To date, majority of patients who have undergone bariatric surgery operations have either successfully reversed, eliminated or significantly alleviated obstructive sleep apnea, hypertension, hyperlipidemia and diabetes (Buchwald, et al. , 2004). This implies that weight loss is related with important enhancements in health-correlated complications. Specifically, patients commonly benefit from significant enhancements in mobility, sleep apnea, hypertension and glycemic control (Anderson & Wadden, 1999).
A study on complications following bariatric surgery operations indicates that an overwhelming number of patients (90%) had encountered zero complications, while only 1 percent suffered two complications (Anderson & Wadden). There is also only a 1 percent risk involved in the two most severe complications—deep venous thrombosis and gastrointestinal tract leak combined (Anderson & Wadden). Furthermore, operative mortality in agencies that specialize in bariatric surgery is only from 1. 0–1. 5 percent (Anderson & Wadden, 1999).
Quality of life is very likely to be improved for most bariatric surgery patients notwithstanding possible negative outcomes such as the nuisance of dietary restrictions, the anxiety and pain of surgical operations and other complications. Relief from fatal co-morbid ailments, a 45-kg decrease in weight and enhanced economic and social opportunities together significantly improve a person’s quality of life. It should also be noted that some people seem to born already with a tendency to obesity, which is willingly nourished by today’s high-fat, sedentary lifestyle.
Severely overweight individuals who look for weight reduction therapy experience considerable depression or other psychological problems. After a successful bariatric surgical operation, there are likely improvements in one’s perception of well-being, self-confidence, capability to interact with others, physical self-image, social function and the time used for physical and recreational activities. Finally, economic and productivity prospects are improved, such as new and better work.
