Morbid obesity is defined by the National Institutes of Health as being 100 pounds or more above your ideal body weight. It also includes having a Body Mass Index of 40 or greater, or 35 or greater with a condition such as Diabetes 2, Heart Disease or Osteoarthritis, among others.

Patients with these conditions may benefit the most from bariatric surgery; the weight loss achieved as a result of the surgery can decrease the effects of these problems very quickly and give the patient the opportunity to resume a healthier lifestyle. Patients with Type 2 diabetes can see a resolution of the disease, often in very short order. Those patients with heart disease will take a great strain off of their hearts as their weight drops quickly and dramatically, blood pressure is often improved as well, leading to less medication. Patients suffering with osteoarthritis or joint pain will find relief from the pain, and able to return to life and work in a more productive and self confident mode.

Those patients suffering from acid reflux and sleep apnea also report a decrease in these ailments, which may be linked to more serious health issues. The cancer risk of morbid obesity is also reduced.
