Diabetes is a disease that prevents the body from producing or effectively using insulin, a hormone responsible for regulating blood sugar levels. Beyond causing physical complications, diabetes is also closely linked to mental health disorders, including depression.
Diabetes has been found to contribute to the development of mental health disorders, particularly among patients under the age of 40. This means that diabetes does not only lead to a series of physical health problems, but also affects psychological well-being.
Dr. Juliana Chan, Director of the Hong Kong Institute of Diabetes and Obesity at The Chinese University of Hong Kong, explained that it is still unclear which condition appears first—whether diabetes leads to depression or depression increases the risk of diabetes. However, there is strong evidence suggesting that both conditions may influence each other.
“Diabetes is a complex disease that requires more than medication alone—it requires continuous support and guidance. Diabetes places many demands on individuals, which means patients must be educated, empowered, and encouraged to commit to lifestyle changes while learning how to cope with the disease,” Dr. Chan explained.
Type 2 Diabetes and Its Health Risks
Type 2 diabetes is a condition caused by persistently high blood sugar levels. If left untreated, elevated blood sugar can lead to serious complications, including heart disease, kidney failure, infections, and vision problems.
The biggest risk factors for developing diabetes are obesity and a lack of physical activity.
Dr. Juliana Chan encourages people with diabetes to commit to long-term lifestyle changes and adopt healthier living habits. Diabetes patients are advised to:
- Consume a balanced and nutritious diet
- Engage in regular physical activity
- Avoid factors that may trigger stress
Diabetes at a Young Age: A Cause of Mental Disorders?
Recent research conducted in Hong Kong revealed that 37 percent of hospital admissions among diabetes patients under the age of 40 were caused by mental health disorders, including mood disorders, depression, bipolar disorder, hallucinations, and schizophrenia.
Why are diabetes patients under 40 more vulnerable to mental health disorders?
According to Dr. Juliana Chan, who led the study, the psychological burden of living with diabetes—especially at a young age—plays a major role. Diabetes is a chronic condition that is not easily cured, which can become a significant source of stress for younger patients.
“Being diagnosed at a young age, undergoing long-term treatment, poor health control, and suboptimal self-care all contribute to the increased risk of hospitalization among young diabetes patients,” Chan explained.
This highlights the importance of not only managing blood sugar levels, but also addressing the mental and emotional well-being of individuals living with diabetes, particularly those diagnosed at a young age.
