Diabetes is a chronic disease that requires long-term management and is accompanied by emotional stress. Psychological difficulties arising from the need for persistent self-management and difficulties due to complications related to the illness also lead to depression. Such depression results in difficulty controlling HbA1C, diet, exercise and medication. Therefore, depression management for diabetic patients is needed. Mindfulness-Based Cognitive Therapy modifies negative thinking patterns through mindfulness meditation that trains individuals to pay attention to what is and to not intentionally judge situations. This helps to ease depression and prevent a return to negative feelings. Thus, Mindfulness-Based Cognitive Therapy could help with blood glucose management and the emotional stability of diabetic patients.
