Obesity

Obesity sychological Status Dysphoric mood state and weight status are frequently related (31). The data analysis from the National Health Epidemiological follow-up study to the first National Health and Nutrition Survey revealed that depression played a substantial role in the patterns of weight change in US adults (34). Persons who gain weight with one episode of depression tend to gain weight with the next, just as persons who tend to lose weight with depression have a similar response with the next occurrence of depression (35). The use of medications to modify psychiatric dysfunction with resultant weight modification is discussed above (31). Studies have indicated that brain serotonin is critically involved in controlling mood, and many patients learn they can transiently reduce depressive symptoms by eating. This is frequently seen in seasonal affective disorder, premenstrual syndrome, and nicotine withdrawal (36). Genetics Advancements in the field of genetics and obesity may lay the groundwork for the development of effective pharmacotherapy. Evidence for a strong genetic contribution of human obesity comes from a variety of sources. Twin and familial aggregation studies suggest that genetic factors account for 60% to 80% of the predisposition to obesity (16-19).
