Continuing from the previous post on exploring the cause of obesity, we will be exploring how one’s poor mental health could also be an important factor that contributes to the development of obesity. Anxiety and depression are the most common mental diseases the about 25% of the world’s population would experience at least once in a lifetime in which the number of teenagers suffering from such diseases significantly increased over the last 30 years. While lack of motivation to get out of bed is a more common symptom associated with anxiety and depression, overeating, is one of the less known symptoms of anxiety and depression. There is a very popular on TED that explains what depression is and has indicated that people with symptoms of depression are often reluctant to receive treatment and those who eventually received treatments have often been struggling with the problem for about 10 years. This is particularly difficult for adolescents to be aware their change in eating and physical behaviour as they would most likely think that the change is linked to puberty. I believe that given the forever increasing number of people getting mental illnesses, it is of utmost importance that the government and various NGOs, such as Beyond blue, to make sure adolescents have access of relevant information and services more efficiently.
