Renaissance Medical by Dr. Yixiu Zheng

Renaissance Medical, founded in 2011 by Dr. Yixiu Zheng, operates as a comprehensive internal medicine and functional wellness practice in New York, NY, integrating primary care with advanced metabolic and aesthetic interventions. Dr. Zheng holds board certifications in Internal Medicine, Obesity Medicine, Aesthetic Medicine, and Anti-Aging/Regenerative Medicine (ABAARM), along with a Fellowship in Anti-Aging, Metabolic and Functional Medicine (FAAMM), positioning the clinic to address complex metabolic disorders, hormonal imbalances, and body composition challenges through evidence-based protocols. The practice serves patients seeking both routine primary care and specialized interventions for weight management, hormone optimization, and age-related health concerns within a single clinical setting in New York City.

The clinic's peptide-based weight loss programs center on Semaglutide and Tirzepatide, two GLP-1 receptor agonists that modulate appetite regulation and insulin sensitivity. Semaglutide therapy at Renaissance Medical is prescribed for patients with obesity or overweight status accompanied by metabolic comorbidities, delivered via weekly subcutaneous injection with dosing titrated based on individual tolerance and weight loss trajectory. Tirzepatide, a dual GIP/GLP-1 receptor agonist, is offered for patients requiring more robust glycemic control or those who have plateaued on single-agonist therapy, with protocols adjusted to minimize gastrointestinal side effects while maximizing fat mass reduction. Both peptide regimens are integrated with nutritional counseling, metabolic panel monitoring, and body composition analysis to ensure safe, sustainable outcomes. The practice also addresses hormone optimization through bioidentical hormone replacement and thyroid management, particularly for patients experiencing metabolic slowdown, fatigue, or difficulty losing weight despite dietary adherence.

Dr. Zheng's multi-specialty training allows Renaissance Medical to evaluate weight loss candidates through a functional medicine lens, identifying underlying contributors such as insulin resistance, thyroid dysfunction, cortisol dysregulation, or nutrient deficiencies that may impede progress. Patients undergo comprehensive lab work including fasting insulin, hemoglobin A1c, lipid panels, thyroid function tests, and sex hormone assessments before initiating peptide therapy, ensuring contraindications are identified and concurrent metabolic issues are addressed. The clinic's approach to obesity medicine extends beyond pharmacotherapy to include lifestyle modification strategies, continuous glucose monitoring interpretation for select patients, and coordination with aesthetic treatments such as body contouring or skin tightening procedures as patients achieve significant weight reduction. This integrated model is particularly relevant for New York patients seeking a single provider capable of managing both medical and aesthetic dimensions of weight loss.

In-person consultations at Renaissance Medical's New York office allow Dr. Zheng to perform physical examinations, review imaging or lab results in real time, and adjust treatment plans based on patient-reported outcomes and objective measures such as blood pressure, waist circumference, and body mass index. The practice functions as a primary care home for many patients, enabling longitudinal management of chronic conditions like hypertension, hyperlipidemia, and prediabetes alongside peptide therapy, which streamlines care coordination and reduces the need for multiple specialists. Patients typically begin with an initial consultation lasting 45-60 minutes, during which medical history, weight loss goals, previous diet attempts, and current medications are reviewed in detail. Follow-up visits occur every 4-6 weeks during the active weight loss phase, with ongoing monitoring of kidney function, heart rate, and gallbladder health given the known side effect profile of GLP-1 agonists.

Renaissance Medical's 4.8-star rating across 70 Google reviews reflects patient satisfaction with Dr. Zheng's thoroughness, accessibility as a primary care physician, and willingness to incorporate emerging treatments into practice. The clinic's location in New York, NY, serves patients across Manhattan and surrounding boroughs who prioritize continuity of care and prefer a physician trained in both conventional internal medicine and functional approaches to metabolic health. With over a decade of clinical experience since its 2011 founding, Renaissance Medical has developed protocols that balance aggressive weight loss interventions with patient safety, making it a resource for individuals who have struggled with traditional diet-and-exercise programs or who require medical management of obesity-related comorbidities alongside aesthetic enhancement.
