Obesity is no longer just a lifestyle concern – it is a serious health condition that affects millions of people worldwide, including in India. Carrying excess weight puts tremendous strain on the body and increases the risk of life-threatening diseases such as diabetes, heart problems, hypertension, joint pain, and even certain types of cancer. For many individuals, despite trying strict diets, exercise routines, and medications, losing weight and keeping it off becomes a constant battle.
This is where bariatric surgery for weight loss in Delhi NCR comes as a life-changing option. Bariatric surgery is not just about reducing weight for cosmetic purposes; it is about restoring health, energy, and quality of life. Patients who undergo this procedure often find themselves free from long-term health issues, enjoying higher self-confidence, and living longer, healthier lives.
Understanding Bariatric Surgery
So, what is bariatric surgery? In simple terms, bariatric surgery is a medical procedure that helps people lose weight by making changes to their digestive system. It works either by limiting the amount of food the stomach can hold, or by changing the way food is digested and absorbed. The result is reduced calorie intake, which leads to gradual and sustainable weight loss.
Bariatric surgery is usually recommended for individuals who:
Have a BMI (Body Mass Index) of 35 or more, or a BMI between 30–34.9 with serious obesity-related health conditions.
Have tried and failed with other weight-loss methods like diet, exercise, and medications.
Are motivated to make long-term lifestyle changes after surgery.
Key Facts About Bariatric Surgery:
It is performed using minimally invasive techniques such as laparoscopy, which ensures smaller cuts, less pain, and faster recovery.
It helps in long-term weight management, unlike temporary solutions like fad diets.
It is a scientifically proven way to reduce or even reverse conditions like type 2 diabetes, high cholesterol, and sleep apnea.
It is not just about losing weight but also about gaining back control over health.
Types of Bariatric Surgery
Bariatric surgery is not a single procedure but a group of surgeries designed to help people achieve long-term weight loss. The type of surgery recommended depends on factors such as your current weight, medical conditions, and lifestyle. Dr. Aloy Mukherjee offer advanced techniques to ensure safe and effective results.

Here are the most common types of bariatric surgery in Delhi:
1. Gastric Bypass Surgery (Roux-en-Y Gastric Bypass)
This is one of the most popular forms of bariatric surgery. The surgeon creates a small pouch in the stomach and connects it directly to the small intestine. Food bypasses a portion of the stomach and intestine, which means:
You feel full faster.
Your body absorbs fewer calories.
It helps control blood sugar levels effectively, making it an excellent choice for patients with type 2 diabetes.
2. Sleeve Gastrectomy
In this procedure, about 70–80% of the stomach is removed, leaving behind a sleeve-shaped smaller stomach. It works in two ways:
Reduces the amount of food you can eat.
Lowers the production of the hunger hormone (ghrelin), which naturally reduces appetite.
It is simpler than gastric bypass and offers impressive weight-loss results.
3. Adjustable Gastric Banding
Here, a silicone band is placed around the upper part of the stomach, creating a small pouch. The band can be tightened or loosened by injecting or removing fluid. This method:
Controls how much food the stomach can hold.
Is reversible and adjustable.
However, it may result in slower weight loss compared to other methods.
4. Biliopancreatic Diversion with Duodenal Switch (BPD/DS)
This is a more complex surgery where part of the stomach is removed, and a large portion of the intestine is bypassed. It leads to significant weight loss and is particularly effective for patients with severe obesity. However, it requires lifelong monitoring and nutritional supplements.
Each of these procedures has its pros and cons. The best surgeon for bariatric surgery in Delhi, like Dr. Aloy Mukherjee, carefully evaluates your health and recommends the surgery that matches your needs and goals.
Benefits of Bariatric Surgery
Choosing the best weight loss surgery in Delhi is not just about shedding extra kilos; it is about transforming your life in multiple ways. The benefits extend beyond appearance, improving both physical health and emotional well-being.

1. Effective and Sustainable Weight Loss
Unlike diets that often result in temporary weight loss, bariatric surgery provides long-term results. Patients often lose 60–80% of their excess weight within 12–18 months after surgery.
2. Improvement in Obesity-Related Diseases
Bariatric surgery is a proven treatment for many medical conditions linked to obesity. It can:
Put type 2 diabetes into remission or significantly reduce dependence on medications.
Lower blood pressure and cholesterol levels, reducing the risk of heart attack and stroke.
Improve sleep apnea, helping patients sleep better and feel more energetic.
Relieve joint pain, as less weight reduces stress on knees, hips, and spine.
3. Better Quality of Life
Patients report improved mobility, increased energy levels, and higher self-confidence. Everyday activities like climbing stairs, exercising, or even playing with children become easier.
4. Emotional and Psychological Benefits
Obesity often causes anxiety, depression, and low self-esteem. After bariatric surgery, many patients feel emotionally stronger and more positive about life.
5. Long-Term Health Protection
Maintaining a healthy weight after surgery reduces the risk of developing chronic diseases such as heart disease, liver disease, and even certain cancers.
Mechanism of Bariatric Surgery
To understand why bariatric surgery is so effective, it’s important to know how it works inside the body. Unlike dieting or exercise, which rely entirely on willpower and lifestyle changes, bariatric surgery alters the digestive system itself, making weight loss more natural and sustainable.

There are two main mechanisms:
1. Restriction
Restriction means reducing the size of the stomach so it can hold less food. For example, in sleeve gastrectomy, the stomach is reshaped into a smaller tube or “sleeve.” As a result:
You feel full much sooner.
You eat smaller portions without feeling deprived.
Calorie intake decreases automatically, without strict dieting.
2. Malabsorption
Some surgeries, like gastric bypass or BPD/DS, change the way food travels through the intestines. The food bypasses part of the small intestine, which:
Reduces the number of calories and nutrients absorbed.
Helps in faster and more significant weight loss.
Requires patients to take supplements to prevent deficiencies.
3. Hormonal Changes
Bariatric surgery also changes hormone levels in the gut, especially ghrelin, the hormone responsible for hunger. This naturally reduces appetite, improves insulin sensitivity, and even helps in controlling type 2 diabetes.
Together, these mechanisms explain why bariatric surgery is one of the most effective long-term solutions for obesity, especially under the care of the best surgeon for bariatric surgery in Delhi.
