People with clinically severe obesity are at great medical risk of disability or premature death. Obesity has been the cause for prematurely deaths each year due to obesity related complications, or co-morbidities. At the top of the list of obesity related co-morbidities are adult onset diabetes and high blood pressure. High blood pressure caused by clinically severe obesity can contribute to heart attacks, congestive heart failure and stroke. Health concerns such as sleep apnea, asthma, low-back pain, urinary stress incontinence and severe acid reflux are also a result of increased weight. Significant weight loss can often ease these conditions or reverse them completely.
