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
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.
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
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
- Full conversion of gastric bypass to BPD-DS
- Physiologic conversion of gastric bypass to BPD
- Band over bypass
- Fobi pouch revisions
- Band removal
- DS reversal (formal and/or physiologic)
- SADI conversion to true DS
- OAGB conversions
- Surgery for unexplained chronic pain after bariatric surgery
Additional options
Explore OAGB, SADI-S, endoscopic therapies, bands and omentectomy.
These are not the default menu. They are reasonable alternatives with their own indications:
- One-anastomosis gastric bypass (OAGB)
- SADI
- Endoscopic therapies
- Adjustable gastric band (AGB), mainly for patients who already have a band or a specific indication
- Metabolic omentectomy: evidence and limitations
