Obesity and Treatment
Both overweight and obesity can sometimes be managed and reduced using a dietary change -- a more balanced diet, including less calories while still giving the body all the essentials.
Changes in food intake usually need to be accompanied by increased physical activity in order to encourage weight loss and reduce some weight-related health risks (i.e. to the heart).
Sometimes, however, dietary changes and physical exercise are not enough: they either do not help or are impossible to implement for various reasons.
In extreme cases of obesity, doctors may recommend weight-loss pharmaceuticals or even surgery in order to remedy the situation.
In addition, they have been found to be safe enough for use by people with no special risk factors (i.e. if the medication has side effects, the side effects are less dangerous for the patient than obesity is).
Such drugs generally belong to two categories -- either they work on chemicals in the brain that give you the urge to eat or the desire to stop eating, or they affect the digestive system.
