficult to control blood glucose and manage the condition, which is why it is so important for those with type 2 diabetes to find ways to reduce stress.
“We have begun a new trial to examine if mindfulness practices can lower blood glucose in those with type 2 diabetes,” said Joseph.
“But this isn’t the only effective form of stress relief. It’s important to find something you enjoy and make it a part of your everyday routine.”
The relationship of cortisol with glucose levels was only observed in those with diabetes. However, Dr. Joseph and his team believe the stress hormone likely plays an important role in diabetes prevention and they continue to research the connection between cortisol and the development of diabetes and cardiovascular disease.
More than one million Australians live with type 2 diabetes, which means their bodies aren’t using insulin effectively. Some people can manage their blood glucose levels with healthy eating and exercise, while others may need medication or insulin to help manage it.
Most people with type 2 diabetes know the importance of exercising regularly, eating a healthy diet, and getting plenty of rest. But stress relief is a crucial and often forgotten component of diabetes management.
Whether it’s a yoga class, taking a walk, or reading a book, finding ways to lower your stress levels is important to everyone’s overall health, especially for those with type 2 diabetes.
