Gastric Bypass

Nowadays, weight management is the biggest problem for people from all age groups. Weight loss surgery options are preferred when alternative means of weight loss such as exercise, diet management, and so on fail to work.

Gastric bypass, also known as Roux-en-Y Gastric Bypass, is one of the most popular weight loss surgery options during which the size of the stomach is decreased. The reduced size of the stomach allows for reduced consumption of food by the patient, which in turn, results in gradual weight loss.

Other popular weight loss surgery options include:

  • Sleeve gastrectomy
  • Adjustable gastric band
  • Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

Of all the bariatric procedures, gastric bypass is the most preferred options for weight loss because of the greater possibility of positive outcomes. Moreover, there are no major side effects of gastric bypass.

 What are the criteria for gastric bypass surgery?

 Not everyone is an ideal candidate for gastric bypass surgery. People with a body mass index (BMI) of 40 or more and with a history of heart disease, obesity, and obstructive sleep apnea are mostly recommended gastric bypass surgery.

Lap Gastric Banding

Obesity has become a growing concern for individuals in the present generation. Surgical intervention is one of the options for weight loss that obese individuals can opt for.

People prefer to choose surgical options for weight loss mostly when they fail to achieve satisfactory results through other methods such as exercise and diet control. There are different types of surgeries for weight loss, demand for which has steadily risen since last few years. One such type of surgery is the gastric banding procedure.

Gastric banding procedure is a minimally invasive surgery conducted with the help of a laparoscope. This surgery involves the placement of a weight loss band that restricts the passage of the food from the stomach to the intestine. It is commonly called as a lap-band or laparoscopic adjustable gastric band (LAGB).

The weight loss band used during the gastric banding procedure is actually an inflatable silicone device with a tendency to expand and contract. Your doctor can adjust the weight loss band from the outside such that only small amounts of food can pass through the stomach.

  • The adjustable gastric band makes you feel full earlier and thereby, aids in gradual weight loss. The gastric band may not result in quick weight loss and you must modify your lifestyle, follow a proper diet and exercise regularly.
  • Gastric banding procedure is an alternative to vertical sleeve gastrectomy, in which a large portion of the stomach in removed to aid in weight loss. Gastric band removal is possible, but you are not advised to opt for it upon reaching the targeted body weight.
Sleeve Gastrectomy

Gastric sleeve procedure, also known as sleeve gastrectomy, involves surgical removal of part of a stomach. This procedure is a permanent one and intends to result in drastic weight loss in individuals suffering from morbid obesity.

During the gastric sleeve procedure, the left side of the stomach is cut and the size is reduced to just 25 percent of its original size. The resulting stomach looks like a banana-like “sleeve.”

The resulting vertical gastric sleeve limits the intake of food due to reduced production of gastric enzymes and digestive juices. You may feel full after eating small amounts of food. This is also known as a “restrictive procedure” as it restricts the amount of food that you can consume at a time. This procedure is performed laparoscopically and is irreversible in nature.

Is it safe to have sleeve gastrectomy?

Gastric sleeve procedure is recommended to individuals whose body mass index (BMI) is 40 or greater than 40. It is a completely safe procedure and is minimally invasive in nature.

When performed correctly, laparoscopic sleeve gastrectomy improves a number of obesity-related medical conditions, including low back pain, arthritis, hypertension, cardiac disorders, obstructive sleep apnea, dermatitis due to skin folds, urinary incontinence, and metabolic syndrome.
