Weight Loss Surgery Gurgaon: 3 Bariatric Options Explained

What Is Bariatric Surgery?

Bariatric surgery is a group of operations that change the digestive system to help people lose weight and improve obesity-related diseases. Most are performed laparoscopically, through small cuts and a camera, which means less pain, a shorter stay in hospital and faster recovery than open surgery.

The operations work through a mix of mechanisms. Some reduce the size of the stomach so you feel full on smaller portions. Others also change how food is absorbed. Importantly, they alter gut hormones that control hunger and blood sugar, which is why many patients see their diabetes improve soon after surgery, often before much weight has been lost.

Who May Be a Candidate?

Eligibility is assessed individually. In India, commonly used guidelines suggest that surgery may be considered for adults with:

• A body mass index (BMI) of 35 or above, with or without obesity-related conditions.
• A BMI of 32.5 or above with conditions such as type 2 diabetes, hypertension, sleep apnoea or fatty liver, in line with Asian-specific recommendations.
• Previous serious attempts at weight loss through diet, exercise and medical supervision without sustained results.
• No uncontrolled psychiatric illness, active substance abuse or medical conditions that make surgery unsafe.
• Willingness to follow long-term diet, supplement and follow-up requirements.

BMI is calculated as weight in kilograms divided by height in metres squared. People of South Asian origin tend to develop metabolic disease at lower BMI levels, which is why lower thresholds are used.

Types of Weight Loss Surgery

Sleeve gastrectomy. About 75 to 80 percent of the stomach is removed, leaving a narrow, banana-shaped sleeve. It reduces how much you can eat and lowers the hunger hormone ghrelin. It is one of the most commonly performed procedures and does not reroute the intestines.

Roux-en-Y gastric bypass. A small stomach pouch is created and connected directly to the middle of the small intestine, bypassing part of the stomach and the upper intestine. It restricts intake and reduces absorption, and it is often favoured for patients with severe reflux or significant diabetes.

Mini gastric bypass or one-anastomosis gastric bypass. A variation that uses a single connection to the intestine, with a shorter operating time. Your surgeon will explain whether it suits you.

Adjustable gastric band and other options. Bands are now rarely used because of long-term complications. Endoscopic and balloon-based procedures exist for selected patients who do not meet criteria for surgery or need a temporary measure.

The best operation is the one matched to your health, eating pattern, diabetes status, reflux and personal goals, chosen after discussion with the bariatric team.

Benefits of Bariatric Surgery

• Substantial and sustained weight loss, often 25 to 35 percent of body weight depending on the procedure.
• Remission or major improvement of type 2 diabetes in many patients.
• Better control of blood pressure and cholesterol.
• Reduction or resolution of sleep apnoea and fatty liver disease.
• Relief of joint pain and improved mobility.
• Improved fertility and better outcomes in women with PCOS.
• Better quality of life, energy and mental wellbeing.
• A lower risk of heart attack and, in studies, longer life expectancy in people with severe obesity.

Risks and Complications

All surgery carries risk, and bariatric surgery is no exception, although serious complications are uncommon in experienced centres.

• Bleeding, infection or leaks at the staple lines.
• Blood clots in the legs or lungs.
• Narrowing or blockage of the new connections, which can cause vomiting.
• Acid reflux, especially after sleeve gastrectomy.
• Gallstones forming with rapid weight loss.
• Nutritional deficiencies of iron, vitamin B12, calcium, vitamin D, folate and protein if supplements are not taken.
• Dumping syndrome after gastric bypass, with nausea, sweating and palpitations after sugary food.
• Hair thinning and loose skin, which are common but usually temporary or manageable.
• Weight regain if eating patterns, activity and follow-up are neglected.

Preparing for Surgery

Preparation takes several weeks and is as important as the operation itself.

1. 1Detailed evaluation. Blood tests, ECG, ultrasound abdomen and, where needed, upper endoscopy, sleep study and cardiac or lung assessment.
2. 2Dietitian consultation. You learn portion control, protein targets and the staged diet that follows surgery.
3. 3Psychological assessment. Screening for binge eating, depression or anxiety helps prepare you for lifestyle change.
4. 4Stopping smoking. Smokers have higher rates of wound problems and ulcers and are usually asked to stop several weeks before surgery.
5. 5Pre-operative weight loss. A short, supervised low-calorie diet can shrink the liver and make surgery safer.
6. 6Medication review. Diabetes medicines, blood thinners and others may need adjustment.

What Happens During and After Surgery

The operation usually lasts one to two hours under general anaesthesia. Most patients stay in hospital for two to three days. Walking begins on the same day to reduce the risk of clots.

Diet progresses in stages: clear liquids first, then full liquids, then pureed foods, then soft foods, and finally regular textures over six to eight weeks. Protein comes first at each meal, and fluids are sipped between meals rather than with them.

You will take lifelong supplements, commonly a multivitamin, calcium with vitamin D, iron and vitamin B12, as advised by your team. Follow-up visits and blood tests are scheduled at regular intervals in the first year and then annually.

Keeping the Weight Off

Surgery is a tool, not a cure. Long-term success depends on habits.

• Eat slowly, chew thoroughly and stop at the first sign of fullness.
• Prioritise protein, vegetables and whole foods; limit sugary drinks, sweets and fried snacks.
• Aim for at least 150 minutes of physical activity weekly, adding strength training to preserve muscle.
• Keep every follow-up appointment and take supplements without fail.
• Seek support early if you notice emotional eating or weight regain.

Non-Surgical Options and Why They Matter

Surgery is not the first step for everyone. Before it is recommended, most patients are encouraged to try a structured, medically supervised approach.

• Supervised diet and exercise. A dietitian-led plan with realistic calorie and protein targets and a progressive activity program.
• Behavioural support. Identifying emotional eating, night eating and trigger foods through counselling.
• Medicines. Prescription anti-obesity medicines and newer injectable therapies may help some patients lose weight, though results often reverse if the medicine is stopped.
• Treating underlying causes. Thyroid disease, PCOS, sleep apnoea and certain medicines can all promote weight gain and should be addressed.

If these steps do not produce adequate, lasting results, or if the health risks of obesity are already high, surgery becomes a reasonable next step. It works best as part of a long-term plan, not a last resort taken without preparation.

Life After Surgery: Setting Expectations

The first three to six months bring the fastest weight loss, along with changes you may not expect. Appetite is smaller and tastes may change. Some patients feel tired or cold while the body adjusts to lower intake, and hair thinning is common between three and six months after surgery but usually recovers when protein and vitamins are adequate. Emotional adjustment matters too: as the body changes, relationships with food, family and social events may feel different, and counselling or a support group can help. Regular exercise protects muscle and bone, improves mood and makes long-term maintenance far easier.

Is Surgery Safe?

When performed by an experienced surgical team in a hospital with full intensive care and anaesthesia support, modern bariatric surgery has a safety record comparable to common operations such as gallbladder removal. The risks of untreated severe obesity, including diabetes complications and heart disease, are often greater than the risks of the operation.
