Pharmacotherapy for obesity

 

Obesity is a serious, chronic, relapsing disease of energy regulation, with strong genetic and early-life environmental determinants.

Medications can be useful adjunct to lifestyle intervention in effecting and maintaining clinically significant weight loss in those with BMI >30, or 27-30 and obesity-related complications.

*Check BMI here.

Safety and efficacy should be monitored closely on commencement and the medication should be discontinued if there are safety or tolerability issues, or if <5% weight loss is observed after 3-4 months

For the majority of patients, following the exemplary diet and exercise recommendation provide only modest or no weight loss and difficulty to sustain.
