Comparative Study
The effect of surgical weight reduction on functional status in morbidly obese patients with low back pain.
Although low back (LBP) pain is not a life-threatening disease, it is a source of significant discomfort and disability and accounts for work absences. It has been shown previously that morbid obesity is associated with increased frequency of LBP and that surgical weight loss improves the symptomatology. However, there are no studies to quantitatively assess the exact degree of functional disability caused by severe obesity and the degree of improvement of LBP that follows weight loss from bariatric surgery. ⋯ Surgical weight loss significantly improves the degree of functional disability of morbidly obese patients suffering from LBP.

Obstructive sleep apnea (OSA) is a common condition in morbidly obese patients, with the reported prevalence ranging from 12-78%. There is increasing recognition of the need to diagnose and treat/manage OSA both preoperatively and postoperatively. Nasal CPAP is the preferred treatment of OSA; however, weight loss is associated with a reduction in required pressures. We evaluated the CPAP pressure requirements in a group of patients undergoing rapid weight loss following Roux-en-Y gastric bypass. ⋯ CPAP pressure requirements change considerably in bariatric surgery patients undergoing rapid weight loss. Auto-titrating PAP devices have promise for facilitating the management of CPAP therapy during this time. Consideration should also be given to the use of autotitrating PAP units as the treatment of choice in these patients.
