The relationship between mood and glucose levels 

Changes in glucose levels can greatly impact how you feel physically and emotionally. The brain uses a lot of glucose to function, so it makes sense that glucose levels can affect how we feel mentally and emotionally.  

Although everyone is different, low glucose (hypoglycaemia) can cause anxiety, irritability, and confusion, and high glucose (hyperglycaemia) can cause tiredness, low mood, and anger. Glucose levels that remain high over a long period of time can put the person at increased risk of depression, which can then make it harder for them to make changes to reduce glucose levels – so the cycle can continue.  


What if my thoughts and feelings about diabetes really start to affect my diabetes self-care? 

Living with an unpredictable health condition like diabetes can be extremely challenging, so it is understandable for people to experience some difficult thoughts, feelings, and responses (behaviours) like those outlined above. However, sometimes people can feel very overwhelmed by living with diabetes and the burden of self-care, they may experience something called diabetes distress, which may lead to a period of “diabetes burnout”. Evidence from research shows that 1 in 4 people with Type 1 diabetes has a high level of diabetes distress at any one time, and this is likely to be having a negative impact on how they manage their diabetes.
