What Is Bariatric Surgery?

Bariatric surgery, also known as weight loss surgery, serves as an effective solution for individuals grappling with severe obesity and struggling to shed excess weight through alternative approaches. This surgical intervention offers a methodical and controlled avenue for weight reduction, coupled with the management of one’s body mass index post-procedure.

Modern weight loss surgeries employ minimally invasive techniques, conducted via laparoscopic surgery. These bariatric surgical methods achieve weight loss by both limiting the stomach’s food capacity and inducing malabsorption, effectively combining gastric restriction and malabsorption mechanisms. Additionally, bariatric surgeries frequently trigger hormonal alterations that facilitate weight loss. The most prevalent procedures include gastric bypass, sleeve gastrectomy, adjustable gastric banding, and biliopancreatic diversion with a duodenal switch.

What Are The Symptoms Of Obesity?

Obesity is widely recognized as a significant contemporary health threat. Failing to adopt preventative measures can heighten the risk of future weight-related issues. Numerous indicators and symptoms can help identify obesity.

Primarily, excess weight or obesity is often linked to the measurement known as the body mass index (BMI). BMI, an acronym for “body mass index,” gauges body weight relative to height, offering a valuable tool for classifying individuals as underweight, within a healthy range, or overweight. As per the National Institutes of Health guidelines, a BMI falling between 18.5 and 25 signifies normal weight, while a range of 25 to 30 indicates overweight, and a BMI of 30 or above signifies obesity.

Why Bariatric Surgery Required For The Weight Loss

Patients with a BMI of 35 or higher, showing an upward trend, along with the presence of obesity-related diseases or conditions, are candidates for weight loss through bariatric surgery. Obesity-induced changes in metabolic processes in these individuals lead to the excessive production of ketone bodies, accompanied by symptoms such as acidosis and hyperglycemia. Surgical intervention becomes imperative in such cases, as it serves to reverse the metabolic dysregulation stemming from obesity.

Who Should Go For Bariatric Surgery?

Candidates for bariatric surgery should fall within the age range of 20 to 40 years. Their Body Mass Index (BMI) should ideally fall between 35 and 40. Additionally, they should present an obesity-related condition such as diabetes mellitus, cardiovascular disease, or hypertension. Bariatric surgery can also be considered for individuals who are within 5 pounds of their target weight.

Prospective bariatric surgery candidates should demonstrate a willingness to engage in a minimum of ninety minutes of weekly exercise. They should also exhibit prior short-term success in earnest weight loss endeavors. Other crucial factors include a history of overweight status exceeding five years, the ability to commit to lifestyle and dietary modifications, and the absence of autoimmune diseases.

Types Of Bariatric Surgery


Bariatric Surgery Procedure

Restrictive Technique: Lap Gastric Band

This form of surgery entails the placement of a band in the upper section of the stomach. This action establishes a narrow outlet, restricting the quantity of food ingested per meal, resulting in a sensation of fullness with smaller portions. The aim is to curtail daily calorie consumption while avoiding significant weight fluctuations.

Bariatric Surgery Procedure

Gastric band surgery offers several advantages, such as a lasting restoration of the stomach’s regular size, a notably shorter recovery timeframe compared to alternative options, the absence of any surgical cutting or stapling in the body, and the surgeon’s ability to manage the size of the outlet.

Malabsorptive Procedures-Roux -En- Y Gastric Bypass

Roux-en-Y Gastric Bypass is a gastrointestinal procedure exclusively employed for weight loss. This surgery is conducted through minor incisions in the skin, enabling the reduction in stomach size and reshaping. A Roux limb, approximately 15 cm (about 5.91 in) in length, is fashioned and connected to the jejunum, a portion of the intestine situated beyond the stomach. This configuration ensures that most ingested food bypasses the stomach, consequently diminishing calorie absorption

Benefits Of Roux-En-Y Include

Roux-en-Y Gastric Bypass surgery serves as a weight loss procedure that transforms a severely obese individual’s large stomach into two smaller ones. This involves the removal of a portion of the large stomach, which is then connected to the initial segment of the small intestine before being reattached. This connection redirects food through a shortened small intestine, promoting weight loss by regulating appetite and discouraging overeating.

Vertical gastrectomy, a surgical technique, permanently reduces stomach size by excising most of it. This approach leads to weight loss without impacting appetite. The procedure is minimally invasive, conducted through laparoscopy, involving just five small incisions. The achieved weight loss typically surpasses that attained through gastric band surgery and sleeve gastrectomy.

Gastric banding offers a notable advantage in that it allows precise control over the pouch outlet size. This permits adjustments to be made easily, altering the passage size for food leaving the stomach. Furthermore, this method eliminates the need for an external drain, a feature some patients find aesthetically displeasing and uncomfortable.

Take Care After Bariatric Surgery

The surgical procedure, while effective in achieving weight loss, doesn’t ensure success for everyone. Sustaining long-term body weight necessitates a commitment to a healthy lifestyle. For instance, experiencing early satiety, which involves feeling full after consuming small food portions, facilitates adherence to a low-calorie diet by curbing calorie intake. This prolonged sense of fullness acts as a deterrent against overeating and contributes to minimizing weight regain
