Treatment for Obesity

It is important to modify your diet and be involved in physical activities to lose excess weight and maintain the weight loss over the long term.

  • Medications

    Most available weight-loss medications are "appetite-suppressant" medications. Appetite-suppressant medications promote weight loss by decreasing appetite or increasing the feeling of being full. These medications decrease appetite by increasing serotonin or catecholamine - two brain chemicals that affect mood and appetite. Prescription weight-loss medications should be used only when there is increased medical risk because of your weight and not for cosmetic reasons.
