There are many who find themselves struggling with severe obesity and do not know how they can shed their excessive weight. Bariatric surgery includes a variety of procedures performed on people suffering from obesity. Weight loss is achieved by reducing the size of the stomach with a gastric band. A portion of the stomach is removed by resecting and re-routing the small intestine to a small stomach pouch (Gastric Bypass Surgery). Long-term studies show that the procedure can cause significant weight loss, recovery from diabetes and improvement in cardiovascular risk factors.
CMRI is proud to be one of the few hospitals in Eastern India to facilitate Obesity management through Bariatric Surgery.
How is the Body Mass measured?
Body Mass Index (BMI) – WHAT DOES IT MEAN?
|22.5 to 27.5||Overweight|
|27.5 to 37.5||Obese|
|37.5 and above||Severely Obese|
When is Bariatric Surgery needed?
For those who are severely overweight (roughly 30 kg or more than ideal and have been unsuccessful at dietary / behavioural approaches to weight loss), a Laparoscopic Weight Loss Surgery may be considered).
Surgery is recommended if the BMI is 37.5 or BMI is above 32.5 with co-morbidities like Diabetes, Sleep Apnea, Insomnia, Depression etc.
Conventional ways of losing weight are diet and exercise, which is a temporary development, and the lost weight usually comes back adding extra pounds. For those who are seriously overweight, losing weight is not just a cosmetic procedure.
Abdominal fat or visceral fat is metabolically active and secretes hormones that lead to inflammation, heart disease, diabetes etc. In addition, excessive weight diminishes almost every aspect of health from reproductive and respiratory function to memory and mood. It also interferes with sexual functions.
All these co-morbidities can be improved or cured by Bariatric Surgery.
Permanent Cure of Diabetes
Obesity surgery, which is now called “Metabolic Surgery,” is the best mean of diabetic control in 80% of patients.
Routine Tests are done prior to surgery on all patients to evaluate pre-operative co-morbidities and the surgery is planned accordingly to avoid complications and ensure a safe post-operative period.
Laparoscopic Sleeve Gastrectomy
In this procedure, the stomach is divided vertically and converted into a narrow tube (the size of a banana), capable of holding 80 to 90 ml. of food at a time.
Laparoscopic ROUX-EN-Y Gastric Bypass
Gastric Bypass involves creating a small pouch by dividing the stomach. The small intestine is divided and is joined with the new stomach pouch. This allows the food to go straight from the stomach pouch into the small intestine, which causes it to bypass the lower stomach and the duodenum (the first segment of the small intestine). This process greatly reduces the number of calories the body absorbs.
This is the most effective weight loss procedure.
Mini Gastric Bypass
The Mini-Gastric Bypass (MGB) is a recently introduced procedure being increasingly adopted in many countries around the world. During this surgery, the stomach is divided and a small stomach is created holding 200 to 250 ml of food at a time. A portion of intestine is joined to the divided portion of stomach creating passage for food to pass into the intestine.
RESULTS OF BARIATRIC SURGERY
The effectiveness of Bariatric Surgery depends on the success of the surgical procedure and the ability of the patient to change the dietary or eating behaviour. Patients choosing Bariatric Surgery have to be committed to long-term lifestyle changes, including dietary and behavioural modifications. Patients can expect gradual weight loss up to 2 years. They may lose upto70-80 % of their excess weight within 18 months after the surgery.
