Methodology
Review of 136 gastric bypass patients in follow-up at one bariatric center, plus a longitudinal series of 16 patients with measurements before surgery and 6 and 24 months after.
Key Findings
13 patients (9.6%) had copper deficiency, most with anemia, low white cells or nerve problems. In the 16 followed patients, copper and ceruloplasmin activity fell after surgery (P<0.05) while zinc did not, giving an incidence of 18.8%.
Conclusions
Copper deficiency after gastric bypass can be serious and irreversible if untreated, so frequent monitoring is warranted.
Limitations
Single center; the longitudinal group was only 16 people; no control group.
Supplements Studied
determined to be 9.6% and 18.8%, respectively
