A direct link has been theorized between diabetes and anger leading to problems with the regulation of sugar levels passing through the blood of the body. Anger is also a common feeling felt by individuals diagnosed with the medical condition that is related to the stress that often effects those with diabetes. Direct scientific research has failed to provide a direct link between stress-related conditions, such as anger leading to diabetes.

Hormones within the body that are used to regulate the levels of glucose within the blood are the same as those used to regulate stress levels leading to feelings including anger and depression. This is particularly true in the case of type 2 diabetes where the body fails to transport insulin produced in the pancreas around the body despite the correct amount of insulin being produced for transporting glucose from the blood into the cells of the body. During times of elevated anger levels, the hormones affecting blood sugar levels become overstimulated and can increase or decrease production of insulin and the transportation of the chemical around the body.

Diabetes and anger treatments have been developed to use stress and anger management techniques to maintain the balance of insulin production levels and the movement of glucose around the body. Included in the types of treatments used in the management of anger levels for diabetes control are muscle relaxation and behavioral therapies directed to eliminating negative thoughts and emotions from the mind and body. The treatments recommended are intended to be used as supplemental therapies in conjunction with traditional diabetes treatments including insulin supplements.

Diagnosis of a person with diabetes often leads to periods of anger and depression directed towards the medical condition and the perceived unfairness of the diagnosis. During periods of anger, a diabetes patient often finds difficulty in maintaining a diet or exercise program created to help him or her to deal with a diabetes diagnosis. Diabetes and anger are also linked to problems involving disrupted medicine intake patterns that can lead to problems with maintaining the correct balance of blood sugar in the human body.

A study completed by Kuwait University found that the instances of type A diabetes and anger-related behaviors was higher in diabetes patients than in non-diabetes patients. Anger-related behavior was also found to be higher in patients with type 1 than type 2 diabetes. Links have been difficult to prove between the use of behavioral therapies and the maintaining of blood sugar levels when used in tandem with traditional diabetes treatments.
