Abstract
Objective:
Analyze if bariatric surgery could induce changes in comorbidity rates and compare the outcomes of two different kinds of bariatric surgery interventions.
Materials and Methods:
A 5-year before-after study on a cohort of obese patients who were subjected to bariatric surgery in the years 2013–2015 was conducted. Comorbidities considered in this study were arterial hypertension, hyperlipidemia, diabetes, sleep apnea, osteoarthritis, gastroesophageal reflux, urinary incontinence, and lower limb ulcers.
Results:
One hundred thirty-six subjects were enrolled in the final sample: 110 underwent gastric banding and 26 underwent gastric bypass. Data have shown that both interventions provide an important weight loss and gastric bypass is more effective in permanent weight reduction; bariatric surgery is effective in reduction of sleep apnea, osteoarthritis, gastroesophageal reflux, urinary incontinence, and lower limb ulcers. Frequencies of presentation of hypertension, diabetes, and hypercholesterolemia in patients who underwent gastric banding follow a “U-shaped trend.”
Conclusions:
Bariatric surgery for obese subjects is an effective solution for weight loss, but it has also proved to be an effective way to reduce comorbidities, with an important reduction in frequencies of all pathologies and an improvement in blood tests. Gastric bypass is superior to gastric banding in comorbidity reduction.
