“…In addition, the number of studies was insufficient to conduct a meta‐analysis. Most recently, a number of controlled trials have described the effects of exercise training on various outcomes related to body composition, physical capacity or health status . Therefore, a systematic updated overview of this topic, complemented by a meta‐analysis, is relevant.…”

Effectiveness of exercise training after bariatric surgery—a systematic literature review and meta‐analysis

We aimed to conduct a systematic review and meta-analysis of controlled trials assessing exercise training programs in patients with obesity undergoing bariatric surgery. We systematically searched exercise training studies performed after bariatric surgery published up to June 2017. Studies reporting changes in body composition, physical fitness, functional capacity, objectively measured physical activity, quality of life or relevant health outcomes were included. The review protocol is available from PROSPERO (CRD42017069380). Meta-analyses were conducted using random-effects models when data were available from at least five articles. Twenty articles were included, describing 16 exercise training programs, of which 15 were included in the meta-analysis. Overall, exercise training was associated with higher weight loss (mean difference: -2.4 kg, 95% CI: -4.2; -0.6, I = 49%, n = 12), higher fat mass loss (-2.7 kg, 95% CI: -4.5; -1.0, I = 50%, n = 8) and improved VO max and functional walking (standardized mean difference: 0.86, 95% CI: 0.29; 1.44, I = 57%, n = 6; 1.45, 95% CI: 0.32; 2.58, I = 89%, n = 6, respectively). Exercise training was not associated with lean body mass changes. In conclusion, exercise training programs performed after bariatric surgery were found effective to optimize weight loss and fat mass loss and to improve physical fitness, although no additional effect on lean body mass loss was found.

“…In a 24-month, randomized, controlled study evaluating the effects of an intervention including a combination of high vitamin D and calcium supplementation with exercise post-bariatric surgery, the intervention group had attenuated increase in bone turnover markers and less pronounced bone loss as compared with the non-intervention group [128]. In another study, a weightbearing and aerobic exercise intervention program postbariatric surgery resulted in less pronounced bone loss which was associated with preservation of muscle mass [129].…”

The interaction between obesity and bone metabolism is complex. The effects of fat on the skeleton are mediated by both mechanical and biochemical factors. Though obesity is characterized by higher bone mineral density, studies conducted on bone microarchitecture have produced conflicting results. The majority of studies indicate that obesity has a positive effect on skeletal strength, even though most likely the effects are site-dependent and, in fact, obese individuals might be at risk of certain types of fractures. Mechanical loading and higher lean mass are associated with improved outcomes, whereas systemic inflammation, observed especially with abdominal obesity, may exert negative effects. Weight loss interventions likely lead to bone loss over time. Pharmacological treatment options seem to be safe in terms of skeletal health; however, the skeletal effects of bariatric surgery are dependent on the type of surgical procedure. Malabsorptive procedures are associated with higher short-term adverse effects on bone health. In this narrative review, we discuss the effects of obesity and weight loss interventions on skeletal health.

“…Indeed, the duodenum is the site where active calcium transport can be enhanced to achieve sufficient calcium absorption when dietary calcium intake is low. After RYGB, bone loss is consistently observed during the first two years ( Campanha-Versiani et al, 2017 ; Frederiksen et al, 2016 ; Obinwanne et al, 2014 ; Casagrande et al, 2012 ; Shanbhogue et al, 2017 ; Yu et al, 2015 ; Bazzocchi et al, 2015 ; Kaulfers et al, 2011 ; Maghrabi et al, 2015 ; Carrasco et al, 2014 ; Vilarrasa et al, 2013 ; Muschitz et al, 2016 ; Hsin et al, 2015 ; Muschitz et al, 2015 ; Bredella et al, 2017 ). Longer follow-up for three to six years still showed persistent bone loss, although the number of studies is limited ( Rousseau et al, 2016 ; Vilarrasa et al, 2013 ; Elias et al, 2014 ; Raoof et al, 2016 ).…”

Thin bones: Vitamin D and calcium handling after bariatric surgery

et al. 2018

View full text Add to dashboard Cite

Bariatric surgery has proven to be a valuable treatment option for morbid obesity. However, these procedures can lead to impaired intestinal absorption of calcium and vitamin D, thereby challenging calcium homeostasis and possibly contributing to bone loss leading to an increased fracture risk. Besides calcium and vitamin D malabsorption, hormonal changes occurring after surgery can also be the source of observed bone loss. In this review, first, a case report will be discussed, highlighting the relevance of this topic. Afterwards, changes in bone density and fracture risk, after the two most performed types of bariatric surgery, Sleeve Gastrectomy (SG) and Roux-en-Y Gastric Bypass (RYGB) will be discussed. In addition, we discuss the putative underlying mechanisms leading to bone changes based on both preclinical and clinical observations. Nonetheless, it is clear further research is needed to further elucidate the exact mechanisms of bone loss following bariatric surgery and subsequently identify potential treatment options for bone preservation.

Abstract: The supervised exercise program attenuated lumbar spine and right hip BMD loss and improved LM in the arms and overall MS but did not affect bone remodeling.
