Key result
Continued nutritionist follow-up after bariatric surgery was associated with an average 2.39% greater increase in total weight loss compared to no follow-up.
Why the study?
During long-term follow-up after bariatric surgery, weight loss varies between subjects, prompting this assessment of weight loss patterns and associated factors over time.
What factors are associated with different patterns of weight change after bariatric surgery in adult patients with obesity?

Comparison
Laparoscopic Roux-en-Y gastric bypass vs sleeve gastrectomy and clinical factors associated with weight loss
Design
Longitudinal study
Follow-up
Up to 36 months

What factors are associated with different patterns of weight change after bariatric surgery in adult patients with obesity?
Mean Difference: 2.39 (95% CI 0.62–4.17)
p-value: p=0.014
Modifiable factors such as nutritional follow-up, pre-surgical weight loss, and physical activity are associated with significant changes in total and excess weight loss after bariatric surgery.
Carrillo et al. (2021) conducted a cohort in Obesity (n=196). Nutritionist follow-up vs. No continued nutritionist follow-up was evaluated on Change in percentage of total weight loss (%TWL) (Coefficient 2.39, 95% CI 0.62-4.17, p=0.014). Continued nutritionist follow-up after bariatric surgery was associated with an average 2.39% greater increase in total weight loss compared to no follow-up.
