Unfortunately, previously reliable sources that address this topic, eg MedlinePlus at the US National Institutes of Health, are inaccessible. This is a medical site, albeit highly technical, that outlines what would be done in hospital:
Recovery from an abdominal wound will depend on where the person was shot, the type of firearm used, (edit: also the type of ammunition used), and what organs were damaged. If there was stomach, pancreatic, intestinal, and/or bladder perforation, organ contents would spill into the abdomen and lead to peritonitis and sepsis within hours. Injury to the kidney, spleen, and/or liver, which are highly vascular organs, would cause massive internal bleeding. "A fair bit of blood loss" is on the serious end which would likely require blood and/or plasma transfusions. Unless the abdominal wound missed all major organs, and/or was a surface wound, someone could be laid up for several days weeks.
