Two weeks after gastric bypass, a patient reports dizziness, sweating, and cramping shortly after eating a sugary dessert. What is the most likely cause?
Answer: Early dumping syndrome
Early dumping syndrome occurs 15-30 minutes after eating high-sugar foods when hyperosmolar contents rapidly enter the small intestine.
Which postoperative complication after bariatric surgery is a life-threatening emergency typically presenting with tachycardia, fever, and abdominal pain in the first week?
Answer: Anastomotic or staple-line leak
A leak from the anastomosis or staple line allows gastric contents into the abdomen, and persistent tachycardia is often the earliest sign.
A gastric bypass patient develops burning epigastric pain and is found to have an ulcer at the connection between the pouch and small intestine. Which behavior most increases this risk?
Answer: Smoking and NSAID use
Marginal ulcers at the gastrojejunal anastomosis are strongly associated with smoking and NSAID use, both of which impair mucosal healing.
Years after Roux-en-Y gastric bypass, a patient presents with intermittent severe abdominal pain. Which delayed surgical complication should the counselor recognize as unique to bypass anatomy?
Answer: Internal hernia through a mesenteric defect
Rerouted bowel in Roux-en-Y anatomy creates mesenteric defects through which intestine can herniate and twist, sometimes years later.
Which complication is most specifically associated with adjustable gastric banding?
Answer: Band slippage or erosion into the stomach
Gastric bands can slip out of position or erode through the stomach wall, which are leading reasons for band removal.
A sleeve gastrectomy patient reports new or worsening heartburn after surgery. Why is this a recognized issue with this procedure?
Answer: The high-pressure sleeve can worsen or cause gastroesophageal reflux
The narrow, high-pressure sleeve can increase reflux, and severe GERD may require conversion to gastric bypass.
Why does rapid weight loss after bariatric surgery increase the risk of gallstones?
Answer: Rapid fat mobilization increases cholesterol saturation of bile
Rapid weight loss raises cholesterol concentration in bile and reduces gallbladder motility, promoting stone formation.
