Abstract

Roux-en-y Gastric Bypass is a very common surgical procedure in managing morbid obesity. Approximately 303,890 roux-en-y surgeries were performed in the United States in between the years of 2012 to 2017, and the number is steadily increasing as more Americans are diagnosed with obesity.i

This featured case report describes a 52-year-old female presenting with complications seven years following Roux-en-y gastric bypass. Four years post-operatively, she presented to the ER with a pelvis fracture. It was incidentally found that she had osteoporosis with a t-score of -2.9. It was also found that her bone mineral density (BMD) for women for her age was low with a z-score of -3.5 and her 10-year probability of getting fractures was high with a Fracture Risk Assessment Tool (FRAX) score of 6.2%. Seven years following Roux-en-y gastric bypass, she presented to our primary care office with Vitamin B12 deficiency and secondary hyperparathyroidism due to Vitamin D deficiency. We attempted to correct the deficiencies with high dose of Vitamin D, Vitamin B12, and calcium citrate. Eight months later, the B12 levels was normalized, but the secondary hyperparathyroidism and Vitamin D deficiency were not corrected. This case illustrates the complications that can occur following a Roux-en-y Gastric Bypass, importance of supplement compliance, and proper follow-up with Roux-en-y patients.
