In acute bleeding, blood loss can be from the fresh staple lines that were made during a gastric bypass or the sleeve gastrectomy, from inadvertent injury to the spleen, or injury to one of the many blood vessels located in and around the surgical area.  Bleeding from these various sources can usually be stopped but in extremely rare cases, as in an injury to the spleen, the spleen may have to be removed to stop the bleeding.  In the extremely rare event of having to remove the spleen, a person can live without a spleen but will have to receive a vaccine after the spleen is removed.

The second type of bleed that can happen after Roux En Y Gastric Bypass or a Sleeve is a GI Bleed:  A GI bleed (gastrointestinal bleed) is when bleeding occurs anywhere along the GI tract and usually presents with vomiting blood or blood in the stool.  A GI bleed is another one of the uncommon Roux En Y Gastric Bypass Surgery and Sleeve Gastrectomy complications.  Gastrointestinal bleeding in patients who have undergone Roux En Y Gastric Bypass or Sleeve Gastrectomy may occur in the esophagus, gastric pouch, new Sleeve shaped stomach, the Roux limb just distal to the anastomosis, the remainder of the small intestine or even in the colon or rectum.  The source of bleeding can usually be determined and stopped by undergoing an endoscopy, (using a camera that either is passed through the mouth or the anus).  Even more rarely, an operation may be required to stop the bleeding.
