Acute renal failure is typical in patients with renal cortical necrosis, with associated complications (eg, hyperkalemia, fluid overload). Chronic renal failure, occurring in 30-50% of patients, requires dialysis and transplantation.
The average hospital stay is 1 to 3 nights which varies depending on type of surgery and your overall condition. Duodenal switch surgery: 2 to 3 days; Gastric bypass surgery: 2 to 3 days; Gastric sleeve surgery: 2 to 3 days; Mini gastric bypass: 2 to 3 days; Gastric banding surgery (LAP-BANDÂ®): 1 day or less; Gastric Balloon: Same-day (outpatient)
Gastric bypass patients must learn to eat much smaller portions. After gastric bypass surgery, patients can remain in the hospital for two to six days. However, recovery in the hospital requires more than just staying in bed. Approximately four to six hours after the surgery, patients usually have to get out of bed for short periods of time to prevent blood clots from forming in the legs.
