Background Physical activity after bariatric surgery is associated with sustained weight loss and improved quality of life. Some bariatric patients engage insufficiently in physical activity. The aim of this study was to examine whether and to what extent both physical activity and exercise cognitions have changed at one and two years post-surgery, and whether exercise cognitions predict physical activity. Methods Forty-two bariatric patients (38 women, 4 men; mean age 38 ± 8 years, mean body mass index prior to surgery 47 ± 6 kg/m²), filled out self-report instruments to examine physical activity and exercise cognitions pre- and post surgery. Results Moderate to large healthy changes in physical activity and exercise cognitions were observed after surgery. Perceiving less exercise benefits and having less confidence in exercising before surgery predicted less physical activity two years after surgery. High fear of injury one year after surgery predicted less physical activity two years after surgery. Conclusion After bariatric surgery, favorable changes in physical activity and exercise cognitions are observed. Our results suggest that targeting exercise cognitions before and after surgery might be relevant to improve physical activity.

BackgroundPhysical activity after bariatric surgery is associated with sustained weight loss and improved quality of life. Some bariatric patients engage insufficiently in physical activity. This may be due to exercise cognitions, i.e., specific beliefs about benefits of and barriers to physical exercise. The aim of this study was to examine whether and to what extent both physical activity and exercise cognitions changed at 1 and 2 years post-surgery and whether exercise cognitions predict physical activity.MethodsForty-two bariatric patients (38 women, 4 men; mean age 38 ± 8 years, mean body mass index prior to surgery 47 ± 6 kg/m2) filled out self-report instruments to examine physical activity and exercise cognitions pre- and post-surgery.ResultsA large increase in physical activity and favorable changes in exercise cognitions were observed after surgery, viz. a decrease of fear of injury and embarrassment and an increase of the perception of exercise benefits and confidence in exercising. Perceiving less exercise benefits and having less confidence in exercising before surgery predicted less physical activity 2 years after surgery. High fear of injury 1 year after surgery predicted less physical activity 2 years after surgery.ConclusionsAfter bariatric surgery, favorable changes in physical activity and beliefs about the benefits and barriers of exercising are observed. Our results suggest that targeting exercise cognitions before and after surgery might be relevant to improve physical activity.

Background: Lymphedema (LE) is a chronic condition of swelling due to lymphatic impairment and is characterized by edema and fibro-adipose tissue deposition. LE may be caused by an anomalous development of the lymphatic system, known as primary LE, or may develop secondary to traumatic, infectious, or other external events. Knowledge is increasing about the plural and bidirectional relationship between LE and obesity. The rate of obesity is increasing worldwide, and bariatric surgery offers the most effective and durable treatment, as this surgery exhibits positive effects on many obesity-related diseases. We explored whether bariatric surgery could improve leg volumes in morbidly obese LE patients. Methods and Results: Between 2013 and 2019, 829 patients were hospitalized in our Center of Expertise for Lymphovascular Medicine for intensive treatment of their LE. Nine patients with end-stage primary, secondary, or obesity-induced LE underwent a bariatric procedure related to their morbid obesity. Data concerning age, gender, medical diagnosis, LE stage, type of bariatric treatment, body weight, body mass index (BMI), and limb volumes were retrospectively collected from the patient files. At the individual patient level, body weight, BMI, leg volumes, and their percent reduction between presurgery and postsurgery were calculated. At the group level, paired sample t-tests were conducted to compare the mean body weight, BMI, and volumes of both legs between postsurgery and presurgery. The data demonstrate a significant decrease in body weight, BMI, and leg volumes in morbidly obese end-stage primary, secondary, and obesity-induced LE patients following bariatric surgery. Conclusions: Our multiple case study indicates that bariatric surgery provides a good indication for concomitant treatment of morbid obesity and LE.
