Increased joint pain after massive weight loss: is there an association with joint hypermobility?

Long-term chronic joint pain after sleeve gastrectomy and its influence on clinical and psychological outcomes

INTRODUCTION

Bariatric surgery (BS) is effective in improving chronic joint pain (CJP). However, the long-term effects on this comorbidity are poorly understood.

OBJECTIVES

To determine the prevalence of CJP in a sample of patients who had undergone BS with a minimum follow-up of 18 months. To determine whether or not there was any relationship between CJP and clinical or psychological outcomes after BS.

MATERIAL AND METHODS

Cross-sectional study. The Lattinen index (LI) was used to evaluate CJP, using the cut-off point of 10 to define significant CJP (SCJP).

RESULTS

Of the 110 subjects assessed, 31.2% (35/110) had SCJP. The patients with SCJP were older (57.4±13 vs 47.8±11.6 years; p<0.0001) and more time had elapsed since their BS (105.6±54.3 vs 78.5±39 months; p=0.023). The last BMI was higher in subjects with SCJP (35±5 vs 33.3±6.9kg/m²; p=0.05) and the percentage of patients who took significant regular exercise was lower (2.9% vs 68%; p<0.0001). Trauma problems after BS were more common in subjects with SCJP (61.8% vs 22.7%; p<0.0001). More patients with SCJP met depression criteria (47.1% vs 5.3%; p<0.0001) and/or were treated with antidepressants (38.2% vs 17.3%; p=0.003). Patients with SCJP reported fewer hours of sleep (6±1.4 vs 6.8±1.2h; p=0.003).

CONCLUSIONS

SCJP is highly prevalent in patients who have had BS once they reach the weight plateau phase. There is an association between having SCJP and worse psychological and functional status, with potential detrimental metabolic effects.
