Bulimia and the Human Brain


Many studies have been conducted on the effects of bulimia on the human brain. In addition to this, there have been medical studies conducted on how the brain reacts as time progresses in the bulimic. It has been established that those that suffer from bulimia have distinct differences in their brains.

This is especially true when the focus is placed on the brain's ability to regulate the hormone that has a direct impact on the overall appetite of an individual, as well as their overall mood. Basically, this could indicate that there are many people that may have a natural susceptibility to developing an eating disorder - specifically bulimia.

The Health Checks

The study that brought about the opinion that bulimia could be a direct result of a genetic susceptibility involved a total of nine females that had successfully recovered from the eating disorder. These women all struggled with binges, purging the food that they ate from their systems, and all agreed that the image that they had of themselves were highly distorted. These women also agreed that while experiencing bulimia firsthand, they often experienced mood complications such as anxiety, high irritation levels, and moderate to severe depression.

A special type of scanning instrument was used to evaluate the brains of the women in the case study. This imaging device is referred to as a "PET" scan. PET stands for "Positron Emission Tomography". In addition to those involved in the study, another assortment of twelve females were brought into the case study.

These women did not suffer from an eating disorder in the past or at the time that they were scanned. The point was to compare the brains of the females that once suffered to the brains of those that have not experienced the eating disorder of bulimia.

The Results

Once the scanning health checks were conducted, the researchers and medical professionals on the team that was conducting the study were quite impressed with their findings. The females that had suffered from bulimia in their lifetime showed a marked reduction in the task of binding receptors to the various regions of the brain.

The chemical directly responsible for this particular task is serotonin. As the studies developed, there was another interesting fact noted. The ones that suffered from bulimia did not seem to experience the natural reduction in serotonin in the brain that is found to occur in all instances of the aging process.

This was particularly interesting as the subjects that never suffered from the eating disorder were found to have relatively healthy serotonin levels and the chemical seemed to be performing on task in those test subjects.

Serotonin

While it may seem particularly insignificant, serotonin is actually a very important chemical in the brain. It is directly responsible for regulating several different aspects of who we are as people. This includes the following:

• The mood

• The Appetite

• The Ability to Control Impulses

While many professionals will agree that the effect of serotonin in the studies could be a result of the malnutrition and other physical effects often associated with bulimia, the researchers on this particular study feel as if this could be a reason that the eating disorder starts in susceptible individuals.
