WELCOME TO DIABETES STRONG
Diabetes Strong was established in 2015 as a personal blog about Christel’s experiences as a fitness enthusiast living with type one diabetes.
Christel struggled to find easily accessible information about exercise and healthy nutrition with diabetes online, so she decided to create a website where she could share her own advice and invite experts from the diabetes community to contribute.
Diabetes Strong quickly grew into one of the largest websites about health and diabetes and was re-launched in 2017 as a diabetes portal with expert contributors from all over the world.
The goal of Diabetes Strong is to provide a platform where people living with (any type) of diabetes can find all the information they need to live healthy and active lives.
The information on Diabetes Strong always takes a positive approach to diabetes and follows Christel’s motto that “There is nothing you can’t do with diabetes.”
