Your surgeon will perform bariatric surgery if your weight loss efforts through lifestyle changes and medications have been unsuccessful. And keep in mind, the bariatric surgery is the first step, not the last, to changing your life and keeping better health throughout.
Bariatric surgery, or weight-loss surgery, helps the patients with extreme obesity issues to lose weight. The surgery is an option, as any bariatric surgeon will thoroughly advocate, only if the patient is not able to lose weight through diet and exercise, or has serious health problems caused by obesity and needs immediate measures to curb the weight issues.
There have been research studies that show that a bariatric surgery or weight-loss surgery has the ability to reverse the debilitating effects of being extremely overweight on health and quality of life.
Bariatric surgeons believe that a body suffering from longstanding obesity defends itself against weight loss by drastically reducing its metabolic rate. This effect is negated after the surgery as it permanently changes the contours of the digestive tract. This surgery is always against obesity as a first step — bariatric surgeons are able to guide the extremely overweight and obese people to a better quality of life.
Research studies have shown that obesity surgery has some long-lasting benefits to the patients’ health and quality of life. When compared with patients who haven’t undergone a gastric sleeve surgery, or a gastric bypass surgery, or even a lap-band surgery, the ones who underwent a weight-loss surgical procedure fared much better physically, emotionally and socially.
The studies also show that these patients who underwent a gastric bypass surgery, or a gastric sleeve surgery, or a lap-band surgery, rated themselves healthier and were less likely to report problems with mobility, pain, daily activities, social interactions and feelings of depression and anxiety — among other factors that can compromise a person’s well-being.
Surgically induced weight loss has other equally significant medical benefits — normalizing blood sugar, blood pressure and blood lipid levels and curing sleep apnoea. Even though bariatric surgery has not been proven to cure Type 2 diabetes, it nearly always puts the disease into remission, and slows or prevents life-threatening damage that can be caused to heart and blood vessels.
Even in the small percentage of patients who lose only little weight after bariatric surgery, there are significant metabolic benefits. Studies have shown that even a ‘modest’ weight loss of 5–10 percent results in reduction of cardiovascular risk factors and blood sugar abnormalities.
The two most popular surgical techniques — the gastric bypass and the gastric sleeve — have metabolic benefits that are above and beyond the benefit of weight loss, as both methods permanently reduce the size of the stomach. However, the gastric band procedure or the lap bad surgery, which is reversible, lacks these benefits unless patients achieve and maintain significant weight loss.
