Offices of Dr. Elariny

Bariatric surgery chosen with you, not for you

Sleeve, bypass, duodenal switch, and revision each have their own strengths, limits, and selection criteria. The surgeon’s job is to explain those clearly. Your job is to show that you understand them before you consent.

Advanced Bariatric Services, LLC

Weight-loss and metabolic surgery with Dr. Hazem A. Elariny, MD, PhD, FACS. You will hear the real trade-offs of each operation — expected weight loss, vitamins, protein, side effects, and what “beating” a procedure looks like — then you name the operation that fits how you eat and live, and you explain why.

A dedicated first year of follow-up, labs, and direct access is part of how this practice supports patients after surgery. Learn about financial arrangements and concierge access.

Core operations

Sleeve gastrectomy diagram

Sleeve gastrectomy

A smaller stomach that changes meal capacity and hunger signaling. Sleeve and banded sleeve have different eating experiences; reflux and eating patterns matter in selection.

Roux-en-Y gastric bypass diagram

Gastric bypass

A small stomach pouch connected to a Roux limb. Reflux, sweet intake, dumping tolerance and long-term nutritional needs are part of the discussion.

Duodenal switch diagram

Duodenal switch

Sleeve plus intestinal bypass, with substantial metabolic effects and a greater nutritional burden. Protein, supplements, bowel effects and lifelong monitoring matter.

Revisions

Second operations are planned from anatomy and physiology, not from the popularity of a conversion. See the list below.

Revisions we perform
