Obesity is a medical condition caused by excessive weight gain, which poses a grave health risk to persons, and sets the foundation for a variety of debilitating diseases such as diabetes, hypertension and cardiovascular disease. Bariatric obesity surgery is a procedure performed on people who are dangerously obese, and who do not respond to traditional, non-surgical weight-loss treatment.
Bariatric obesity surgery encompasses several surgical techniques, some done through the laparoscopic method and others carried out via open surgery; some of which are reversible and others which aren't. Probably 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.For instance, bariatric obesity surgery reduces complications associated with diabetes, heart problems, 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 is recommended only for people whose body weight exceeds the perfect by more than 50 kilograms and who suffer from other obesity related illness. Also, consultants usually 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 a few issues, and only if the proposed benefits are perceived to outweigh the risks, that doctors 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 complications encountered by a minority of patients who undergo bariatric obesity surgery.
In preparation for bariatric obesity surgery, patientsare requested to obtain a nutritional evaluation, many different blood tests, and a full medical check-up, so that it will reduce potential post-surgery issues that may otherwise occur.
After bariatric obesity surgery, overeating is automatically curbed, as excess food intake usually causes the patient to display nausea-like signs. After undergoing the said surgery, most patients are advised to take a regular dose of multivitamins so as to compensate for the minimized absorption of essential nutrients. Once weight-loss is achieved, so they can keep up with the desired level of weight, people are advised to follow prudent eating practices, so as to obtain the optimal advantages that bariatric obesity surgery promises.
