Mental health has a direct and bidirectional impact on people with diabetes. Psychological stress such as loneliness, anxiety and depression can raise blood sugar levels through hormonal effects, while also reducing motivation for self-care.
According to Healthline, estimates suggest that about 10% of patients experience depression and 25% experience mood fluctuations, negatively affecting adherence to treatment and glucose monitoring.
Diabetes and loneliness
Loneliness is closely linked to an increased risk of developing type 2 diabetes and to worsening health outcomes in those who already have the condition.
Chronic loneliness triggers stress hormones such as cortisol, increasing insulin resistance and raising blood sugar levels. It may also lead to neglect of self-care and unhealthy lifestyle habits.
Relationship between loneliness and diabetes:
Studies suggest loneliness and social isolation may increase the risk of developing type 2 diabetes by up to 32%.
Higher levels of loneliness have been observed among patients with chronic complications such as retinopathy or neuropathy.
Loneliness activates the body’s stress response on a daily basis, increasing cortisol and disrupting blood sugar regulation.
Studies indicate loneliness may raise the risk of heart disease in people with diabetes by up to 26%.
People experiencing loneliness are more likely to be physically inactive, smoke, and follow unhealthy diets.
Diabetes, anxiety and depression
Anxiety and depression have a two-way relationship with diabetes. Depression increases the risk of developing type 2 diabetes, and people with diabetes are more likely to experience depression, which negatively affects blood sugar control.
Relationship between diabetes, depression and anxiety:
People with diabetes are two to three times more likely to develop depression.
Depression risk increases in both type 1 and type 2 diabetes, reducing quality of life.
Depression leads to fatigue and low motivation for self-care, raising blood sugar levels.
The daily burden of managing diabetes may lead to “diabetes distress,” a mix of frustration and anxiety.
Managing stress to control diabetes
Psychological support: speaking with a doctor or mental health specialist is essential.
Integrated care: combining mental health care with diabetes management.
Lifestyle measures: regular exercise, healthy eating, and adherence to medication schedules.
Physical activity: helps reduce stress hormones and improve insulin sensitivity.
Relaxation techniques: yoga, meditation and deep breathing.
Adequate sleep: sleep deprivation increases cortisol levels.
Continuous monitoring: use of continuous glucose monitoring devices.
