Post-Surgical Nutritional Care Flashcards

A patient 3 weeks after Roux-en-Y gastric bypass reports dizziness, sweating, and rapid heartbeat 30 minutes after eating a sweetened yogurt. What is the most likely cause?

Answer: Early dumping syndrome

Early dumping syndrome occurs 15-30 minutes after eating high-sugar foods due to rapid gastric emptying into the small intestine.

What is the recommended daily protein intake for most patients following bariatric surgery?

Answer: 60-80 grams

Most post-bariatric guidelines recommend 60-80 grams of protein daily to preserve lean body mass during rapid weight loss.

Why are patients advised to avoid drinking liquids within 30 minutes of meals after bariatric surgery?

Answer: Liquids can flush food through the pouch, reducing satiety and increasing intake

Drinking with meals accelerates pouch emptying, which reduces fullness and can lead to overeating or dumping symptoms.

Which form of calcium is preferred for supplementation after gastric bypass, and why?

Answer: Calcium citrate, because it does not require stomach acid for absorption

Calcium citrate is absorbed without gastric acid, which is reduced after bypass procedures.

A sleeve gastrectomy patient at 6 months reports hair loss. Which nutritional factors should the counselor evaluate first?

Answer: Protein, zinc, and iron intake

Telogen effluvium after bariatric surgery is commonly linked to inadequate protein, zinc, and iron.

During the immediate post-operative diet progression, which stage typically comes directly after clear liquids?

Answer: Full liquids

The standard progression is clear liquids, then full liquids, then pureed, then soft, then regular textures.

Why is vitamin B12 supplementation lifelong for gastric bypass patients?

Answer: Reduced intrinsic factor and stomach acid impair B12 absorption permanently

Bypassing the stomach reduces intrinsic factor and acid needed to release and absorb B12 from food.

A patient 18 months post-bypass reports shakiness, confusion, and hunger 2 hours after a high-carbohydrate meal. What condition should the counselor suspect?

Answer: Late dumping syndrome (reactive hypoglycemia)

Late dumping occurs 1-3 hours after eating when an exaggerated insulin response causes reactive hypoglycemia.

Which micronutrient deficiency after bariatric surgery can cause Wernicke encephalopathy if untreated?

Answer: Thiamine (vitamin B1)

Thiamine deficiency, often triggered by persistent vomiting, can rapidly progress to Wernicke encephalopathy.

A counselor notices a patient is consuming milkshakes and melted ice cream to cope with restriction. What is this behavior called?

Answer: Soft calorie or liquid calorie syndrome (eating around the surgery)

Consuming calorie-dense liquids bypasses the restrictive effect of surgery and undermines weight loss.

How should iron and calcium supplements be scheduled after bariatric surgery?

Answer: Taken at least 2 hours apart because calcium inhibits iron absorption

Calcium competes with iron for absorption, so doses should be separated by about 2 hours.

Which eating behavior is most important for preventing food getting stuck after sleeve gastrectomy?

Answer: Chewing thoroughly and eating slowly with small bites

Thorough chewing and slow eating prevent obstruction and discomfort in the narrow sleeve.

A patient asks why carbonated beverages are discouraged after bariatric surgery. What is the best response?

Answer: Gas can cause pouch discomfort, bloating, and may encourage pouch stretching over time

Carbonation introduces gas that distends the small pouch, causing pain and potentially contributing to stretching.

Which lab finding at a 12-month follow-up most suggests inadequate protein intake in a bariatric patient?

Answer: Low serum albumin

Low albumin reflects protein-energy malnutrition, a key monitoring marker after bariatric surgery.

A duodenal switch patient is at highest risk for deficiency of which vitamins compared with other bariatric procedures?

Answer: Fat-soluble vitamins A, D, E, and K

The duodenal switch causes significant fat malabsorption, greatly increasing risk of fat-soluble vitamin deficiencies.

A patient 2 weeks post-surgery reports drinking only 500 mL of fluid daily. What is the counselor's primary concern?

Answer: Dehydration, the most common cause of readmission after bariatric surgery

Inadequate fluid intake leads to dehydration, which is the leading reason for hospital readmission after bariatric surgery.

Why should NSAIDs like ibuprofen generally be avoided after Roux-en-Y gastric bypass?

Answer: They increase the risk of marginal ulcers at the anastomosis

NSAIDs significantly raise the risk of marginal ulceration at the gastrojejunal anastomosis.

A pregnant patient 1 year after gastric bypass asks about nutrition. What is the most important counseling point?

Answer: She needs closer micronutrient monitoring, including B12, iron, folate, and vitamin D

Pregnancy after bariatric surgery requires enhanced micronutrient surveillance because deficiencies can harm fetal development.

Which protein source is most appropriate during the full-liquid stage after surgery?

Answer: Whey protein isolate shakes or skim milk

Liquid protein sources such as whey isolate shakes meet protein goals while respecting the liquid-only texture stage.

A patient reports intolerance to red meat 4 months after sleeve gastrectomy. What should the counselor recommend first?

Answer: Substitute moist, softer protein sources like fish, eggs, and ground poultry

Dense, dry meats are commonly poorly tolerated, so moist and softer proteins help maintain intake.
