Micronutrients & recovery

Bariatric surgery significantly increases the risk of bone loss and fractures, particularly in malabsorptive procedures, due to reduced calcium absorption and secondary hyperparathyroidism, which is not fully mitigated by standard calcium and vitamin D supplementation.

If you have bariatric surgery, especially a malabsorptive type like gastric bypass, your risk of bone fractures increases significantly. Standard calcium and vitamin D supplements often fail to prevent this bone loss. You need specialized, long-term bone health monitoring beyond standard care.

GoodSupportsHIGH confidence
There is a dramatic 33% decrease in Ca absorption at 6 months after RYGB surgery... There is no evidence that serum 25-hydroxy-vitamin D [25(OH)D] levels or dietary supplementation of vitamin D or Ca intake modifies the extent of bone loss... Fracture risk is increased after BS, but this is generally limited to malabsorptive procedures.
