Upper gastrointestinal series – Definition

This is a series of x-rays of the esophagus, stomach, and duodenum (the first part of the small intestine). Together, the esophagus, stomach, and duodenum are called the upper gastrointestinal (GI) tract, or upper digestive system. The x-rays are taken during and after drinking a chemical called barium. The barium solution is a thick, white, chalky, milkshake-like liquid. It coats the inside lining of your GI tract. This makes the GI tract show up better on the x-ray.

Roux-en-Y gastric bypass – open surgery – Definition

Roux-en-Y gastric bypass is a surgery for obesity. It changes the stomach and small intestine to cause weight loss by:

  • Restricting food intake — creates a small pouch to serve as the stomach, so you cannot eat as much
  • Making the body unable to absorb as many calories from the food — bypasses the first part of the small intestine, where many of the calories from food are usually absorbed.
