Changes in Urinary Iodine Levels Following Bariatric Surgery
Authors' conclusion
In an iodine-sufficient area, bariatric surgery does not cause iodine deficiency nor clinically significant changes in thyroid function. Different surgical procedures with different anatomical alterations in the gastrointestinal tract do not significantly affect iodine status.
Study context
- Population
- Adults who underwent laparoscopic SG or laparoscopic RYGB surgery
- Participants
- 85 adults
- Exposure
- 3 months after bariatric surgery vs baseline
- Outcome
- Change in urinary iodine concentrations (UIC)
- Follow-up
- 3 months after surgery
Main finding
As reported in the abstract
Spot UIC · 3 months postoperatively
P < 0.001
Observational data: associations, not effects.
Further findings
TSH · 3 months postoperatively · significant decrease
P < 0.001
| Outcome | Baseline | 3 months | P value |
|---|---|---|---|
| BMI · 3 months postoperativelySignificant decrease | mean 44.0 ± 6.2 | mean 35.8 ± 5.9 | P < 0.001 |
BMI, urinary iodine concentrations (UIC) and thyroid stimulating hormone (TSH) by type of surgery · before and after surgery
- Did not differ based on the type of weight loss surgery
