Medical Weight Loss Corpus Christi operates under the clinical direction of Dr. Marianne Hazelitt, D.O., A.B.I.M., a board-certified internist who applies functional medicine principles to obesity treatment and chronic disease reversal in Corpus Christi, Texas. Dr. Hazelitt's approach integrates pharmaceutical interventions with metabolic optimization, addressing the root causes of weight gain rather than treating symptoms in isolation. The clinic serves patients throughout the Coastal Bend region who require medical supervision for complex weight management cases, particularly those with comorbid conditions such as type 2 diabetes, hypertension, and metabolic syndrome.
The clinic's pharmaceutical protocol centers on two glucagon-like peptide-1 (GLP-1) receptor agonists: tirzepatide and semaglutide. Tirzepatide functions as a dual GIP/GLP-1 receptor agonist, activating both glucose-dependent insulinotropic polypeptide and GLP-1 pathways to regulate appetite, slow gastric emptying, and improve insulin sensitivity. Semaglutide operates through selective GLP-1 receptor activation with similar metabolic effects. Dr. Hazelitt determines peptide selection and dosing based on individual patient factors including baseline A1C levels, cardiovascular risk profile, gastrointestinal tolerance, and weight loss goals. Both medications require subcutaneous injection on a weekly schedule, with titration protocols adjusted according to patient response and side effect profile. The clinic monitors patients for common adverse effects including nausea, constipation, and gallbladder complications, while tracking metabolic markers through regular laboratory assessment.
Dr. Hazelitt's internal medicine training provides the clinical foundation for managing patients with multiple chronic conditions who require coordinated care during weight loss interventions. Her functional medicine framework examines contributing factors such as insulin resistance, inflammatory markers, thyroid function, cortisol dysregulation, and nutrient deficiencies that may impede weight loss or contribute to metabolic disease. Patients undergo comprehensive evaluation including metabolic panel, lipid profile, hemoglobin A1C, thyroid function tests, and body composition analysis before initiating GLP-1 therapy. This diagnostic approach allows Dr. Hazelitt to identify contraindications, optimize concurrent medications, and establish baseline metrics for tracking clinical outcomes throughout treatment.
In-person consultations at the Corpus Christi clinic include initial evaluation appointments lasting 60-90 minutes, during which Dr. Hazelitt reviews medical history, current medications, previous weight loss attempts, and treatment goals. Follow-up visits occur at intervals determined by medication titration schedule and patient stability, typically every 4-6 weeks during the initial phase. These appointments include weight and vital sign measurement, review of food intake patterns, assessment of medication tolerance, and adjustment of dosing protocols. The clinic provides injection technique training for patients self-administering peptides at home, along with guidance on managing common side effects such as reduced appetite and altered taste perception. Patients receive structured support for the dietary modifications necessary to maximize GLP-1 efficacy while maintaining adequate protein intake and nutritional balance during caloric restriction.
Medical Weight Loss Corpus Christi differentiates itself through Dr. Hazelitt's emphasis on chronic disease reversal rather than weight reduction alone. Treatment plans target specific metabolic endpoints such as hemoglobin A1C reduction, blood pressure normalization, and lipid profile improvement, with weight loss serving as both an outcome and a mechanism for achieving these clinical goals. The clinic's functional medicine orientation means patients receive evaluation and treatment for underlying factors that perpetuate obesity, including hormonal imbalances, chronic inflammation, and metabolic dysfunction. This comprehensive approach proves particularly relevant for Corpus Christi residents facing high regional rates of obesity and diabetes, providing medical-grade intervention for patients who have not achieved sustainable results through diet and exercise modifications alone.
