The gastric balloon is a temporary, non-surgical weight-loss option in which a balloon is placed in the stomach and inflated. It reduces stomach capacity, helping patients feel full on smaller meals. This procedure is ideal for those who need assistance with weight loss but are not ready for permanent bariatric surgery.

RNY reversal is the process of undoing the Roux-en-Y gastric bypass. Although rare, reversals are sometimes necessary due to complications such as malnutrition, severe dumping syndrome, or other medical issues.

Gastric banding is a type of bariatric surgery in which an adjustable band is placed around the upper part of the stomach to create a small pouch that limits food intake. It is one of the least invasive forms of weight-loss surgery but has fallen out of favor due to its lower success rates compared to other procedures like the sleeve gastrectomy or Roux-en-Y bypass.

Weight lost refers to the reduction in body weight that is typically achieved through lifestyle changes, medications, or bariatric surgeries like the RNY or gastric band. Weight loss, particularly significant or rapid weight loss, can have dramatic positive effects on a person's overall health, reducing the risk of heart disease, diabetes, and other obesity-related conditions.
