Pharmacological Treatment²
Pharmacological treatment should be considered as part of a comprehensive strategy of the obesity disease management (diet and physical activity are prerequisites).
Individuals that could be eligible to receive a drug therapy are those with a BMI ≥ 30 kg/m2 or a BMI ≥ 27 kg/m2 with an obesity-related disease (e.g. hypertension, type 2 diabetes mellitus, sleep apnea)
The check point of 3 months is important, meaning that, if an individual, under drug therapy, has not achieved a weight reduction of >5%, within this period, then there is no advantage of continuing the pharmacotherapy and treatment should be discontinued. Especially, if the individual has type 2 diabetes, then the >3% weight loss is the target so as to evaluate if she/he is responding to the treatment or not.
