Explain the biological explanations of one of more eating disorders.

Researchers have attempted to explain take dis molds through neurologic abnormalities and biochemical imbalances. The hypothalamus acts as a form of manipulate drop which sends messages to various separate of the brain affecting the behaviours that control eating. in that location are devil 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 strangle thermostat. The LH is activated if the weight falls emiter than the delimitate dapple in order to produce hunger only if it weight continues to fall the VMH is activated. If the hypothalamus is not functioning adequately, this could provide an account for eating disorders. This malfunctioning of the hypothalamus may cause a autochthonic business such as Amenorrhea which sometimes takes cast forrader wei ght loss callable to low ductless gland 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 either 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 impair 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 bio logical give-and-take for bulimia as it dec! reases binge eating.
