Dr Himanshu Yadav is among the top Bariatric Surgeon in India. Dr Himanshu started and established world class Bariatric (weight loss) surgery services in Agra. Metabolic and bariatric surgery is the treatment of morbid obesity and obesity-related diseases and conditions that limit the amount of food the stomach can hold. It limits the number of calories absorbed, by surgically reducing the stomach’s capacity to a few ounces. Candidates for bariatric surgery have a body mass index (BMI) of 40 or more, or a BMI of 35 or more with an obesity-related disease, such as type 2 diabetes, heart disease or sleep apnoea. Advanced Bariatric surgery can improve or resolve more than 30 obesity-related conditions, including type 2 diabetes, heart disease, sleep apnoea, hypertension and high cholesterol. Bariatric procedures also often cause hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery).
Bariatric/ Weight-Loss Surgery Treatments:
- Gastric Band: Adjustable gastric banding / gastric bands (sometimes known as a lap band) is a restrictive Bariatric surgical procedure. A silicone band is placed around the upper part of the stomach, creating a small pouch above the band that is about the size of a golf ball. This forms a large pouch below the band. This is helpful in reduction of the excessive fat or weight of stomach.
- Gastric Bypass: Gastric bypass surgery refers to a surgical procedure in which the stomach is divided into a small upper pouch and a much larger lower "remnant" pouch and then the small intestine is rearranged to connect to both. Surgeons have developed several different ways to reconnect the intestine, thus leading to several different gastric bypass (GBP) procedures. Any GBP leads to a marked reduction in the functional volume of the stomach, accompanied by an altered physiological and physical response to food.
- Gastric Sleeve: Gastric sleeve surgery is a restrictive procedure only. Two thirds of the stomach are resected and removed, leaving a smaller stomach in the shape of a sleeve. The portion of the stomach removed produces a hormone that stimulates appetite and hunger. Removing this portion of stomach results in a significant reduction in appetite.
- Gastric Balloon: For many patients with a BMI (body mass index) of 27 - 35 surgery is not always available or recommended according to the NICE (National Institute of Clinical Excellence) guidelines, as patients with a lower BMI do not normally qualify for weight loss surgery. The gastric balloon is a soft, expandable intragastric (inside the stomach) device that is temporarily inserted into the stomach.
- Conversion Surgery: Surgery patients are not always successful in reaching their weight loss goals. Reasons for post-operative weight loss failure can include problems with the original surgery, as well as the patient’s inability to comply with necessary life style changes.
- Gastric Band Failure: Gastric bands for obesity may help people lose weight, but patients frequently experience problems with the device years after they've had the procedure. Major complications include things like infection or erosion of the band.
- Gastric Bypass Failure: If you begin to regain weight after gastric bypass surgery, you may have a sense of what's causing your weight gain. However, you may need a more thorough evaluation to determine what factors — medical, psychological, lifestyle — are involved in the weight gain. You may have gained weight after gastric bypass surgery because of changes in your stomach and intestine that allow you to eat more and absorb more calories. It's also possible that your diet and exercise habits have slipped, in which case you must typically lose the regained weight the old-fashioned way, both by reducing your calorie intake and increasing your physical activity.
- Gastric Sleeve Failure: A paucity of such studies exists, with a few recent reports and presentations pointing to failure rates as high as 30 percent. Similar to other bariatric surgery procedures, sleeve gastrectomy failure is likely to be multifactorial and related to a combination of technical, physiological, and psychological parameters, such as gradual sleeve dilation, hormonal adaption, and recurrence of improper eating behaviours, respectively.

Benefits of Bariatric/ Weight-Loss Surgery:
- Resolves type 2 diabetes in 73% – 83% of patients
- Cuts the risk of developing coronary heart disease in half
- Effective treatment for obstructive sleep apnoea
- Patients can improve life expectancy by 89%
- Long term effectiveness – maximum weight loss 1-2 years after surgery and maintain a substantial weight
- Patients may lose 30% – 50% of their excess weight 6 months after surgery and 77% of their excess weight as early as 12 months after surgery
