Is it an illness or simply a lack of willpower? Should it be a deciding factor in the treatment of patients in the NHS?
It is a fact that the way we feel can have consequences on the amount of food we eat. Alimentation is the first thing that changes when people start having psychological problems, so a variation of the "regular" diet can be a symptom of something more.
We should treat obesity, bulimia and anorexia in the same way because they're all psychological diseases that have concrete effects on alimentation.
When we talk about obesity, we should ask ourselves "Why do these people eat so much?", instead of judging people who are evidently fat. There must be a reason if someone starts overeating: maybe he doesn't feel satisfied with himself and his own life. The point is: why is he so disappointed? This is the question we may start from when we want to understand an obese person.
Obesity can be the consequence of a psychological trauma - the loss of someone important, sex abuse or a traumatic event in the past, for example. It is known that people who have been sexually abused may develop alimentary disorders (probably because the want to "punish" their own body and turn it unattractive).
A possible way to treat obesity is psychotherapy. Talking with a therapist, the obese person can understand when and why the problem started. In this way, the patient and the psychologist may find a solution.
Of course, a healthy lifestyle (healthy alimentation and physical activity) is very important, but only after the true trauma has been recognised.
Surgery is not the solution: if fat people don't understand the origins of their problem, surgery is useless (after the operation, they will continue to eat a lot).
The NHS (National Health Service) should not punish obese people: it is a national service and should offer everyone the same opportunities. Fat people deserve the same attention as thin people. Fat people pay taxes exactly like the other citizens, so they have the right to be treated. But, in my own opinion, before being operated (I'm talking about gastric surgery) obese patients should be given the possibility to speak with a psychotherapist and find the motivation to lose weight.
To sum up, obesity is an illness that is becoming more and more dangerous in our society. Punishments are not the cure; talking with someone is the best way to get rid of obesity.
