Bariatric surgery is associated with lower incidence of carpal tunnel syndrome
Authors' conclusion
BS was found to be associated with reduced incidence of developing CTS. There is a dose-response association where greater weight loss following BS is protective of developing CTS.
Study context
- Population
- Patients with obesity who underwent bariatric surgery; mean age 41.2 (SD 12.9) years, 68.6% female, mean pre-operative BMI 42.9 (SD 5.4); most underwent restrictive surgery
- Participants
- 6,124 patients
- Exposure
- Carpal tunnel syndrome (CTS) incidence 5 years pre- vs post-bariatric surgery
- Outcome
- Incidence of carpal tunnel syndrome (CTS)
- Follow-up
- 5 years pre- and post BS
Main finding
As reported in the abstract
Incidence of CTS · 5 years pre vs post BS
P < 0.001
Observational data: associations, not effects.
Further findings
Characteristics of patients developing CTS after bariatric surgery (BS) vs those who did not
- Patients developing CTS after BS were older, with higher prevalence of hypertension and DM before BS, higher BMI and excess body weight at every time point, and lower BMI reduction
Weight regain and CTS
- Weight regain was not associated with increased incidence of CTS
Excess weight loss and CTS
- Direct correlation between excess weight loss and greater reduction in CTS incidence
