Effective weight loss was achieved in morbidly obese patients after undergoing  bariatric surgery .
A substantial majority of patients with diabetes , hyperlipidemia , hypertension , and obstructive sleep apnea experienced complete resolution or improvement
CONTEXT About 5 % of the US population is morbidly obese .
This disease remains largely refractory to diet and drug therapy , but generally responds well to bariatric surgery .
OBJECTIVE To determine the impact of bariatric surgery on weight loss , operative mortality outcome , and 4  obesity  comorbidities ( diabetes , hyperlipidemia , hypertension , and obstructive sleep apnea ) .
Intra-abdominal pressure, sagittal abdominal diameter and obesity comorbidity.
OBJECTIVES To determine relationship of intra-abdominal pressure to central obesity and the comorbidity of obesity . DESIGN Non-r and omized , prospect i ve . SETTING University hospital , operating room . SUBJECTS Eighty-four anaesthetized consecutive patients prior to gastric bypass for morbid obesity and five non-obese patients before colectomy for ulcerative colitis . MAIN OUTCOME MEASURES Weight , body mass index ( BMI ) , co-morbid history , sagittal abdominal diameter , waist : hip ( W : H ) ratio and urinary bladder pressure , as an estimate of intra-abdominal pressure . RESULTS Urinary bladder pressure was greater in the obese than the non-obese ( 18 + /- 0.7 vs. 7 + /- 1.6 cm H2O , P < 0.001 ) , correlated with sagittal abdominal diameter ( r = + 0.67 , P < 0.001 ) and was greater ( P < 0.05 ) in patients with , than those without , morbidity probably ( hypoventilation , gastroesophageal reflux , venous stasis , stress incontinence , incisional hernia ) or possibly ( hypertension , diabetes ) due to increased abdominal pressure . W : H ratio correlated with urinary bladder pressure in men ( r = + 0.6 , P < 0.05 ) but not women ( r = -0.3 ) . CONCLUSIONS Increased sagittal abdominal diameter was associated with increased intraabdominal pressure which contributed to obesity-related comorbidity . W : H ratio was not a reliable indicator of intra-abdominal pressure for women who often have both peripheral and central obesity . Further studies are needed to evaluate the relationship between intra-abdominal pressure and Type II diabetes and hypertension
