Obesity is a medical condition caused by excessive weight gain, which poses a grave health risk to people, and sets the foundation for a variety of debilitating diseases such as diabetes, hypertension and heart disease. Bariatric obesity surgery is a procedure performed on individuals who are dangerously obese, and who don’t respond to traditional, non-surgical weight-loss treatment.
Bariatric obesity surgery encompasses numerous surgical techniques, some done through the laparoscopic method and others carried out via open surgery; most of which are reversible and others which are not. The most commonly used methods include adjustable gastric banding, vertical banded gastroplasty, biliary-pancreatic diversion with duodenal switch, Roux-en-Y gastric bypass surgery and mal-absorption operations. Other lesser known methods include but aren’t limited to, sleeve gastrectomy, the use of an intragastric balloon and implantable gastric stimulation, to name buta few.
The benefits of bariatric obesity surgery are many, as obesity impacts all aspects of an individual’s life, be it physical, psychological or social.As an example, bariatric obesity surgery reduces complications associated with diabetes, heart disease, breathing difficulties and even sleep apnea. However bariatric obesity surgery is only advocated when a low-calorie diet, steady exercise, medication and counseling prove to be ineffective, and it’s recommended only for people whose bodyweight exceeds the ideal by more than 50 kilograms and who suffer from other obesity related illness. Also, consultants generally hold the opinion that bariatric obesity surgery is of limited use to those, whose obesity is a result of a hormonal or a metabolic imbalance.
As with all surgical procedures, bariatric obesity surgery too, sometimes pose some complications, and only if the proposed benefits are perceived to outweigh the risks, that medical professionals advise patients to go ahead with the said procedure. Infections, incisional hernias, gastric dumping syndrome (which causes nausea and/or diarrhea), and pneumonia are a few of the common problems encountered by a minority of patients who undergo bariatric obesity surgery.
In preparation for bariatric obesity surgery, patientsare requested to get a nutritional evaluation, many different blood tests, and a full medical check-up, so as to minimize potential post-surgery issues that may otherwise occur.
After bariatric obesity surgery, overeating is automatically curbed, as excess food intake normally causes the patient to show nausea-like signs or symptoms. After undergoing the said surgery, most patients are advised to take a regular dose of multivitamins so as to compensate for the decreased absorption of essential nutrients. Once weight-loss is achieved, so they can keep up with the desired level of weight, individuals are advised to follow prudent eating practices, so as to obtain the optimal benefits that bariatric obesity surgery promises.
