Weight Loss &
Bariatric Surgery

Dr. Pakula is an ASMBS member who performs all bariatric procedures using advanced robotic and minimally invasive techniques — a science-based approach that addresses both the mechanical and metabolic drivers of obesity.

Is Bariatric Surgery Right for You?

Bariatric surgery is a medically proven treatment for severe obesity and the health conditions it causes. According to the National Institutes of Health, surgical intervention is indicated when nonsurgical approaches have not produced lasting results and when excess weight is contributing to serious medical risk. Dr. Pakula performs all weight loss procedures using robotic technology and minimally invasive techniques, reducing recovery time and surgical risk.

Candidacy is evaluated on an individual basis. A thorough consultation with Dr. Pakula will assess your medical history, current health status, and weight loss goals to determine the most appropriate procedure for your situation.

Indicated without additional conditions
BMI 35+
With obesity-related medical conditions requiring treatment

Surgical Procedures Offered

Most Common
Gastric Sleeve

Approximately 80% of the stomach is removed, leaving a narrow sleeve-shaped tube. This restricts how much food can be eaten at one time and triggers hormonal changes that reduce hunger and support sustained weight loss.

Laparoscopic & Robotic
Gold Standard
Roux-en-Y Gastric Bypass

The stomach is divided to create a small pouch connected directly to the small intestine. Food bypasses most of the stomach and upper intestine, producing rapid weight loss through both restriction and significant metabolic changes.

Laparoscopic & Robotic
Complex Cases
Revision Surgery

For patients who have had a previous bariatric procedure that has not maintained results or produced complications. Revision surgery converts the existing anatomy to a different configuration to restore effective weight loss.

Specialized Expertise

Obesity-Related Conditions Addressed

Bariatric surgery does more than reduce body weight. It produces measurable metabolic changes that improve or fully resolve many of the health conditions associated with obesity. Patients frequently see significant improvements in the following conditions after surgery.

Type 2 Diabetes
High Blood Pressure
High Cholesterol
Obstructive Sleep Apnea
Acid Reflux & GERD
Joint Pain & Osteoarthritis
Fatty Liver Disease
Cardiovascular Disease Risk

A Robotic Approach to Bariatric Surgery

Dr. Pakula performs all bariatric procedures using robotic and laparoscopic techniques. The Da Vinci robotic platform provides superior visualization and instrument precision inside the abdominal cavity, which is particularly beneficial in bariatric cases where anatomy can be challenging due to excess tissue. Robotic assistance allows for more precise staple line creation, consistent tissue handling, and reduced risk of complications.

As a member of the American Society of Metabolic and Bariatric Surgery, Dr. Pakula stays current with the latest evidence on surgical technique, patient selection, and long-term outcomes. Her approach treats the whole patient — not just the number on a scale.
