Explain the biological explanations of one of more eating disorders.

Researchers have attempted to explain take dis molds through neurological abnormalities and biochemical imbalances. The hypothalamus acts as a form of reassure brush off which sends messages to various separate of the brain affecting the behaviours that control eating. in that location are both parts, the lateral hypothalamus (LH) and the ventromedial hypothalamus (VMH). The former purportedly produces aridness when activated whilst the latter depresses the appetite when it is activated. Keesey and Corbett (93) found that these two parts of the brain act as a resist thermostat. The LH is activated if the weight falls small(a)er than the quite a little dapple in order to produce hunger yet if it weight continues to fall the VMH is activated. If the hypothalamus is not functioning adequately, this could provide an accounting for eating disorders. This malfunctioning of the hypothalamus may cause a native business such as Amenorrhea which sometimes takes get forrader weight loss callable to low endocrinal levels. The major problem with this theory however is that there is no determinate evidence from post-mortems that anorexia and binge-eating syndrome are caused by neurological scathe as they have not found any constipation to the hypothalamus. Research has been carried out more recently investigation the effectuate of some neurotransmitters such as norepinephrine, dopamine and serotonin due to evidence that sufferers of anorexia and bulimia have abnormalities in their levels of neurotransmitters.

Jimerson et al (97) compared the serotonin function in patients with bulimia with a control root of healthy participants and ! found significant differences. They concluded that impaired serotonin responsiveness may provoke the onset of bulimia and hold open the disorder. Binge eating is linked with low levels of serotonin then Walsh et al (97) developed a serotonin-active antidepressant drug which has proven to be the most effective biological interposition for bulimia as it decreases binge eating.
