Sugar: A Potential Cause of Depression

Depression is one of the common mental disorder that could lead to substantial impairments in a person’s ability to take care of everyday responsibilities. According to research millions of adults in the United States are living with depression and there is a significant increase in the total number of diagnosed cases of depression each year.

Depression is defined as a chronic brain disorder which is characterized by depressed mood, loss of interest, problems with sleep, lack of energy, poor appetite and problems with concentration. In other words, depression is a medical condition that can have a significant impact on the quality of life of an individual.

The symptoms and signs of depression are not only characterized by negative thoughts and depressed mood, but it is also characterized by specific changes in the functions of the body such as sleeping pattern, weight management, sexual impairments, and many more problems. These functional changes are often regarded as neurovegetative signs. Many changes in the brain cause changes in the functionality of various health problems.

Evidence suggests that high sugar consumption is one of the risk factors of depression. It is very well known that excessive consumption of sugar could lead to various health problems. Higher consumption of sugar may accelerate and leads to the development of some chronic diseases, including depression. Sugar causes an impairment in some of the important glands and organs that are important for the normal functioning in the human body.

Multiple studies have been conducted to investigate the role of sugar in the development of mental disorders. It has been found that consumption of sugar, especially when consumed in excessive amount could result in changes in the brain neurochemistry. Consumption of sugar has been found to be linked to psychological problems in a variety of ways. Psychological problems such as stress, major depression, psychological distress, and suicidal ideation.

According to one of the studies that were conducted in six countries, it was clear that there is a strong correlation between the consumption of sugar and the annual rate of depression. The possible relationship between depression and consumption of sugar is primarily due to the correlation between the consumption of sugar, endorphins, and oxidative stress.


Excessive intake of sugar leads to an increase in the level of endorphins and this abnormality in the levels of endorphins are known to play a role in the development of depression in people. Oxidative stress is also known to contribute to depression in various different mechanisms and sugar is one of the causes of increased oxidative stress in individuals.

How is depression linked with diabetes mellitus?

Diabetes mellitus is a chronic disorder which is characterized by hyperglycemia or high glucose level in the blood. It is one of the most common metabolic diseases affecting millions of individuals throughout the world. Glucose is a sugar that a body uses in the form of energy but when the glucose level increases, it affects the body in various ways. Hyperglycemia can results from insufficient production of insulin, inefficient use of insulin by the body or both.

Evidence suggests that there is a strong link between diabetes and the development of depression. It has been observed that most of the patients who suffer from depression have a high glucose level in the blood and many are also suffering from diabetes mellitus.

Diabetes mellitus is considered to be a serious risk factor for depression. The high sugar level in the blood can worsen depression which in turn make it difficult to manage diabetes effectively. It is believed that people having diabetes mellitus are twice more likely to suffer from depression as compared to those who do not have any chronic disease.

There are various mechanisms that explain how diabetes mellitus can result in the occurrence of depression. The two major factors that are responsible for the development of depression is stress and genes. The two primary reasons that make patients having diabetes more likely to suffer from depression include:

Management of diabetes in the right way is one of the common stress in the lives of diabetic patients. It can act as a burdensome to ensure that the right steps are being taken to manage sugar level in the blood. In case of complications of diabetes, the risk of depression increases. Complications of diabetes are associated with increased tension as complications can significantly impair quality of life of an individual.

Sometimes diabetes mellitus is also associated with some other medical conditions that affect the brain and could lead to the development of the symptoms of depression. Also, there are certain medicines that can also contribute to depression. High glucose level is also associated with impaired sleep pattern which in turn is one of the early symptoms of depression.

Also, it is believed that fluctuations in the level of glucose in the blood could influence the functioning of the brain. Depression is a brain disorder and when the functioning of the brain is influenced, the risk of depression increases. It can have an effect on all the aspects of a cognitive system.
