Weight Loss Treatment
If you are searching for medical weight loss in Alpharetta, Vigor Wellness Space offers something most commercial programs don’t: a nurse practitioner who personally evaluates, doses, and monitors every patient from the first visit through the entire course of treatment.
The need is real in Georgia. Adult obesity prevalence in Georgia was 35.4% as of the CDC’s most recent Behavioral Risk Factor Surveillance System data, ranking the state 19th nationally. Diabetes affects an estimated 11.4% of Georgia adults according to the Georgia Department of Public Health, with tens of thousands more living with the condition undiagnosed. GLP-1 therapies were originally developed to treat type 2 diabetes and are now the most clinically validated medical weight loss tool available, regulating appetite and blood sugar through the same hormonal pathway. We also offer GLP-1 weight loss in Johns Creek for patients closer to our clinic.

How GLP-1 therapy works
GLP-1 medications work by mimicking a hormone your body already produces to regulate appetite and digestion. They suppress hunger, slow gastric emptying, and improve insulin sensitivity, which together produce sustained, gradual weight loss rather than rapid, hard-to-maintain results.
Treatment starts with a comprehensive initial assessment covering your health history, current medications, and weight-related goals. From there, we build a personalized dosing plan, starting at a low dose and adjusting over time based on your response and any side effects. Ongoing follow-up appointments track your progress and let us fine-tune your plan as you go.
