Summary
This summary is machine-generated.Metabolic and bariatric surgery (MBS) is safe and effective for vegetarians and vegans, showing significant weight loss. Nutritional deficiencies were manageable, indicating MBS is a viable option for this growing population.
Area Of Science
- Bariatric Surgery
- Nutritional Science
- Vegetarianism & Veganism
Background
- Vegetarianism and veganism are increasing globally.
- Limited data exists on metabolic and bariatric surgery (MBS) outcomes for vegetarians/vegans.
Purpose Of The Study
- To evaluate the outcomes of metabolic and bariatric surgery (MBS) in patients adhering to a vegetarian or vegan diet.
Main Methods
- Retrospective analysis of prospectively maintained data from a single bariatric surgeon.
- Inclusion of all vegetarian or vegan patients undergoing MBS.
Main Results
- Eleven patients (10 female, mean age 40.8 years, BMI 43.5 kg/m²) underwent MBS.
- Common procedures included one anastomosis gastric bypass (OAGB).
- Mean BMI decreased to 28.2 kg/m² with 35.3% total weight loss at 17-month follow-up; nutritional deficiencies (Vitamin D, Iron) were observed but manageable.
Conclusions
- Metabolic and bariatric surgery (MBS) appears safe and effective for vegetarian/vegan patients.
- Nutritional deficiencies can occur but are acceptable and manageable.
- Further large-scale studies are needed to confirm these findings.

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Vagotomy: This procedure aims to reduce gastric acid secretion by cutting a portion of the vagus nerve. While effective, its frequency has declined due to the availability of effective acid-suppressing medications. It may be performed with or...
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:
Strictureplasty
Proctocolectomy or total colectomy with ileostomy
Restorative proctocolectomy with Ileal pouch-anal anastomosis
