Clinical Definition

Common bariatric procedures:

  • Gastric Bypass: Roux-en-Y gastric bypass surgery
  • Sleeve Gastrectomy: Removal of portion of stomach
  • Gastric Banding: Adjustable gastric band placement
  • Duodenal Switch: Combination restrictive and malabsorptive procedure
  • Gastric Balloon: Temporary intragastric balloon

Bariatric surgery can lead to dramatic improvement in OSA severity, with many patients experiencing complete resolution.

Etymology & History

Bariatric surgery evolved from early gastric procedures in the 1950s, with modern techniques developing in recent decades as obesity became recognized as a major health issue.

Reference Values & Interpretation

Normal Values

Bariatric surgery success includes substantial weight loss (50-80% of excess weight) and significant improvement or resolution of OSA.

Abnormal Values

Bariatric surgery complications can include surgical risks, nutritional deficiencies, dumping syndrome, and the need for lifelong follow-up.

How It's Measured

Bariatric surgery outcomes are assessed through weight loss, improvement in comorbidities including OSA, and quality of life measures.

Role in Diagnosis

Bariatric surgery is indicated for severely obese patients with OSA who meet established criteria for weight loss surgery.

Role in Treatment

Bariatric surgery can provide dramatic and sustained improvement in OSA, often allowing patients to reduce or discontinue CPAP therapy.
