Obesity is increasingly recognized not merely as a lifestyle issue, but as a chronic, relapsing disease requiring sustained clinical management. Despite rising prevalence and cardiometabolic risks, pharmacologic treatment remains underutilized. While lifestyle interventions are foundational, maintaining weight loss over time through lifestyle changes alone is often challenging. High-intensity behavioral interventions may yield 5–8% total body weight loss, but this often plateaus or regresses by 12 months.
US clinical guidelines recommend anti-obesity medications when BMI is ≥30 kg/m², or ≥27 kg/m² with comorbidities. However, fewer than 2% of eligible patients receive prescriptions. Barriers such as stigma, limited access to specialists, and coverage restrictions may contribute to low treatment rates. GLP-1 receptor agonists, among newer therapies, address the biological drivers of obesity and have demonstrated significant weight loss (>10–20%) and cardiovascular risk reduction in clinical trials.
With an expanding range of therapeutic options, the focus is shifting to identifying the right patients and aligning treatment with their individual clinical needs and goals. Long-term success often depends not just on initiating therapy, but on sustaining it over time.
What clinical factors guide your decision to initiate pharmacologic therapy for obesity, and how do you approach patient selection, support long-term adherence, and identify those most likely to achieve sustained outcomes?

Peggy Cyr4dI prescribe a lot of weight loss medication. The major barrier is insurance coverage of GLP-1 Agonists. I surprisingly find patients willing to try a once weekly injection. Also once patients see how well these meds work compliance is not an issue at all. -
Anonymous User1moIf the patient is motivated and willing to participate in treatment, if they can afford it or if covered by insurance, follow up appointments for long term adherence and guidance on lifestyle management. -
DAVID DI CESAR2moThere is no stigma. The biggest problem is getting insurance coverage. This should improve over time and in the future -
Leon Ronen3moFirst, I screen for contraindications like MEN, Thyroid Cancer, Pancreatitis, Gastroparesis, significant GI issues. If cleared then I will offer to anyone with BMI above 30 that desires weight loss. I stress it causes reduction in appetite but will not be as effective in person who stress eat or eat as a result of boredom. It can cause slight muscle loss and imperative to incorporate eating pattern changes as well as exercise to provide long term benefits and maintain achieved weight loss. I offer referral for nutritional counselling. -
Muhammad Nawaz3moIt is a great time to practice Bariatric Medicine thanks to the wonderful GLP-1 and related meds and the sophistication and safety of the Bariatric surgery , GLP-1s have gone beyond use in obesity and with their positive outcomes in CVD are being used in CVD , CKD and OSA , The decision to start these meds is based on how prepared and congitive the pt is to be started on these meds and is sycnh with the diet and exercise programa which is an essentional component to manage obesity on these meds once pt is in synch with this concept counsel them these meds promote early satiety rahter than priamrily supress the appetite and that is how they will lose weight counsell them about side effects and make sure there are no contraindications so this is how the pt is selected who would benefit from these meds and have real time expecations ofcourse insurance coverage and affordaility is kept in mind as well Pt once started have a follow up visit in 3-4 weeks for the dose titration and review and motivate them for continued diet and exercise program along with the compliance of the medicine So this is how long term adherence is ensured with continous motivations and regular follow up and discuss the results achieved and future goals -
Christopher Case3moCost and formulary is the main driver. Next is patients willingness to try a medication and possibly an injection. No other clinical factor generally shows whom be successful. Compliance is good but hampered by costs mainly. Only a few stop for nauseu and some these are not effective enought to reduce food noice to continue. -
Irina Robinson3mofamily history of obesity, previous trials of OTC, commercial weight loss programs or Rx meds, generally offer 100% of my pts at the initial visit who meet the criteria and request the prescription, about 33% of pts decline therapy stating the exact reasons that I describes in the question -
Jorge Osorio4moExplaining to the patient the obesity is a chronic disease, needs change in dietary habits, exercise and may need medication to support weight loss, also explaining the bariatric surgery option. When prescribing Glp-1 ra I explained the cardiovascular benefit, renal, joints, sleep apnea benefit.
