Specialties and Bariatric Care Approach
Bariatric treatment is selected according to the patient’s weight, medical history, previous procedures, health risks, and long-term goals. Evaluation may include laboratory testing, nutritional assessment, medication review, and screening for conditions associated with obesity.
Dr. Marvin offers both surgical and less invasive treatment choices. Endoscopic sleeve gastroplasty reduces the functional size of the stomach using an endoscope and internal sutures, without traditional abdominal incisions. Surgical options such as sleeve gastrectomy and gastric bypass make more extensive changes to the digestive system.
Patients should understand the expected benefits, limitations, risks, recovery requirements, and nutritional changes associated with each option. Continued follow-up is important for monitoring weight, nutrition, vitamin levels, medications, and obesity-related conditions.
